SupportProblem RFIO commands such as rfcp don't work on a freshly-installed SLC4 machine
SupportAnswer (see CASTOR FAQ No.10).

Check the firewall configuration (in /etc/sysconfig/iptables) for a line like 

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 30000:30101 -j ACCEPT
before the first line that ends with REJECT, and if missing, add it. If you modify the file, please run /sbin/service iptables restart afterwards to activate the changes.

Background: RFIO needs to be able to receive callbacks from the server(s), and the client command will wait for this callback on one of these ports. The CASTOR RPMSs usually take care of adding these ports, but this mechanism does not work on a freshly-installed machine where CASTOR was part of the initially-installed RPMs. Another workaround is to reinstall, upgrade or downgrade the castor-lib RPM - the exact version doesn't matter, but the included postinstall script will do the above modification..
