Hi, We have setup xrootd (v5.4.0) and checked that file transfer works. but log file says "tpc is not supported", even though I believe I have the configuration file for TPC. The xrdcert and xrdkey pair is self-signed. Also, log file has these two lines: Config warning: 'xrootd.seclib' not specified; strong authentication disabled! Config asynchronous I/O has been disabled! How to get these three: tpc, seclib, and async i/o enabled? ## The config file xrootd.export /poolz_00/dune oss.cache public /poolz_00/cache_00 xa all.adminpath /var/spool/xrootd all.pidpath /var/run/xrootd continue /etc/xrootd/config.d/ all.adminpath /tmp/xrootd/var/spool all.pidpath /tmp/xrootd/var/run oss.localroot /tmp all.export /xrootd xrootd.chksum adler32 xrd.tls /etc/grid-security/xrd/xrdcert.pem /etc/grid-security/xrd/xrdkey.pem xrd.tlsca certdir /etc/grid-security/certificates refresh 8h xrootd.tls capable all -data xrootd.seclib /usr/lib64/libXrdSec.so sec.protparm gsi -vomsfun:libXrdVoms.so -vomsfunparms:dbg sec.protocol gsi -ca:1 -crl:3 -gridmap:/dev/null acc.audit deny acc.authdb /etc/xrootd/auth_file acc.authrefresh 60 ofs.authorize 1 ofs.tpc logok autorm pgm /etc/xrootd/xrdcp-tpc.sh setenv X509_USER_CERT = /etc/grid-security/xrd/xrdcert.pem setenv X509_USER_KEY = /etc/grid-security/xrd/xrdkey.pem Thanks, Nagaraj ######################################################################## 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
