Red Hat Bugzilla – Bug 67789
demand dial ppp hangs if set to autoboot
Last modified: 2014-11-25 10:30:45 EST
Description of Problem: If you configure a ppp interface to auto dial mode(for demand dial), and set it to start automatically on bootup, it will hang on starting ppp0 until network activity trigger the dial for the first time. This unfortunately will not happen in the bootup scripts since they wait for ppp0 to come up before proceeding to anything else. How Reproducible: Very Repeatable Steps to Reproduce: 1. Create a dialup connection with auto dialing(instead of manual), and setup to start on bootup. Leave rest of options default 2. reboot(or run /etc/init.d/network start). It will sit on starting ppp0 until network activity triggers the first dial 3. Actual Results: Hangs on starting ppp0 Expected Results: For a demand dial configuration, it should continue past the ppp0 w/out waiting for the modem to dial Additional Information: We solved this temporarily by changing the ONBOOT='yes' to no, and putting an "ifup ppp0 &" in the rc.local. I remember seeing a setting to avoid this, but I cannot find this anymore.
ppp-watch is supposed to continue if given a third parameter "boot" as the (buggy) man pages states. It is NOT honoured.
Please verify this with a newer version of Red Hat Enterprise Linux or Fedora Core and reopen it against the new version if it still occurs. Closing as "not a bug" for now.
