Description Marek Grac 2009-06-19 11:04:31 UTC 
+++ This bug was initially created as a clone of Bug #496446 +++

Description of problem:
At least with IBM's RSA, you can easily change the default ports of SSH and Telnet services. The agents should accept an optional param specifying the port (or accept address in the form of address:port)

Version-Release number of selected component (if applicable):
ovirt1.0snap9

How reproducible:
Always

Steps to Reproduce:

Moving this to be in next version of RHEVH.  If this is a strict requirement for 1.0 release we'll need to get PM approval to add this as an exception.

--- Additional comment from mgrac on 2009-06-15 09:38:09 EDT ---

Using address:port can be problem with ipv6 and we already have separate option 'udpport' for some agents.

--- Additional comment from fdinitto on 2009-06-16 01:38:30 EDT ---

maybe we can standardize on --port or --ipport or --tcpport. Afterall ssh and telnet don't use udp...

--- Additional comment from mgrac on 2009-06-18 04:18:33 EDT ---

port is already used (plug number)
--ipport looks ok for me 

imho udpport is already used also for tcp

Comment 9 Jaroslav Kortus 2010-03-11 16:58:06 UTC 
The fencing agents seem to accept new -u option and ipport STDIN parameter. The connection is made to the port specified.

However, none of the manpages was updated to reflect this change. "-u" option and the STDIN parameter "ipport" should be described in each agent's manpage.
Comment 10 Jaroslav Kortus 2010-03-11 17:14:36 UTC 
fence_wti -u 54444 -a 1.1.1.1 -n 44

this still connects to port 23, so not all fencing agents are handling the new options correctly.
