ftp mirror in Turkey
by Peter Nixon 12 Oct '01

12 Oct '01

Hi Guys As I: a) have noticed that there is no suse ftp mirror in Turkey b) Happen to work for a company that owns one of the larger ISP's in Turkey I have put up a SuSE mirror at ftp://ftp.susesecurity.com/pub/suse/ This is for public ftp access for anyone in Turkey (and North Cyprus etc) We have approx 15MBit of total bandwidth to other Turkish ISP's, but bandwidth from Turkey to the rest of the world is more limited, so I ask that you use the normal mirrors if you are NOT in this part of the world... The mirror is still in the process of populating, but the 7.2 intel updates are now up to date, so I thought it was worth mentioning. Once the initial mirror has finished (probably another day at this speed..) it will be updated twice per day.. Happy Downloading -- Viel Spaß Nix - nix(a)susesecurity.com http://www.susesecurity.com

Is there a central list of blacklisted sites that i can check to see if i'm on it? I cant think of any good reason for this - we're an educational college. Maybe one of the staff has been playing silly buggers. thanks, Elf

At least it looks like that. But what does the "pB" and "5" strange users mean? And the dates are not so true. The /var/log/messages is regular, except for: Oct 8 05:10:03 main in.ftpd[16381]: connect from rg(a)217.128.174.129 (217.128.174.129) rg is not an user in my system! Just checked Oct 8 10:56:13 main in.ftpd[17131]: connect from root(a)203.90.83.203 (203.90.83.203) and root cant connect to ftp when I try it. What does these entries could mean? I have brought down my pc and I have checked passwd and log files with the suse rescue system. Everything looks as regular as when I did that with the compromised (?) system. My system is a Suse 7.1, the only open ports are the 22 (ssh) and the one with ftp (21). I use in.ftpd (the standard type in inetd.conf). last gives me the same problem with a laptop pc, which is not directly connected to the internet, but it is often in the same network as the other compromised system. Anybody can tell me that I am not hacked and there are only common bugs??? Praise

NIS, /etc/passwd and '+::::::' question
by Tobias Burnus 11 Oct '01

11 Oct '01

Hi, YaST by default creates a '+::::::' entry for NIS in /etc/passwd. I read that the entry should have a '*' in the second field in order to prevent logins of the user '+' when NIS is down. Is this a security problem under (SuSE) Linux or is this note a remedy from an ancient ancestor? (I quick test didn't work, but I haven't tried the +user, -@group etc. syntax I found in the FreeBSD passwd(4) but neither in Linux passwd(4) nor in the yp*(*) of Thorsten Kukuk.) Tobias -- This above all: To thine own self be true / And it must follow as the night the day / Thou canst not then be false to any man.
