[HTCondor-users] Capital Letters in DNS names

Hi Everyone,

We have a gatekeeper for the US ATLAS site MWT2 that frequently returns its name as iut2-gk.mwt2.ORG rather than the usual iut2-gk.mwt2.org. I find the .ORG form of the address in the startd_history files in all ~250 compute servers at the IU site. If I look at the ClassAds the startd_history file I find both forms:

GlobalJobId = "iut2-gk.mwt2.ORG#717933.0#1649642845"
MyAddress = "<[2001-18e8-c02-5-216-3eff-fe72-640e]-9618&alias=iut2-gk.mwt2.ORG&noUDP&sock=shadow_1617_129b_619321>"


Environment = "APFCID=13262849.30 APFMON=http://apfmon.lancs.ac.uk/api ATLAS_LOCAL_AREA=/osg/mwt2/app/atlas_app/local OSG_HOSTNAME=iut2-gk.mwt2.org OSG_APP=/osg/mwt2/app HARVE
GridResource = "condor iut2-gk.mwt2.org iut2-condor.mwt2.org:9618"

However it is the .ORG form that may be causing trouble when Panda uses it to form the its own internal batchID using a complicated regex expression. Somehow Panda gets "EPoll: uct2-gk.mwt2.org#92361.0#1650636427" rather than "uct2-gk.mwt2.org#92361.0#1650636427" for itsÂinternal batchID.

Brian Lin (cc'd) helped me in the OSG SW Slack channel and confirmed that:

1) it looks like it's in the schedd name itself
$ podman run --rm -it opensciencegrid/hosted-ce:3.6-release condor_ce_status -pool iut2-gk.mwt2.org:9619 -schedd -af name


2) it doesn't appear that it's coming from config, though

I have grepped extensively in /etc and /var without finding the string ORG in any configuration file though it does of course appear lots in log files and occasionally in files not related to condor.

Thanks for any help!
