I am looking for the scsitools package for fedora. Ubuntu has such a .deb named "scsitools". Specifically I need to find out the vendor, serial number etc. of hard disks connected to a machine.

scsiinfo -i <device> and scsiinfo -s <device> seem to do the task nicely on debian based systems, but I was unable to find a .rpm package.

Where can I find this package, or is there an other way on Fedora to get this information?

I have a Zope server (just a long running python process) which tends to eat up all RAM on my server after a couple of days. I do not want to restart it every night - maybe it's better to limit the RAM for this process and see if it can work anyway.

So, how can I restrict this process to use not more than 256MB of RAM?

The Server is a 64bit Intel machine running Centos 5.3. I heard of ulimit to restrict a bash process, but how can I restrict it for a python process?

Update:

Thank you for your ideas! I am going to use a mixed approach for my problem:

  • I'll start the service with ulimit so it can only use 256MB RAM
  • Since I have my system monitored by Nagios, I'll use a nagios-check command to verify that my process is not using more than 192MB.
  • If my process uses more than 192MB, then a graceful restart will be initiated automatically.
  • If my process uses more than 220MB or the process does not run at all, an admin (myself) will be informed via SMS/E-Mail, so I will handle the problem manually.

That way I guess that I am on the safe side: automatic graceful restarts when needed (via nagios), and forced service stops (via ulimit) in case of a sudden peak in its RAM usage

I am occasionally receiving error messages from mail servers with the above message. It seems that at least one line in the e-mail has more than 999 characters and therefore the e-mail is bounced.

Is this "by design"? in an RFC? Or some weird pseudo-spam-filter? Or just a bad mailserver?

I googled around a bit but did not find a competent answer. Hopefully one of you guys can enlighten me.
