It prints the error message, because this in fact is an invalid IPv6 address. You should have returned [2001:948:40:2:0:0:0:149]:1094 > When testing xrdfs against an xrootd daemon over IPv6, the answer is a > bit sad: > Sw[::193.166.0.114]:1094 = the machine handshakes over IPv6, then > switches to IPv4 for everything else. Most of the requests handled by xrdfs either redirect or use locate queries and the client goes to a host it is pointed to. It switched to IPv4 because the server told it to do so. Good for you.
