Hi all, I install Xen 4.0.1 step by step according to the installation of Xen 4.0.1. I can create Para domU and use console to access it, but I can not use ssh to domU. When I use ssh to link the domU, I can not access the tty of domU after inputting password. I did not why like this? Actually, xvc0 is fine. Do anyone meet this situation and can you give me a solution?

I check my sshd configuration, it is the same as dom0, I can use ssh to access domU, but can not use ssh to access domU. 2013/7/8 Wei Liu <wei.liu2@citrix.com>> On Mon, Jul 08, 2013 at 08:51:35PM +0800, xiao ling wrote: > > Hi all, > > > > I install Xen 4.0.1 step by step according to the installation of Xen > > 4.0.1.

Hello, Xiao. I must agree with Wei, it seems like some OS level issue, not related to Xen.

I did not why like this?As I understand, a SSH client does prompts you for password. It means that the low level bidirectional TCP connection was established, so the networking and firewall configuration must be fine.> Actually, xvc0 is fine. Do anyone meet this situation and can you give > me a solution?I suggest you 2 measures: 1. Check your DomU logs for any messages, that appear in the same time: when a SSH connection is attempted. Find thm under /var/log; messages, syslog, auth.log, daemon.log. 2. Give your connection some time, just wait up to a minute. It happens that SSHd tries to log the connection using reverse host name resolution of the client, not it''s IP. If your DNS server is slow or unable to answer, SSHd waits a while before giving up. If this does not help to solve the issue, the indicated place to ask about it is a forum or mailing list specialized on your DomU Linux distribution (CentOS? Ubunut?).
