Whenever I modify my pam file as shown below I can no longer log into my centos; I have to go into single user mode and undo the changes. What I want to do is log all failed authentication attempts but I don't want it to affect the root user account.
# vi /etc/pam.d/system-auth
auth required pam_tally.so no_magic_root
account required pam_tally.so deny=3 no_magic_root lock_time=180

At this time, I need put some command so that I can enter some values and store them in a file.

View 2 Replies View RelatedI am running an application that requires use of my /etc/hosts file. In it, I have my machine name and its LAN ip address. The program creates a service on a specific port, then attempts to connect to it based on the host name. So my hosts file has to be correct.I added the nameservers to resolv.conf and now my application will not run. My guess is that the computer is checking the name servers first, timing out then checking the hosts file.Is there a way I can tell the system to check the hosts file first, then DNS. I thought it should behave that way by default, but it does not appear to.

What i want to be able to do is create a custom kickstart for my centOS 5 server. I want to create a bootable cd that I can pop in my server and basically walk away for 45 minutes and I come back and its fully installed. All the directions I have read so far tell me that I have to create a seperate ks.cfg and then I need my original centos cd to get it booted. Then the cd will ask for where the ks.cfg file is and I have to type the location. I just want to pop the CD in and type in linux_clean or something and have it perform a custom install based on the information and specification in my ks.cfg. How can I go about doing this?

View 7 Replies View RelatedI have a weird performance issue with a centos 5 running a nfs server and a rh8 client. I think the fact that it is rh8 client should be downplayed. It is just that with rh8 client the performance degradation seems more clear. See test details below OS in server is Centos 5 x86_64 kernel 2.6.18-92.1.22.el5
1Gb connection between machines File to test over NFS is a 1GB file. First of all I wanted to measure how the network alone performs while using NFS. So in the server side I run a "cat" command on the 1GB file to /dev/null. Please note that the disk read speed is about 98MBs. At this point the file system has the 1GB file cached in memory. In the client side a "cat" on the same file gives me a speed of about 113MBs. It seems then that the bottleneck in this instance is the network and it is very close to nominal speed. So the network performance is really good. (BTW I know that the server got that file from cache because a vmstat or iostat shows no disk activity.)
The second test is reading from disk with no caching involve. In the server I flushed the 1GB file from the memory. For instance by reading another 5GB file and I repeat the same thing as above in the client (a cat on the 1GB file). Now, the server has to go to disk.(vmstat or iostat shows the disk activity). However the performance, now, is about 20MBs, I was expecting something closer so 90MBs. (since the reading speed in the server in the first test showed 98MBs).
This second test was repeated for ext2, ext3, xfs with no significant differences. A similar test using a RH8 NFS server and client gets me close to 60MBs for a 1GB file not cache by the file system in the serverSince network speeds and disk read speeds are not the bottlenecks ... what or where is the limiting factor then?

I don't think this is a "perl one-liner" of find and replace. I'm trying to auto-fill some information in a listing of files. The simplest example is that in the files the following exists:
I would want the script to find this and populate it with something like -- Date : 20101004-1758
I have a few more similar fields to autofill, and I'd like to do this from within a larger perl script I'm developing to process these files. So, how I perform in-place file modification from within a perl script?
I'm getting openbox up and running on squeeze. I performed a netinstall and did a simple apt-get openboxI need to modify a file called ~/.xinitrc, but it does not exist. I read that I can copy one over from /var/x11r6/lib/xinitrc, but the /x11r6/ directory doesn't exist either. I've installed xorg, but the directory still eludes me. A package search yields nothing useful. I am using the SLiM display/login manager, which I believe calls startx, which should theoretically generate the ~/.xinitrc file.

I didn't find anything except gconftool-2 but it do not explain how to modify other files. (there is a shema file there).
there isn't a program/script to achieve this, but can easyly be made for every config file, If someone do something like that, with a little database of which markup use each file, it could become really popular.

I wanna learn how to store data in text file and be able to modify it and save as well using C++.
Note: im using Turbo C++ 3.0
I want my bash file to read from "input.dat" the two values emin emax. My input file looks like that:
#cat input.dat
!Energies
emin 10.00 !minimum energy
emax 30.00 !maximum energy
Now this seems to be not so hard with the command awk
#!/bin/bash
awk '{FS=" "}/emin/{print $2}' input.dat
awk '{FS=" "}/emax/{print $2}' input.dat
[code]....
So far so good. Now, I want to define two variables (e.g. e1,e2) in the bash file, so that their values would correspond to 00.00 and 30.00, as read from the input file. This one I have not found yet, thus asking for your advice. At the end, writing echo $e1 $e2, I should get 10.00 30.00 This is even harder to me: I want to replace the values emin,emax in a new file "modify.dat" which looks like that:
...
c---- energy interval
emin = 1.00
emax = 2.00
...
with the values e1 and e2 I have in my bash file. In other words, I want to call "modify.dat", find these two lines and replace the numeric values with the e1 and e2. At the end, my file should be like:
...
c---- energy interval
emin = 10.00
emax = 30.00
...
I have a multi user system for my roommates and myself that has separate folders for each of us. I've got user authentication working with samba, but unless I set every file and folder readable/writeable by all users, I can't browse it or edit the files.This isn't ideal as the shares are open to other users access, so I'm hoping there's a way to keep folders at 750 and files at 660 while allowing samba users to browse, delete and edit.Also, the samba share is actually a mounted NFS share from another server. Both the NFS server and the Samba server have the same users/uid's. When a file is created from a Windows host via the Samba client, the NFS server's permissions do show that the correct user owns the files, but since the files aren't mode 666 but 640 I can't edit or delete the file.
