Networking / OpenSSH_7.7p1 tcgetattr: Invalid argument
« on: December 03, 2020, 10:24:43 am »
I have updated my rpm packages and so openssh-clients version 7.7p1 was installed. This version has some problems:

Code: [Select]
[C:\]ssh -V
OpenSSH_7.7p1, OpenSSL 1.0.2t  10 Sep 2019

[C:\]ssh prometheus
root@prometheus's password:
[b]tcgetattr: Invalid argument[/b]

_um_free_maybe_lock: Tried to free block twice - block=20034694 lock=0x1
pid=0x0041 ppid=0x003e tid=0x0001 slot=0x0078 pri=0x0200 mc=0x0000 ps=0x0010
Process dumping was disabled, use DUMPPROC / PROCDUMP to enable it.

The external process was cancelled by a Ctrl+Break or another process.

The problem is the line "tcgetattr: Invalid argument". I have an older Version as OpenSSH_5.3p1 as wpi installed; this version does not show the error and is working proper. Is there a solution for version 7.7p1.

best regards
