Bind chroot via the standard chroot package should just with with selinux...

Be careful that you don't just follow the audit.log blindly (eg audit2allow
-aM) but think through each but carefully...

I'd suggest starting for each exception with "is this already covered by a
boolean" and then double checking your file contexts before even
considering an additional custom module.

Hi larry,


I think your method is the easiest way.

I currently have below cronjob that sends the output to /tmp/backup.out
file. it is OK.

35 13 * * * root /root/scripts/backup.sh > /tmp/backup.out 2>&1

How can I then send this /tmp/backup.out to an email address.


Here's the one I created

[root@host ~]# ls -al /root/send_email.py
-rwxr-xr-x. 1 root root 382 2013-07-23 15:18 /root/send_email.py


[root@host ~]# cat /root/send_email.py
#!/usr/bin/python

import smtplib
from email.MIMEMultipart import MIMEMultipart
from email.MIMEText import MIMEText

from_addr = 'r...@host.example.com'
to_addrs = ['myem...@gmail.com']
msg = open('/tmp/backup.out','r').read()

server = smtplib.SMTP('192.168.9.5', 25)
server.sendmail("r...@host.example.com", "myem...@gmail.com", msg)
#server.sendmail(from_addr, to_addrs, msg)


Should I APPEND the PATH of the script (/root/send_email.py) to
/root/scripts/backup.sh file. ?


I just ran this script (i.e - /root/send_email.py). It worked. I got the
email. But no subject there.  How can I add a subject called " CRON JOB
OUTPUT " to the email receive .

Hope to hear from you.

For some reason SELinux was blocking the updates to the zone files that 
are the result of DHCP leases being issued. Fixed now. Also I run 
MailScanner and the SELinux context needed corrected on mqueue.in, in 
addition to allowing SSH to operate on the non-standard port I've set it 
to.

Thanks

[CentOS] How often is kernel "touching" swap partition?

2013-07-23 Thread Martin Šťastný
Hello,

I am going to buy new laptop with two drives, one SSD and one HDD and I
want to place swap partition on HDD which will be most time unused and
therefore spinned down. Problem is, that I don't know, if or how often is
kernel touching swap space even if there is lot of free memory and thus
spinning HDD up.

Thank you in advance

You should partition your drives anyway: a small, like 1G, partition for
/boot. For swap, the old Received Wisdom was 2-2.5 times RAM; these days,
it's "make swap to be 2G (for emergencies). Put swap on the SSD, I
*guess*... if it's enterprise grade, and not "consumer grade", which will
eventually give up with too many writes.

There's a kernel tunable called "swappiness" [1] to control that.  You
can add an entry in /etc/sysctl.conf like this:

vm.swappiness=0

...and the kernel will avoid, as much as it can, to use swap.

Re: [CentOS] How often is kernel "touching" swap partition?

2013-07-23 Thread Martin Šťastný
Thank you for you responses,

first of all I need same amount of swap space as of memory, because I want
to use hibernation. Problem of placing swap partition on SSD is not with
too many writes, but with to much space used for nothing (in my case 8 GB,
16 GB in not so far future). I know about "swappiness" kernel tunable, but
I guess it has nothing to do with how often is partition "simply touched
for nothing" and therefore hard drive is spinned up. For example - if I set
HDD to spin down after two minutes and kernel will touch swap approximately
every five minutes, it means that hard drive will be spinned up 120 times
every day (10 hours of power on), 43 800 cycles per year which will
definitely wreck my HDD :-(.

It almost certainly isn't easier than installing ssmtp.  Everything that 
you'd have to to to get ssmtp to work you will also need to do to that 
python code, plus you have to manually send email for every job where 
you need it.

You're going to have to create your own RFC compliant headers.  See how 
that's already more complicated than using ssmtp?  (Cron already does 
that work if you install an MTA, such as ssmtp)

Re: [CentOS] How often is kernel "touching" swap partition?

2013-07-23 Thread wolfy
You know that you don't need a swap partition for hibernation?
s2disk(uswsusp) makes a swapfile on your hdd prior to hibernating and 
only activates it for hibernation purposes, so you don't have to have 
swap active all the time.

[CentOS] What on Centos is wiping out my eth0 IP address every 5 minutes?

2013-07-23 Thread Rock
QUESTION:
Why does my Centos 6.4 laptop keep wiping out my eth0 IP address?

SUMMARY:
a) I set the IP address of eth0
b) Everything works fine for 2 to 5 minutes
c) Then, that eth0 IP address is (somehow?) wiped out
I frustratingly repeat that abc process (over and over and over again)

BACKGROUND:
My home network has been working perfectly and there is no problem 
with my home network, nor my wlan0 WiFi access from my Centos 
laptop to that home broadband network.

Inside the house, I never use the wired (eth0) NIC; but, I'm trying
to set up a wired/wireless connection outside the house and that is 
where I'm running into this problem where Centos (automatically?)
constantly and repeatedly wipes out the IP address I set on eth0. 

I can easily (constantly) change the IP address of the eth0 NIC back
to what I want it to be; but that IP address only stays set for 
about 2 to 5 minutes; and then it wipes itself out (again & again).

Why? How do I stop this?
(All I want is for eth0 to *stay* at the IP address I set it to!)

To give you more contextual detail, here's a typical sequence.

SIMPLE BASELINE:
 Wireless NIC (wlan0) is turned off using a hardware switch on the 
 outside of the laptop (so that only one NIC is in play).

STARTING POINT: (eth0 has no IP address)
$ ifconfig eth0
=> eth0 Link encap:Ethernet  HWaddr A0:BE:C1:D8:E5:F1  
=>   inet6 addr: fe80::f2de:f1ff:fe38:8591/64 Scope:Link 
=>   UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
=>   RX packets:3139 errors:0 dropped:0 overruns:0 frame:0
=>   TX packets:3230 errors:0 dropped:0 overruns:0 carrier:0
=>   collisions:0 txqueuelen:1000 
=>   RX bytes:2403080 (2.2 MiB)  TX bytes:547895 (535.0 KiB)
=>   Interrupt:20 Memory:f260-f262 

I EASILY CAN SET THE IP ADDRESS of eth0:
$ sudo ifconfig eth0 192.168.1.100
$ ifconfig eth0
=> eth0   Link encap:Ethernet  HWaddr A0:BE:C1:D8:E5:F1  
=>inet addr:192.168.1.100  Bcast:192.168.1.255  Mask:255.255.255.0
=>inet6 addr: fe80::f2de:f1ff:fe38:8591/64 Scope:Link
=>UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
=>etc.

At this point, I can now connect a wire from the RJ45 port of the laptop, 
to the device (which happens to be a radio set to 192.168.1.20):

$ ping 192.168.1.20
=> PING 192.168.1.20 (192.168.1.20) 56(84) bytes of data.
=> 64 bytes from 192.168.1.20: icmp_seq=1 ttl=64 time=1.38 ms
=> 64 bytes from 192.168.1.20: icmp_seq=2 ttl=64 time=0.339 ms
=> 64 bytes from 192.168.1.20: icmp_seq=3 ttl=64 time=0.255 ms
^C
=> --- 192.168.1.20 ping statistics ---
=> 3 packets transmitted, 3 received, 0% packet loss, time 2954ms
=> rtt min/avg/max/mdev = 0.255/0.660/1.388/0.516 ms

I can even easily connect via port 80 (using Firefox on the laptop)
to this device, e.g., 
$ firefox http://192.168.1.20 

In fact, time and time (and time) again, everything works just fine, 
for about 2 to 5 minutes, until, invariably, I lose all connectivity!

What seems to happen is that CentOS wipes out my IP address that I 
had set for eth0. So, I lose all connectivity.

$ ifconfig eth0
=> eth0Link encap:Ethernet  HWaddr A0:BE:C1:D8:E5:F1  
=> inet6 addr: fe80::f2de:f1ff:fe38:8591/64 Scope:Link
=> UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

I can repeat the process, and everything works again, for about 2 to
5 minutes. Then I lose my eth0 IP address again. 

WHAT I WANT:
When I set eth0 to an IP address, I want eth0 to *stay* at that IP address!

My question:
Q: Why does setting an eth0 IP address only last about 5 minutes on Centos?
What am I doing wrong?
What can I do to *keep* the IP address on eth0 that I set for eth0?

the interface is probably configured for DHCP via 
/etc/sysconfig/network-scripts/ifcfg-eth0  and your system is 
undoubtedly running network-manager.

I don't know *how* to tell if I'm running network-manager, but, 
I'm running whatever everyone else runs on Centos since the 
home broadband network has been working for a year or more with
this laptop without problems.

When I set the laptop back to normal (on the home wireless network), 
here is what shows up when I right click on the network icon: 
 http://i43.tinypic.com/11h7ynk.png

Interestingly, that ifcfg-eth0 file doesn't exist in:
$ ls /etc/sysconfig/network-scripts/ifcfg-eth0

=> ifdown-ippp   ifup-aliases   ifup-ppp
=> ifdown-ipv6   ifup-bnep  ifup-routes

But, that file does apparently exist elsewhere:
$ sudo updatedb; locate ifcfg-eth0
=> /etc/sysconfig/networking/devices/ifcfg-eth0
=> /etc/sysconfig/networking/profiles/default/ifcfg-eth0

$ cat /etc/sysconfig/networking/devices/ifcfg-eth0

there ya go!(NM == NetworkManager)

as root,

 service NetworkManager status

will undoubtedly say its running (and its not something you want to stop 
as its required for wifi and such).

so, set the above line to ="no"  and you can manually configure that port.

or, use the Network Manager GUI to configure it.

you'd be better off configuring your eth0 via Network Manager's GUI. 
mixing manual editing of config files and the GUI is messy.

Am I correct in "assuming" the file to change is this one?
 /etc/sysconfig/networking/devices/ifcfg-eth0

And not this one?
 /etc/sysconfig/networking/profiles/default/ifcfg-eth0

I didn't want to complicate things, but whenever I use the GUI from right
clicking on the four bars, the same thing happens (eth0 disconnects after

That reference doesn't say much about what to set the gateway to:
 http://i41.tinypic.com/1z2n6uv.jpg

Reading section 8.3.9.4 "Configuring IPv4 Settings":
https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Deployment_Guide/sec-Configuring_Connection_Settings.html

All it says about the "Gateway" is:
  Gateway — The IP address of the gateway leading to the network, sub-net or 
host. 

In my situation, I'm connecting a CAT5 cable from the RJ45 eth0 port of the 
laptop
to a radio, which is a router, which is, by default, set up to *not* hand out 
DHCP addresses (Ubiquiti Nanobridge M2) and which is set up, by default, on IP 
address 192.168.1.20.

Given that information, do you have any idea what I should set the gateway to 
in the suggested forms? (they won't let me leave the gateway blank)

odd, the RHEL6 docs say that file should be in 
/etc/sysconfig/network-scripts and that the files in 
/etc/sysconfig/networking/devices shouldn't be messed with

https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Deployment_Guide/s1-networkscripts-interfaces.html
etc etc (these are all links off that first page, or each other)

on that 3rd link, note the last thing on the page about 
/etc/sysconfig/networking/... being deprecated.

hmm, when you configured it with the GUI, did you set that eth0 
connection to 'Manual' ?


btw re your other question about gateway, there should be ONE global 
default route to the internet regardless of the interface.

Maybe I was editing it wrongly.

How does this look?
 http://i43.tinypic.com/n3lsnk.png

The question is what to make the "gateway" since the GUI insists on having
a gateway.

In my case, I'm plugging in a Ubiquiti Nanobridge M2 radio/router, which 
is configured, by default, on 192.168.1.20. 

So, I set the eth0 of the laptop to anything on that same subnet, e.g., 
192.168.1.100; but I don't know what to set the Network Manager "gateway"
to.

Q: Should I set the NM gateway to the IP address of the radio/router?

Note: The desired connection is:

a) Laptop sitting 300 feet from the house 
b) It's ok if the wireless wlan0 NIC is manually turned off 
c) The wired eth0 NIC is set to the subnet of the radio (e.g., 192.168.1.100)
d) I don't know *what* to set the eth0 gateway to (192.168.1.20?)

Then, a CAT5 cable is connected from the laptop RJ45 eth0 port to 
the one and only RJ45 port on the Ubiquiti Nanobridge M2 radio.

At that point, I would ping the radio (at 192.168.1.20) over that eth0 wire, 
and then connect over that same eth0 wire with Firefox to http://192.168.1.20 
(the default login = ubnt, and the default password = ubnt). 

Once logged into the radio GUI, I can set it up to connect to my home 
broadband router access point (or to a local Starbucks five miles down 
the road, for that matter).

QUESTION:
Given that the Network Manager is insisting on me giving it a "gateway", 
what would you suggest I set the "gateway" to in the Network Manager?

Note: I realize this may no longer be a Centos question...

The gateway would be the address of the device on  your network that 
knows how to route packets outward. In my case, where we have some
wired systems and some wireless, both managed by a home router at
192.168.2.1, the gateway for all systems is 192.168.2.1, since that
system knows how to send packets outward, as necessary.

your network sounds as if it may be slightly more complicated, so I'm
not sure I can advise you, as my mental picture of your network is a bit
fuzzy.

Yes. 192.168.1.20 should be fine if you're only using these settings to 
get the nanobridge configured.

But why not just see what IP, Gateway and DNS Servers your home router 
gives eth0 via DHCP and duplicate those settings statically? (presuming 
it's also the 192.168.1.x /24 network)... most home routers can be 
configured to reserve the same IP address for a particular MAC address 
(makes port forwarding via a DDNS account a lot easier), so those static 
settings wouldn't mess up your network if you didn't set eth0 back to DHCP.

I only partially understand what I *think* you're trying to tell me as I
am clearly not a network guru.

I *think* you're saying I should first plug the laptop, by cat5 cable from
eth0 of the laptop to the home broadband router, and then write down whatever
IP address I get, the gateway, and the DNS Server thru it's DHCP assignments. 
[Note: I already have a WinXP PC attached to that home broadband router, so, 
maybe I can get that information from it?]

Then, I think you're saying I should take the CentOS laptop, instead of using
the puny wireless NIC inside it, I should use the eth0 NIC connected to the 
23 dBm radio and its 18 dBi antenna, so that the laptop essentially has 41 
decibels of WiFi beamed at the house open guest access point, 300 feet away.

Is that right?

Hi.
I have a test system in an lab I have copied over  the /etc/sysconfig/nfs
and /etc/exports from productions all the same services are running. But in
the test environment the client mounts the nfs exports but the file system

We are using nfs v3 and it's configured on the server and in the mounts on

Yes.
You might also be able to set the home broadband router to give the 
laptop's eth0 the same IP address every time it sees eth0's MAC address 
ask for an IP.  What brand/model is the home broadband router, by the way?

Well, you could... but all you'll get from that is the gateway and DNS 
settings. Note that setting the Gateway to match isn't necessarily going 
to make it use that gateway if there's no path to it (the nano would 
have to be connected to the home router to pass that traffic along)... 
you were asking what to put in that field so you could save the 
settings, and using an actual gateway IP is better than just picking a 
random IP in the network, in my opinion.

Well, that would result in an EIRP of almost 13W, or about 30 times the 
legal limit for licensed HAMs on channel 6 and below in the 2.4GHz band, 
or 60 times the legal limit unlicensed, unless you use a highly 
directional antenna. But that also assumes you're in FCC land (I don't 
know for a fact there aren't Starbucks worldwide :).

I inferred you wanted to make the laptop talk to the ubiquiti nano through the 
RJ45 port in order to configure it. If I misunderstood the intent, I apologize.

Otherwise, you didn't really tell us any plans for it besides connecting 
to the Wayport Access network at Starbucks 5 miles away... which likely 
won't work without lengthening the Ack wait times - *at both ends* - for 
what that info's worth; most units will wait only long enough for the 
signal to travel between 400 and 1000 yards before giving up and 
resending the packets... (assuming they're even able to exchange enough 
packets to actually negotiate and establish a connection). That's one 
reason why "more power" is rarely the solution to wireless problems.

Netgear N600. I bought it in a moment of weakness; but it's far
too anemic to make it outside by the BBQ where I want to set up
the computer.

So, my goal is to connect the Nanobridge M2 to my laptop when I'm 
at the BBQ, and to beam that Nanobridge M2 at the house, to pick
up the Netgear N600 open "guest" SSID access point.

Does that sound workable?

I'm in the USA.

The Ubiquiti Nanobridge M2 is a legally bought and sold radio in the US.
I can't imagine that using it would be illegal from a power standpoint.

Maybe I got the numbers wrong? 
 http://site.microcom.us/nbm2_datasheet

Shouldn't that Nanobridge m2 be powerful enough to reach the 300 feet 
or so to go from my BBQ to my home broadband router open "guest" 
access point?

Well, that is a necessary evil, so, yes, that is the first step, 
to configure it.

But, I'll take up that configuration elsewhere, as that's not a
CentOS issue per se. 

Right now, I only want to know what to set the gateway to, as that
is somewhat of a CentOS issue (regarding how it's set anyway).

When my Centos laptop (192.168.1.3) is connected wirelessly to my 
home network (192.168.1.x), on wlan0, the following is seen on Centos:
$ ifconfig wlan0
=> wlan0 Link encap:Ethernet HWaddr 0A:2B:DC:7D:8E:AF
=> inet addr:192.168.1.3 Bcast:192.168.1.255 Mask:255.255.255.0
=> etc.

The gateway is apparently set to the home broadband router IP 
address (192.168.1.1):
$ route -n
=> Kernel IP routing table
=> Destination Gateway Genmask Flags Metric Ref Use Iface
=> 192.168.1.0 0.0.0.0 255.255.255.0 U 2 0 0 wlan0
=> 0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 wlan0
Where the gateway is 192.168.1.1 and it's up (U) and it's a gateway (G).

This command confirms the current gateway, when acting through wlan0, 
is 192.168.1.1 (which is the Netgear N600 broadband router):
$ route (or netstat -r):
=> Kernel IP routing table
=> Destination Gateway Genmask Flags Metric Ref Use Iface
=> 192.168.1.0 * 255.255.255.0 U 2 0 0 wlan0
=> default 192.168.1.1 0.0.0.0 UG 0 0 0 wlan0

I think this shows similar information:
$ ip route show
=> 192.168.1.0/24 dev wlan0 proto kernel scope link src 192.168.1.3 metric 2
=> default via 192.168.1.1 dev wlan0 proto static

And, I must have edited the gateway in the past, because of this comment:
$ cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=rock
#GATEWAY=192.168.1.1

Given that the Centos Network Manager requires a gateway in its GUI, 
I'm wondering if I should use a gateway of the Nanobridge M2 (192.168.1.20)
or a gateway of my N600 broadband router (192.168.1.1).

PS: I really do not understand what a gateway is. :(

that thing has a pretty narrow beam, it will need to be aimed carefully 
and mounted on a stable bracket that will take wind load without moving.

you should be able to get 300 feet of mostly open space with a simple 
panel antenna, something like this,
http://www.microcom.us/ezgo0214pnl.html

you can put a range of radio/router boards inside that 
enclosure/antenna, like...

really?   my N600 has great range.  mine is a wndr3700v3, I'm using it 
as a bridge/access point rather than as a router.   put it up high, on 
edge, with the big flat shiny side facing the space you want to cover 
best, and nothing around it.   top of a bookcase is what I'm using.

Re: [CentOS] Fwd: When no MTA is installed, How to send an email with a cronjob?

2013-07-23 Thread Arun Khan
@ Indunil Jayasooriya

IIRC, in one of your follow up post, you mention that you have the
Zimbra suite installed and running on *this* machine (which is why you
might have had to remove the distro's default postfix in the first
place).

If above is true then you should try to figure out how to send the
cron emails using Zimbra's MTA (which BTW is also postfix).

Why are you trying to re-invent the wheel?

Am I missing something here?
