ECLIPSE 4.1.0; 4.1.1; Indigo - install / update plugins cannot connect to sites - cannot connect to SVN repo with Subclipse

Question

Need help figuring out why I keep getting the following error:

permission denied: connect Unable to read repository at http://update1.aptana.org/rails/1.2.1.23268/content.xml. 

Permission denied: connect

Mostly for all my installed plugins. I tried to upgrade or install the latest Subclipse plug-in since I cannot connect to my repository (even the one that I knew worked before - and the SVN-url works elsewhere, for example, with TortoiseSVN).

 svn: Cannot connect to 'svn+ssh://kosh.nku.edu': There was a problem while connecting to kosh.nku.edu:22 svn: Cannot connect to 'svn+ssh://kosh.nku.edu': There was a problem while connecting to kosh.nku.edu:22 There was a problem while connecting to kosh.nku.edu:22 Permission denied: connect 

I switched the interface to SVNkit - which solved the problem earlier.

I feel the two questions are somehow related? I definitely turned off the firewall and didn't change anything.

I'm on a Windows 7 laptop, just using my home internet.

Any ideas or help would be appreciated.

Answer 1

..... "adding '-Djava.net.preferIPv4Stack = true' to eclipse.ini under -VMARGS:

 openFile -vmargs -Djava.net.preferIPv4Stack=true 

An alternative is to run Eclipse under 1.6 jvm by adding

 -vm C:/Program Files/Java/jre6/bin/javaw.exe 

above -VMARGS. "

- it worked for me. found here: http://www.java.net/node/703177 I am using JDK 7

Answer 2

I ran into the same problem and solved:

"adding '-Djava.net.preferIPv4Stack = true' to eclipse.ini under -VMARGS: After the change, the ini file looks like this:

... open the file -vmargs -Djava.net.preferIPv4Stack = true ...

Answer 3

I had a similar problem with Android SDK and Eclipse 3.7.2. Android SDK said: "permission denied: connect." Eclipse failed on a blue screen. My laptop is running Windows Vista and is protected by Dr.Web Security Space.

Consulting with "-Djava.net.preferIPv4Stack = true" and "Window -> Preference -> General -> Network Connection -> select Direct" did not help.

The problem was resolved by installing the latest antivirus without a firewall.

Answer 4

After upgrading to Windows 8, I found that many of the programs in the toolbar, etc. not configured to run as administrator. Although this does not seem to have affected Windows 7 (perhaps because I started unpacking from the command line in the cmd admin window), now this is happening.

I had the problem described in this thread because WinRAR used to unpack the downloaded zip file did not start as an administrator, so the installation was not configured correctly. After uninstalling the eclipse installation and using the property / shortcut / advanced to set Run as administrator on the WinRAR startup icon, then running it and selecting the zip zip download and extracting it, I was able to access the Eclipse and Android update sites without any problem. What threw me into the loop was I was running Oracle Java 6 JDK 1.6.0.38, so preferIPv4Stack didn't seem to be applied.

I hope this alternative gives an idea to others where a problem with IPv4 does not help.
