|0000075||Bananian Linux||[All Projects] Security||public||2014-12-12 01:42||2015-01-06 09:28|
|Status||resolved||Resolution||unable to reproduce|
|Target Version||Fixed in Version|
|Summary||0000075: SSH key generation creates empty keys|
|Description||In headless setup/startup of current image emtpy SSH host keys are generated. |
This in effect prevents ssh to the headless device. SD card must be mounted in
PC and zero size keys deleted.
|Steps To Reproduce||download current SD image and start in BananaPi + attempt SSH|
|Tags||No tags attached.|
|Is anyone able to reproduce this issue?|
I have been playing with the image for the past 1½ week and installed it 3 times and always headless.
Always the keys were generated correctly and also when I generate (user) keys to be able to connect to other systems or create a pub key to connect to the bananapi.
The only think that strikes me is that the ServerKeyBits are still set to the old default of
ServerKeyBits 768 (/etc/sshd_config).
For ssh hardening it would be better to set it to 1024 (or perhaps even to 2048) and regenerate
For most "home installations" this is not a problem, but mine is exposed to the outside world (but
maybe I'm overconcerned)
I can't reproduce the problem. Maybe you interrupted power supply while initial key generation?
Thanks for the remark hvdwolf. I will create a separate ticket for this.
