[ssh] random failure in client script (KeyExchange signature verification failed) #2971

Closed paoloantinori closed 9 years ago

paoloantinori commented 9 years ago

Not very often as a matter of fact, but always happening if I use the following script that retries the operation 1000 times.

for i in {1..1000} ; do bin/client -v -a 8101 -h localhost -u admin -p admin status || break; done;

I see @gnodet in this commit on Apache Mina, maybe he knows more if it's a known bug

This is a generic Apache Karaf issue. Can we track this in Apache Karaf issue tracker or JBoss issue tracker

This seems no longer present in 047 6.2 kit.
