Net::OpenSSH communicates with the OpenSSH master process through a socket that by default has a name similar to
/home/user/.libnet-openssh-perl/my.host.name.com-4589-445. The maximum length for the path is given by the size of the
sun_path slot on the
sockaddr_un structure, which seems to be 92 bytes for HP-UX.
So, your home has a very long path or you are accessing hosts with extremely long file names or both. As a workaround, you can set a shorter path passing it into the constructor with the option ctl_path.
In any case, the module shouldn't fail just because the hostname is too long. This is a bug I will fix in the next release.
Update: version 0.75_01 is now available!
