$HOME variable not set from init script
by Oliver Schulze L. 23 Oct '06

23 Oct '06

Hi, I'm using Centos 4.4 with: mimedefang.org + spamassassin.org Mimedefang(MD) is a perl program that calls SpamAssassin(SA) perl module. The problem I'm getting is that from update 4.4, SA does not seems to find the $HOME variable only when it is called during system boot. If you later login as root and run: $ service mimedefang restart then SA does indeed find the $HOME variable I checked the /etc/init.d/mimedefang file and the chain of commands seems to be this: /etc/init.d/mimedefang -> daemon function from /etc/init.d/function -> /sbin/runuser SpamAssassin perl module is called from the mimedefang perl program. I'm thinking that /sbin/runuser is the root cause of the problem. My questions are: - does /sbin/runuser set the $HOME at boot time? - should /sbin/runuser be called with the -l option?

Mail forwarding on a dynamic IP address.
by Rajeev R Veedu 23 Oct '06

23 Oct '06

I have a Cyrus installation with postfix and openXchange. I get the mails from catchall account with procmail and distribute with the mail server. Now I have a new site office where couples of staff members are going to be relocated. Since we have only an ADSL line on site office if there any way I could forward the mails for these staff members to another Mail Server with dynamic IP address? Any input will be really appreciated. Thanks Rajeev R. Veedu.

ARC SERVE BACKUP.
by Rajeev R Veedu 23 Oct '06

23 Oct '06

Recently we have started using Arc serve backup. The Arc server and the tape library are connected to a Windows 2000 server machine and the data files are stored on many Samba file servers. I have Linux Client Agents installed on all Linux Machine. Now the problem is that when Arc Serve backup the file it always backup the full files irrespective of setting for a differential backup. I think the Arc serve is not able to set Archive bit on the file system. But it does for windows. Has any one in the list experienced this type of problem? Any advice or guidance would be really appreciated. Thanks Rajeev R. Veedu

You can follow the full story of my testing at CentOS Bug Tracker with 1419 id, http://bugs.centos.org/view.php?id=1419 Actually i'm running the stock kernel 42.0.3 in affected host with a lil more stability appreciated than previous kernels released but not really stable in certain situations (heavy i/o load on external usb 2.0 disk). [root@fattybox ~]# cat /etc/grub.conf | grep vmlinuz-`uname -r` kernel /vmlinuz-2.6.9-42.0.3.EL ro root=/dev/VolGroup00/LogVol00 ACPI=off vga=0x307 selinux=0 [root@fattybox ~]# dmesg | grep ACPI ACPI: Unable to locate RSDP Kernel command line: ro root=/dev/VolGroup00/LogVol00 ACPI=off vga=0x307 selinux=0 ACPI: Subsystem revision 20040816 ACPI: Interpreter disabled. What's sure, the system was running rock solid with 4.3 release and 22.0.2 kernel. From that point, any update to kernel or pkgs to 4.4 (34.x.x to 42.x.x) i get the same issue. The call trace (taken from 1419 id. at bug tracker and re-pasted here) is almost allways the same, and it happends normally when lot of i/o work is performed on an USB external disk, locally or via NFS/exported.

I know usb external disks are used with scsi emulation from the point of view of kernel and they are not a really good approach for massive data storing (rather using scsi units mainly/directly) but i have almost a TB on that disks... By the way i use the workaround of not writing concurrently to that disk for a long time or for long chunks... heh, no more clues unless i rescue the old 4.3 and 22.0.2 raw hd/image for that old host serving as NAS. Don't know if all of this will be helping, anyway... Good luck! Jose.

Keyboard Fails at Login Prompt
by Eric H Christensen 22 Oct '06

22 Oct '06

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I just setup an old box with CentOS 4 and I'm having a very strange problem. The keyboard is functional throughout the startup process of the machine. I get the login prompt and I get just enough time to type in "root" and hit the enter button before the keyboard fails. I've tried a different keyboard but still the same problem. After a few repeated trials I've found that the keyboard will stop functioning after about 5 seconds from when the login prompt appears on the screen. Does anyone have any ideas on this problem?

From the sound of it, your machine has plenty of power, and you could increase this number. That may or may not help, because it also sounds like the company pulling your content is not doing so in a very polite way and is using a client that opens many, many more connections than an average browser would. I would talk to them about this, personally. robert
