RE: [Xen-users] xe cli not working on remote machine

[<jfcouture@xxxxxxxxxxxxxx>]

Hi,

 

did you do a query with your XE on the gentoo box ?

 

the XE be it self does work but querying returns errors

 

I tried on a 32 bits version but it also failed.

 

I tried on a 64 bits Ubuntu 10.04 and it worked.

 

there's something different on the stunnel package but cant figure it out.

I just copied the xe-binary from my citrix-hosts, installed stunnel and
ran xe

Something like:

# emerge (-pv) stunnel && scp root@
$CITRIX-Box:/opt/xensource/bin/xe /usr/local/bin/

XE just runs fine on my debian-boxes, but never tried on a 64bit-Host...

is your gentoo-box amd64 or i386?

hth,
