MyproxyProblem
Due to a problem with the firewall, we are sometimes unable to reacht the myproxy site of cern.
A hack is to add a static route to these servers.
Current situation (it goes through 193.190.247.65):
[root@m2 ~]# traceroute myproxy.cern.ch traceroute to myproxy.cern.ch (128.142.168.114), 30 hops max, 40 byte packets 1 rtr02.iihe.ac.be (193.190.247.65) 0.835 ms 1.076 ms 1.310 ms 2 172.16.156.254 (172.16.156.254) 0.812 ms 1.052 ms 1.287 ms 3 172.16.158.253 (172.16.158.253) 1.027 ms 1.025 ms 1.264 ms 4 fe.m20.access.brussels.belnet.net (193.191.4.93) 2.741 ms 2.736 ms 2.729 ms 5 10ge.cr2.brueve.belnet.net (193.191.16.22) 5.964 ms 5.961 ms 5.953 ms 6 belnet.rt1.ams.nl.geant.net (62.40.124.161) 7.186 ms 6.201 ms 5.965 ms 7 so-2-0-0.rt1.fra.de.geant2.net (62.40.112.9) 15.626 ms 15.604 ms 15.597 ms 8 so-5-0-0.rt1.gen.ch.geant2.net (62.40.112.162) 25.321 ms 25.315 ms 25.308 ms 9 switch-lb2-gw.rt1.gen.ch.geant.net (62.40.124.106) 25.286 ms 25.295 ms 25.288 ms 10 e513-e-rbrxl-1-te1.cern.ch (192.65.184.222) 25.275 ms 25.273 ms 25.266 ms
- Bypass through ccq.wn.iihe.ac.be (traffic is routed trough the GEANT gateway by default):
[root@m2 ~]# route add -host 128.142.168.114 gw 192.168.10.100 [root@m2 ~]# route add -host 128.142.168.104 gw 192.168.10.100
(two IPs for myproxy.cern.ch)
Then you see the traffic goes through ggw (our gateway to GEANT network)
