RE: ssh session hangs when term is flooded with text.

2006-03-31 Thread fbsd_user 

There is a patch to OpenSSH to fix the buffer size problem caused by
the different operating systems OpenSSH runs on.  When the host and
remote are different operating systems the send/receive buffer sizes
do not match and this causes drastic slow down. Like in using Winscp
client connecting to a FreeBSD box or Linux box.

ports/security/hpn-ssh/

contains the patch code to fix this problem in sshd/ssh.

Subject: ssh session hangs when term is flooded with text.


When I log into any FreeBSD box through the VPN (IPsec site-to-site)
my ssh session will eventually hang when a large amount of text/data
is displayed, for example compiler output, running top, running
links
or lynx, etc. Obviously this is a networking problem but I'm not
sure
where to start.

1) Look at the state of the sshd task handling your shell.
2) Look at the network traffic for the sshd session.
