Josephine, You seem to have no chance with the ROHC library. Anyway, thank you for testing it !

Is the repetition a valid response or an error? It isn't a response nor an error, it is a simple debug message. It means that the tunnel regularly flushes the ROHC feedback data towards the tunnel peer. If it does not, the feedbacks would then be transmitted only when data is sent through the tunnel. In the case of an unidirectional VoIP stream going from peer A to peer B, feedbacks from peer B to peer A would be indefinitely blocked. > After setting up the interfaces and assigning ipv4 and ipv6 addresses > on both machines, the ping command generated this error: > > :~/rohc-1.2.0$ ping 10.0.0.1 > PING 10.0.0.1 (10.0.0.1) 56(84) bytes of data. > ping: sendmsg: No buffer space available > ping: sendmsg: No buffer space available > ping: sendmsg: No buffer space available > ping: sendmsg: No buffer space available > ............... > > Does anyone have a solution to this? Are there some interesting messages in the output of the rohctunnel commands when you encounter the problem ? If not, you probably got a problem of communication between the 2 tunnel endpoints. What is the output of the following commands on the 2 machines on which you run the rohctunnel commands ? # ip -4 addr # ip -4 route # iptables -L -vn # ping <IPv4 address of the other endpoint> Didier Barvaux Viveris Technologies _______________________________________________ Mailing list: https://launchpad.net/~rohc Post to : [email protected] Unsubscribe : https://launchpad.net/~rohc More help : https://help.launchpad.net/ListHelp
