Description of problem: pppd does not exist when the modem is hung or powered down. Version-Release number of selected component (if applicable): ppp-2.4.4-1.fc6 How reproducible: Every time Steps to Reproduce: 1. Simulate a hung modem by powering down the modem or pointing pppd to a serial port that is not connected to any device. 2. Create a test dial-up connection (phone number, login, password are irrelevant. 3. Run <ifup test_connection_name> Actual results: In /var/log/messages: wvdial correctly reports "Modem not responding". pppd correctly reports "Connect script failed". But pppd does not exit An strace reveals that it hangs with ioctl(8, SNDCTL_TMR_CONTINUE or TCSETSF, {B9600 opost isig icanon -echo ...}) = 9 Trying to change the port settings with stty also hangs, so I suspect that the serial port is in blocking mode waiting for a read or write request to finish. And since the modem is hung, pppd will pretty much hang forever. Expected results: pppd should exit after reporting "Connect script failed" Additional info: This is for an automated off-site system, so the dial-up script needs to be robust. A workaround is to run ifup <name> in the background. You can then check the PID at regular intervals. The process will complete if the dialup was successful, otherwise a killall -9 pppd wil sort it out. But this shouldn't be necessary.
