CHANNEL SIZE.

Recently I updated to Hardy Heron(Ubuntu beta) and with it cam
openssh-client 4.7p1. In my environment we have alot of
Extreme([url]www.extremenetworks.com[/url]) switch devices which we access via
ssh.

4.7p1 would no longer allow me to connect to the switches, however 4.6p1
would. The error I received was.

' channel 0: open failed: resource shortage: Channel open failed'

I did some diggin and noticed these two constants where changed between
4.6 and 4.7

#define CHAN_SES_WINDOW_DEFAULT (4*CHAN_SES_PACKET_DEFAULT)
#define CHAN_TCP_WINDOW_DEFAULT (4*CHAN_TCP_PACKET_DEFAULT)

Changing the new value of 64*, back to 4*, solved the issue.

[channels.h]
increase default channel windows; ok djm


Its probably an issue with our switches, but that is something I
probably cannot get rectified.
