Re: [Fab-user] Problem w/ some solaris hosts

[Jeff Forcier]

Hi Cesare,

Were you previously using Fabric 0.9.x, or would you be willing to
quickly test it out (note that it's not backwards compatible so you
may want to use a simple test case)? It would help to know if the
problem still occurs if all other factors are the same but Fabric is
0.9.x.

My guess, however, is that it's purely a Paramiko problem, in which
case  there's nothing we can do here and you would need to add a +1 on
the Launchpad ticket you linked to, and/or mail the Paramiko mailing
list.

Best,
Jeff
