Source: socat
Version: 1.7.3.3-2
Severity: medium
Hi, all socat versions work fine with
https://packages.debian.org/epoptes except for the current sid version,
1.7.3.3.
Please consider packaging 1.7.3.4 that doesn't have the regression.
Details: Epoptes is a computer lab management tool, I'm upstream and
Debian maintainer for it. It uses socat to forward a "student" terminal
to the "teacher". To reproduce the issue without installing Epoptes, the
following similar commands may be used instead:
Teacher (just run it in a terminal tab):
xterm -e socat tcp-listen:1234,reuseaddr,keepalive=1 stdio,raw,echo=0
Student (just run it in another terminal tab):
TERM=xterm socat EXEC:'screen bash -l',pty,stderr tcp:localhost:1234
This works fine with all socat versions except 1.7.3.3.
In 1.7.3.3, it's like line buffering is enabled or something similar,
and pressing for example the up arrow in the keyboard shows "^[OA"
instead of displaying the last bash command. Thus, the forwarded xterm
is almost unusable.
