Hello, *! I've tried to solve this on see-sa1-tech level, but no redemption came out yet. I am trying to run misc. test from our local UI machine. As long as I perform local to our site globus-* operations - like job submission etc. - they succeed. When I am trying to do this via the RB ( which is rb.isabella.grnet.gr) I get this very strange indication from UI: ======== START SESSION DUMP ===== [ds-con] /gridhome/maxim > globus-url-copy -dbg file:///etc/hosts gsiftp://rb.isabella.grnet.gr/tmp/foo.tmp$$ debug: starting to put gsiftp://rb.isabella.grnet.gr/tmp/foo.tmp16305 debug: connecting to gsiftp://rb.isabella.grnet.gr/tmp/foo.tmp16305 debug: response from gsiftp://rb.isabella.grnet.gr/tmp/foo.tmp16305: 220 rb.isabella.grnet.gr GridFTP Server 1.12 GSSAPI type Globus/GSI wu-2.6.2 (gcc32dbg, 1109600000-42) ready. debug: authenticating with gsiftp://rb.isabella.grnet.gr/tmp/foo.tmp16305 debug: error reading response from gsiftp://rb.isabella.grnet.gr/tmp/foo.tmp16305: a system call failed (Connection reset by peer) debug: fault on connection to gsiftp://rb.isabella.grnet.gr/tmp/foo.tmp16305: a system call failed (Connection reset by peer) debug: data callback, error a system call failed (Connection reset by peer), buffer 0xb70dc008, length 0, offset=0, eof=true debug: operation complete ======== END SESSION DUMP ===== RB administrator has shown me these from the RB machine: Dec 2 23:08:34 rb gridftpd[7608]: lost connection to ds-con.cs.technion.ac.il [132.68.37.242] Dec 2 23:10:05 rb gridftpd[7771]: lost connection to ds-con.cs.technion.ac.il [132.68.37.242] I've talked to our firewall managers, and according to them, there is no 'reset connection' (REJECT) policy in the firewall on anything except SMTP. Has anybody experienced this behaviour and found why it occurs ? Best regards, Max. There is hopeful symbolism in the fact that flags do not wave in a vacuum. -- Arthur C. Clarke
