I could use a "third eye" on fine tuning the 56k baud packet interface to Linux. Here's where I am at: The 56k port is via a PackeTwin interface (serial sync rs-422) that is connected to the linux kernel as dmascc0. This interface is then sent into two directions, The first to Tnos using the Net2Kiss feature and also to ax25-utils inwhich a port in xfbb (7.01f) is linked. Some tests are as follows: Telnet from the linux console, using the destination IP Addr, gets a response from the destination site but nothing shows up on the screen. Telnet from the Tnos console and I get an immediate connect and destination prompt. Connection from a distant source to the ax25-util node, I get a good connection and handshake. This also includes a successful connection to the LinFBB bbs (7.01f) via the linux node. Connection directly to the xfbb callsign works but I get constant transmit/recieve frames going back and forth too/from source-destination (kinda like a highspeed pactor). Using the CALL application from the linux console works great to the destination. Current linux interface mtu is 576 along with the Tnos mtu. ax25-util mtu is 256 as-well-as the LinFBB settings. I was just wondering why it works great from the Tnos and Call applications but not from the Linux console or LinFBB application? Last question is regarding the Linux Node. I have the node set up with a netrom and netnod ports with the netrom being the dummy switch port (callsign-10:#alias) and the netnod (callsign-3:alias). I have configured netrom neighbors using the nrparms commands as well. Along with this I pointed the linux node across an axip link to another Tnos machine also running netrom with handset parms. After a bit of time these nrparm routes die off which leads me to thing that the linux node does not hear any broadcasts. I do have the permissions set to '1' within the nrbroadcast: 145 5 192 140 1 439 5 222 140 1 dmascc0 5 222 140 1 dmascc1 5 222 140 0 nrports: netrom KC6IKE-10 #SAW 235 Switch Port netnod KC6IKE-3 SAW 235 Real Node rc.local nrparms lines: # NRPARMS /usr/sbin/nrparms -node AA6QN-3 + SEE 222 6 axip AA6QN-3 /usr/sbin/nrparms -node WB6DGR + ARESBB 222 6 axip AA6QN-3 /usr/sbin/nrparms -node WB6WLV-10 + OTAY 222 6 dmascc0 WB6WLV-10 I am using node-0.3.0 Thank you in advance, John
