[Capistrano] Re: Errno::ECONNRESE when a command takes a long time to run

[Jamis Buck]

Networking is not my forte. Net::SSH does not currently support either TCPKeepAlive or TCP_NODELAY, primarily because I have no idea how to implement or test those. If someone wants to take a stab at it, it could be a valuable addition to Net::SSH.

Thanks Kenneth,

This is nice, but I fail to see the relevance for Capistrano.  Can we
set TCPKeepAlive and TCP_NODELAY in Net::SSH?  Because that's what
seems to be needed here.

Thanks!

This happens while running commands remotely that take a "long" time
to execute.  Something on the order of minutes (restoring backups or
filling an EC2 volume for example).  This is on Ubuntu Hardy 8.04
using OpenSSH_4.7p1 Debian-8ubuntu1.2, OpenSSL 0.9.8g 19 Oct 2007.

BTW, I do get kicked out of the machine regularly when I simply SSH

specific.

into the box and run the same commands, so this is nothing Capistrano-

Any help would be *very* appreciated!

future.

Now I wish I was skilled enough to dive into net/ssh, maybe in the near Jamis, I'm sure the SSH protocol has a NOOP similair to FTP. I based this only on being able to set it in putty and SecureCRT. I did q quick google and found this (http://drupal.star.bnl.gov/STAR/comp/sofi/facility-access/ssh-stable-con ), where there is a reference made to some RFC. They also discuss parameters for the *nix ssh command that can be used as well, this will help Francois

as well.

Best
