I'm running a P-100 and 386 over Ethernet and have established connectivity (ping, telnet, etc. work in both directions). However, I'm only able to sendmail from the 386 to the P-100. When I run the command sendmail -vt email@example.com from the P-100 -> 386, I get the following
firstname.lastname@example.org ... Deferred: Name server: my.host.name.: host name lookup failure
When I installed Linux, I configured sendmail w/o DNS. I have not modified the sendmail.cf files on either host. And there is more ...
I have configured my P-100 to connect to my ISP via PPP and when the daemon is invoked and the link established (verified with ifconfig for ppp0), I can sendmail "all day" from the P-100 to the 386 and vice-versa!
So ... what is preventing me from using sendmail from the p-100 -> 386 when pppd isn't running?
Thanks - Bill
