ssh -vvv time@server and the output has been uploaded here. I found that when proceeding to each of these three lines in the output, it is particularly slow:
debug1: Next authentication method: gssapi-with-mic debug1: Unspecified GSS failure. Minor code may provide more information Credentials cache file '/tmp/krb5cc_1000' not found debug1: Unspecified GSS failure. Minor code may provide more information Credentials cache file '/tmp/krb5cc_1000' not found
I wonder why and what I can do to change it? Thanks and regards!
Ignacio's reply suggests me to "disable all GSS/Kerberos auth methods in your configuration."
/etc/ssh/ssh_config, do I have to make sure "no" is behind each of all options starting with "GSS": GSSAPIAuthentication, GSSAPIDelegateCredentials, GSSAPIKeyExchange, GSSAPITrustDNS, GSSAPIAuthentication, and GSSAPIDelegateCredentials?
Then what are the options for "Kerberos" auth method that I need to put "no" behind?
PS: following is the content of my local
/etc/ssh/ssh_config with commented options not copied to here:
Host * SendEnv LANG LC_* HashKnownHosts yes GSSAPIAuthentication yes GSSAPIDelegateCredentials no
