I believe network availability is a non deterministic factor in the startup procedures of most network software. I found this in LEAF routers built with PCMCIA cards, dead peer detection scripts for ipsec, e.t.c. I believe some of the init routines are not as network friendly as they might, or should, be. Some should indeed wait for network connectivity to be up before attempting to use the network. Shorewall is an example of this behaviour. Most of the time it works fine, but sometimes, especially with pppoe or radio connections, it is started before all network connections are fully operational. This should be either adressed generically in the init sequence or each such init script should check for network connectivity to be complete before attempting to use those ressources.
One possible solution could be to check in the ifup/ifdown routines for the various network interfaces or somehow to check at the exit of networking init. I added such checks to most of my installations. It appears to be a phenomenon which appears pretty inconsistently on a wide range of hard and software. I found problems of this sort are pretty difficult to diagnose as often the diagnostic code introduces sufficient delay for the problem to go away. It would be nice if we could find a generic solution to this phenomenon. cheers Erich ------------------------------------------------------------------------- Take Surveys. Earn Cash.
