similar to: permanent ulimit -n on CentOS 3.4

I installed CentOS on my home-server with 2 IDE 160GB MAXTOR HDD / RAID-1, LVM and ext3 partitions. Previous OS on this machine was FC2. I often "play" with LVM and, sometimes, have to extand or reduce some volumes size. I was surprised to see that resize2fs isn''t included anymore ! The replacing tool is ext2online but this one seems to only be able to grow a filesystem (not

Why can't non-uid 0 users have more than 1024 file descriptors when logging in via ssh? I'm trying to allow a user to have a hard limit of 8192 file descriptors(system defaults to 1024) via the following setting in /etc/security/limits.conf: jdoe hard nofile 8192 But when jdoe logs in via ssh and does 'ulimit -Hn' he gets '1024' as a response. If he tries to

Running across some curious stuff with ulimit on CentOS 5.10. We have a non CentOS packaged version of Asterisk (using their packages) that we start at boot time with a typical RC script. Recently it started whining that it couldn't open enough file handles. As we dug further into this, it appears that at boot time, it inherits ulimit from init, which is pretty low: 1024. We've set

Sorry for the OT post, just looking for a pointer from somebody who's been there and done that. I'm looking to write a program that will allow for managing documents that have been encrypted with AES. I want the program to be as cross-platform as possible, so at the least it needs to run in Win2K/WinXP and in linux X-windows (X.org). Now, I used to write in Java a few years ago, so

This is my first post to this mailing list, although I have been reading it for a while. Please forgive the length of my message. Also, great work! I'm trying to get Centos-3 running on an ASUS SK8V Opteron motherboard in a way that is useful for me. I've had some success, but now I'm stuck on a problem with the SATA driver. Okay, so I got it up on the network by replacing sk98lin

When restarting Dovecot 2.2.10 (via atrpms) on RHEL 6, I get the error: Warning: fd limit (ulimit -n) is lower than required under max. load (1024 < 4096), because of default_client_limit # doveconf default_internal_user default_internal_user = dovecot Should dovecot print this warning based on $default_internal_user, or based on root? As root: # ulimit -n 1024 As user dovecot: $ ulimit -n

OK- A dumb question. Will a "generic"(kernel.org) kernel work with Centos 4? My reason for asking- I'm needing to upgrade from RH9, and would rather go ahead and go with 4 for the 2.6 kernel, but I need a patched kernel (Win4Lin), and I'm not sure they will offer a prepatched version (though they probably will for EL4). Thanks! -- Chris Bryant

I need to to change the ulimit to 16384(ulimit -n 16384) on boot on Centos 5.4 64 bit. How do I do that? Been searching and have yet to find a good answer. Tried to do it in rc.local but it appears to happen to late there. Matt

Hi, I'm trying to remove any limit on open files for a user; I've set username nofiles to unlimited in /etc/security/logins.conf, but now I get "could not open session" if I try to su to the user. singhh - nofile unlimited I think this is related to PAM, so I've modifed /etc/pam.d/su and /etc/pam.d/login to use pam_limits.so: # cat /etc/pam.d/su

Cutting straight to the chase: When, if ever, does the installer offer an option to upgrade an existing installation, rather than wanting to reformat the disks? More details than you may want: I recently acquired a new PC chassis, with no operating system but with a Serial-ATA disk (which I was not expecting when I ordered it). I set the BIOS for legacy IDE mode and installed RedHat 9, then

I'm running fedora directory server on some boxes in a multi-master arrangement. The problem is that when dirsrv is lauched from init (on boot) the maximum number of allowed file descriptors (ulimit -n) is only 4096. That means that the slapd process can only accept ~4k connections, and it needs to accept ~10k or so. The value for nofile for all users in /etc/security/limits.conf (and

Hi, I?ve been trying to increase the number of open files for the dovecot user on Debian 9 and have so far, failed! I?ve tried this: # cat /etc/security/limits.d/limits_dovecot.conf dovecot soft nofile 2048 dovecot hard nofile 8192 # cat /etc/systemd/system/dovecot.service.d/service.conf LimitNOFILE=8192 But to no avail: # prlimit -p 27208|grep -i

I tried to run this: :(){ :&:;};: as a non-root user in my CentOS4 and it bring down my box to its knees. Take care. str

Hi, I'm looking to stream a large amount of conncurrent connects and want to use icecast probably on a CentOS base. The bandwidth requirements are over 60 Mbps before any overheads, I'm looking at using some Dell SC1425 machines but am not sure how many I'd need, I'd appreciated hearing your experiences and suggestions. I need to be able to stream the following simultaneous

Hello, I encountered a problem when upgrading from 3.3 to 3.4 on i386. The machine is a production name server running bind. Looks like the new rpm moved my named.conf to .rpmsave and chkconfig'ed bind to off. That's really bad. A more gentle behavior would have been to save the new named.conf to .rpmnew and not mess with initscripts. Anyone else notice that? Francois Caen

Hi, what new Dell servers are compatible and KNOWN to work with Digium TDM cards? I've looked at Digium's compatibility list at http://www.digium.com/index.php?menu=compatibility. Does this mean that other Dell servers like SC1420, SC1425, 800, 1800 are working just fine with TDM cards? Can someone clarify this? Thanks -David

Dear all, Thank you all for such a wonderful support. Hats off to all :) Few times I came across imap login issues where new users will not be allowed to login. /var/log/mail.err shows the error below Aug 12 07:57:46 mail dovecot: dovecot: pipe() failed: Too many open files Aug 12 07:57:46 mail dovecot: dovecot: Temporary failure in creating login processes, slowing down for now Aug 12

Hey, Lance mentioned yum group install. This yum group capability makes the "server" CD's more versatile than the name implies -- you only need a broadband connection to get any kind of CentOS install you want. Start with a minimal install off the CD, and then use the yum group install to conveniently get the same install you could get off the 3 CD set (only more up to date).

I have an ordering and factor problem to which there must be a simple solution! The version is R 2.0.1 (2004-11-15) on A Linux platform. A data frame H is read in from a .csv file using read.csv with as.is=TRUE. Another data frame HN is constructed from data and I want to compare two columns both named ss of the (sorted) data frames that are the same length. The problem is that HN$ss is
