Hi Everyone, I have recently setup successfully a one network LVS-NAT for my company, where I am doing load balancing for servers related to mapquest routing and mapping services.
Whenever I connect to the director's VIP the connection is slow with a 5 second delay for each connection. But if I connect to the real server directly, the connection is pretty fast. I have seen the tcpdump as per the LVS HOWTO and mini-HOWTO, and they seem to look good. I have stopped the firewall "iptables" on both director and real servers. My setup is as follows: (I am using keepalived for monitoring real servers): VIP: 3.182.158.246 DIP: 3.182.158.197 RIP: 3.182.158.5 RIP: 3.182.158.247 CIP: 3.181.156.128 If you see in the following tcpdump, you see approximately 5 second delay between each successive request: 17:52:30.537328 IP 3.181.156.128.2585 > 3.182.158.246.9811: P 924411595:924411985(390) ack 2847019106 win 64512 17:52:30.538675 IP 3.181.156.128.2585 > 3.182.158.5.9811: P 924411595:924411985(390) ack 2847019106 win 64512 17:52:30.545346 IP 3.182.158.5.9811 > 3.181.156.128.2585: P 1:282(281) ack 390 win 6432 17:52:30.545375 IP 3.182.158.246.9811 > 3.181.156.128.2585: P 1:282(281) ack 390 win 6432 17:52:35.250777 IP 3.181.156.128.2586 > 3.182.158.246.9810: P 2797076163:2797076628(465) ack 2857607107 win 64512 17:52:35.250786 IP 3.181.156.128.2586 > 3.182.158.5.9810: P 2797076163:2797076628(465) ack 2857607107 win 64512 17:52:35.274238 IP 3.182.158.5.9810 > 3.181.156.128.2586: . 1:1371(1370) ack 465 win 6432 17:52:35.274252 IP 3.182.158.246.9810 > 3.181.156.128.2586: . 1:1371(1370) ack 465 win 6432 ............... ................. 17:52:40.323811 IP 3.181.156.128.2587 > 3.182.158.246.9810: P 1202139258:1202139723(465) ack 2869095928 win 64512 17:52:40.323834 IP 3.181.156.128.2587 > 3.182.158.5.9810: P 1202139258:1202139723(465) ack 2869095928 win 64512 17:52:40.340396 IP 3.182.158.5.9810 > 3.181.156.128.2587: . 1:1371(1370) ack 465 win 6432 17:52:40.340430 IP 3.182.158.246.9810 > 3.181.156.128.2587: . 1:1371(1370) ack 465 win 6432 -------------------- 17:52:45.232198 IP 3.181.156.128.2588 > 3.182.158.246.9810: P 1103285587:1103286052(465) ack 2872348289 win 64512 17:52:45.232211 IP 3.181.156.128.2588 > 3.182.158.5.9810: P 1103285587:1103286052(465) ack 2872348289 win 64512 17:52:45.243122 IP 3.182.158.5.9810 > 3.181.156.128.2588: . 1:1371(1370) ack 465 win 6432 17:52:45.243133 IP 3.182.158.246.9810 > 3.181.156.128.2588: . 1:1371(1370) ack 465 win 6432 17:52:45.243123 IP 3.182.158.5.9810 > 3.181.156.128.2588: P 1371:2049(678) ack 465 win 6432 Requesting any help in this regard.
