Thanks for reply. There is no firewall in that network. This is just separate network. and I can say they are directly connected to each other using L1 switch and no other connection to outside world. It was jut testing that I have giving public IP to one of interface in one host. - The association look like with public IP. sh-3.2# cat /proc/net/sctp/assocs ASSOC SOCK STY SST ST HBKT ASSOC-ID TX_QUEUE RX_QUEUE UID INODE LPORT RPORT LADDRS <-> RADDRS HBINT INS OUTS MAXRT T1X T2X RTXC ffff8800089b0000 ffff8800335944c0 2 1 3 37916 3 516 0 0 10635 48520 7168 127.3.253.1 127.3.21.1 127.4.253.1 127.2.253.1 127.1.221.1 164.48.1.1 127.3.254.1 <-> *127.4.252.1 7500 300 300 10 0 0 0 ffff8800089b2000 ffff880033594000 2 1 3 50717 4 516 0 0 10634 60890 7169 127.3.253.1 127.3.21.1 127.4.253.1 127.2.253.1 127.1.221.1 164.48.1.1 127.3.254.1 <-> *127.4.252.1 7500 300 300 10 0 0 0 ----------------------------------------------------------------------------- - But if I give private IP (10.1.1.1) this look like. sh-3.2# cat /proc/net/sctp/assocs ASSOC SOCK STY SST ST HBKT ASSOC-ID TX_QUEUE RX_QUEUE UID INODE LPORT RPORT LADDRS <-> RADDRS HBINT INS OUTS MAXRT T1X T2X RTXC ffff88003c721800 ffff8800335944c0 2 1 3 22045 2 0 0 0 5674 47434 7169 127.3.253.1 127.3.21.1 127.4.253.1 127.2.253.1 127.1.221.1 <-> *127.4.252.1 7500 300 300 10 0 0 0 ffff88003c720800 ffff880033594000 2 1 3 36124 1 0 0 0 5673 58513 7168 127.3.253.1 127.3.21.1 127.4.253.1 127.2.253.1 127.1.221.1 <-> *127.4.252.1 7500 300 300 10 0 0 0 - I may be wrong but is it possible that when we do bind with on IP (and if multi homing is enabled) it'll build with all available interfaces? Please forgive if I ask stupid question. First time I am doing network programing and trying to learn this.
