[21:22] waited for 10 minutes before rolling back [21:23] are both on the same vlan? treat them both as if they are physical machines [21:24] i have a /29 and currently assign 3 ip's to my dedicated and 2 to my vps. when trying to switch the most "active" ip, it just doesn't seem to work [21:25] i tried a similar switch with an unused ip some days ago which worked [21:33] is there something i fundamentally fail to understand here? :/ [21:34] sounds like you've done your homework, if the vps stops responding to it and the other system starts, arp cache timeouts should be all that is in your way [21:34] its possible you hit a lucky time in the arp cache timeout in your testing, no guarantees though [21:34] the old system doesn't respond to old ip (and ifconfig doesn't show it), new machine allocates it (shows up in ifconfig), but i cannot have 10 minutes more fo downtime not knowing :( [21:35] update dns to point to another ip responded to by the new system? [21:36] i don't control all domain names pointing to that ip [21:36] <_mnathani_> jbergstroem: Is the IP being assigned to a NIC that already has an IP and therefore assigning multiple IPs to the sam MAC address or is this a new MAC ? [21:36] _mnathani_: i bond the two interfaces to one mac address that has multiple ip addresses assigned to it [21:37] i use the ip that is moved as primary (all outgoing is going through it) [21:37] <_mnathani_> can you try making the IP you are moving the primary IP on the dedicated and ping the gateway [21:37] <_mnathani_> that would update the ARP I am pretty sure [21:38] i did [21:38] gateway didn't respond [21:38] <_mnathani_> thats odd [21:38] yes, i agree [21:38] <_mnathani_> could you ping an outside internet ip? [21:38] <_mnathani_> like say 8.8.8.8 [21:39] no, nothing from the machine since outgoing traffic was meant to go through that ip [21:39] things i bind to the other ip's work fine though [21:40] <_mnathani_> Did your VPS get upgraded to use gigabit networking? [21:40] no [21:40] 'beta' and was moving any time anyway [21:40] <_mnathani_> and the gateway assigned is the same on both the VPS and dedicated? [21:40] yes, same netmasks, broadcasts etc [21:42] <_mnathani_> when you move the IP from the VPS, do you assign another IP / Primary to the VPS ? [21:42] yes, i have two assigned so i don't have to mess with kvm. [21:42] the second ip i used to experiment this transition with a coulpe of days ago. worked well. [21:43] <_mnathani_> can you ping the troublesome ip from the vps after the move to dedicated? [21:43] no. not from anywhere [21:44] <_mnathani_> my understanding of ARP networks infrastructure is that they place VPS and Dedicated on the same VLAN, so in thery it should work just fine [21:44] yes, that's what help says as well, and from moving other ip's im inclined to agree [21:44] <_mnathani_> are you able to flush arp cache and retry? [21:44] how? [21:45] <_mnathani_> what OS? [21:45] linux [21:45] but is it really my arp cache that needs to be flushed? [21:46] <_mnathani_> it might be whats causing the gateway to retain the VPS MAC address for the troubled IP [21:46] <_mnathani_> http://www.lainoox.com/display-add-flush-arpcache-linux-arp/ [21:47] <_mnathani_> instead of flush, you could delete the specific entry [21:47] arp cache displays same records [21:47] <_mnathani_> like: [21:47] <_mnathani_> arp -i eth0 -d 10.11.12.13 [21:47] <_mnathani_> on dedicated or virtual? [21:47] yeah, i know how to clear it, but are not very willing to get additional downtime to try it [21:47] on both [21:48] <_mnathani_> after removing from vps it should no longer show the old mac, it should update to the new mac from dedicated [21:48] but shouldn't the cached gateway mac be the same on both machines? [21:48] <_mnathani_> yes, gateway mac should be the same [21:49] i don't think arp caches locally assigned ip addresses. [21:50] <_mnathani_> right [21:50] <_mnathani_> I was going for the troubled IP after assigning to dedicated, then ping from vps and check cache [21:51] just tried, and nope. [21:51] no cache. [21:52] <_mnathani_> when pinging the ip from outside the network, does it timeout when moving to dedicated? [21:53] <_mnathani_> or does the old vpn still respond? [21:53] <_mnathani_> *vps [21:53] i can't reach the gateway at all if i migrate the ip address [21:53] times out [21:53] old vpn does not have that ipa ddress assigned, so it doesn't respond [21:55] there. just switched [21:55] <_mnathani_> seems like some kind of security on the switch port [21:57] <_mnathani_> one other thing, your dedicated server has 2 network interfaces, are you doing any kind of redundant load balancing configuration? [21:57] took 3 minutes though [21:57] <_mnathani_> so its working now? [21:58] yes [21:58] so, nothing from my end [22:54] *** jbergstroem has quit IRC (Remote host closed the connection) [22:54] *** easymac has quit IRC (Write error: Broken pipe) [22:55] *** easymac has joined #arpnetworks [22:55] *** easymac has quit IRC (Changing host) [22:55] *** easymac has joined #arpnetworks [23:00] *** jbergstroem has joined #arpnetworks
