Time Event
it went wrong where?
I've been running for several months a qmail system on top of what use to be a sendmail. Well during some upgrades on that RH box, apparently the mail system broke. The upgrades apparently upgraded sendmail, and now it wants to be boss again. I can still see qmail processes running, but when I try to send mail from the site it never arrives, and I see a sendmail process spring up but still nothing is sent. I check the /var/spool/mail/root and I'm finding mail in there with this error message as the reason for not being sent:

DSL/iptables problem
At work, we have a very small network, just a server and a couple of clients. The server is running SuSE 7.2 on Kernel 2.4.4 and hosts our Samba shares and the clients are mostly WinNT.

I installed PPPoE on the server today and it works very fine on the server itself. But, try as I might, I can't get the clients to connect to a site outside the network.
I am not sure if its a server or a client problem.

I clamped the MRTU.
I played around a bit with iptables: iptables -A POSTROUTING -t nat -d 0/0 -j MASQUERADE
Then I realized that no client could connect now to Samba and changed to: iptables -A POSTROUTING -t nat -d ! -j MASQUERADE

But it still won't work.

I also played around with the client settings but NT just does what it wants.

Somebody in here is bound to have done this before.. Could you please give me some pointers where I am going wrong on the server and the clients? Help is greatly appreciated!

Current Mood: distressed
