telnetd support for LINEMODE not enabled at compile time
Last modified: 2007-11-30 17:07:06 EST
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 Additional info:
The kernel has no EXTPROC and TIOCPKT_IOCTL support. A patch like: http://www.ussg.iu.edu/hypermail/linux/kernel/9911.3/0650.html is needed.
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.
