Dear all, I am trying to share the internet connection from my linux box to the other PCs on the network. I have no reason to have a firewall since this machine dials in check e-mail and dials out immediately. Can someone please help me with this one? Masquerading perhaps?? Chris PS: SuSE 8.1 out of the box PS2: I am a very new user!!!

Patch for /sbin/conf.d/SuSEconfig.postfix fuer SMTPD-User Auth
by Daniel Wirth 01 Dec '03

Dear List, in order to make smtpd user auth (server-side) work postfix, I had to apply the attached patch. It makes SuSEconfig insert the option "permit_sasl_authenticated" to the line "smtpd_recipient_restrictions" in postfix' main.cf. Otherwise I got a "relaying denied" in spite of corrent SMTP authentication. What do you think? Best Regards Daniel PS.: Patch for /sbin/conf.d/SuSEconfig.postfix: # diff -u /root/SuSEconfig.postfix.original SuSEconfig.postfix --- /root/SuSEconfig.postfix.original 2003-12-01 11:11:16.000000000 +0100 +++ SuSEconfig.postfix 2003-12-01 11:13:07.000000000 +0100 @@ -335,6 +335,8 @@ postconf -c $TMPDIR -e "smtpd_sasl_auth_enable= yes" CURRENT=$(postconf -c $TMPDIR -h smtpd_client_restrictions) postconf -c $TMPDIR -e "smtpd_client_restrictions= permit_sasl_authenticated, $CURRENT" + CURRENT=$(postconf -c $TMPDIR -h smtpd_recipient_restrictions) + postconf -c $TMPDIR -e "smtpd_recipient_restrictions= permit_sasl_authenticated, $CURRENT" else postconf -c $TMPDIR -e "smtpd_sasl_auth_enable= no" fi

SSH Users
by Barry Gill 01 Dec '03

Hello all, I have a list of users on my machine and wish to only allow one non-priveledged user ssh access to the machine. This user will also be allowed to run the 'su' command to gain root access. How do I prevent the remaining users from being able to ssh onto this box? (users continue to argue about password complexity and the like so access to any external service is now nbeing removed forcibly.) Barry
