Antispam with Postfix
by Joseph L. Casale 29 Sep '09

29 Sep '09

I am mulling over the thought of replacing my current solution, it works very well except for the following two issues: 1. LDAP recip verification for only one server, this gateway services multiple domains who's directories are independent. I need to be able to verify the various domains off of independent servers. 2. I use backup mx's, my current solution probably could work in this scenario but the support mechanism behind it is *very* weak and I can't get a perfect setup working. Spam hits the primary for a domain, gets blocked and then tries my secondary which sometimes accepts it, after which the primary always accepts from the secondary. What are some setups that use Postfix which you guys are having very good success with that isn't a burden to administer. The last thing I want to do is replace my one single app with many:) Thanks for any ideas! jlc

Slow printing to HP jetdirect from cups
by Bowie Bailey 29 Sep '09

29 Sep '09

I've googled for this and poked around linuxprinting.org, but couldn't find anything helpful. I have a CentOS 5 server with an HP LaserJet 4 attached via JetDirect with the hplip driver. The problem is that when I have multiple print jobs in the queue, there is a delay of about 15 seconds between each job. This gets very annoying when there are 10-15 one-page jobs in the queue. "lpstat -t" shows me errors like this: recoverable: Network host 'seashell' is busy; will retry in 15 seconds... This worked fine previously with the same setup on an old RedHat release (Either RH7 or RH9, I don't remember which). The problem appeared after I rebuilt the server with CentOS 5. Any ideas would be appreciated. -- Bowie

Mirror After?
by ML 29 Sep '09

29 Sep '09

Hi All, If I put a 1TB HD in my server (because they are on sale this week), can I later Mirror to a second 1TB drive without destroying the data on the first? On Windows and OS X, I know I can't do this... Thoughts? -ML

Script consumes memory
by Frank M. Ramaekers 29 Sep '09

29 Sep '09

I have the following script that when executed, consumes memory and makes the system inaccessible. All process are halted. First, I don't understand what is wrong with the script Secondly, I'm surprised that Linux allows this to run unchecked to the detriment of the entire system. ---- SCRIPT ----- #!/bin/sh FTP="/usr/bin/ftp" # VMID="asystem.ourcompany.com" VMUser="STATDASD" VMPass="STATDASD" VMDir="VMSYSA:." DataFile="data.txt" VMFile="DS8100.DATA" #--- Get some information about me #--work from the same directory as the script MYSCRIPT=`$BASENAME $0` MYSCRIPTDIR=`$DIRNAME $0` if [ $MYSCRIPTDIR != "." ] then cd $MYSCRIPTDIR fi #--- FTP to MAINT on mkmfvm $FTP -vn <<$$EOD open $VMID user $VMUser $VMPass cd $VMDir ascii put $DataFile $VMFile bye $$EOD Frank M.

freenx disconnects?
by Les Mikesell 29 Sep '09

29 Sep '09

My NX/freenx connections have recently started to drop more or less randomly after several hours. Reconnection works with everything still running. I don't think anything has changed other than CentOS updates. Is anyone else seeing this? -- Les Mikesell lesmikesell(a)gmail.com

Dualboot CentOS and Windows
by Frank.Brodbeck＠klingel.de 29 Sep '09

29 Sep '09

Hi, I have to install CentOS on a spare partition of a laptop with Windows pre installed. Is there anything I have to watch out for? Couldn't find anything in the wiki or does the installer handle this well without me doing some magic, or so? TIA, Frank.

I'll look into that though. I'd like to know the point with it. What happens when you mount 2 otherwise identical disks/filesystems? As might happen if you take a disk from a default install and mount it into another similar system? I haven't tried with a recent fedora version, but I'd guess it still won't work if you have the default LVM volume id from an install - they've gotten this wrong with every label/id approach so far. Even people who are 'no-tech' types as far as Linux goes may want to swap drives around and copy some old data or at least look at the contents before reusing a drive. -- Les Mikesell lesmikesell(a)gmail.com

Server software has been fairly 'feature-complete' for a decade or so and there's not a lot of point in using a rapidly changing distribution to run it. If you did use Ubuntu, you'd want the LTS (long term support) version. On the other hand, Linux desktop software still has a ways to go and there are more reasons to accept the new bugs that come along with new features and the need to upgrade more often. RHEL's decision to update the versions of Firefox and OpenOffice in a minor release helped, but it still feels very old as a desktop. -- Les Mikesell lesmikesell(a)gmail.com
