Hi Michal, et al., As we discussed last week, in order to enhance the XrdAdaptor logging, we need some small developments on the XRootD side. I will summarize what needs to be done with some examples: # Requests 1. Get the actual hostname (or even the IP) instead of the DNS alias on the URL GetHostName() function [1]. ``` Traceroute: cms-xrd-global.cern.ch vs Traceroute: cms-xrd-global02.cern.ch $ nslookup cms-xrd-global.cern.ch Name: cms-xrd-global.cern.ch Address: 188.184.30.79 Name: cms-xrd-global.cern.ch Address: 188.184.29.87 Name: cms-xrd-global.cern.ch Address: 2001:1458:d00:2f::100:326 Name: cms-xrd-global.cern.ch Address: 2001:1458:201:e5::100:49 $ nslookup 188.184.30.79 79.30.184.188.in-addr.arpa name = cms-xrd-global02.cern.ch. ``` 2. Get the specific port where the connection has been established. With the URL GetPort() function, we get the service port (i.e. 1094) however we would like something like: ``` Traceroute: cms-xrd-global02.cern.ch (port 7653) ``` 3. Get further authentication and authorization info from the `XrdCl::DefaultEnv::GetPostMaster()->QueryTransport` not just the auth system. i.e. for GSI: CAdir, CRLdir, UsrProxy... [2] # Questions 1. Why do we see an auth system on the site redirector but not on the main storage node? (We have used the query [3] to print it) ``` Traceroute: cms-xrd-global.cern.ch, gfe02.grid.hep.ph.ic.ac.uk (gsi), sedsk84.grid.hep.ph.ic.ac.uk ``` Thank you in advance for your time!
