B Troubleshooting
Authentication
SSH key authentication is not configured when a system is discovered for the first time.
SSH configuration for Linux and HP-UX systems:
Procedure B-1 SSH configuration for Linux and HP-UX systems
1. On the HP-UX system being managed, edit the following file:
/opt/ssh/etc/sshd_config
On the Linux system being managed, edit the following file:
/etc/ssh/sshd_config~
2. Search for the following line:
KerberosAuthentication yes
3. Edit the line as follows:
KerberosAuthentication no
4. Restart the sshd process.
-------------------------------------------------------------
On a Linux or ESX system, you might receive the following error when running the mxagentconfig
command or through Configure or Repair Agents:
Configuration failed to complete due to the following exception: Could
not access the file or directory sshd_config.orig on the target system
esxhost1. Remote system reported following error message: Permission
denied. Check whether the directory or file exists or whether the user
has the operating system permission to access it.
Solution:You must manually change the permissions in the file to 644.
Browser
If you are using a Firefox browser, you should avoid remaining on the Task Results page for an
extended period of time. If you notice the browser becoming sluggish while viewing the Task
Results
page, you should sign out of HP SIM to allow the browser to release memory. You can
then sign back in.

My Browser is displaying an error message Communication with the HP SIM server
has been lost
.
Solution: The HP SIM portal relies on the CMS to respond quickly to all requests.
• If the CMS is slow to respond to one request, browser performance can fall significantly during
that time.
• If the CMS is slow to respond to two requests, the browser appears to lock up completely
during subsequent interaction; the browser does not send additional requests until there are
fewer than two outstanding requests.
• If four sequential ping-like requests takes more than 30 seconds each to complete, due either
to request queuing or slow CMS response, the browser displays the message, Communication
with the HP SIM server has been lost
, even though the CMS might still be
responsive to other browser sessions.
By default, web browsers are limited to two simultaneous connections to a single web server. If
two requests are outstanding, any additional requests wait until one of the current connections
completes. This is by design and is in agreement with the HTTP 1.1 specification. The HP SIM UI
generates many requests, many of them simultaneously. The HP SIM portal relies on the CMS to
respond quickly to all requests. On a LAN, the browser receives a CMS response to most requests
