Hallo Buddy, I still have not succeeded to configure talk. I have one NIS server in my LAN. Every linux machine will log in into the NIS Server except mine. This what I have done to my machines : 1. completed a proper "/etc/hosts" file. I registered all of the machines in my LAN in there. 2. install talk and talk-server. 3. uncommented this lines in the "/etc/inetd.conf": talk dgram udp wait root /usr/sbin/tcpd in.talkd ntalk dgram udp wait root /usr/sbin/tcpd in.talkd 4. Activated "inetd". I tested my talk with this way : I used 2 machines to test this talk program. One machine named "scrtry" and another is "psubroto". the scrtry is running NIS-Client and logged into NIS server . psubroto is also running NIS-client but only logged in locally (into psubroto local machine). I tried this command : " talk jlampert@scrtry " but I got only this error message : " No connection yet ---[Error on read from talk daemon : connection refused. Press any key.....]--- " And than I got another display of talk program : " [Checking for invitation of caller's machine] " If I tried from scrtry to psubroto like this "talk prabu@psubroto (non NIS account) than I found this error message : " No connection yet ---[Error on read from talk daemon : connection refused. Press any key.....]--- " Anybody would be so nice to tell me... please..... __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.
