When executed, the command above only display the error I mentionned
(unable to connect). If I add --debug-file to the command line, the file
id creates is empty.
I also tried by re-enabeling telnet instead of ssh, and I got the same
result, except that now the debug file looks like :
--------------------
telnet> set binary
Negotiating binary mode with remote host.
telnet> open 1.1.1.1 -23
Trying 1.1.1.1...
Connected to 1.1.1.1.
Escape character is '^]'.
User Name : user
Password
--------------------
I replaced username and ip with fake ones.
Regards,
If response is too fast then problem is in connecting information/process.
If it took long enough (timeout problem) then it can be problem with
change in command prompt. If it is possible please send me what it is
displayed when you are trying to do it manually.
Response is indeed very fast when trying with the agent. With tcpdump on the
node I try with the agent, I see ssh packets go to and from the apc switch.
When ssh-iing to the apc switch, it takes about 2 or 3 seconds before I get
the password prompt, and then I see :
------------------------------
user@xxxxxxx's password:

apc>qConnection to 1.1.1.1 closed.
------------------------------
I think I have found the problem... Looking at fence_apc, I see :
options["ssh_options"] = "-1 -c blowfish"
Now, if I add this to my ssh command like so :
ssh -1 -c blowfish user@xxxxxxx
I get :
Protocol major versions differ: 1 vs. 2
So, there is no ssh version 1 on this version of the apc switrch. I
commented out that line in /usr/sbin/fence_apc, and now the fence agent is
able to establish the connection, but it cannot go any further.
The only thing that shows in my debug file is :

user@xxxxxxx's password:
