Hi All, I try to login at a modem connected to an embedded linux system, but I don't get it to work. I tried almost everything. I hope someone knows what is going wrong. The system I use is the developerboard lx with an ETRAX 100 LX chip from Axis. I installed ppp and mgetty on the devboard. Mgetty is a getty specially for modems. I also tried with the getty from tinylogin and with agetty, but those gave the same problems. After the modems have connected I can see in the ppp logfile (of the client):
send [LCP ConfReq id=0x1> <pcomp> <accomp>] last message repeated 9 times LCP: timeout sending Conf Connection terminated And then the connection ends. In the other ppp logfile I get the messageges: pppd 2.4.1 started by root, uid 0 Couldn't restrict write permissions to /dev/ttyS0: Read-only file system I tried to set up a ppp connection in the other way (devboard as client, normal pc as server) and this worked without any problems. There was a little difference in the 2 ppp logfiles from the server: The logfile from the working ppp connection (devboard as client): ..... waiting for line to clear (VTIME), read: looking for utmp entry... (my PID: 23951) utmp + wtmp entry made tio_set_flow_control ( HARD ) getlogname (AUTOPPP), read:~[ff]}#[c0]! input finished with '\r', setting ICRNL ONLCR tio_get_rs232_lines: status: RTS CTS DSR DTR DCD ..... The logfile from the not working ppp connection (devboard as server): ..... waiting for line to clear (VTIME), read: looking for utmp entry... (my PID: 52) tio_set_flow_control ( HARD ) getlogname (AUTOPPP), read:~[ff]}#[c0]! input finished with '\r', setting ICRNL ONLCR tio_get_rs232_lines: status: RTS CTS DSR DTR DCD RI ..... A difference is that at the last one there is no utmp and wtmp entry made. I checked on the devboard, and there is a utmp file, but no wtmp file. There is also a difference in the status of the 232_lines, so I tested the serial line with a test program installed on the devboard: 'hwtestserial -d /dev/ttyS0 -loopback 4' and I got the message: 'test failed: CD and RI high when expected to be low (RTS high, DTR low)' this is not good, is it? I also tried to dialin at the devboard without ppp, but then when typing a username after the loginprompt nothing happens. Does anyone know what might be going wrong and what to do about it?
