Alpine 2.00 (BSF 1167 2008-08-23) |
I tried with, on my target machine (macos):
# vi /etc/ssh/sshd_config
and set (instead of sending no messages)
ClientAliveInterval 15
then did a
# /etc/rc.d/sshd reload
and tried again:
address@hidden ~]$ /usr/local/bin/rdiff-backup macos-backup::/var
/home/backup/macos/var
Previous backup seems to have failed, regressing destination now.
but after 3-4 minutes I get:
Read from remote host macos.cmi.ua.ac.be: Connection reset by peer
Fatal Error: Lost connection to the remote system
(the same error as before)
what is wrong and how to remedy ?

Hi,
both on the backup and target machine my /etc/ssh/sshd_config has:
#TCPKeepAlive yes
#ClientAliveInterval 0
#ClientAliveCountMax 3
The manual says TCPKeepAlive is default yes. So I don't understand why the
connection still dies ?
If I want to use ClientAliveInterval and ClientAliveCountMax, these would have
to be changed on the target machine? would ClientAliveInterval 15
ClientAliveCountMax 3
be a reasonable choice? this would send out every 15 seconds after no data has
been received
from the client a request of a response from the client and try that
3 times?
Is that correct?
Can these settings for the ssh connection used by rdiff-backup been set
somewhere on the command line that I have in targetmachine's
/root/.ssh/authorized_keys2 ?
now it has:
command="rdiff-backup --server --restrict-read-only
/",from="<mybackupmachine>",no-port-forwarding,no-X11-forwarding,no-pty ssh-rsa
AA ... vQ== backup@<mybackupmachine>
(this would leave the 'general' settings of sshd_config intact)

Do you have TCPKeepAlive turned on in your /etc/ssh/sshd_config (or
appropriate config file)? And if so, have you toyed with the
ClientAliveInterval and ClientAliveCountMax intervals? See
http://www.openssh.com/faq.html#2.12 for a quick reference.

Seems the SSH connection gets lost..
How can one remedy to this (rdiff-backup paramters, ssh parameters ???)
