Iain et al; Like with xNOS, the TCP MSS needs to be set per interface, also Ugo doesn't specify which mode he's using (VC vs. DG) The "out of sequence" frames may be caused by using datagram mode instead of virtual circuit mode. IP over RF works best in a virtual circuit mode which is what NetRom uses as well. Datagram mode often can (and will) drop frames thus making them appear "out of order".
With a properly set interface, the ip window will auto-adjust within the maximum limit specified within the parameters of the interface. While finding the setting is a bit obscure IMHO, it can be done. >From the URONode at tapr.org mail list: iptables -t mangle -A POSTROUTING -o <interface> -p tcp --tcp-flags SYN,RST SYN -j TCPMSS --set-mss 216 Since your send is outbound only, this is fine. Your interfaces for the above would be for a standard ax25 only interface (ie: ax0/ax1/etc). For a NetRom interface (ie: nr0/nr1/etc) subtract another 20 from the ending 216 to make room for the protocol headers of NetRom. Repeat the above for UDP if required. Iain, I can have a discussion with you offlist re: LinBPQ if you wish and save you some time. -- The most difficult egg to beat is one that is hard boiled. 73 de Brian Rogers - N1URO email: (see above) Web: http://www.n1uro.net/ Ampr1: http://n1uro.ampr.org/ Ampr2: http://nos.n1uro.ampr.org Linux Amateur Radio Services axMail-Fax & URONode http://uronode.sourceforge.net http://axmail.sourceforge.net AmprNet coordinator for: Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, Pennsylvania, Rhode Island, and Vermont. -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
