Our security admin has had repeated problems with disabling RPC on Sun Ultra-60's running Solaris 2.6. After disabling it, he says telnet and some other tcp services start hanging.
If the purpose of disabling RPC was to improve the security of this system, shouldn't you also turn off telnetd (and rshd/rexecd) in favor of ssh? In any event, check /etc/nsswitch.conf, and make sure that you are not using NIS for any services because NIS lookups will want to connect to the ypserv RPC service via a portmapper lookup. -Chuck Chuck 'Sisyphus' Swiger | chuck () codefab com | Bad cop!
