Possible Cause
Telnet server is disabled.
Too many Telnet connections
(up to five concurrent
sessions are supported via
Telnet ).
Default gateway is incorrect
(when the host used as client
is not in the same network as
the SCE Platform).
Routing tables are incorrectly
configured (when the host
used as client is not in the
same network as the SCE
Platform, and there is more
than one gateway on the SCE
Platform network).
Host is not a member of a
valid access-list.
Telnet connection may be
timing out.
