Re: [gftp] Settings question

[Brian Masney <masneyb@gftp.org>]

Yes, download the gftp 2.0.16 source code and edit lib/sshv2.c and around line
241, you will see this:

  sshv2_add_exec_args (&logstr, &logstr_len, &args, &args_len, &args_cur,
                       " -e none");

Remove it entirely and then recompile. With this option off, you will be able to
connect and transfer files, but you will eventually run into problems with file
transfers stalling.

I still don't see what this option is hurting. If you are getting the "Error:
Message size 1483499874 too big from server" message when you connect, then your
sftp-server binary is not in your path. gftp has an option to specify the
sftp-server path on the remote server. You can even specify a different path on
a per bookmark basis.
