Debian doesn't see all RAM in a VM
by Brian Doob 02 Feb '10

02 Feb '10

I installed Debian Sarge (with 2.4.x kernel) on VMware ESXi in a virtual machine with 2GB RAM. It looks like Linux only sees 900MB of memory (according to top, vmstat and /proc/meminfo). Does anyone know why this would be happening and how I can fix it? Do I need to compile different options into the kernel? Thanks. -Brian

Shaw dropping on greylist?
by Trevor Cordes 29 Jan '10

29 Jan '10

I have an apparent greylisting issue with Shaw. I wonder if anyone else has noticed this. Shaw's mail server appears to only try either a few times or for a limited amount of time and then give up. I get lots of logs like the following (names have been changed to protect the guilty). After that, no further hits from that from address. I had my greylisting time set to 29mins, but have now changed it to 15mins to try to get within the Shaw window. Anyone else with a >16 min greylist delay might want to check their logs for similar behaviour, and/or take reports of missing emails more seriously. Please report back if you see similar behaviour. Thanks!

I just found a use for paste(1)!
by Adam Thompson 18 Jan '10

18 Jan '10

OK, I've now used paste(1) about /three/ times in my life... To re-flatten the output of egrep into a single line, as in: egrep -e '^Date:|^From:|^Subject:' $mailfile | paste -d'|' - - - Specifically, I'm working on Maildir-style files so I don't have to worry about "losing synchronization" if one of the headers is missing for some reason, and the names of the files are contained in the file "0006966d83811cd33a120e436a67d312". so: for i in $(cat 0006966d83811cd33a120e436a67d312 ); do (echo $i|cut -d'/' -f2 ; egrep '^Date:|^From:|^Subject:' ../$i ) | paste -d'|' - - - - ; done produces output like: .DNS|Date: Fri, 5 Jun 2009 21:16:22 -0400 (EDT)|From: "easyDNS Support" <support(a)easydns.com>|Subject: [easyDNS] Automated 30 day renewal reminder 2009-07-05 .DNS|Date: Fri, 5 Jun 2009 21:16:22 -0400 (EDT)|From: "easyDNS Support" <support(a)easydns.com>|Subject: [easyDNS] Automated 30 day renewal reminder 2009-07-05 which I can then feed into the next stage of parsing. -Adam

Text based spread sheet
by John Lange 23 Dec '09

23 Dec '09

I have a very wide "tab delimited" file that I need to edit in an ssh console. I've been downloading it, editing it with OpenOffice, then re-uploading it but aside from being tedious, that isn't always possible if I don't have my laptop handy. Does anyone have any recommendations for a curses based program that would make my life easier? I have no requirements other than editing and preserving the file's tab structure in columns. If it can keep the top row (the column labels) in view while editing that would be a bonus. -- John Lange http://www.johnlange.ca

Interesting effect
by Mike Pfaiffer 18 Dec '09

18 Dec '09

It seems zenity won't display if a different user is logged in. For example running it as a single line from /etc/rc.local won't bring up a popup. It may not have worked well with at either. Does anyone have a suggestion which works well with at and can be called from /etc/rc.local? I have everything else working for the public access box. Just not the notification. I figure we can leave the notification routing for a week and just post a note. Later Mike
