SSLexplorer is one of awesome VPN software that is even opensource. For most of users who don't want to spend extra money for security. This solution would be the best. Yes, security is expensive.
Okay here is what I want to talk about this article, login failure with message "invalid credentials". What the~

Actually it was minor minor setting problem. I had installed non-enterprise sslexplorer version on SUSE(OpenSUSE 10.3). At first login, it kept on failing to access. Am I forgetting superuser login/pwd already ? no wonder!

I reinstalled sslexplorer twice and I realized it is caused from something else.
spend few min and found a problem.

You need to change two things.

1. Edit HOST Server:/opt/sslexplorer/conf/wrapper.conf and add few line below

-Dfile.encoding=UTF-8

ex) On my file, wrapper.java.additional.1 is already defined as shown below

# Jetty Paranoid setting
wrapper.java.additional.1=-Dorg.mortbay.http.Version.paranoid=true

add this portion below after "# Jetty Paranoid setting" statement

#wrapper.java.additional.1=
wrapper.java.additional.2=-Dsun.jnu.encoding=UTF-8
wrapper.java.additional.3=-Dfile.encoding=UTF-8

2. Edit HOST Server:/opt/sslexplorer/conf/system.properties and add the line

file.encoding=UTF-8

Now, restart sslexplorer.

sslexplorer_server:/opt/sslexplorer/service sslexploere start

It should take care of your login issue. I hope this is informative for you.

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
http://java.sun.com/products/archive/j2se/5.0_04/jre/install-linux.html

- 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)

Wake on LAN extention for SSL explorer

It is nice to have an extension for Wake on LAN. You can save some electric cost to control workstations and devices that are not used all the time. Of course the devices should support WOL function.

I found an extention from web(googling) and linked below.

Download Wake on lan for linux client
(ATTN: I just provide a link to download)

How it works? Basically, script sending(broadcast) magic frame on the same broadcast domain. Workstation that is enable Wake on LAN function monitoring the magic frame. When they have received it, it wake the machine up.

How the frame looks like?

FFFFFFFFFFFF + at least 16 times of MAC address that you want to wake up.

ex) MAC 00:14:D1:14:C7:B2

FFFFFFFFFFFF0014D114C7B20014D114C7B20014D114C7B20014D114C7B2
0014D114C7B20014D114C7B20014D114C7B20014D114C7B20014D114C7B2
0014D114C7B20014D114C7B20014D114C7B20014D114C7B20014D114C7B2
0014D114C7B20014D114C7B2

Now, go to SSL explorer and add the extension

1. Download WOL extention and save a directory where you know well.

2. Click 'Extention Manager' from SSLexplorer (left side)

3. Click 'Upload Extension'

4. Browse the WOL extension and open it

5. Highlight the extension from the a folder where you saved the extension

6. Click 'upload'

7. Now, you can see new installed extension 'Wake-On-Lan Client for Windows

8. Let's Create Application Shortcut. Click 'Applications' on Resources menu.

9. Click 'Create Application Shortcut'

10. Choose 'Wake-On-Lan Client for Windows

11. Provide a name and description

12. Provide MAC and Host IP address as 255.255.255.255.

o Do not put target host's IP address.
o Common mistake, do not put IP address of your machine that you want to wake up. You need to send broadcast packet/frame
o Default value is 9(UDP), make sure incase your firewall is not blocking it

13. Add users

14. Done. New installed shortcut icon will be shown at screen.

Now, you can save some energy and $$$ here !
