Yes, the /proc directory basically contains information on the running kernel 
and should never be backed up.

If you've got a Linux Server then lookup BackupPC on sourceforge and you'll

Like yourself I'm thinking of moving from tripwire to aide on our production 
servers this summer. So I have an interest in this working ;-)

First check your selinux setup with sestatus. That will tell you whether it is 
in enforcing or permissive mode or even disabled.

If it's permissive or disabled them selinux wouldn't appear to be your problem 
as then it shouldn't stop anything from working.

If it's in enforcing mode then maybe it is.

If it's in enforcing or permissive mode then it will put its error messages 
in /var/log/audit/audit.log

Check there for AVC messages from aide.

Tony.

[CentOS] Vsftpd problem

[Tony Molloy]

Hi all,

I have a filesystem which I need to make available through ftp ( vsftpd ).  I 
have this as separate filesystem as it needs to be available through apache 
and NFS also. It's our local mirror.
 
I've set up vsftpd and put a test directory in /var/ftp/pub and it works. 
However I can't seem to get it to see the separate /mirrors filesystem.

I've tried using symlinks as below in /var/ftp/pub.

drwxr-xr-x 3 root root 4096 Jun 26 10:53 .
drwxr-xr-x 3 root root 4096 Jun 22 12:11 ..
-rw-r--r-- 1 root root   25 Jun 22 12:21 .message
drwxr-xr-x 2 root root 4096 Jun 22 15:25 TEST
lrwxrwxrwx 1 root root8 Jun 26 10:53 mirrors -> /mirrors

I this case the TEST directory works but the mirrors directory does not.

ftp> cd mirrors
550 Failed to change directory.

I've also tried using mount --bind to remount the the /mirrors filesystem 
as /var/ftp/pub/mirrors. When I do this I can see the contents 
of /var/ftp/pub/mirrors

drwxr-xr-x  2 root root 4096 Jun 22 15:25 TEST
drwxr-xr-x 13 root root 4096 Jun 23 07:54 mirrors

ls  -al /var/ftp/pub/mirrors/

drwxr-xr-x 13 root   root   4096 Jun 23 07:54 .
drwxr-xr-x  4 root   root   4096 Jun 26 11:04 ..

drwxr-xr-x  4 apache apache 4096 Sep 21  2006 custom-repos

However when I try to ftp to it I can't see the mirrors directory

-rw-r--r--1 ftp  ftp25 Jun 22 12:21 .message
drwxr-xr-x2 ftp  ftp  4096 Jun 22 15:25 TEST

Finally I've tried mounting it directly under /var/ftp/pub/mirrors

-rw-r--r--  1 root root   25 Jun 22 12:21 .message
drwxr-xr-x  2 root root 4096 Jun 22 15:25 TEST
drwxr-xr-x 13 root root 4096 Jun 23 07:54 mirrors


But when I ftp into the box again I can't see the mirrors directory

ftp> ls
227 Entering Passive Mode (10,220,1,157,168,142)
150 Here comes the directory listing.
drwxr-xr-x2 ftp  ftp  4096 Jun 22 15:25 TEST
226 Directory send OK.

 
Is this a permissions problem or does vsftpd not allow separate filesystems to 
be seen.

Regards,

Tony

I don't "hate" it. I just forget that it causes problems sometimes when it's

Not meant like that. It's just that I always forget to check SELinux when I 
have these problems and go checking lots of other things. Instead what I 
should do is set SELinux to permissive and make sure it's not a SELinux 
mis-configuration.

[CentOS] Configure WiFi at install on CentOS Stream 9

[Tony Molloy]

Hi,
I'm trying to install CS-9 and need to have WiFi setup on boot.

I've tried installing with KVM as a test but only get the choice of an
ethernet connection at install time.

I've tried installing onto a spare laptop and it gives a choice of ethernet
or WiFi for network connections. I choose WiFi and it allows me to
configure the WiFi. It detects the network and the IP-address. However when
I reboot the laptop there is no WiFi connection.

Any suggestions.

Thanks,

Tony

Not possible as far as I know ;-)

Remove the samba rpms and install the samba3x rpms from CentOS 5.5

This will give you samba3x-3.3.8-0.52.el5_5.2.x86_64 which works as a PDC with 
Windoze 7 clients.

There are two sets of samba packages included with Centos 5.5; Look in the 
source repo.

samba-3.0.33-3.28.el5.src.rpm  ( the default )  

and

samba3x-3.3.8-0.51.el5.src.rpm


You have to remove the samba packages to install the samba3x packages
which are required to work with windoze 7 clients.

You could try your local mirror ;-)

When the rsync is finished check the contents of the centos/5 directory. There 
should be links there to the point release in use.

In my case although i've got the 5.4 rpms rsynced from my local mirroor the 
links in that directory still link to 5,3 

e.g.

[r...@thomond centos]# cd 5
[r...@thomond 5]# ls -al
total 44
drwxrwxr-x  2 1000 1000 4096 Apr  1  2009 .
drwxr-xr-x 11 1000 1000 4096 Sep 28 23:29 ..
lrwxrwxrwx  1 1000 1000   14 Oct 21 11:04 addons -> ../5.3/addons/

That means that the default Centos-Base.repo file in /etc/yum.repos.d will 
still use 5.3.

When 5.4 is finally released and all the mirrors have synced then the links 
will link to 5.4

Hope this helps,

Tony

Ditto.

The problem is not with updated systems but with newly installed systems. 
yum-priorities is missing from newly installed 5.4 systems. It's fine with 
updated systems.

[CentOS] Amavisd and ClamAV

[Tony Molloy]

Hi,

I want to move my mail server from sendmail to postfix over christmas. I've 
got a test server running with the following:

postfix dovecot postgrey amavisd-new clamav spamassassin

I've followed the howto's on the wiki  with the 
exception that I installed amavisd-new and clamav from the EPEL repo rather 
than rpmforge.

Things work OK with the exception of clamav. When I start  clamav I get the 
following error.

[r...@newgoext ~]# service clamd.amavisd start
Starting clamd.amavisd: ERROR: Missing argument for option at line 2
ERROR: Can't open/parse the config file /etc/clamd.d/amavisd.conf
   [FAILED]

As this is a test server I'v set selinux to permissive so it doesn't look like 
a selinux problem.

Thanks,

Tony

Yep. It was a parse error in the installed file not an open error.

cat /etc/clamd.avisd.conf

# Use system logger.
#LogSyslog

# Specify the type of syslog messages - please refer to 'man syslog'
# for facility names.
LogFacility LOG_MAIL

# This option allows you to save a process identifier of the listening
# daemon (main thread).
PidFile /var/run/amavisd/clamd.pid

# Remove stale socket after unclean shutdown.
# Default: disabled
#FixStaleSocket

# Run as a selected user (clamd must be started by root).
User amavis

# Path to a local socket file the daemon will listen on.
LocalSocket /var/spool/amavisd/clamd.sock


When I commented out LogSyslog and FixStaleSocket it started ok.

Thanks for stating the obvious sometimes that's the hardest thing to see ;-)

It's a selinux denial. Selinux is permissive/enforcing on the system.

# sestatus

will tell you which.

It's got something to do with samba "comm="smbd""
trying to access the file "path="/proc/sys/fs/binfmt_misc"" Don't know why it 
would want to do that.

Try this

# sealert -b

This will dispaly all the AVC's graphically. Look for one from smbd.  This 
will give you the full AVC and possibly suggest a way to fix it.

[CentOS] Problem with Full install of 5.2, missing rpm

[Tony Molloy]

Hi,

I did a standard i386 install of 5.2 on a test machine. Then I ran the 
following command

yum  install  \*

and got the following error.

Error: Missing Dependency: pilot-link-devel >= 0.11.8 is needed by package 
gnome-pilot-devel

Checking my local repo and my usual upstream mirrors for pilot-link-devel it's 
not there.

[EMAIL PROTECTED] CentOS]# locate pilot-link-devel | grep centos
/mirrors/centos/5.1/os/i386/CentOS/pilot-link-devel-0.11.8-16.i386.rpm
/mirrors/centos/5.1/os/x86_64/CentOS/pilot-link-devel-0.11.8-16.i386.rpm
/mirrors/centos/5.1/os/x86_64/CentOS/pilot-link-devel-0.11.8-16.x86_64.rpm
/mirrors/centos/5.2/os/x86_64/CentOS/pilot-link-devel-0.11.8-16.i386.rpm
/mirrors/centos/5.2/os/x86_64/CentOS/pilot-link-devel-0.11.8-16.x86_64.rpm

As you can see from the above pilot-link-devel is present in both i386 and 
x86_64 repos for 5.1 but only in the x86_64 repo for 5.2

It's not really a problem I can just leave out gnome-pilot-devel.

Is this an oversight or is it deliberate.

Thanks for all the good work. Now to get on to my rack of PE2950's

Regards,

Tony

That's fine. It's not just my local repo it's both my usual upstream repos ( 
ftp.heanet.ie and ftp.mirrorservice.org ) as well. I'll just wait till they 
sync later today. 

Thank you,

I spoke too soon!!!

The problem is not that pilot-link is missing that's there OK . The problem is 
that pilot-link-devel is missing.

I had no trouble copying it or linking it.

ln -s /bin/false /usr/bin/false


ls  -al /usr/bin/false
lrwxrwxrwx 1 root root 10 Jul  5 17:47 /usr/bin/false -> /bin/false

So that's a quick workaround

If the dependancy is purely on /usr/bin./false then when you copy it I think 
yum should find it. 

The problem would be if yum checks it's db to see if it has previously 
installed /usr/bin/false and find that it hasn't. In that case it won't wok.

Why don't you try it and see what happens.

[CentOS] Yun Update problem

The rpm packages are in my local repo.

Is this just a case of my local upstream mirrors being out of sync or have I 
got a bigger problem.

Thanks for the reply,

That's exactly what I did but till have the same problem. It may be that the 2 
upstream repos that I sync my local repo to are corrupted. This is the first 
time I've used the x86_64 repos. When I get a chance I'll try and use a 
different repo and see what happens.

These are internal machines so I had to set up a proxy to get external access.

Then I removed my local repos  and used the "mirrorlist" line in the repos 
definitions and the "fastestmirror" plugin and the update went OK. So it must 
be a problem with my 2 upstream mirrors. I'll get onto the mirror masters and 
try and sort it out with them.

< lots snipped >

So it would appear that lots of download sites have the wrong rpms then.

I got the good rpms from the following repos

 * fasttrack: ftp.tudelft.nl

I installed fail2ban from rpmforge and it has no dependencies. I use it with 
the default CentOS firewall

I installed on some x86_64 systems but you can specify noarch on the install 
line. I don't know the precedence of i386 and noarch.

[CentOS] Applications on different deskops at startup

[Tony Molloy]

Hi,

I've just converted my laptop to Centos 6 from Fedora ( gnome 3 made 
the latest fedora unusable ) and I have one problem.

I have several desktops with applications running on them, mainly 
terminals. At login all the terminals start on desktop 1. How do I get 
them to start on the desktop they were running on at logoff. That's how 
it worked on Fedora 13/14 so it must be popssible ;-) just can't find 
the magic.

Thanks,,

Tony

Thanks for the various suggestions I'll try them out today. I just 
thought that since CentOS 6 was based on Fedora 13 that it would just 
be some setting that I had missed.

First I'm no SELinux expert ;-( but I've ben following this thread 
with interest. It apears to be going around in circles.

The only time I've come across a file_t type is when I have something 
on a machine that SELinux doesn't know about. That is SELinux has no 
policy for it. An example would be if I create a new top level 
directory when I install a machine. SELinux knows nothing about that 
directory name and has no preset type for it so it gets a label of 
file_t or default_t. Doing a relabel in that case will have no affect on 
the file label as SELinux still doesn't have a policy for it.

So the question is how did your file get the file_t type in the first 
place. You say it is generated from a cgi script run from apache.

So is this the default apache which comes with CentOS

What is the context of the apache executable. It should be
-rwxr-xr-x  root root system_u:object_r:httpd_exec_t   /usr/sbin/httpd

Where in the filesystem is the cgi script located. How did it get 
there.

What is the context of the cgi script

What is the context of the directory the cgi script is in.

What is the context of /tmp. It should be
drwxrwxrwt  root root system_u:object_r:tmp_t  /tmp

The reason I asked that was because how the script got there can 
determine it's context.

For instance:

cp:   gives it the correct context of the directory it was copied into
mv:  does not, it preserves the original context 

But the above context(s) look ok

Ok that's fine.

Now try a little experiment

# touch /tmp/x.x

# ls -alZ /tmp/x.x

should have the following context

-rw-r--r--  root root root:object_r:tmp_t  x.x

You can also try copying and moving a file to /tmp and check the 
context after each to see the difference.
 
Then delete the file created by your script from /tmp and run your cgi 
script by hand.

What is the context of the file now created.

Exactly as I thought. If I touch a file or cp a file into /tmp then it's 
labelled as tmp_t not file_t. On the other hand if I mv a file in it 
retains it's original type. So how could a file created in /tmp get a 
file_t type.

That's why I asked the OP to delete the file and run the script which 
creates the file by hand.

I'm going through the same process as Rob ( the OP ) at the moment. I want to 
setup centos-directory server. initially I want it to replace a NIS and Samba 
system with about 1200 existing users.

Installing centos-ds is not a problem. It's what you do after it. Especially 
for people like me who have no experience with OpenLDAP.

With 1200 existing users to be migrated then GUI based setup and editing is

I'm going through the Howto:Samba from  at the 
moment and hopefully that will get me started.

But what would be nice is:

1. Howto:migtate existing NIS to CentosDS
2. Howto:migrate existing Samba to CentosDS

After reading Carter's book I think i've got some idea of how LDAP works. Just 
a pity that most books/documentation seem to be about OpenLDAP so it takes a 
while to convert to Centos-DS.

I recently had major problems getting Fedora 13 to work on the E6410 ( worked 
fine on the E6510 ;-) )

See the thread "Fedora 13 on Dell E6410 screen resolution problem" on the 
Fedora Mailing list for a discussion and solution to the problem. 

The laptop had a NVidia graphics controller, unlike yours, and the solution 
involved using the propritory NVidia drivers.

It is very easy to install from source, there's even an rpm on the testing

It does compression and pooling of backups.

Yep that's an nfs mount so SELinux type is nfs. At least that's the way it

Well It's live on my local mirror. I've just done a yum update on a test 
server and everything seems OK. So it looks like the wait was worth it.

Good job to all those CentOS developers.

The version of nss you have installed is from the epel repo not base CentOS so 
it is conflicting with something from the 5.3 release. Remove the old version 
of nss, do the update and reinstall nss if required. I had a similar problem 
with one of the NetworkManager rpms from the epel repo.

Thomas,

If you're doing an update from 5.2 to 5.3 you need to have both the base and 
the updates repo enabled. This is because there are some packages that were 
released as updates for 5.2 and they are newer than the packages in the 5.3 
base such as nss. They have been released as updates to 5.3.

Regards,

Tony

Hi,

NFS by default uses random high numbered ports. See "48996  nlockmgr" above. 
You need to tie them down to allow them through your firewall

Create the following file /etc/sysconfig/nfs

#/etc/sysconfig/nfs
# Created 05.07.05 by Tony Molloy

# Number of NFS threads to run
RPCNFSDCOUNT=48

# ports for statd daemon
STATD_PORT=4000
STATD_OUTGOING_PORT=4004

# ports for lockd daemon
LOCKD_TCPPORT=4001
LOCKD_UDPPORT=4001

# ports for mountd daemon
#MOUNTD_NFS_V2=no
#MOUNTD_NFS_V3=no
MOUNTD_PORT=4002

# ports for rquota daemon
#RQUOTAD=no
RQUOTAD_PORT=4003


Then open ports 4000:4004 in you firewall as well as port 111 the portmapper 
and port 2049 for NFS

Hope this helps,

Tony

Put the file on the NFS server and open the ports on the NFS server. Then 
restart NFS services

# service nfs start
# service nfslock start

To make these permanent

# chkconfig --level 35 nfs on
# chkconfig --level 35 nfslock on

Check with rpcinfo that NFS is using the specified ports.

Both are typically installed as part of a CentOS install. But you only need 
one or the other. Generally cron on a 24x7 machine and anacron on a laptop.
One or the otrher is mormally disabled.

cron is a fixed time schedular. I wakes up every minute and checks if there are 
any jobs to be run. It checks /etc'/crontab for system crons to run and also 
in /var/spool/cron for individual crons to be run.

e.g  from my /etc/crontab file

22 4 * * 0 root run-parts /etc/cron.weekly

says

At 22 minutes past 4am run /etc/cron.weekly


anacron is for machines that are not up 24x7 so they could miss some of the 
times when "cron jobs" were to be run. So anacron wakes up and checks the 
/etc/anacrontab file. Then it runs any jobs after a certain delay period ( not 
at a fixed time )

e.g from my /etc/anacrontab file

7   20  cron.weekly nice run-parts /etc/cron.weekly

says

20 minutes after waking up every 7 days run /etc/cron.weekly


Hope this helps,

Tony

It's only on if you have switched it on..
#  chkconfig --list | grep anacron

will tell you if it is switched on

#  chkconfig --level 35 anacon off

will switch it off. on next rebot

#  service anacron stop

will stop it immediatley.

You don't need it on a machine that's up 24x7. cron should handle all your 
scheduled jobs.

By the way I run centos on several of my laptops and they're not up 24x7

You're world may not depend on it but those of us who run 10's of servers need

They're in /var/spool/anacron. Three files cron.daily .weekly .monthly.

That's the date anacron was last run.

Yum probaably updated anacron and set it to running

On my laptop

#  rpm -qa --last | grep anacron
gives
cronie-anacron-1.4.3-4.fc12   Sat Feb 27 11:05:52 2010

So it was updated last on 27th Feb.

Not correct. From ftp.heanet.ie

/pub/centos/5.5/isos/i386>

4185118720 May 11 09:59 CentOS-5.5-i386-bin-DVD.iso
That's 4.1GB

/pub/centos/5.5/isos/x86_64> 

4393723904 May 13 23:37 CentOS-5.5-x86_64-bin-DVD-1of2.iso
That's 4.3 GB

432361472 May 13 23:42 CentOS-5.5-x86_64-bin-DVD-2of2.iso
That's 432Mb

So total is 4.7Gb approx

Maybe you downloaded CentOS-5.5-x86_64-bin-DVD-2of2.iso twice.

As far as I know it contains most of the OpenOffice language packs. It 
shouldn't 
be needed to do an install unless you are going to install some of the more 
unusual packs.

Janez,

I seem to remember having a similar problem with a lab full of those machines 
some years ago. They were running an earlier version of Fedora. What we had to 
do was upgrade the BIOS. They are now running Fedora-11 with BIOS ver 2.6.2

Hope this helps,

Assuming this was a 64bit install the libraries are in /usr/lib64 not

I had similar problems installing 7.2 onto a couple of Dell E6xxx 
laptops with 
Intel Corporation Centrino Ultimate-N 5300/6300 cards. It lets me 
configure the network at install time but when I boot there is no wifi 
device.

Partial solution.

Laptop 1.  ( install when 7.1 was latest release )
installed 7.1no wifi
installed 7.0wifi works
upgraded to 7.1 several months agowifi works
upgraded to 7.2 when it was released   wifi works

Laptop 2   ( install when 7.2 was latest release )
 installed 7.2  no wifi
 installed  7.0 wifi works
 upgraded to 7.2 ( last weekend )   no wifi


Any ideas.

Tony

CentOS 7.0 works when installed but when you upgrade it to 7.2 the wifi 
device stops being recognised.

I'm going to do an install later today of 7.2 and see how it goes.

OK I installed 7.2 ( 7-1511 Development workstation )

Anaconda allowed me to configure the wifi and it got an IP address from 
the router. So the wifi is working.

Reboot and no wireless device recognised.

NetworkManager only offers a wired and network proxy options for 
configuration.

iwl2000/2030 are installed and rfkill says the wireless is neither 
hard nor soft blocked.

So any ideas.

In my case they are both Dell E65xx fairly old but still serviceable.

E6500 has

Network controller: Intel Corporation Ultimate N WiFi Link 5300

E6510 has
Network controller: Intel Corporation Centrino Ultimate-N 6300 
(rev 35)

My workaround.

On the Dell E6500

installed CentOS 7.0 from DVD ( development workstation )
   wifi works

updated to CentOS 7.1 ( 7.1503 ) using vault.centos.org 
   wifi works

updated to CentOS 7.2 ( 7.1511 ) using local repo
   wifi works

So I ended up with a working 7.2.

Hope this helps someone.

Tony.

Anecdotal evidence only so take with a pinch of salt ;-)

I  installed 7.0 on a Dell laptop E6500 wifi worked.

I logged on remotely to do the update to 7.2 ( 7.1511 ) and at the 
same time I was pinging the laptop from another terminal. This should 
give me some idea of when wifi stopped working.

When the wifi stopped working, the pings stopped, in the update window 
the cleanup after the install was taking place and had stopped at 
cleanup of wpa-supplicant. Don't know what significance of that is.

[CentOS] Possible repo polllution

[Tony Molloy]

Hi,

I've just been checking my local copy of the CentOS repos. I found 
200+ i386/i686 packages  in both the updates/5/RPMS and 
updates/6/Packages directories.

I checked with my rsync site ( ftp.heanet.ie )  and the equivalent  UK 
site ( ftp.mirrorservice.org ) and they both carried these packages 
also.

Is this a case a repo pollution, it can't be necessary to have i386 
packages in the x86_64 updates. Just checking before I delete these 
packages.

Thanks.

Thanks Nicolas, John.

These repos are for a bunch of 64 servers, the only one of which 
requires 32bit packages is the one that runs Oracle ;-)

I might as well leave them there, disk space is cheap.

Yep CentOS 5.9 was released on thursday. 100+ package updates 
depending on what you have installed. Upgraded several x64 and i686

Hi,

setenforce 0  sets SELinux to permissive
setenforce 1  sets it to enmforcing
sestatus to check the current status

You can use the following to build a custom SElinux module

#  Generate local policy
grep http  /var/log/audit/audit.log | audit2allow -m myhttp > 
myhttp.te

#  could also use grep  http to just get the http AVC

#  Compile the module
checkmodule -M -m -o local.mod myhttp.te

#  Create the package
semodule_package -o myhttp.pp -m local.mod

#  Load the module into the kernel
semodule -i myhttp.pp

One more problem the OP may have is with ssl.conf. It listens by 
default on port 443 and you can't have both apache instances listening
on that port, the second instance will refuse to start. He'll need to 
change the port for one instance.

Ran into this problem when I tried to run  a separate instance of 
apache for backuppc.

A hack. Set up your resolv.conf as you need it.

Then as root chattr +i  /etc/resolv.conf

Now NM can configure the interfaces but can't change /etc/resolv.conf

I'v been trying to dual boot  windows 7 and CentOS 7 for a week now 
without any luck.

CentOS 5/6 and Fedora 20 recognise the Windows installation and place 
an entry for it on the boot menu.

CentOS 7 anaconda recognises the Windows 7 ntfs partition at 
installation time as unknown but doesn't place an entry for it in the 
grub2 boot files. Did you install CentOS 7 last.

[CentOS] Upgrade to m7.0 retaining some existing partitions

[Tony Molloy]

Hi,

I want to install 7.0 replacing  an existing 6.5 installation.

When I choose custom partitioning I can delete the old 6.5 partitions 
and create new partitions 7.0 but there doesn't appear to be any way 
to retain an existing partition, say /home for instance, over the 
installation.

Am I just missing something obvious or any ideas on what the magic is.

Regards,

Tony

No but I sorted it out myself. I just took a chance, it was on a test 
server anyway ;-)

In the disk partitioning screen you will see the old 6.5 installation. 
Clicking on it will bring up the existing 6.5 partitions. Then select 
each of the existing partitions and a configuration menu comes up which 
allows you to reformat the partition if required. So just don't 
reformat the partitions you want to keep .They then become part of the 
new 7.0 installation.

Hope this helps.

Regards,
Tony

[CentOS] RPM install/upgrade problem

[Tony Molloy]

Hi,

For the last few updates I'm having a yum problem.

# yum update

gives the following error for e.g.

Running transaction
  Updating   : bash-4.2.45-5.el7_0.2.x86_64  1/10
Error unpacking rpm package bash-4.2.45-5.el7_0.2.x86_64
error: unpacking of archive failed on file /usr/bin/alias;5423b9bc: 
cpio: open
 

The same problem happens if I try to use rpm for the update so it 
appears to be an rpm problem rather than a yum one.

I've rebuilt the rpm databases successfully but tthe problem persists.

Regards,

Tony

No, this was a server which had a copy of the centos repos stored 
locally. i actually wiped and redownloaded the updates from three 
separate sources with the same results. It wasn't just bash the latest 
kernel updates were also affected.

Funny thing was late last week it upgraded the bash rpm but failed on 
the bash-doc rpm.

So in the end I just reinstalled the server and everything went fine.

Thanks,

Tony.

I had the same problem. Upgraded to the latest firefox last saturday
everything looked ok all day. Logged in on monday to find my master
password and all my stored passwords were gone. Unfortunately I had
done a backup of the home directories later on saturday. So restoring
the key3.db and logins.json files didn't work.

The problem seems to be with the key3.db file. When the latest firefox
(re)creates it, it has the wrong permissions

-rw---.  1 molloyt molloyt1137 Oct  3 16:09 logins.json
-rw---.  1 molloyt molloyt   16384 Oct  3 14:48 key3.db


I removed firefox, deleted the .mozilla directory and reinstalled
firefox. But the problem remains.

1. Delete the logins.json and key3.db files
2. Start firefox key3.db file created with the above permissions and
   selinux context looks ok
3. Set master password and a few account passwords
4. Check they're there in preferences, ok
   logins.json file created with above permissions
5. login/out a few times to the accounts to make sure everything
   works,ok
6. Shutdown firefox and restart it, account settings ok and working
   but key3.db file gone
7. Shutdown firefox and restart it, master password and accounts gone
   check recreated key3.db file and it has permissions as above.

I'm stumped.
Any ideas gratefully accepted ;-)

Hi Akemi,

That sorted the problem for me, thanks.
Now to start re-entering all my previously stored passwords. Lucky I
have a list of sites if not the usernames/passwords ;-(

Put it in your .bash_profile. Then it will be set in your environment
each time you boot.

The problem is that the current version of Mate in the EPEL repos
prevents updating from 7.5 to 7.6. There is a dependency problem with
libgtop.

For example trying to update marco gives you.

Resolving Dependencies
--> Running transaction check
---> Package marco.x86_64 0:1.16.1-3.el7 will be installed
--> Processing Dependency: libgtop-2.0.so.10()(64bit) for package:
marco-1.16.1-3.el7.x86_64
--> Finished Dependency Resolution
Error: Package: marco-1.16.1-3.el7.x86_64 (epel)
   Requires: libgtop-2.0.so.10()(64bit)
 You could try using --skip-broken to work around the problem

The same dependency holds for several mate packages.

So either hold back on the update until mate is updated or build it
yourself are the choices..

Regards,

Tony.

Yep I'm just running up a VM to test the epel-testing solution.

I see you got no replies to your question so here goes.

I've got CentOS 7 running on a Dell Precision 7510 workstation. It has NVidia 
graphics 
but I've never had problems with Intel graphics on any CentOS box before. The 
install was 
straight forward and it runs like a dream. 

YMMV ;-)

[CentOS] Possible Font problem with CentOS 7

[Tony Molloy]

Hi,

I've got a possible font problem with a fully updated CentOS 7 system.

An example with the man command.

#man kill

Should return the following

KILL(1) User Commands   KILL(1)

NAME
   kill - terminate a process

SYNOPSIS
   kill [-s signal|-p] [-q sigval] [-a] [--] pid...
   kill -l [signal]


but what I actually get is the following

KILL(1)   User CommandsKILL(1)


   kill - terminate a process


[ signal| ] [ sigval] [ ] [ ] pid...
[signal]

Notice the missing text.

If I select the text and paste it into an editor I see the missing
text. So it's there just not displaying on the screen.

I also notice the effect with links embedded in e-mails. I use
evolution. Embedded links do not appear in the e-mail but if I hover
over a link location then it appears in the text box at the bottom of
the page and I can select it.

I suspect I'm missing some common font(s).

Any ideas.

Regards,

Tony

Thanks, that sorted the terminal problem. Now for the e-mail problem.

I got the solution for the terminal problem. It was a setting in the
terminal preferences settings which I had unticked. So now for the
e-mail problem. This I assume is also a preferences problem with either
my theme selection or with evoloution itself.

Thanks for the reply,

You can install MATE for CentOS 8 from the stenstorp repo

https://copr.fedorainfracloud.org/coprs/stenstorp/MATE/


I've been using it for some time with no problems.

Oh you were looking for mate-1.20 for CentOS 7. Sorry for the noise,
should read the e-mail before replying ;-(
