LFS10: strange characters in vim via ssh

derguteweka · 01-07-2021, 02:43 PM

Moin,

On brand new LFS10; facing strange problem:

If i open file with vi(m) and syntax highlighting is on, strange numbers/characters appear in the terminal, example:

Code:

set 5:81mruler

the same line when syntax highlighting is switched off in vim looks ok:

Code:

set ruler

But this happens only, if i do this via ssh connection. On the machine itself it's OK with/without syntax highlighting.
Also colored ls output and cacafire via ssh are OK.

Somehow the escape sequences for coloring might get misinterpreted i guess, but i've never seen something like this before.
Happens with the 8.2.something vim used in LFS10, but also with vim74 i just installed because on versions >7.999 vim tends to do lots of rather strange things im my opinion.
But this time the Version >8 doesnt seem to be the problem, but the ssh connection?

Any advice would be welcome...

Code:

tput setaf 1;echo foo;tput sgr0

Does the line above work as intended? What is your $TERM when you log in via ssh? Is it different when you log in locally?

Prints foo in red - i guess, this was the intended behaviour.

Up to now, i never set it on purpose. Seems to be always set to "xterm-256color", no matter if local or remote ssh (also on connecting to older LFSses via ssh, where it worked for years w/o hassle and still does).

But when connecting to the LFS10 machine via ssh and setting $TERM to e.g. "linux" or "xterm", vim looks OK.
So this will solve the symptoms of my problem, but the question still is: What has changed there?
