I tried doing this from yakut. IT has the same error. If I load the
libNetx.so library it is a bit better but still an error;
root [12] TXNetFile
t("root://glast01//nfs/farm/g/glast/u07/mcenery/systests/G$
Error in <TUnixSystem::GetServiceByName>: no service "rootd" with protocol
"tcp"
Error: t already declared as different type. ~TXNetFile() called
FILE:(tmpfile) LINE:1
*** Interpreter error recovered ***
I see similar errors with BaBar tools;
[yakut05] ~/reldirs/tstanalysis-24/workdir > KanFileUtil

2005-02-26 11:38:37 11922 Err : TUnixSystem::GetServiceByName - no
service "rootd" with protocol "tcp"
Is this something that needs to be configured?

What does the "matching protocol not found" mean in the xrootd log file? What protocol is it talking about - perhaps an authentication protocol that I need to configure?
