SecureCRT Version 8.7.2 (x64 build 2214) Not Connecting to Cisco Switch
SecureCRT cannot connect to switch, Putty can.
I have tried disabling every key exchange but diffie-hellman-group14. IS there a certain combination of key exchange and hmac I am supposed to select? Cisco switch logs show; %SSH-5-SSH2_SESSION: SSH2 Session request from <pruned-ip> (tty = 1) using crypto cipher '', hmac '' Failed %SSH-5-SSH2_CLOSE: SSH2 Session from <pruned-ip> (tty = 1) for user '' using crypto cipher '', hmac '' closed With default settings in SecureCRT.
