No "echo" when telnetting to Cisco router
Last modified: 2007-04-18 12:36:43 EDT
Description of Problem:
I have a Cisco 677i ADSL-router, and I have to use telnet to configure NAT.
With telnet from fairfax/roswell, I get no echo when I have telnetted to
router and write commands - so I can't see what I'm writing. (Telnet to
localhost is OK).
This was not a problem in Seawolf, so now I have downgraded my Roswell
RC1-telnet to the telnet-0.17-10 -package from Seawolf, and it works again.
Of course, you can do a lot of configuration even if you can't see what you
are writing, but sometimes the result is unexpected.
As the "old" telnet-package still works, I think "something" has happened
the new telnet?
Version-Release number of selected component (if applicable):
Does 677i have a normal Cisco CLI or some fancy menu-driven interface?
telnet-0.17-18 on roswell2 works just fine for me (plain oldschool CLI
Could you try rebuilding telnet-0.17-10 and install it on your system (i.e., if
curses libs have changed..). Similarly, if you still have a Seawolf box around,
does rebuilding -18 there work?
If feeling adventurous, you could also try commenting out the
"telnet-client-cvs" patch in the spec file.
The telnet interface is not much fancy - just plain telnet.
Since last time I tested telnet on Seawolf, I had used up2date - and got the
same problem with the new telnet (0.17-18) as I have in the betas. 0.17-10 is
the only one of these that works for me. Rebuilding the rpms on Seawolf and
Roswell is not making any difference. 0.17-10 works on both systems, 0.17-16 and
0.17-18 does not work.
Commenting out "telnet-client-cvs" patch however gives me a "working" rpm!
Hmmm, will review the cvs patch

Patch posted to the other report.
IMO, this is a MUST-FIX issue.
(it won't come up that often as people don't use telnet much anymore, but if you
