Firewall Script (Not using NAT)
by Neil White 01 Nov '04

01 Nov '04

I have been asked by my boss to firewall a server that we have down in a datacentre, but I am a bit lost as to where to start. I have looked on the internet for sample scripts but they all seem to be related to people running NAT based firewalls. I simply need a script that will restrict access to certain ports and services, and block everything else. Can anyone point me in the direction of some sample scripts that I can look at to learn / adapt to my use ? Thanks Whitey

Keeping system UIDs and GIDs across re-install
by Michael James 01 Nov '04

01 Nov '04

One of the advantages of doing an OS upgrade (instead of a new install) is it looks at your existing passwd file and keeps the old UIDs. But I don't trust upgrades, I install into new partitions and merge in the customisations of the old machine. This gives me a new passwd file sometimes with changed UIDs. Then I have the messy job of changing them back and finding any new owned files to change them too. It's a big machine (800 Gig) to run this command from root: find . -user <old-UID> -exec chown <username> {} \; Note this is only a problem for system entries (dhcpd etc.) real users have UIDs above 1000 and can be added later simply by appending that part of the old passwd file. I do have to keep system UIDs consistent as I have multiple machines running different steppings of Suse and sharing files. 3 questions: Is there a way of feeding the old password file into the install to ensure existing UIDs are preserved? Do the Suse UIDs depend on which packages are installed? Could I build things from a published, reliable list "These are the numbers that Suse will always choose"? michaelj -- Michael James michael.james(a)csiro.au System Administrator voice: 02 6246 5040 CSIRO Bioinformatics Facility fax: 02 6246 5166

Re: [SLE] 9.2 printers Q

---------- Original Message ------------- Subject: [SLE] 9.2 printers Q Date: Sun, 31 Oct 2004 18:27:28 -0500 From: Doug McGarrett <dmcgarrett(a)optonline.net> To: suse-linux-e(a)suse.com Hopefully 9.2 will show up on my doorstep in a few days. If I have two printers installed, will it find both of them? (They will both be on LPT ports.) If it will not, I will disconnect the color printer aned leave the Laserjet. The color printer is manually shared at present with another old computer, and is not always connected to this one that I will put 9.2 on. --doug _______________________________ Doug, Off-hand, I cannot think of a reason why SUSE wouldn't detect both of them - assuming SUSE recognizes them. Are the printers on separate boxes, or do you have 2 LPT ports on one box? Unless SUSE has problems with multiple LPT ports (which I would have to see to believe), you should be good to go. If you're talking about networking the two boxes (each with its own printer), again, you should be o.k. I've never hooked up more than one printer to a PC, even under Windoze, so take my input with a grain of salt.

network start fails on boot
by Patrick Shanahan 01 Nov '04

01 Nov '04

About eight months ago I installed SuSE 9.0 Pro on a friend's XP machine on a newly added hard drive as dual boot, with linux default. My friend is *not* what you would call computer literate. I directed him to some beginning linux courses on the web and gave him my 9.0 manuals to read/referrrence. He has slowly become about 75 per cent linux user, booting windoz only for streaming media that we cannot seem to make work in linux. A couple of days ago, he booted windoz for an hour and returned to linux to find that he could not access the net. Previous he had had no problems accessing his cable connection thru a router. I ran ifconfig and it only showed lo, so I ran 'rcnetwork start' and ifconfig showed lo and eth0. Access to the net was restored. I ran yast2 to check that network was enabled in runlevels 2,3,5. It was. Rebooted to see if the network would start normally and again, the network did not start. rcnetwork start restored net access. Knoppix and the SuSE 9.2 Live CD both provide net access w/o user intervention. I do not know what else to check, suggestions welcome. -- Patrick Shanahan Registered Linux User #207535 http://wahoo.no-ip.org @ http://counter.li.org HOG # US1244711 Photo Album: http://wahoo.no-ip.org/photos

9.2 and two problems
by Donn Washburn 01 Nov '04

01 Nov '04

Hey Group; Two problems have surfaced in 9.2 after upgrading from the Update sites. 1. Yast finds and has setup the sound. "Test" works, however, KDE has not. Mixers claim that the resource is locked or busy. I cleared my /home/lil-me/kde directory with no change to the sound problem. 2. SuSEFirewall is at boot time complaining about ipfwadm.ko already in use. I have looked all over etc for it and final tracked it to /usr/sbin/SuSEFire*. That is where the error is coming from. -- 73 de Donn Washburn __" http://www.hal-pc.org/~n5xwb " Ham Callsign N5XWB / / __ __ __ __ __ __ __ 307 Savoy St. / /__ / / / \/ / / /_/ / \ \/ / Sugar Land, TX 77478 /_____/ /_/ /_/\__/ /_____/ /_/\_\ LL# 1.281.242.3256 Dump Microsoft Software - Stop virus email Email: n5xwb(a)hal-pc.org " http://counter.li.org " #279316

NTP Server - US Daylight Savings Time
by Ann Hopkins 01 Nov '04

01 Nov '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I always tell myself that I need to write down how I solve this problem twice a year, but I either lose what I wrote or I just forget. I run an ntp server for the pc's connected to my home network. When daylight savings times rolls around I get errors about too large a difference to change the time. How would I fix this? The best I can remember was I had to reboot the server and go into CMOS to change the time.

Apache PHP and no email
by Warren Mason 01 Nov '04

01 Nov '04

I have a standard installation of 9.1 and I am attempting to get a web page to send mail. I have tried varions scripts (all of them work on a redhat server) but they all stop at the same point and don't send any mail. If I do somthing simple such as <?php mail("me(a)my-real-email.com.au","test message","This is a test"); ?> The error is Fatal error: Call to undefined function: mail() in /srv/www/htdocs/test/mailtest.php on line 2 Can anyone tell me why the mail() function is missing or how to get it working? I thought is was a core component of PHP. thanks in advance Warren ----------------------------------------------------- This message is intended for the addressee named and may contain confidential information.

Burnatonce or equlivalent for Linux
by Peter B Van Campen 01 Nov '04

01 Nov '04

Hi, Has anyone enough experience with burning DVDs on Linux to tell us if there is anything like Burnatonce for us. I have used Burnatonce on XP with CDs but have never used it for DVDs. I note that burnatonce used a "plugin" called ProDVD which requires a Free Non-Commercial Lic key from Frauhofer. I would love to hear your sucess stories about writing and copying DVDs.
