email problem on nebka?
by Christian Zimmermann 26 Feb '08

26 Feb '08

I have received a few email bounces recently indicating that nebka is blacklisted by barracuda. Each time, I went to the barracuda website and asked to be whitelisted. It is still going on. Thus I google for barracuda problems, and come across this: http://andrew.triumf.ca/barracuda-problems.html Seeing this, I try to understand whether nebka is subject to any of the discussed issues. Now, aras, aacis etc. resolve into the email addresses of Ivan, Thomas and me. However, when Ivan and Thomas are unreachable, messages bounce back to the sender, even if it is a pretend sender. It seems to be what triggers barracuda to think nebka is sending spam, it is in fact error messages replying to spam. I see several of those messages in /var/spool/exim4/input, for example: This message was created automatically by mail delivery software. A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: kurmanov(a)openlib.org (generated from root(a)authors.repec.org) SMTP error from remote mail server after end of data: host snefru.openlib.org [128.252.177.195]: 550 Rejected krichel(a)openlib.org (generated from root(a)authors.repec.org) SMTP error from remote mail server after end of data: host snefru.openlib.org [128.252.177.195]: 550 Rejected ------ This is a copy of the message, including all the headers. ------ Return-path: <LolaoscarPierre(a)gamespy.com> Received: from cable200-116-62-113.epm.net.co ([200.116.62.113] helo=paola1af38a 7f8.une.net.co) by nebka.uconn.edu with smtp (Exim 4.63) (envelope-from <LolaoscarPierre(a)gamespy.com>) id 1JT6hN-0001Jn-Hp for root(a)authors.repec.org; Sat, 23 Feb 2008 21:34:41 -0500 Message-ID: <3016501c8768d$d2cb3c20$713e74c8@paola1af38a7f8> From: "Melody Lund" <LolaoscarPierre(a)gamespy.com> To: <root(a)authors.repec.org> Subject: eliminate Debt - Take Action Today Date: Sat, 23 Feb 2008 21:34:34 +0500 or This message was created automatically by mail delivery software.

nebka update

nebka has now been running without trouble for a full week. All the crontab jobs are running smoothly. The only ones I have held off are the du jobs on the whole filesystem that root was carrying out. Christian Zimmermann FIGUGEGL!

We are getting a lot of these message. From what I can tell, it is all session that time out because people do not close them. Data is propoerly saved, but these message still show up. Such messages typically happen after a reboot, but this time they do not seem to disappear. Any clue what the issue is? Christian Zimmermann FIGUGEGL!

nebka up
by Christian Zimmermann 14 Feb '08

14 Feb '08

I swung by the machine room (and will need a further change of clothes, the area is absolutely soaked with rain, including flooding in my building). I rebooted, same problem. I rebooted in safe mode, and it worked. Note that BIOS indicates that there is a RAID Adaptec. I managed to enter its configuration utility, but had no idea what to do... Be extra careful with the machine... Christian Zimmermann FIGUGEGL!

rasarchive and zimm
by Thomas Krichel 02 Feb '08

02 Feb '08

What really got us into trouble at raneb was to keep non-backup data in an lvm. Now that we have a bigger root disk at raneb, I want to keep /home there. Still that means deleting some users from raneb and move them. zimm and rasarchive are currently being moved to wotan.liu.edu. You should be able to login to these accounts there with the previous passwords, please check. Copying the files is in progress. User mccarchive has been moved to fafner.
