The version of sshd in FreeBSD 8.4 is not backward compatible with older version from 8.3. OpenSSH_5.4p1 (on FreeBSD 8.3) OpenSSH_6.1p1 (on FreeBSD 8.4) # sshd -t /etc/ssh/sshd_config line 19: Missing argument. On line 19, there is: VersionAddendum It was OK in older versions. It will remove any default text appended to SSH protocol banner (for example 'FreeBSD-20120901'). On FreeBSD 8.4, there must be some string (any single character) I was really badly surprised that the machine was re-booted without ssh access! I think this...

Hello all, We got a report [1], that we miss "p1" suffix in the sshd identification strings in Fedora. I dig in and found out that it is also missing from portable usptream since 2004, when you were rewriting version.h header file with this information. Debian somehow patched this information back during the time in some places (ssh_api.c is missing). It does not look like

Hi, sorry if it is the wrong approuch to suggest improvments to OpenSSH, but here comes my suggestion: I recently stumbled upon the scponly shell which in it's chroot:ed form is an ideal solution when you want to share some files with people you trust more or less. The problem is, if you use the scponlyc as shell, port forwarding is still allowed. This can of course be dissallowed in

...f openssh in our distributions I came up with some problems that are also applicable to upstream so I took time to report them here. Found issues: * UsePAM option is written in integer format, instead of yes/no format * StreamLocalBindMask is not written * AllowAgentForwarding is not written * VersionAddendum is written, but even without value which makes it invalid option when using output again as input sshd_config * AuthenticationMethods is written even if it is empty which causes the same problem like the previous option These issues can be resolved using attached patch. Comments are welcomed....

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
