Hi,

it came to my view 
(https://forum.ipfire.org/viewtopic.php?f=27&t=15377&sid=a93f68dc580a6301bb3afe3a85d0c44d#p92425) 
that there is an update for 'arping'. New version is 2.15 (IPFire: 
2.05). Having the time, I tried.

First results:

- After some lfs-changes building seems ok, Diffs are as follows:

***SNAP***

Resulting binary is a bit small. Smaller than expected. Ok, nevertheless 
- ("...this will NOT work...!") -  copied it to '/usr/sbin' (after 
making a backup... ;-) ).

Rebooting the machine showed no visible problems. At first. But after 
starting SSH, I couldn't no longer login with PuTTY. Exactly NOTHING 
happens.

SSH-Log shows:

...
11:18:02	sshd[2852]: 	Server listening on 0.0.0.0 port 222.
11:18:02	sshd[2852]: 	Server listening on :: port 222.
11:18:02	sshd[2859]: 	error: Bind to port 222 on 0.0.0.0 failed: Address 
already in use.
11:18:02	sshd[2859]: 	error: Bind to port 222 on :: failed: Address 
already in use.
11:18:02	sshd[2859]: 	fatal: Cannot bind any address.
...

Copied the old 'arping 2.05' back to '/usr/sbin', rebooted, PuTTY works.

Ok, so there is something missing (in lfs!?), probably 
configure-options, which is beyond my small programming skills. If 
anyone is interested in the new 'arping'-version and capable of this: 
any hints are welcome. ;-)

Best,
Matthias
