Dear CentOS people,
I'm sure many have faced this before but I can't seem to figure this
out.
I need unattended OpenSSH and its SFTP connections to be closed after a
while (say, in 10 minutes). This needs to override anything that could
be done from the client side (ServerAliveInterval or keepalives a
program like PuTTY can send). I kind of understand it's not always
easy to know when the client side is "unattended," but I'd like to know
where people drew the line and what people did in the past.
ClientAliveInterval only seem to help reap connections when the client
side is unreachable, so this doesn't really help.
TMOUT in shell achieves what I want with SSH, but this doesn't help
with SFTP. Setting net.ipv4.tcp_keepalive_probes to 0 kind of does
what I want (ServerAliveInterval ruins it), and I'm not sure if that's
generally accepted practice.
If this could be achieved in OpenSSH, that would be great, but if it
needs to be some other way I'll be glad to find out...
Your insight appreciated,
