Flowchart 4 Procedures

•Execute telnet(1M) to a remote host. If successful, stop.

•If not successful, try to establish an ftp to a remote host. Unlike telnet, ftp does not use a pseudoterminal (pty) driver on your system. This will determine if pty is why telnet failed. If ftp is successful, call your HP representative to determine why you have a problem with pty.

•If ftp fails, check to see if TCP is conﬁgured on both hosts by verifying the /etc/protocols ﬁle. Telnet and ftp work at transport layer and require TCP. If TCP is not conﬁgured, conﬁgure now and repeat Transport Level Test.

•If TCP is installed on both hosts, telnet to another host and/or use netstat(1M)to check for lost packets. If network is congested, you may need to reconﬁgure network. If network congestion is not the cause, more detailed network diagnostics are required. In either case, call your HP representative.
