Can't boot to init 3
by Mark Hull-Richter 19 Mar '07

19 Mar '07

In order to get more screen than 800x600, since the video card I'm using isn't on the list, and neither is my monitor, I've downloaded the NVIDIA "latest and greatest drivers" from nvidia.com, except it won't install. It refuses to run in X mode (unless I force it to, which it says is not recommended), but wants to run in init level 3. Problem is, I can't get to init level 3. If I run 'init 3' from a root command line, it starts to go down, waits until I type something (anything), then begins heading for init 3 and stops dead right after starting anacron. The only way to revive it is to reboot. If I run 'init 1' from a command line, it goes down to init level 1 just fine, so I fugred 'Great, now init 2' but it stops right after starting the HAL daemon. It echoes keyboard input but does nothing further at all. I have to reboot. It's almost as if it's going to a console that isn't my (only) terminal.... I tried to see how to tell grub to come up at init 3, but I can't find that one either. Help? Please reply both on list AND directly to me, at least if you reply today, because this subscription is currently set for digest (because I get all the inidividual emails at work) - when I get the video set up properly, I'll fix that.... Thanks. mhr

CentOS 5 Beta on a MacBook Pro
by Mailing Lists 19 Mar '07

19 Mar '07

FYI, I just installed CentOS 5 beta with the SMP kernel in a VMWare fusion virtual machine on my 2.33 GHz 15 inch MacBook Pro. The installation was flawless. I installed from an NFS share on my network with the ISO images. The vm booted disc one and recognized my 802.11n wireless connection as eth0. The install took about 30 minutes. Everything worked fine... -Joe

Finding Disks

Is there a command that will list the disks that the system currently has? The df and mount commands only display info about filesystems. Charles L. Sliger, Information Systems Engineer, chaz(a)bctonline.com "No matter where you go, there you are..."

prefdm still unfinished?
by Rody 18 Mar '07

18 Mar '07

After testing the beta of CentOS 5, i was a little surprised to notice that the display manager part of the prefdm file in /etc/X11 was exactly like in CentOS 4 / RHEL4 and previous versions including RH9. it reads like this (added line numbers for reference): 14 # Run preferred X display manager 15 preferred= 16 if [ -f /etc/sysconfig/desktop ]; then 17 . /etc/sysconfig/desktop 18 if [ "$DISPLAYMANAGER" = GNOME ]; then 19 preferred=gdm 20 elif [ "$DISPLAYMANAGER" = KDE ]; then 21 preferred=kdm 22 elif [ "$DISPLAYMANAGER" = XDM ]; then 23 preferred=xdm 24 fi 25 fi Line 17 is no functional command i know of, therefor the choice of which displaymanager (login-screen) to use is decided by the fallback lines later in the script (that starts with gdm). If you're ok with gdm, than there's no need for this to change. Still, it would seem that something is missing there. My best guess for what was supposed to be there: # Run preferred X display manager preferred= if [ -f /etc/sysconfig/desktop ]; then DISPLAYMANAGER=$(cat /etc/sysconfig/desktop | grep DESKTOP | cut -d '"' -f2) if [ "$DISPLAYMANAGER" = GNOME ]; then preferred=gdm elif [ "$DISPLAYMANAGER" = KDE ]; then preferred=kdm elif [ "$DISPLAYMANAGER" = XDM ]; then preferred=xdm fi fi This would make kdm your display manager when using kde as default desktop and gdm when using gnome. Although the grep part is not necessary, i added it in case someone decides to add lines to the desktop file someday... I've come across one forum post in which someone suggested to add the line DISPLAYMANAGER="KDM" to the desktop file in order to achieve the same result. For this to work the prefdm file should be altered like this: # Run preferred X display manager preferred= if [ -f /etc/sysconfig/desktop ]; then if [ -n "$(cat /etc/sysconfig/desktop | grep DISPLAYMANAGER | cut -d '"' -f2)" ];then DISPLAYMANAGER=$(cat /etc/sysconfig/desktop | grep DISPLAYMANAGER | cut -d '"' -f2) if [ "$DISPLAYMANAGER" = GDM ]; then preferred=gdm elif [ "$DISPLAYMANAGER" = KDM ]; then preferred=kdm elif [ "$DISPLAYMANAGER" = XDM ]; then preferred=xdm fi else DISPLAYMANAGER=$(cat /etc/sysconfig/desktop | grep DESKTOP | cut -d '"' -f2) if [ "$DISPLAYMANAGER" = GNOME ]; then preferred=gdm elif [ "$DISPLAYMANAGER" = KDE ]; then preferred=kdm elif [ "$DISPLAYMANAGER" = XDM ]; then preferred=xdm fi fi fi It all seems basic scripting to me so i wonder if no-one simply never noticed or never cared to finish this one.

This firewall rule will self-destruct
by Benjamin Smith 18 Mar '07

18 Mar '07

Ok, I have a challenge - get two services working over a single port. (!) Sometimes it's a web service, sometimes it's a VNC service. Here's what I had in mind: 1) Server is normally a webserver listening on port 80, and normally has the following rules active: # iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT # iptables -t nat -A POSTROUTING -j MASQUERADE 2) Server hosts a special PHP script, that when called correctly, sets rules like # iptables -I PREROUTING -p tcp -s $REMOTE --dport 80 -j DNAT --to-destination $FWIP:$FWPORT # iptables -I FORWARD -p tcp -s $REMOTE --dport 80 -j ACCEPT The *next* tcp connection from their computer to the webserver will get NAT'd to service $FWIP:$FWPORT. But I want this rule cleared out as soon as the connection is made with the latter altered rules. Is there a way to write a rule or set of rules that, when activated, then delete themselves? The "ESTABLISHED,RELATED" rule should keep the connection alive even after the latter rules are killed, right? Is this possible? Am I just out in left field?

CentOS-4.3 Install Fails
by Charles Sliger 17 Mar '07

17 Mar '07

I'm using the same CD's that I've used to install CentOS on my other systems. After the first failure I had the installation verify the install media just in case. It passed. I've tried the default install (used for all previous installs) and the i586 option (after googling). They both fail in the same way. Here is a transcript of what is output to the screen: Running anaconda, the CentOS-4 i386 system installer - please wait. Could not find platform independent libraries <prefix> Could not find platform independent libraries <exec_prefix> Consider setting $PYTHONHOME to <prefix>[:exec_prefix] 'import site' failed ; use -v for traceback Traceback (most recent call last): File "/usr/bin/anaconda", line 28, in ? import sys, os ImportError: No module named os install exited abnormally sending termination signals.done sending kill signals.done disabling swap. unmounting filesystems. /mnt/runtime done disabling /dev/loop0 /proc/bus/usb done /proc done /dev/pts done /sys done /tmp/ramfs done /mnt/source done /selinux done you may safely reboot your system Motherboard Intel D945GCL CPU Intel Pentium-4 631 RAM Aeneon 512 Mb 240-pin DDR2 SDRAM DIMM - DDR2 667 PATA Disk IBM 40 Gb PATA Disk (DeskStar) - System Disk SATA Disk Hitachi 80 Gb SATA Disk (DeskStar) - Backup Disk Disk Carrier Vantec MRK-200ST-BK Case Antec TX1050B The system disk (IBM 40Gb DeskStar) was used in a previous system ad has CentOS-4.3 loaded on it.

You're spawning one process 'grep', instead of three seperate processes, 'cat, 'grep' and 'grep' again. Am I using time right to measure it? # time cat /var/log/maillog | grep check_relay | grep -c njabl 8 real 0m0.299s user 0m0.289s sys 0m0.009s # time grep -c 'check_relay.*njabl' /var/log/maillog 8 real 0m0.404s user 0m0.402s sys 0m0.000s Is the first 'time' measuring the whole one-liner, or just the time it takes to 'cat'? I also tried this: time echo `cat /var/log/maillog | grep check_relay | grep -c njabl` 8 real 0m0.325s user 0m0.312s sys 0m0.012s time echo `grep -c 'check_relay.*njabl' /var/log/maillog` 8 real 0m0.411s user 0m0.408s sys 0m0.002s I ran these several times mixed back and forth to try and see if they were flukes, these numbers appear to be representitive of the average. What do you get on your system? Maybe passing the file name to grep gets faster as the file size increases? wc /var/log/maillog 12323 142894 1588860 /var/log/maillog I wonder if the issue here is actually the 'stuff*morestuff' as that might be a more expensive match: time echo `grep -c 'check_relay' /var/log/maillog | grep njabl` real 0m0.269s user 0m0.263s sys 0m0.006s -Ryan
