Hi,

this is where it goes wrong. Look at the indicated file/line, and
you'll see that TelnetIOSPing is sending the command 'ping' and
expecting back the line 'Protocol [ip]: '. Apparently your router
sends back something else - maybe Cisco has changed the output a
bit in newer IOS versions or something...

Try a manual telnet and see what really comes back after the 'ping'
command.

If there are lots of differences between your router's output and
the TelnetIOSPing expectations, it might be useful to uncomment the
debugging lines 148-150 and look at the resulting logs (see the
'Debugging' section in TelnetIOSPing docs).

If all else fails, you might want to try IOSPing, which doesn't seem to
care at all what the router sends, or CiscoRTTMonEchoICMP, which does
the measurement by SNMP shouldn't therefore be as fragile as the
telnet/rsh based ones.

(I'm CCing the smokeping-users list again, as others might find this
useful as well.)

HTH,
