Hello again :-)
i have another question about the functional range of the net-snmp library. I found some other questions in the user-list which concern nearly the same problem, but i could not find a good solution for that. So what is it all about: What i like to do is to write a proxy. This proxy communicates with one manager and different agents. >From the view of the manager the proxy should simulate different agents. These agents are really existing. >From the view of the agents the proxy should simulate one manager. This manager is also existing. The manager can send packets to a specific agent using a specific ip address of one of my virtual interfaces: ifconfig eth0:1 192.168.1.2 netmask ... // agent 1 ifconfig eth0:2 192.168.1.3 ... // agent 2 ... To forward the packets, i need to change the source and destination ip addresses and ports. Now 3 problems: 1. When an agent sends a packet to the manager, "i have to know which agent sends the packet". I saw that the source ip address of a pdu is in the transport_data field of the pdu. Can i always find the source address of a packet in this field? Or is there another possibility to find out, who sent the packet? (When i know the agent who sent the packet i can send out the packet on the right virtual interface.) 2. How can i specify the interface where i want to send out the packet? 3. When the manager sends a packet, i have to know which agent should get the packet. So i need the destination ip address. I will know this, if i find out, which specific interface received the packet. But how can i do this? Summary: How can i get packets from one or more interface(s)? How can i get the source address of a received pdu?. How can i get the destination ip address of a received pdu (when i am listening on different interfaces)? How can i specify the interface to send out the pdu? Thanks a lot for any hint Susanne ______________________________________________________________ Verschicken Sie romantische, coole und witzige Bilder per SMS!
