My system has no problems accessing (telnet/pinging) systems with 129.146.210.xxx or 129.146.xxx.xxx IP addresses but when the IP looks like 129.xxx (something other than 146) .xxx.xxx, it cannot ping/telnet to it. Doing a ypmatch on 129.xxx.xxx.xxx has no problems. Any clues? btw, I had earlier posted a question that by ypmatches were returning NIS internal error ... turns out ypbind was not running. Thanks David Jansen. tia, mc __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
