IP Tunnel in only one direction possible
by telest＠gmx.net 23 Apr '03

23 Apr '03

Hello to everyone, I have a big problem, that today the VPN tunnel is only usable in one direction. NET(1) --- FW1/VPN Gateway ---- internet ---- FW2 / VPN Gateway ---- NET(2) I can ping from NET1 to NET2 and get replies. ( I also can use different other thinks like pcanywhere, file access to the pc's on net2,...) I cannot ping from NET2 to NET1. There is nothing in the logfiles. I can only see on the interface statistik that the 4 ping packets are dropped. I use on both sides: Freeswan 1.98b iptables Suse Linux 8.0 FW1: static IP Adresses , SDSL Connection FW2: dynamic IP Adresses, SDSL PPPoE Connection I'm really stucked and help will be appreaciated.

running ftp daemon in chrooted jail - how?
by Michael Ryan 22 Apr '03

22 Apr '03

Hi list, Anyone point me to a good doc on how to set up ftp daemon in a chrooted environment. (I am running SuSE 8.1 which comes with the BSD FTP daemon ftpd-0.3.2-333 ... should I use this or would something like ProFTP be more 'secure'?) Many thanks, Michael

by Clemens Gesell 22 Apr '03

22 Apr '03

Hello folks, Why isn't there a Security Anouncement for the insecure Postscript handling Bug in KDE from SuSE. I have seen Update Packages for SuSE Linux 8.2 and 8.1, but nothing for <= 8.0 ? Thanks, Clemens

RE: [suse-security] connection via telnet, XServer, ssh
by Habichtsberg, R. 21 Apr '03

That is what I call a fast answer :-). Only 10 Minutes! Thank you, Markus and Stefan. I will try the ssh-clients. What I didn't know is that Cyqwin includes a XServer.

Re: [suse-security] Suse 7.3 Crash
by Nick LeRoy 21 Apr '03

> Hi to all! Hi. I know that others have replied, but I don't think that anybody has hit on the most likely causes. The first thing that I'd do is get a modern version of memtest86 (I think they're up to 2.9 now), boot it up, and let it run overnight, or longer. IMHO, it's grown into a pretty good RAM tester. Another great system h/w test is to boot it up into text only mode, and put it in a loop building kernels. Nothing tests RAM and the system h/w as well as gcc.. > I don't know if this subject belongs to this list, but here it goes..... > > I have a Pentium 4 2.4Ghz with 1G of RAM and instaled the SuSe 7.3 Professional distribution. > > The installed system is very unstable and once and a while it just reboots without a warning. > > I installed the stable kernel 2.4.20 and disabled APM in bios and in the kernel configuration.

When the system boots there is 126M used and after 3 hours it has > 800M used with the same processes. I also noticed that the biggest RSS process value is 11M. That's most likely just buffers / cache. -Nick -- ______________________________________________ http://www.linuxmail.org/ Now with e-mail forwarding for only US$5.95/yr Powered by Outblaze

YOU has no notion of update 8.1 -> 8.2
by Arjen de Korte 21 Apr '03

21 Apr '03

After an update from SuSE 8.1 to 8.2, YOU on one of my systems (a mailserver) fails to recognize the update. Although all packages seem to have been updated, YOU still shows "Version 8.1" in the System Information box. BTW, I run YOU though a SSH session from another system, as the server has no screen nor keyboard attached permanently. I'm a litlle worried that it will not be able to locate the correct security updates, without knowledge of the actual installed version.

8.1 Crypto FS (loop_fish2) module with recompiled 2.4.20 kernel for amd
by David M. Fetter 20 Apr '03

20 Apr '03

I recently upgraded my system and in doing so I moved from a PIII Intel processor to an AMD Athlon XP. Currently, I'm running the kernel compiled against the (586/K5/5x86/6x86/6x86MX) Processor family because for some reason when I recompile the kernel against (Athlon/Duron/K7) Processor family the kernel module for loop_fish2 doesn't build. Does anyone know how to resolve this or even if it can? Also, something of note is that I do download the kernel source trees from the mantel dist and not from kernel.org, therefore the module should be present. -- David M.
