Thanks. It *really* sucks that they are assigned randomly sometimes, since this could cause huge problems, e.g., on the virtualbox build farm I run I have ubuntu setup to assign a static ip address to eth1. If ever eth0 and eth1 were swapped, then the network would just break. Fortunately, I have never seen this randomness behavior myself. In any case, right now virtualbox always assigns 192.168 to the host-only address, and 10.0 for the non-host-only address. In fact, it's always 10.0.2.15 for the NAT address for *every* virtual machine, i.e., even the 15 doesn't change! So instead of looking for the address of eth1, I can change the script to look for the address that isn't 10.0.*. -- William > eth0 Link encap:Ethernet HWaddr 08:00:27:E9:A7:2C > inet addr:10.0.2.15 Bcast:10.0.2.255 Mask:255.255.255.0 > UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 > RX packets:6 errors:0 dropped:0 overruns:0 frame:0 > TX packets:13 errors:0 dropped:0 overruns:0 carrier:0 > collisions:0 txqueuelen:1000 > RX bytes:1524 (1.4 KiB) TX bytes:1494 (1.4 KiB) > Interrupt:11 Base address:0xd020 > > eth1 Link encap:Ethernet HWaddr 08:00:27:EE:E5:47 > inet addr:192.168.56.101 Bcast:192.168.56.255 > Mask:255.255.255.0 > UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 > RX packets:216 errors:0 dropped:0 overruns:0 frame:0 > TX packets:295 errors:0 dropped:0 overruns:0 carrier:0 > collisions:0 txqueuelen:1000 > RX bytes:33384 (32.6 KiB) TX bytes:357196 (348.8 KiB) > > lo Link encap:Local Loopback > inet addr:127.0.0.1 Mask:255.0.0.0 > UP LOOPBACK RUNNING MTU:16436 Metric:1 > RX packets:2 errors:0 dropped:0 overruns:0 frame:0 > TX packets:2 errors:0 dropped:0 overruns:0 carrier:0 > collisions:0 txqueuelen:0 > RX bytes:100 (100.0 B) TX bytes:100 (100.0 B) > > /root/sage_notebook.sagenb/home/admin/0/cells/2 > > -Marshall > -- William Stein Associate Professor of Mathematics University of Washington http://wstein.org --~--~---------~--~----~------------~-------~--~----~ To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
