Re: [suse-security] SuSE ssh Distro in US
by Aaron K. Poffenberger 17 Nov '99

Thanks for all the responses helpful responses. On a related note (security), two questions: 1) Do I need to have the ident daemon on port 113 running? That port is currently open on the external interface on my firewall. And 2) from within inetd.conf, can I set which interface(s) I want a particular service to bind to, or is it a service-by-service config (as I've found with many, e.g., afpd)?

Permissions for /var/spool/lpd ?
by Robert Casties 16 Nov '99

16 Nov '99

Hello! What exactly has changed in lprold-3.0.44-0 concerning file permissions? I had no problems using the earlier version that came with SuSE 6.2 but when I upgraded to the new package I got messages in syslog like Nov 3 17:36:13 hera lpd[12495]: restarting lp Nov 3 17:36:13 hera lpd[12495]: lp: status: Permission denied and printjobs got stuck in the queue. Upon some experimentation I changed the permissions for the lpd directory to group writable and this seemed to help: hera:~ # ll /var/spool/lpd/ total 4 drwxr-xr-x 3 lp lp 1024 Nov 3 17:27 . drwxr-xr-x 16 root root 1024 Sep 6 18:26 .. drwxrwxr-x 2 lp lp 1024 Nov 5 16:41 drucker -rw-r--r-- 1 root root 6 Nov 3 20:32 lpd.lock I still don't have a good feeling about this solution. Can anyone explain the problem and is there any better solution?

Help, my system has been hacked!
by E_u_R_Frohne＠t-online.de 15 Nov '99

15 Nov '99

Hello, the organisation I work for has a new gateway to the Internet. There is a leased line (Telekom) over a Cisco 1003 which I cannot configure (because the Telekom doesn't allow it. after that there is a DMZ and a Firwall built with the tools that are coming with Suse-Linux 6.2. The organisation is not small and there are severall workstations with Win95 and NT containing ISDN-Cards with a connection to the Internet. In addition to that there are serveral AVM-MPR's running, connecting the network (Novell, Linux NT) to different Cities. The Problem occured on an internal Linux machine (behind the Firewall and DMZ). Here is an excerpt of the log: "Nov 10 13:58:06 bone portmap[4177]: connect from 169.254.118.212 to getport(nfs): request from unauthorized host Nov 10 14:20:33 bone portmap[4265]: connect from 169.254.216.71 to getport(nfs): request from unauthorized host" I could not see anything logged on my firewall and the DMZ, so I think that this is coming over a workstation. Am I true or is it possible to come through the firewall without a trace? Could anyone help me to identify the ip-addresses listed above? I would be very happy if anyone could help me! regards Rainer Frohne
