Hi, Since the ports were openned last week I thought I'd try to make the dCache SE the default for dteam. Unfortunately now I'm failing the SFTs due to third party copy problems. I can replictae the problems and think I've narrowed it down somewhat. Third party SE to SE copies work from other SEs on site but fail from ones offsite so I'm suspecting a firewall interaction problem. Poking around on the server whilst the copy attempts are going on I find port 20000 listening with (according to lsof) java listening to it. [root@heplnx204 install]# lsof -i :20000 COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME java 4841 root 9u IPv4 19888 TCP *:20000 (LISTEN) [root@heplnx204 install]# ps -ef | grep 4841 root 4841 4840 1 17:48 ? 00:00:17 /usr/java/j2sdk1.4.2_08//bin/java -server -Xmx256m -XX:MaxDirectMemorySize=256m -Dorg.globus.tcp.port.range=50000,52000 -Dnetworkaddress.cache.ttl=600 dmg.cells.services.Domain gridftpdoorDomain -param setupFile=/opt/d-cache/config/gridftpdoorSetup ourHomeDir=/opt/d-cache The choice of port looks suspiciously like something trying to use the GLOBUS_TCP_PORT_RANGE but having the default value hardwired in. Does anyone have any ideas where I can look is anyone else running this on a non standard port range? Thanks, Chris.
