Re: Port 113?
by Jochen Lillich 18 Oct '99

18 Oct '99

Gerhard Sittig <Gerhard.Sittig(a)gmx.net> writes: > This is usually referenced from the remote host back to you when > you relay mail there. Is there smtp traffic in company with these > events? You might want to log them for investigation. It happens when I open a ssh connection to the web server. Then, the server tries to connect back to my workstations port 113. But I guess it's not wise just to open external connects to port 113 of all workstations I do ssh from? Also, another thing: ssh worked not until I permitted connects from the servers ssh port to my workstations. First, I just permitted traffic from my workstations' ssh port to the server (as does the SuSE firewall script), but then it won't connect. Is this normal behaviour? Thanks, Jochen -- *** Linux BBS: Die deutsche Website fuer Linux-News und -Infos *** http://www.linuxbbs.org/

default suse webserver
by Chris Reeves 18 Oct '99

18 Oct '99

hi all, i'm intending setting up a webserver to run from my computer. i was wondering if there would be any security issues with opening up the server as it is (i have documentation server installed, although only port 80 will be open, and have all the help packages and ht://dig, etc running on the suse html help system). are there holes in ht://dig that will let outsiders search my hard drive? is there any special way i should set this up to stop this happening? basically, if i open the server up now, with all help docs, etc, installed, will i be safe? thanks in advance, Chris -- __ _ -o)/ / (_)__ __ ____ __ Chris Reeves /\\ /__/ / _ \/ // /\ \/ / ICQ# 22219005 _\_v __/_/_//_/\_,_/ /_/\_\
