Hi all
Thanks for ur suggestions.
actually i am using solaris2.5 un a sunultra1 sparc server.
wht i found that a number of terminals had been opened in the console itself.

i just closed all those terminals and now from remote machine i can telnet and open new terminals.
so what Livinfree is telling seems true.
i also checked the pt_chmod and the permission is as follows
---s--x--x 1 root bin 4388 Oct 6 1998 pt_chmod

Any other ideas..on the kernel parameters that restricts no of terminals.
Thanks and regards

Praful
