Here is a brief guide about "How to install SSLexplorer on SUSE Linux". Once you download a package of SSLexplorer or digging websites, you could find well-documented guide. However, I am put some notes here that was missing from the documentation. I hope this information is informative for you and we would like to thank you for viewing.

Before start to install SSL explorer, there are two important notes.

- Java JRE 5.0 installation guide

- SSL Explorer quick installation guide (It comes with SSL Explorer package)

You need to install JRE 5.0 frist. Do not try JRE 6.0 yet. It support only Solaris at this time.

To verify that you package has already installed JRE, try below command. If you see below output, already JRE had installed. So, skip JRE install procedure.

vpn:/tmp # java -version
java version "1.5.0_15"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_15-b04)
Java HotSpot(TM) Client VM (build 1.5.0_15-b04, mixed mode)

Thru last week, I had installed and tested a network management system is called

Centreon install - invalid user error message
"Centreon". Honestly, it was a bit complicated than I thought. However, I found a well documented installation guide from Centreon website. It saves a lot of my time. Here is the link you might need it if you want to try Centreon Network monitoring tool.


Few errors popped up as usual while it was installed. Most of errors was files and directory location related. Use find or locate command to find right path or application is installed.

About 25 minutes spent to complete installation of Centreon. First page was nice and pretty. Tried first time login, message "Invalid user" I thought I was so excited enough to mis-typed admin passwords, but ... kept getting same massage.

Well, I am so sure that I got right login and password to access Centreon. Started googling......

See below to see the issue.

Traceroute(on window system, command will be "Tracert") is a most common and essential troubleshooting tool for network administrators. Even normal users who are facing some routing, latency or packet lost issue would be familiar with this tool. On DOS prompt, 'tracert' command syntax is "tracert hostname or IP address x.x.x.x". For example, "tracert cisconet.com" from my location today and the output might look like below:


C:\>tracert www.cisconet.com

Tracing route to cisconet.com []

Don't know why putty.exe doesn't provide easy way to handle configuration file and settings. Well, I guess there are some reasonable reason for developer, but it is definitely troublesome to transfer configuration and setting. Especially, if you have a lot of sessions that is pre-configured as network admin. Transferring configuration is only one complaint for me. However, there are way to transfer setting , so do not complain it unless you have donated some bucks.

See below procedure to complete migrating your configuration and setting. Basically, exporting and merging a s/w registry of putty.exe.

Same program file will be used on both server and client location. Default value is shown 10sec runing time and it used 5001/tcp port. Be careful to use this, it will suck all the bandwidth.
