Hi Folks,
We've been using rsh, and rsync calling rsh, to transfer large files over local network links to avoid the encrypt/decrypt overhead. I know about the security concerns, but these transfers are completely local on isolated networks.
In preparation for deploying a 40GbE link I noticed that rsh isn't supported on Leap 15 and up. There's a replacement called mrsh that uses something called munge for authentication. Bummer. I'd rather not have to figure this all out when authentication isn't needed in the first place.
So, what are the options for sending many large files between machines without encryption?
SSH insists on encryption, but there are apparently patches that will allow it to be turned off.
Maybe wrap netcat up with some scripts?
Maybe rsync could be persuaded to use netcat?
Byte the bullet and learn munge?
Any other options? ftp
$ rpm -qf /usr/bin/ftp tnftp-20141104-5.1.x86_64 lftp-4.7.4-2.6.1.x86_64
Good point, I hadn't considered ftp. But the clients I've used are a bit cumbersome to use when transferring thousands of large files thither and yon. I've got spoiled users and they've gotten used to pre-placed ssh pubic keys. I'll take a look at your referenced clients, maybe they allow no-prompt logins to anonymous accounts?
Thanks, Lew
