Choosing A Webhost:
A web hosting service is a type of Internet hosting service that allows individuals and organizations to provide their own website accessible via the World Wide Web. Web hosts are companies that provide space on a server they own for use by their clients as well as providing Internet connectivity, typically in a data center. Web hosts can also provide data center space and connectivity to the Internet for servers they do not own to be located in their data center, called colocation. more...

Re: Java apps can't use network: msg#00137

Subject: Re: Java apps can't use network

Hi,

I tried running some Java apps on Fedora Core 4 with SELinux enabled and they can't connect to network. The symptoms are strange (at least for me, I'm new to SELinux): 1) I use TARGETED policy - I thought it shouldn't restrict applications unless they were explicitly listed? 2) I tried setting SELINUX to PERMISSIVE - the apps still couldn't use network. 3) The apps are blocked silently - no info in syslog, regardless of SELINUX mode.

All non-Java apps can use the network. All non-network related Java functions seem to work just fine. I tried 2 versions of Sun JRE.

Am I doing something wrong or is it a bug? Can I use my Java software without totally disabling SELinux?

Regards,

Igor Wawrzyniak

which java app?
when it still does not work in permissive mode than it isn't an selinux issue.
might be a firewall/nat problem which ports are this apps trying to use?
