Hello OpenSSH folks, This was a really minor knit, but I noted while I was developing a pexpect module for ssh that setting ConnectTimeout to 0 in the options to ssh sets the login timeout to infinite time. I was wondering whether or not this was a documentation bug and/or potential clarification that could to be made, or if this was a software bug that needs to be fixed. I don't see

Hello! I'm hoping that Gmail won't HTML format this mail so that I'll get flamed :) Anyway, my question relates to ssh_config. The problem I find is that the Host pattern is only applied to the argument given on the command line, as outlined in the man page: "The host is the hostname argument given on the command line (i.e. the name is not converted to a canonicalized host name
