How to packet capture the whole traffic flow in VIP by Automap
Hi, I do have a VIP configured using Automap. 2 nodes on the pool member. Now, the problem is the log on the nodes member will always show the self IP as a source IP address. Configure X-forwarded will not work for my application due the the network setup. I try packet capture with command: tcpdump -ni 0.0:nnnp -s 0 host or port -w /var/tmp/test.pcap On Wireshark, if follow the TCP stream, it won't show the full traffic flow. It just either "self IP and node IP" or "actual source IP and VIP" How to capture/filter the packet so that I can have a full set of the traffic flow?
Packet based load balancing instead of connection based (default)
Hi everyone, I have a requirement to load balance iso 8583 echo messages across two servers in a pool. I used a performance Layer 4 virtual server to attempt achieving this because I reckon that is the type of virtual server that could fulfill the requirements of load balancing all the requests across the 2 servers in the pool. However, requests are only being sent to one pool member. I also tried to craft an iRule (see below) to do this, still requests are only sent to one pool member. when CLIENT_ACCEPTED { log local0. "ACCEPTED !!" TCP::collect } when CLIENT_DATA { log local0. "DATA !!" #to get the length of messagein hexadecimal,the length info can be get from the first 2 byte binary scan [TCP::payload] H4 len log local0. $len #convertlentodecimal scan $len %x len log local0. $len #totalmessage length is length + 2 set len [expr { $len + 2} ] if {[TCP::payload length] < $len} { TCP::collect [expr {$len - [TCP::payload length]}] return } TCP::release $len TCP::notify request TCP::collect } when LB_SELECTED { log local0. [LB::server] } when SERVER_CONNECTED { log local0. "Server Connected !!" TCP::collect } when SERVER_DATA { log local0. "response: [TCP::payload]" TCP::release TCP::notify response TCP::collect } Has anyone done packet-based load balancing before? Any ideas?
