Package: smokeping Version: 2.7.3-2 Severity: normal Dear Maintainer,
It is not possible to use SSH probe on Debian Buster: ``` $ sudo smokeping --debug ERROR: output of '/usr/bin/ssh-keyscan -t dsa,rsa,rsa1 127.0.0.1' does not match (?^i:^# \S+ SSH-) at (eval 59) line 1. ``` because ssh-keyscan does not support rsa1: ``` $ /usr/bin/ssh-keyscan -t dsa,rsa,rsa1 127.0.0.1 Unknown key type "rsa1" ``` The solution is to apply patch: https://github.com/oetiker/SmokePing/commit/62ac9fda04b994bbf4f97d3dd1cf8b92cf279e71.patch?diff=unified ``` >From 62ac9fda04b994bbf4f97d3dd1cf8b92cf279e71 Mon Sep 17 00:00:00 2001 From: "Avinash H.
