So, the question I have is why does it matter that the server wants to declare itself to the redirect as "a" but the redirector needs to use "b" when redirecting a client. I know, "for some reason" but that doesn't really tell me what the issue is here so I can't offer another solution without more information.AndyOn Tue, 26 Jul 2022, Yvan CALAS wrote:> Dear XRootD devs,>> I actually have a single XRootD server with two network interfaces and two different hostnames as follow:>> xrDxxx -> 134.xxx.yyy.zzz> xrTxxx -> 193.ttt.uuu.vvv>> The command `hostname -f` returns xrTxxx (so the IP address corresponding to 193.ttt.uuu.vvv).>> With this configuration, the XRootD server declares itself to the redirector as xrTxxx:>> 220725 16:19:44 32215 Protocol: server.616532:26@xrTxxx:1095 system ID: s-alicet1@xrTxxx 4448myredirector> =====> Routing for xrTxxx: local pub4 prv4 pub6 prv6> =====> Route all4: xrTxxx Dest=[::193.ttt.uuu.vvv]:1095> =====> Route all6: xrTxxx Dest=[2001:660:-----]:1095>> For some reason, I would like to change the server hostname from xrTxxx to xrDxxx. By doing this, the server then declares itself to the redirector as xrDxxx but it is not what I want to obtain. The redirector should still see the server as xrTxxx (all the clients must establish a connection with the server with the IP address 193.ttt.uuu.vvv).>> Is there a way to achieve this ?>> Thanks,>> Yvan>> ########################################################################> Use REPLY-ALL to reply to list>> To unsubscribe from the XROOTD-L list, click the following link:> https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=XROOTD-L&A=1>########################################################################Use REPLY-ALL to reply to listTo unsubscribe from the XROOTD-L list, click the following link:https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=XROOTD-L&A=1 ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the XROOTD-L list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=XROOTD-L&A=1
