Description David Lehman 2005-03-18 17:45:42 UTC
Description of problem:
We define KLUDGELINEMODE but not LINEMODE when building telnetd. As a result,
clients can't set linemode.

Version-Release number of selected component (if applicable):
telnet-0.17-26

How reproducible:
Always

Steps to Reproduce:
1. telnet into an RHEL3-U4 box
2. try to set linemode ('~^]mode line<enter>')
3.
  
Actual results:
kludgelinemode is entered, which "features" unsupressable echo of characters

Expected results:
"mode line" should cause telnet to enter linemode

The kernel has no EXTPROC and TIOCPKT_IOCTL support. A patch like:

is needed.

Comment 2 Ernie Petrides 2005-04-19 21:01:00 UTC
Please consider working with the Upstream Linux community (LKML) to add
the functionality you desire.  Since this support is not Upstream in
either 2.4 or 2.6, we're not likely to consider adding it in RHEL3 a
kernel.
