I am having some troubles with iijppp and 2.1.0 [while it used to work fine with a July snap of 2.0.5]. First, a question: Is anyone running iijppp between two 2.1.0-RELEASE systems ? --- This does not work for me. I am trying to sort out the details, as there are many things involved (modem type, modem settings, OS release, mgetty configuration etc.). Still I believe I can say that the problem seems to be with 2.1.0 and not with the rest of the system I will use the following DEFINITIONS PPP server: a system which is running mgetty on a serial port, where users can log into and, from the shell prompt, run "ppp - direct" PPP client: a system where a user invokes "ppp", then manually dials into a PPP server, logs in, and invokes "ppp - direct" on the server SYMPTOMS: * A 2.1.0-RELEASE PPP-server is unable to setup a ppp connection with a PPP-client (running 2.1.0-RELEASE as well). The same PPP-client works fine with a 2.0.5-9507XX-SNAP PPP-server. DETAILS: I have a total of 4 systems, as follows: ID OS Modem studenti 2.0.5-9507XX-SNAP cirrus-logic cisid 2.1.0-RELEASE rockwell labinfo2 2.1.0-RELEASE rockwell prova 2.1.0-RELEASE cirrus-logic All run mgetty-0.22, hopefully configured appropriately. "studenti" and "cisid" have a receive-only line, so I cannot use them as PPP-clients. The others have bidirectional lines. There is no special setting in the /etc/ppp/* files (basically, they are as shipped with the releases). I just set, on the PPP-client, the addresses with "set ifaddr 200.0.0.1 200.0.0.2" and dial manually giving at commands. Have done the following cross-tests: PPP-client labinfo2 prova PPP-server studenti WORKS WORKS cisid NO NO labinfo2 -- NO prova NO -- "WORKS" means that everything works fine, the link goes up, and I can use the IP connection. "NO" means that I can login, run ppp -direct, then the PPP-client returns to command mode and says something like "starting packet mode". >From here on, if I ping the remote side, I don't get any answer. Looking with netstat at the two systems, I see that the client sends the packet, the server receives them, replies, but the client does not get the reply. As it can be seen, "studenti" works fine (runs 2.0.5). The modem on "labinfo2" and "prova" should be configured correctly (otherwise they would not work in client mode). Any suggestion ?
