instance tty problem [closed]

Hi openstackers !

I can ssh my instance (linux) with putty (windows, sorry i do not have a choice :-).

Some commands works, other stuck/freeeze and I need to kill session (Ctrl-c doesn't work )

For example : $ sudo tail -f /var/log/messages works but $ sudo cat /var/log/messages freeze with no output

Under VNC, all is ok.

any idea ? Does putty needs a special configuration ?

Thanks a lot ! I lowered the MTU (1492 -> 400) and it works ;-)

I found another solution, is to configure dnsmasq with neutron : (

1400 seems to be good for mtu.
