The man page for screen says that I can create a detatched screen running with a set command in it by doing this: $ screen -dm $command However, it doesn't work. Screen exits without creating the detached screen. If I say $ screen $command ...I get dropped into a screen session running $command as I would expect. What's the magic invocation I'm missing? Also, the next step

Hi Folks, I have some users who have a 64-bit CentOS 4.x install (current), which was installed with @Everything and then some annoying packages strategically removed (mrtg, pegasus*, mailman...) and they have decided they have a need for php5. I find on the web this instruction for doing this: http://www.centos.org/centos/4/centosplus/Readme.txt So I try to do this, and I get: # rpm -e

Installing through PXE, interactively from an NFS source. The installer is in text mode even though I have 512MB of memory. Two questions. 1. When installing package sets, I do not see an "Everything" option the way there was in 4.x. Should there be? I also don't recall being asked if I wanted Server/Workstation/Custom groupings. 2. When partitioning the disk, if I

Hi folks, while chasing down a logging-related situation, I happened to notice that when I connect via ssh to my system it makes the following logs: Nov 15 14:15:39 saturn sshd[29868]: Accepted password for dave from ::ffff:10.0.10.14 port 2833 ssh2 Nov 15 09:15:39 saturn sshd[29867]: Accepted password for dave from ::ffff:10.0.10.14 port 2833 ssh2 Nov 15 09:15:39 saturn sshd(pam_unix)[29869]:

Hi folks, I have an HP Proliant 140DL G2 server with what appears to be an IDE drive in non-DMA mode. Performance on the server is extremely bad when large amounts of disk activity is taking place. I think the problem is that my drive is not in DMA mode: # hdparm /dev/hda /dev/hda: multcount = 16 (on) IO_support = 0 (default 16-bit) unmaskirq = 0 (off) using_dma = 0 (off)

Hi folks, I thought I saw a comment on this list a ways back about a firefox plugin that would make a browser automatically cycle through the tabs it had loaded. We'd like to use this to load some monitoring systems in tabs, and then have the browser cycle through them so we have a poor-man's status display station. Does anyone know more specifics about this plugin I think I heard

Ok, so if you tuned in last time, I couldn't make the installation/upgrade of PHP5 from the Centos4 CentOS Plus repository work. Not one to be easilly dissuaded, I shapened my shovel and dug myself a hole. So using the exclude= lines in the repository config file backfired big time: even if I excluded the exclude= lines, yum continued to exclude the files on those lines, and only deigned to

Hi folks, I've recently replaced a RedHat EL 3.x system with a CentOS 5 system (fully yum'd as of Tuesday). This was a full-pave install, although we did copy the sendmail.mc from the original system. Now I get a lot of this in my logs: Dec 7 11:47:38 mail sendmail[20117]: lB7Gl6w0020116: timeout waiting for input from local during Draining Input The only thing even remotely

Hiya folks, Maybe someone can help me with this question. I'm a long time mutt user. However in recent years, I have been a member of an increasing number of mail lists. And an increasing number of mail list users are starting to use special characters in their emails that my terminal is not understanding correctly. When it doesn't understand the character correctly, it starts to

Anyone seen this before? I have a number of file systems nfs mounted onto clients running various versions of CentOS (and Upstream), although mostly they are v5.x flavors. =20 The server is a Network Appliance filer. When the build process for this team runs, it sometimes dies because it can't find files in the automounter tree; if the engineer checks, he sometimes sees a problem, and

So I'm trying to RAID-1 this system which has two identical disks installed in it, and it isn't working for some reason. I started by doing a CentOS-4 install on /dev/sda1 as root, and with /dev/sda2 as my swap. I finish the install, yum update, and then I want to make the mirrors. I copy the partition table from one disk to the other: # sfdisk -d /dev/sda | sfdisk /dev/sdb I create

Hi folks, Here's the situation. I have a group of engineers who love to save things to disk. Now that the filer is getting full, they are interested in archiving some of those things to DVD. The tress containing the things they want to archive are specified like so: /path/path/path/A/04?? /path/path/path/B/04?? /path/path/path/A/05?? /path/path/path/B/05?? /path/path/path/A/06??

Hi folks, I've just spent about six hours messing around with an HP DL585 G2 server trying to get CentOS to go. This box is a dual-CPU with dual cores and 10GB of RAM total. According to the datasheet, the POST screens, and the BIOS, it has the Broadcom embedded NICs in it. The problem boils down to the installed OS (4.4 x86_64) not seeing the NICs. If you do an lspci on the system

Hi folks, Stupid question time, possibly only tangentially related to CentOS, and I apoligise in advance. I have a bunch of CentOS 64-bit boxes, and I have developers who want to run eclipse on these boxes. So I have downloaded the 64-bit bundle of eclipse, installed the java from java.sun.com, and the result is that Eclipse won't run. It chugges away and then reports: $

I have a CentOS 4.6 server running dhcpd. One of my client devices (a Panasonic KX-HCM280A camera) is trying to get a lease from that server. I can see the device accept a lease (it is a reservation), however it always releases the reservation after about 25 seconds: Jul 10 10:30:49 stargate dhcpd: DHCPDISCOVER from 00:80:f0:56:46:30 via eth0 Jul 10 10:30:49 stargate dhcpd: DHCPOFFER on

Hi folks, I've followed a set of instructions I found on http://www.linuxtopia.org/online_books/centos_linux_guides/centos_enterprise_linux_sysadmin_guide/ch-diskless.htmli which describes using system-config-netboot to set up PXE booting. I used a CentOS-4.3 install (custom, all options de-selected, then anaconda-busybox installed after the fact) as a reference/base. I followed the

Anyone had any success with or hints for a system based on the Asus P5B-VM DO board, or the Intel Q965 (with its associated Intel GMA 3000 VGA chip) in general? I had to put pci=nommconf in order to get the installer (CentOS 4.5) and the installed system to boot, but I can't get the graphics to work. Following the instructions at the Intel website

OK so at some point I borked my mysql 4.1.20 installation on my x86_64 system. Possibly relevant: I have enabled the centosplus repository in yum.conf because I needed a package from there. I have not upgraded mysql from there. Everything was working, then "something" aparrently happened, and now mysql won't start. The logs say: 061031 11:37:38 mysqld started 061031 11:37:38

Hi folks, I updates one of my long-running CentOS 4.x systems today, and afterwards it wouldn't boot properly. My issue was that it would start, then announce: Checking root filesystem /dev/md0 is mounted. e2fsck cannot continue. After much twiddling around, I discovered that if I booted from the first kernel I had, it would boot properly. Now this is a hand-rolled RAID, not an

Some people don't know how to conduct themselves on usenet and mailing lists. Despite the mailing list guidelines being crystal clear about no html posting and not top-posting we have people still doing so. People still use text-readers to access the mailing list so you could be denying access to these people by flouting the mailing list guidelines. This is an example of top-posting
