Thank you for your feedback. I have checked new log, and then Ubuntu uses HMAC SHA1
algorithm to connect to the remote host. However, Tera Term fails to connect by using
HMAC SHA2 algorithm. So, I do not know why SecureCRT is successful to connection
because no detail log exists.
I have a suggestion. Please try to connect to your Terminal server while changing
top of order regarding HMAC algorithms in the MAC order of TTSSH setup dialog.
Top of order Case 1:
Top of order Case 2:
Top of order Case 3:
