we upgrade firepower 2130 from 9.10.1 to 9.16
after ugrade we can't login firepower asa by using ssh xshell ，can login fxos
from debug got
ssh 2 matching cypher is not support
actually from asa ssh cypher is support i change cypher on client but no use
i tried reconfig asa regenerrate rsa key clear xshell key cache but no use
give me some clue？
i check show ssh cipher found asa support cipher which debug said no support
I tried different ssh client putty crt xshell
and clear key cache on xshell
we will try latest ssh client and tlsv1.2 command
this is weird,
from firepower debug : asa and ssh client found match cipher , bug why asa can't support, from show ssh , I can see asa enable match cipher , we upgrade from 9.10.1 to 126.96.36.199 , it is weired , I can't find any usefule infortion
I change cipher on asa , regenarate rsa key , clear key cache on client xshell, change client computer , and change xshell to crt , but no use , asa report same error from debug.
What are the versions of Xshell you tried? I've used version 6 and 7 both and they work fine with newer ASA code. Older versions of terminal emulator programs (Xshell, SecureCRT, Putty etc.) may not support newer ciphers.
The newer ASA code deprecated some older ciphers. Your attempt to change ssl ciphers has nothing to do with ssh ciphers.
Please share the output of "show run ssh".
