From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0) Description of problem: ppp on demand on Readhat 7.1 (seawolf)The System hangs at startup while attempting to briging up ppp device. This is a clean FULL install. How reproducible: Always Steps to Reproduce: 1.edit /etc/sysconfig/network-scripts/ifcfg-ppp0 add yes to the demand line 2.Reboot system 3.Watch system not start and hang on ppp Actual Results: tough one here, the system as expected didnt start, so I had to push the big button on the front to cycle the power and watch it not start again and again and again. Expected Results: The system should have started Additional info: No output messages, as the system never made it far enough to generate any. Yet I could watch over and over the pretty little green OK prompts that would appear everytime before I had to hit the cycle power button.
Same symptoms for me. Ihave a ZyXEL Elite 2864ID and have been trying to configure it to be used for DoD. If I change "DEMAND=yes" to "no" in /etc/sysconfig/network-scripts/ifcfg-pppX, everything is fine, else I have A Zombie ifup-ppp and /etc/init.d/network start does'nt work. Aditionaly, if i ping an address outside of my subnet, the interface is dialing and everything works fine. Mayibe it is because pppd not dialing the line with the 'demand'- parm?
Check out the proposed fix for bug # 37392. I think this is the same problem.
In reference to bug id #37392, The bug appears to be the same listed, but the potential resolution does not work. I have tried all manners of the potential configurations regarding detach updetach nodetach and with no entry at all. Most yeild the same results, as the system hanging on the ppp device. Others give error codes that resolve to unknown options. This problem is still unresolved and even with the new kernel and all new patches applied, nothing has been fixed.
What follows is an amendment to the solution originally proposed in bug # 37392: In addition to my proposed solution above, you may also need to do the following: Locate the line in /etc/sysconfig/network-scripts/ifup-ppp that reads as: exec /sbin/ppp-watch "${DEVICE}" "$@" (this is line 17 on my installation) and insert a # symbol at the beginning of that line to comment it out. ppp-watch attempts to provide on-demand functionality for a ppp link. Unfortunately, in this script, it only results in a contentious redundancy with pppd's default behavior, which is to wait in the background anyway, like the good little daemon that it is. NEVER give up. LMK what results you all get. - gabriel
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.
