You can run "dmesg" after the modprobe to see the results of the module being loaded. If you see something along the lines of SCSI subsystem driver Revision: 1.00 scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.36 <Adaptec 3960D Ultra160 SCSI adapter> aic7899: Ultra160 Wide Channel A, SCSI Id=7, 32/253 SCBs You'll know it loaded. Of course youse will make reference to Initio, not Adaptec, but you get the idea. If that works, then you should be able to add the following line to /etc/modprobe.conf: alias scsi_hostadapter initio If that doesn't work, you'll have to track down the right module for your card.

Jim- If you run kudzu (Redhat's hardware config utility) by hand as root, does it see the card and attempt to configure it? kudzu should generate the proper magic in /etc/sysconfig/hwconf and in /etc/modprobe.conf. Based on a quick google, this should be supported by the initio module. If kudzu fails to do the magic, try modprobe initio You could also add an entry to /etc/modprobe.conf alias scsi_hostadapter initio modprobe scsi_hostadapter -- Sean

Cookbook receipe for SCSI tape install requested.
by James B. Byrne 07 Sep '05

I need to install an HP Surestore dlt on a Centos 4 machine and I am at a loss as to how to proceed. Can someone either provide or point me to an online reference on how to proceed to add and configure a SCSI adapter and tape drive. I have read, but not really understood, the man page entry for st. Does kudzu handle this? Regards, Jim I am a digest subscriber so the favour of an additional direct reply is desired. -- *** e-mail is not a secure channel *** mailto:byrnejb.<token>@harte-lyne.ca James B.

/var/log/lastlog on x86_64
by Manuel BERTRAND 07 Sep '05

07 Sep '05

Hi list, this problem is already known and I'm sorry to bother if an acceptable workaround was already debated on the list. I was getting trouble with a 'grep something /var/log*' which caused the "Memory exhausted" message. With some deeper search I found the lastlog file in /var/log/ to be 1.2T sized. This seems to come from the nfsnobody's uid to be 4294967294 on x86_64 system (and -1 on i386) and the pre-allocation space for every uid (so from 0 to ...4294967294...hum..) from lastlog. Since I do not use NFS at all, can I just erase the nfsnobody from /etc/passwd and start with a blank lastlog file (this looks like a great way to nuke my system)? Or do I need to explicitly exclude this file from all my search? How do you -x86_64 users- deal with this? It seems the mainstream people don't see this as an issue. the system: 2.6.9-11.ELsmp #1 SMP Fri May 20 18:25:30 EDT 2005 x86_64 x86_64 x86_64 GNU/Linux CentOS 4 Thanks, Manuel

Hi we bought an astaro firewall and are quite happy with it, now we need to buy a commercially supported LVS (linux virtual server) appliance. Does anyone have any good experience using any commercial LVS devices with web based GUI. --

CentOS 3 -> logins
by Ugo Bellavance 07 Sep '05

07 Sep '05

Hi, Since I upgraded CentOS from 3 to 4, I get those enties in logwatch. It seems to be caused by cron, opening a session everytime it executes a task. Is that normal? crond: Unknown Entries: session closed for user root: 381 Time(s) session opened for user root by (uid=0): 379 Time(s) session closed for user user: 239 Time(s) session opened for user user by (uid=0): 239 Time(s) session closed for user backup_user: 2 Time(s) session opened for user backup_user by (uid=0): 2 Time(s) -- Ugo -> Please don't send a copy of your reply by e-mail.

Yum
by Sam Drinkard 07 Sep '05

07 Sep '05

This may be considered a newbie question, and for me, yum is a new tool. I have discovered via yum, I am *supposed* to have libf2c (386) and libf2c (x86-64) installed. Searching the two libs, I find I only have the 32-bit version installed, and I need both. Should I use yum to remove the pkgs, and then reinstall, or should I use rpm to do the installs? Again, I'm from the BSD camp, so this is all new to me. Also, are the two libs in question on the distro CD's or do I need to go out and find them, or let yum find them for me and install? Thanks.. -- Snowman

Postfix+sasl Outlook problem.
by Dominik Składanowski 07 Sep '05

07 Sep '05

I have mail server on CentOS 4.1. Sasl authorization for SMTP is enabled. Thunderbird sends mail, but Outlook get an error 554, Relay access denied, error number 0x800CCC79 Outlook has a login and password for SMTP enabled. It is strange, because there is no any sign of authorize in maillog when Outlook try to send mail. -- ____________________________________________________________________ D o m i n i k S k ł a d a n o w s k i

tripwire?
by Scot L. Harris 07 Sep '05

07 Sep '05

Is there a version of tripwire for Centos? I did a quick search in one of the mirrors but did not find one. Possibly I am looking in the wrong place.
