I think that I can reproduce myself, but when reporting a YaST bug is nice to provide logs as documented here:

If I'm not wrong there is no /usr/sbin/logresolve2, isn't it?

> /usr/sbin/logresolve2: No such file or directory

This message goes to /dev/null apparently, instead of being passed on to the operator.

I tried { ln -T /usr/bin/logresolve /usr/sbin/logresolve2; }; the error went away but the result is empty because logresolve is incompatible with tail -f---apparently, it waits for the input to end before printing anything.

Yep, that is what I have already reproduced too.

So, will add it to the backlog in order to be fixed.

Thnx for the bug report!

# This is why tail -f will not work
let i=010000 &&
while let i--
do printf 'localhost %d \n' "$i" && printf>&2 '%d ' "$i"
