I looked at my logs last night after trying to send some messages from my subsidiary machine (nyarlathotep) to my sendmail server (cthulhu). Here's what I found: Apr 9 07:54:13 cthulhu sendmail[3941]: g39CsDc03941: tcpwrappers (nyarlathotep, 192.168.0.14) rejection Apr 9 07:54:13 cthulhu sendmail[3941]: NOQUEUE: nyarlathotep [192.168.0.14] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA I'm not sure why this happened, and reading the xinetd man pages isn't helping. I assume from the above that tcpwrappers refused the connection FROM nyarlathotep, rather than nyarlathotep refusing a connection (auth) from cthulhu. Does that sound right? Can anyone explain to a User With Very Little Brain why this happens? I didn't believe that sendmail was going to be hidden behind tcpwrappers --- I thought it relied on its own authentication. Sounds like I need to add an xinetd config form to permit machines in my local subnet (only) to get at cthulhu's sendmail server. Does anyone have such a form? Looked for one on google, but couldn't find anything that fit. thanks, R
