Hello, My usage of ProxyCommand just calls the nc utility with various parameters. That in turn after the initial setup just copies copies the data from the network socket to stdin/stdout. This useless coping can be avoided if ssh has an option to receive the socket from the proxy command. I suppose it can improve network error reporting as ssh would talk directly to the network socket rather

...pulated network. Naturally, I set up Samba and added WINS as a name resolution option. I found out that some programs now can use NetBIOS names, other can't. openssh falls into latter category :-( I found that openssh use this snippet to convert hostname to ip: if((gaierr = getaddrinfo(host, strport, &hints, &aitop)) != 0) fatal("%s: %.100s: %s", __progname, host, gai_strerror(gaierr)); and it fails for me exactly in this if() when I say "ssh <wins_name>".

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

I was wondering what everyone's thoughts were on a simpler way to exclude addresses from having listeners on them. I know a lot of people have multiple subnets, especially larger corporations. Some networks are non-route-able, and therefor unsuitable for use with SSH, aside from communication between other servers on the same subnet. Given that we may want to exclude those non-route-able
