I've started this thread because connection to the server is unstable and I see such reports from other servers: +arp: 10.11.1.203 moved from 00:15:17:1a:6e:6f to 00:15:17:1a:6e:6d on em1 +arp: 10.11.1.203 moved from 00:15:17:1a:6e:6d to 00:15:17:1a:6e:6f on em1 +arp: 10.11.1.203 moved from 00:15:17:1a:6e:6f to 00:15:17:1a:6e:6d on em1 +arp: 10.11.1.203 moved from 00:15:17:1a:6e:6d to 00:15:17:1a:6e:6f on em1 +arp: 10.11.1.203 moved from 00:15:17:1a:6e:6f to 00:15:17:1a:6e:6d on em1 BIOS tells that NIC1 has 00:15:17:1a:6e:6c MAC and NIC2 has 00:15:17:1a:6e:6d. It's strange that 00:15:17:1a:6e:6d MAC is common for both NICs. > Bye, > Daniel -- Sergey
