This bug has been fixed in Release 2011a (R2011a). For previous product releases, read below for any possible workarounds:
This issue is a bug in Java on Debian with ipv6 settings. When the net.ipv6.bindv6only is set to 1, networking is broken for Java. For more details about this bug, see the report here:
To check this setting you can run the following command:
sudo /sbin/sysctl net.ipv6.bindv6only
If the output of the command is "net.ipv6.bindv6only=1", you can temporarily change it by running:
sudo /sbin/sysctl net.ipv6.bindv6only=0
For a persistent fix, run the command:
sudo sed -i 's/net.ipv6.bindv6only\ =\ 1/net.ipv6.bindv6only\ =\ 0/' \
/etc/sysctl.d/bindv6only.conf && sudo invoke-rc.d procps restart
In either case, once complete, restart MATLAB to enable the changes. Once MATLAB is restarted, you should be able to use matlabpool once more.
