[tigerste@usva bin]$ ./xrdcp
xroot://bunsen-ipv6.ndgf.org/ipv6/100MB_test_pic testpic
[100MB/100MB][100%][==================================================][3.03MB/s]
[tigerste@usva bin]$ ./xrdcp
root://[2001:948:40:2::149]/ipv6/100MB_test_pic testpic2
[100MB/100MB][100%][==================================================][3.125MB/s]
[tigerste@usva bin]$ pwd
/home/tigerste/xrootd/install400rc3/bin
