When you receive the following error, while starting ASDM:
ASDM Error: Unconnected socket not implemented
You should look at your Java versions. When you are using Java 6 Update 10 or higher and ASDM 6.1.5 or lower, you will receive this error. There are two workarounds for this problem:
- Downgrade Java to Java 6 Update 7 or lower;
- Upgrade ASDM software;
Cisco released an Interim Release (188.8.131.52), which resolves the problem above.
