IPv6 reverse lookup
Still waiting for network admin to setup IPv6 reverse lookup DNS.
W/o that, the dCache head node cannot start.
So I temporarily turned off v6 on the head node.
Tracepath after jumping to Internet2
Each block contains the v4/v6 tracepath in both directions.
(Some v6 traces for 128 were missing because I cannt access those WNs now.)
All v4 outgoing path are now thru chi. In-gping path still from asgc.
And all v4/v6 outgoing trace show too many hops.
But I see no problem yet.
Three network segments in NCHC:
- TC: 140.110.132.0/28 2001:e10:2000:132::/64
- TN: 140.110.122.96/28 2001:e10:4000:122::/64
- HC: 140.110.211.0/28 2001:e10:2000:211::/64
to/from CERN 128.142.x.x (some WNs)

CMS Federation
Currently, dCache xrootd door can handle direct access as well as the LFN-PFN mapping via CMS-TFC with storage.xml. For example, this request works,
# gfal-ls root://se01.grid.nchc.org.tw//store/test/xrootd/T2_TW_NCHC/store/user/chunyu/x
But CMS federation access doesn't,
# gfal-ls root://cms-xrd-global.cern.ch//store/test/xrootd/T2_TW_NCHC/store/user/chunyu/x
--> NOT WORKS!
According to https://twiki.cern.ch/twiki/bin/view/CMSPublic/DCacheXRootD, a stand-along (SLAC) xrootd server has to be installed as a federation host, running
cmsd: subscribing to a regional redirector viaall.manager any xrootd-cms.infn.it+:1213.xrootd: access the PNFS (dCache meta data mounted via nfs4) with the right authentification.
My cmsd is active. But I have trouble setting up the xrootd with LCMAPS correctly.
Asymm route
We changed IP for TC's grid on May 2023. But the transfers from TC to 128.x still fails.
