[SLUG] ip aliases and netmasks
Hi all, Running Redhat 7.3 on a server. I've got a bunch of ip aliases which I am running from /etc/rc.local to run them when the comp boots. Problem is that on boot it creates the aliased ip's but they have mask of Mask:255.0.0.0 instead of the required 255.255.255.248 An example line from rc.local is : /sbin/ifconfig eth0:0 netmask 255.255.255.248 xxx.xxx.xxx.xxx (with the x's being the additional ip addr) If I copy and paste the lines from rc.local it will update the first 2 with the correct netmask and give the following error for the rest: SIOCSIFNETMASK: Cannot assign requested address I'm guessing this could be because some services that are started are already listening on the aliased ip's. If I repeat the command 2 or 3 times it eventually sets the mask correctly. Anyone able to offer any ideas why it does this and how to fix it? Cheers, Paul

[SLUG] four-port serial board help, please?

[SLUG] KnoppixKDE
-BEGIN PGP SIGNED MESSAGE- Hi folks, Just read a really good review of the KnoppixKDE variant of Knoppix, basically it's Knoppix with KDE3.1 and all the .deb'd KDE packages they could find. The reviewer had never used Linux before (he's an MCP) and does an (IMHO) excellent job of reviewing it, including constructive comments and updating his article with responses from people with fixes, tips and tricks. His tone is of someone who's found a new toy and loves it. :-) URL for the review is: http://ammai.com/modules.php?op=modloadname=Reviewsfile=indexreq=showcontentid=2page=1 KnoppixKDE's page is at: http://www.knoppix.net/docs/index.php/KnoppixKDE I'd love to try this out, as well as possibly try and pass it out at the local Illawarra Computer Enthusiasts group (a nice bunch, they're not technically minded, just a bunch of regular Joe Users who like to get together and talk about what they've managed to do) and to others who might like to try Linux but don't want to risk damaging their existing Linux install. However, I'm on the end of an analogue modem link (too far from the exchange for ADSL and in a shadow area as far as Etherwave's concerned) and the ISO is a terrifying 457Mb in size! You can guess what's going to come next.. :-) By some chance, has anyone already downloaded this, or is anyone willing to download this, burn me a CD and pop it in the post to me ?

I need two new drives, but I much prefer reliability to size (I'm told that size isn't everything ;-) Every time I go see the friendly chinese guy down at my local pc shop for a new drive, he sells me a different brand. I asked him about this and he said that the quality of a given brand can vary greatly, because manufacturer A's drives can be made in different places at different times. He sells whatever he thinks is best this week (up to you whether you believe that!). Actually I believe him because there have been long discussions on /. about hard drives, and in the same thread you'll find slashbot A arguing that he swears by brand Foo, whereas slashbot B lost his job, car and girlfriend due to a crashed drive of the same brand. Moral of the story: ASSUME ALL DRIVES ARE CRAP. This is OK, because Linux gives us fantabulous software RAID. If you care about data integrity, get two drives, do mirroring, and the chance of data loss is very, very small. Better yet, get 3, so that you have one on hand when one dies. You should still do backups, of course. Personally I use RH, the installer makes setting up RAID pretty easy, other distros are probably not that hard either. RAID costs more, but I reckon the peace of mind is worth it. -- SLUG - Sydney Linux User's Group - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug
