I've got two VMs with
arch linux and
debian (running under
virtual box). Not long ago, it started to take a lot of time connecting to
arch VM over
ssh. The first time after a while, successive attempts happen quickly. Here's what I see in the
debug1: userauth-request for user yuri service ssh-connection method none debug1: attempt 0 failures 0 debug3: Trying to reverse map address 10.0.2.2. # ^^^ spends a lot of time after this line debug2: parse_server_config: config reprocess config len 314 debug2: input_userauth_request: setting up authctxt for yuri debug1: PAM: initializing for "yuri" debug1: PAM: setting PAM_RHOST to "10.0.2.2" debug1: PAM: setting PAM_TTY to "ssh" debug2: input_userauth_request: try method none Failed none for yuri from 10.0.2.2 port 35786 ssh2
10.0.2.2 is the default gateway for the VMs. What does this all mean?
P.S. Here's a good answer, thanks to which I was able to make some progress in researching the issue.
