[CentOS] DHCP/DNS server for LAN with mainly Windows clients : Outlook Express vs. Webmail problem
Hi,
I recently setup a CentOS 5 file server for a small LAN consisting of 15
Windows XP clients. The LAN is eventually expected to migrate to Linux,
at least some of the client machines.
The previous setup made by a local Windows-only computer firm was an
unhealthy mix of static and dynamic IP addresses with conflicting
adresses, etc. First thing I undertook was clean up this mess by setting
up a DHCP + local cache DNS server on the Linux machine.
Now the curious problem I have: IP addresses are attributed correctly,
people can surf on the internet all right. But the only thing they can't
seem to do is send mail with Outlook or Outlook Express. I have to
revert to the ISP's DNS, but so I lose the benefit of local DNS. And I
don't have the slightest clue as to why that is so.
Here's my setup, maybe one of the gurus on the list has an idea:
1) /etc/dhcpd.conf (the fixed addresses are attributed because the local
printer has a page counting device that works with IP adresses):
--8<---
ddns-update-style interim;
authoritative;
default-lease-time 86400;
max-lease-time 86400;
option broadcast-address 192.168.0.255;
option subnet-mask 255.255.255.0;
option routers 192.168.0.1;
option domain-name-servers 192.168.0.2;
option domain-name "regards.arles";
subnet 192.168.0.0 netmask 255.255.255.0 {
range 192.168.0.100 192.168.0.150;
}
host poste1 {
hardware ethernet 00:26:18:B7:D6:10;
fixed-address 192.168.0.101;
option host-name "poste1";
}
host poste2 {
hardware ethernet 00:24:81:69:A3:DE;
fixed-address 192.168.0.102;
option host-name "poste2";
}
host poste3 {
hardware ethernet 00:1B:FC:6F:66:2C;
fixed-address 192.168.0.103;
option host-name "poste3";
}
...
--8<---
For setting up Bind, I used a "dummy" domain name, like I usually do in
LAN's. For example, my home network is "presbytere.montpezat", the local
town hall's network is "mairie.montpezat". The network here is
"regards.arles". ("Regards" is the name of a local association, and
"Arles" is the city in South France where it's located).
2) /etc/named.conf:
--8<---
options {
directory "/var/named";
listen-on { 127.0.0.1; 192.168.0.0/24; };
};
zone "." IN {
type hint;
file "named.root";
};
zone "localhost" IN {
type master;
file "zone.localhost";
allow-update { none; };
};
zone "0.0.127.in-addr.arpa" IN {
type master;
file "revp.127.0.0";
allow-update { none; };
};
zone "regards.arles" IN {
type master;
file "zone.arles.regards";
};
zone "0.168.192.in-addr.arpa" {
type master;
file "revp.192.168.0";
};
--8<---
3) /var/named/named.root:

[CentOS] Service monitoring/"Monit"?
Has anybody here tried the "Monit" utility (http://mmonit.com/monit/)? I need to set up some kind of "watchdog" functionality for a custom service otherwise started via init (i.e. via a script in /etc/init.d + rc*.d links managed by chkconfig) and it seems like this system may give me nearly what I want. However, something that concerns me about it, is that it appears to take full ownership of the services it monitors, and pretty much bypass the init system, in that once I've told monit to watch a process, it makes not difference if the associated service is enabled or not (via "chkconfig") , and there is no good way to fully stop the service, besides removing the Monit config or disabling Monit itself. (Or maybe I can use special "monit" commands, too, but that means precisely that Monit "owns" the service, which I somehow don't quite like.) What I'd really like, is to have my process watched and restarted if it goes a way, but only if it had already been started via "init" or through the "service" command, or possibly direct execution of the "init.d" script. This also means it should be restarted if it crashes or if is stopped via a direct "kill", but not after "service stop" or similar. Which might mean it all boils down to checking if, and only if, the pid file for the service already exists. (Does that make any sense?) So, does anyone know if there is a way to convince Monit to do this for me? Or alternatively, is there a different tool that might do the job? And yes, I know it shouldn't be that hard to design a program/script/cron job to do it all for me, but I still think not having to maintain another software component would be nice... - Toralf This e-mail, including any attachments and response string, may contain proprietary information which is confidential and may be legally privileged.

Try this: 1. put to /etc/monit.conf this line: include /etc/monit.d/*.conf 2. for active services make you own files in /etc/monit.d, ex. /etc/monit.d/sshd.conf: # ssh control check process sshd with pidfile /var/run/sshd.pid start program "/etc/init.d/sshd start" stop program "/etc/init.d/sshd stop" if 5 restarts within 5 cycles then timeout 3. when you change service to chkconfig sshd off rename /etc/monit.d/sshd.conf to something different: mv /etc/monit.d/sshd.conf /etc/monit.d/sshd.conf-dontuse Pavel ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Depending on how much effort you are willing to put into this, you can get nagios to do this. There are two options: 1) Create a custom plugin that checks "service [app] status" or directly check the pid file and pgrep/grep for the app. 2) Write a small script that you stick into the service init script that tells nagios to start or stop monitoring a service. I used perl and LWP to do something very similar but you can probably find another CPAN module or something similar to act as interface to nagios. If you are comfortable with scripting and nagios you can bang out a solution in an afternoon. Option 1 you can probably do in less than an hour and is probably better for you. - Geoff Galitz Blankenheim NRW, Germany http://www.galitz.org/ http://german-way.com/blog/ ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

There is also a "dependency" mechanism that would do this, if only it implemented real, hard dependencies.

[CentOS] MooseFS repository
Hi, A repository for MooseFS is just born. It provides CentOS 5.5 SRPMS, i386 and x86_64. cd /etc/yum.repos.d/; wget http://centos.kodros.fr/moosefs.repo ; yum install mfs Two points: - DNS may not be up to date where you are. The subdomain has just been created. Please be patient. - I have made an update to the .spec file, to move config files to /etc/mfs instead of /etc. I had no time to test it yet. I guess it works :) What is MooseFS ? MooseFS is a fault tolerant, network distributed file system. It spreads data over several physical servers which are visible to the user as one resource. For standard file operations MooseFS acts as other Unix-alike file systems: * A hierarchical structure (directory tree) * Stores POSIX file attributes (permissions, last access and modification times) * Supports special files (block and character devices, pipes and sockets) * Symbolic links (file names pointing to target files, not necessarily on MooseFS) and hard links (different names of files which refer to the same data on MooseFS) * Access to the file system can be limited based on IP address and/or password Distinctive features of MooseFS are: * High reliability (several copies of the data can be stored across separate computers) * Capacity is dynamically expandable by attaching new computers/disks * Deleted files are retained for a configurable period of time (a file system level "trash bin") * Coherent snapshots of files, even while the file is being written/accessed For more details, see http://www.moosefs.org Feedback welcome !

God and Bluepill can both do these things. Its a classic case of what I call reactive-monitoring. So you only look at specific conditions - then wrap them around a policy each. The problem with monit is that its unable to handle more than one condition in one run cycle, and its extremely hard to do co-ordinated scheduling across tasks using the monit config files.

OK.
From reading the docs on the web sites, there are a number of things
that are not quite clear, like what the "process" tests actually do, or
how I might combine a file test ("does the pid file xist"?) with them (f
that's what I want. This is perhaps partly because I don't speak Ruby,
and I'm sure what I want is doable...
Do you happen to know if any of these tools are available from yum
repositories and/or in rpm package form?

Definitely. But do my mind, "service A depends on service B" should mean
that if service B isn't active, and can't be started, then there will be
no attempt to start service B, either - and there might even be an
attempt to stop it if it's already running. Not so with Monit, like I
said...

Ok, that might be a bit of an issue for you - but basically, you get an
object that you can do any sort of tests on. eg
restart.condition(:memory_usage) do |mu|
mu.above = 1024.megabytes
mu.times = [ 5,7 ]
end
Which will restart the process if 5 of the last 7 checks indicated it
was using more than 1G of ram. Its basically just ruby and coding around
it, so you can define what the logic or smartness you want around the
monitoring and just code it in.

Not that I am aware of, I've been using them from an internal repo we
have here at work, but thats heavily optimised to our own specific
requirements ( eg. running on ruby 191 etc ). There is a gem2spec app
that will hapily convert a ruby gem into a rpm spec file.

This is where the flexibility of God comes into play, you can write any
sort of logic around the conditionals.

I see 4 ways:
echo jj_${VERSION}_jj
echo jj_"$VERSION"_jj
echo jj-$VERSION-jj | tr '-' '_'
printf jj_%s_jj $VERSION
I am sure there are others.

I am currently playing with a 64 bit machine. I can set my upload_max_filesize = 2G and that works fine; however, post_max_size is a problem. if I set it to 2 G it seems to fail (no POST transactions go through, it seems). If I set it just a tad lower (what I have now is post_max_size = 1948M ) it works fine. So the cutoff limit is somewhere in the 2G neighborhood. Any idea why that would be? Is there a parameter anywhere that limits how far post_max_size may go? The total memory setting I use is way above ( memory_limit = 6G ) and that seems not to cause any issues.

I'm going to kick this old thread because I'm just getting around to nfdump and nfsen myself, and am having trouble building nfsen. I do not see a mailing list for it so I'll try here first. I am using softflowd to pump netflow information from various linux boxes into a central collector. The collector is running nfcapd to capture everything. And I also want to run nfsen on this box to be able to view the pretty graphs on the web :-) I have verified with nfdump built on this box that the collector seems to be working fine - so far so good. Then when trying to build nfsen it complained about nfprofile not being there - so some googling later and I found that I have to go back and rebuild nfdump to include it. So I do : ./configure --enable-nfprofile which dies thus : [...] checking for stdint.h... yes checking for unistd.h... yes checking for rrd_update in -lrrd... no configure: error: Can not link librrd.

Parenthesis didn't work for me... Braces and escape work. I gave the
escape example, but I think the braces solution is the pedantically most

This was for raid 1 drives, not sure how raid 0 would do on it... These were my notes for adding a hotspare that would auto take over on a failure, 3 drives total..this covers adding drives back to the array and also adding a brand new one. I did not cover a 2nd hot spare...again this was just raid 1... Adding a drive back into the mix if you pulled it out via hot swap So, you pulled a drive out to check the hot swap. Guess what, it is not recognized by the array anymore and is ignored. This is a good way to check if the hotspare is working. But now what do you do with the drive you put back in? Each drive is labeled sda, sdb, sdc on my system. There are two raid devices on the array, one a boot and one the big physical one. on mine they are labeled as md0 and md1 (0 and 1). So when we are working on a raid on a drive we would say sbc2 (second raid device on 'c'..sbc drive). Assuming the sda drive is our functioning one, and I took out both b and c drives, we will add b and c back in the mix. mdadm /dev/md0 -add /dev/sdb1 mdadm /dev/md1 -add /dev/sdb2 The sdb drive should immediately start its migration. Should take about an hour depending on your system. Now add the spare back in., sbc. mdadm /dev/md0 -add /dev/sdc1 mdadm /dev/md1 -add /dev/sdc2 Doing ' cat /proc/mdstat ' will show you all three drives are there, one with the (S) for spare and the other in the middle of migrating. Now you have your RAID array set up, have LVM partitions you can adjust later as you need them, can recover from pulled out disks, and all disks are now bootable. Congratulations, you are done with the whole disk thing. Final Issue. Adding a new drive into the mix to replace broken one So, you pulled a drive out because it was broken and need to replace it. You also want it to be part of the mirror array and need to copy the partitions of the existing one to it before you add it to the array. Sounds frightening. 1- take out old drive and make sure the other two are mirroring, the new drive you will add will be the hotspare now. (this is called rotation by the way) 2- Insert new drive. 3- in the command prompt, type fdisk -l (that is an L). This should give you a list of drives and partitions. The new disk should be there too with one partition or none. This will give you the 'drive designation' if you do not know it. 4- CAUTION Make sure before you do number 5 that you now which drive is the new one sda, sdb, or sdc 5- type " sfdisk -d /dev/sda | sfdisk /dev/sdb " This is supposed to copy the partition table from disk a to disk b (insert your actual drives for a and b inthe example). 6- use fdisk -l to see if the new drive has all the proper partitions. 7- if everything is fine, use the above method via mdadm to add the new 'spare' into the array. It should automatically make it the spare drive. Using the new drive for the spare ensures the older drives are used as much as possible until you replace them and your back ups will be tip top and not a very old drive. Rotation works like tires for your car. Would you like your spare tire to be a brand new radial ready to go 60,000 miles or a retreaded old worn tire ready to get you to the gas station to replace it? I would feel better having the new tire so I do not have to worry when I use it. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Is there another place I should be looking? Couple of things - Most of CentOS-5 is /5/ - the .2 and .5 only point at snapshots in time for the distro. Also, upstream have not updated most of the docs past 5.2 anyway. Most of the docs that you can see online are included in the distro as the guides, so you should be able to install and use them locally. - KB ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] 5.5 & gspca
Irritating quirkyness: we have a bunch of videocams. To use, we use gspca.
Usually, on an upgrade, I just go into the gspca directory (which appears,
from their website, to have not been updated since '07), make clean, make,
make install.
Having gone up to 5.5, did the same. What's happening now is that it
works, delivers the mpgs... but dumps errors in the logs:
kernel: /usr/local/src/gspcav1-20071224/gspca_core.c:
[spca50x_move_data:1611] ISOC data error: [0] len=0, status=-18
Looking at the code, I see
static int
spca50x_move_data(struct usb_spca50x *spca50x, struct urb *urb)
{
unsigned char *cdata; //Pointer to buffer where we do store next
packet
unsigned char *pData; //Pointer to buffer where we do store next
packet
int i;
for (i = 0; i < urb->number_of_packets; i++) {
int datalength = urb->iso_frame_desc[i].actual_length;
int st = urb->iso_frame_desc[i].status;
unsigned long ms_times_now;
unsigned long ms_times_before;
struct spca50x_frame *frame;//Pointer to frame data
int sequenceNumber;
int sof;
int iPix; //Offset of pixel data in the ISO packet
if (st) {
PDEBUG(0, "ISOC data error: [%d] len=%d, status=%d
\n",
i, datalength, st);
continue;
}
cdata = ((unsigned char *) urb->transfer_buffer) +
so the first number is the packet #, which I see 0 through 3 or 5 in my
logs. The error, which is the status, *if* errno.h has any relation, says
that it's an EXDEV, which suggests that it's trying to hard link across
devices, which AFAIK it's not: the home directory for the user the device
runs is is automounted, and it gets created there.
Anyone have any clues why, all of a sudden, the first few packets are
showing a status code? Could it be a timing issue?

Well I find these things interesting. Could very well be timing in the
frame buffers/packets. I'm guessing this is the newest latest kernel.
I've seen somewhere this week somewhere on the web about a related
issue.
So guessing it works correctly on the previous kernel? Just something
to ponder here is the machine really loaded heavily? I ask because if
so the kernel can't function on "us" microsecond timing. It becomes
very critical when it comes to that nature.
Last thing is the timing routine function getting called in userspace or
kernel? I have had my share of day to day problems like this. Last
thing was anything in /etc/sysctl.conf changed? Finally whats nice is,
it could have been coded to skip a frame sequence where the before and
after timing did not match and you eye would never see it..

Right - my manager actually encouraged me to look at the code, and I was trying to recompile after putting a sleep(1) before any of the streaming is called, but I'm having all kinds of grief, since it can't find , and when I put it in as #include "/usr/include/unistd.h", it spits out a ton of undefineds, and unuseds, etc. > > Last thing is the timing routine function getting called in userspace or > kernel?

You can fill a buffer and reassemble the frames/packets in there order cpu intensive dearly it is. Your better to skip the frames because the human eye can never see it. Believe it or not medical imaging takes on this method and lives get saved every day from tomography/mri/cat/ultra sound scans in real time.

No idea the version that was compiled or against what just found it. http://atrpms.net/dist/el5/gspca/ You know 2007 is a good while ago and there are many compiler changes in between the time. I say it may be something getting introduced from the current compiler methods that is not supported now.
