Sendmail masquerading _sometimes_ with dynamic IP

Sendmail masquerading _sometimes_ with dynamic IP

Post by David Negaar » Fri, 09 May 1997 04:00:00



Okay, here's the situation.  I have a 'sendmail.cf' file I created
some time ago (for use with a SlackWare distribution) that was working
fine as regards masquerading.  I have since switched to RedHat 4.1,
but transferred said 'sendmail.cf' file to my new system.

Sometimes sendmail masquerades correctly, but other times it sends
mail with a return address containing the (then current) dynamically-
assigned hostname.  Since my machine is one of the only machines
connected to my ISP _and_ running Linux, this can be a problem.  If my
machine is not logged on with the particular hostname/address it had
when the message was sent, and a person attempts to reply to one of
the messages sent without masquerading, the reply of course fails.

I don't any longer have my O'Reilly & Associates book on Sendmail, so
I can't just look this up.  Is there something obvious going on?

Any help would be appreciated.

1. IP Masquerading w/ dynamic IP

Hello out there,

I am using IP Masquerading and an ISP that provides Dynamic IP
Assignment at login. So far, I use a telnet session to my
Masquerade-Server and start up pppd to connect to ISP. I also tried
using diald, but the first packet always goes lost. Is there any
solution to use masq+diald+dynamic IP that would be useable?


Thanks,
Holger
