The Solaris Systems are no longer available
All of you who had Solaris accounts have had those accounts moved to the Linux network. If you already had a Linux account, at least your mail and web settings have been moved. You can access this account via ssh/scp/sftp on the general-purpose Linux machines, listed above.
If you are used to using ftp (which is being phased out anyway), you should move to sftp instead. There is a command-line sftp program in most *nix installs, and it is supported by gftp (though it calls the protocol "SSH2").
