Don't forget about the rat control port of 47000/udp. That always has to be open as well. To avoid networking issues I usually tell people to open up 41000-65535 udp. I know its a large range, but going from room to room, venue to venue, you will never know what udp ports are used. -- Jeremy Mann jer...@biochem.uthscsa.edu University of Texas Health Science Center Bioinformatics Core Facility http://www.bioinformatics.uthscsa.edu Phone: (210) 567-2672
