Starting with changesets 8707 in my daily testing, I''ve been unable to
access guest domains via SSH or telnet.
http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=504
When I access the guest domains via ''xm console'', I am able to
ascertain that networking is up on them; I ping external machines, mount NFS
share, etc. However, I cannot ssh into them from external machines, or even from
dom0.
This is happening on all machines, SLES 9 SP2, RHEL 4, and FC3/4 based machines,
both x86 and x86_64.
Trying to SSH into guest domain from external machine:
dyn95341161:~ # ssh lamb5-vm1
Password:
-------------
No response or comeback from login.
Guest domains accessed via ''xm console''. You can see NFS mount
and ping response.
===lamb5-vm1:~ # df -T

All services are up on the guest domains. I tried to telnet into the guest
domain, and the following
message displays:
[root@thinkcentre-dom0 xen-unstable.hg]# telnet 9.53.41.223
Trying 9.53.41.223...
Connected to thinkcentre-domU-009053041223.austin.ibm.com (9.53.41.223).
Escape character is ''^]''.
telnetd: All network ports in use.
Connection closed by foreign host.
Has anyone else seen this problem?
