Of all the gin joints in all the towns in all the world, Claude Cote had to walk into mine and say: > Hi Bill, > > I'm very grateful for your help.

Hm... do you actually have an NIS slave server running? Normally, you should only see the 'Pushed %s map' message if you comment out the 'NOPUSH=True' line to enable propagation of maps to slave servers. One possibility here is that you do have a slave server, and the client is bound to it, but your map updates aren't being propagated to the slave properly. If you really do have slaves, did you remember to add them to the /var/yp/ypservers file? > Maybe something is missing on the client side? I will keep on working... I think it is something on the client. Like I said, if you have a slave server, and you aren't pushing map updates to it correctly, that could hose the client. Also, did you check that you enable NIS access to the mail.aliases map in the client's /etc/sendmail.cf file? Did you restart sendmail on the client machines as well as the server after you added NIS support to the config file? Can you confirm that sendmail on the client was really built with NIS map support? If you copy the sendmail binary from the server onto the clients, does that work? If you do % sendmail -bt > 3,0 toto does it resolve the alias correctly? If you can do % ypmatch toto mail.aliases and that works, but sendmail can't resolve the alias when you run it in test mode, then it could be your sendmail configuration. -Bill -- ============================================================================= -Bill Paul (212) 854-6020 | System Manager, Master of Unix-Fu Work: wpaul@ctr.columbia.edu | Center for Telecommunications Research Home: wpaul@skynet.ctr.columbia.edu | Columbia University, New York City ============================================================================= "If you're ever in trouble, go to the CTR.
