 If we cannot find the exact application name for centos, say MATLAB
 for centos does not exist, so we must search for 'Mathematics
 laboratory for centos' ? Or if Pspice for centos does not exist so we
 must search for 'Electronics circuit schematics editor and simulator
 for centos' ? If there any reference site that we can select centos
 application with respect to their functionality deffinition but not
 just the application name?

Not very much software is Centos-specific, but anything that runs on Red Hat 
Enterprise versions should work on the corresponding Centos version, including 
the things in third party 'EL' rpm repositories and commercial products (like 
Matlab...).

The biggest searchable, up to date collection of open source software project 
descriptions is probably http://freshmeat.net, but once you locate an 
interesting project you might want to see if you can find an RPM-packaged 
version at EPEL, rpmforge, etc. for easy installation and updates instead of 
trying to build from source yourself.

And you might like 'R' as an alternative to octave or matlab.

Re: [CentOS] svn check out failed for 'connection refused' reason

2011-07-19 Thread Steve liu 
yes, port level block I think. see below.

===
nc -v svn.mplayerhq.hu 3690
nc: connect to svn.mplayerhq.hu port 3690 (tcp) failed: Connection timed out
nc -v svn.mplayerhq.hu 80
Connection to svn.mplayerhq.hu 80 port [tcp/http] succeeded!
===
I'll try to contact our IT to solve this, thanks

 Do an nmap scan on svn.mplayerhq.hu.  Look for svn / subversion in etc
 services to see which port you specifically need to have open.  I'd bet your
 upstream firewall is blocking the port.  You can try connection to the host
 + port with nc -w2 -v to see if you get connected.  Type some junk and you
 should see some error back from the server.
 If the network looks good with all of the above, the problem is with your
 local svn binary, or its configuration.
