That URL is dead now too. Here's yet another one: <>.

Also, #2619 was a duplicate of this.

I've been running into this problem lately. Here's a concrete reason to support a more up-to-date version of the protocol. Conch supports version 3, from draft -02 of the filexfer protocol. Draft -03 (protocol version 4) introduces the type field of file attributes. Without that field, it's not possible to portably determine whether a remote file is a file, directory, or whatever — POSIX specifies the existence of the field, but not its values. (In practice, UNIX-derived systems all seem to use the same values for the most common types, but that's thin ice.)

The file transfer protocol's current version is draft -13, from 2006, describing protocol version 6.
