Linux: Login with non-root user using ssh

Hi!
The other day, I was working with a Linux server in which I was unable to login, using ssh, as any non-root user.
I'm not sure that this is the more correct way to do it but, for temporary workaround, I have edited the /etc/ssh/sshd_config file and changed the following property:

    usePAM no

And after restarting the ssh service, using the command service sshd restart, I was able to login in the server as a non-root user.
If anyone have another solution for this problem, please share it!!!

Thanks.

Installing Firefox 5 in a Red Hat machine

Hello!
While installing some IBM software, the installer launchpad failed because it required Firefox 3.5 or later. So, to solve the problem, I had to install a newer Firefox version on the server.

Here are the steps to install Firefox 5 in Linux, which I've found in the following link (http://linuxforums.org.uk/netbooks/install-firefox-5-on-an-acer-aspire-one-running-linpus-lite-linux/):

• sudo mv -v /opt/firefox /opt/firefox-backup
• wget -O firefox-5.0.tar.bz2 "http://download.mozilla.org/?product=firefox-5.0&os=linux&lang=en-GB"
• sudo tar -jxvf firefox-5.0.tar.bz2 --directory /opt
• sudo mkdir /opt/firefox/plugins
• sudo ln -fs /opt/firefox/firefox /usr/bin/firefox
• sudo ln -s /usr/lib/mozilla/plugins/* /opt/firefox/plugins
• wget http://dl.dropbox.com/u/11876059/libstdc++6.tar.bz2
• sudo tar -jxvf libstdc++6.tar.bz2 --directory /opt/firefox
• firefox -profilemanager -no-remote

Perfect!!! Now firefox 5 is already installed and the installer launchpad already runs as expected.

How to suppress SIP registration failures in the Sametime 8.5x client

I knew that this were somewhere, but I could not found it.... Next time, I'll know where to find it :-)

https://www-304.ibm.com/support/docview.wss?uid=swg21456002

Problem

When the Sametime client fails to connect to the Media Server there is a pop-up such as the following: "Unable to initialize Computer, and it can't be used at this time.

com.ibm.collaboration.realtime.telephony.softphone.SIPPhoneException:
Processed unsuccessful response: SIP/2.0 401 Unauthorized"


Can this be suppressed?

Resolving the problem

You can add this line in the Sametime plugin_customization.ini file to suppress this pop-up.
