bfgminer as a daemon : fails to contact pool during boot
Hi,
I'm trying to modify Debian's bfgminer package to make it run as a daemon. I wrote a patch including amongst other things, an init script that relies on Debian's start-stop-daemon utility to fork. It works flawlessly when manually run after boot, but not during boot. It's extremely weird.
BFGMiner exits after saying that it can't contact the pool:
[2016-05-16 18:35:13] Probing for an alive pool
[2016-05-16 18:35:14] No servers were found that could be used to get work from.
[2016-05-16 18:35:14] Please check the details from the list below of the servers you have input
[2016-05-16 18:35:14] Most likely you have input the wrong URL, forgotten to add a port, or have not set up workers
[2016-05-16 18:35:14] Pool: 0 URL: stratum+tcp://stratum.mining.eligius.st:3334 <credentials>
The debug output doesn't say anything more on this matter (it only adds information about hardware detection).
It's obviously not a misconfiguration problem with the pool URL/credentials since it works when run after boot. I'm pretty sure it's not a network access problem either, because during my numerous tests I tried to telnet the port on the pool host from withing the init script, and it worked. A lagging/slow pool without a backup could be a culprit too, but if BFGMiner wasn't happy with such a pool, the init script shouldn't work after boot either, right ? However, it does. I'm at a loss here.
So my question is: what could make BFGMiner fail in this case ?

Maybe name resolution/DNS isn't ready yet?
(thanks for answering so quickly)
A DNS failure is unlikely, since that would have made the telnet test fail, too.
Any other idea ?

Not sure, sorry. If you run it in strace, does it reveal anything interesting?

Sorry to bother you with this... I managed to trace the binary (including forks) through the init script, but since I'm an admin, I speak bash and POSIX shell fluently, but unfortunately not C, and thus I don't understand the resulting file at all... I tried to read it, but I didn't find anything relevant between the "Probing..." and "No servers..." write to STDOUT/STDERR calls.
May I please show it to you ?

Does it contain any sensitive information ? I didn't find my address in it, but I'm not sure there's nothing I missed.

Hi I setup the bfgminer bit 32 version for my Windows 10 desktop with Nivida graphic card. I also setup an Antpool account with a wallet. But when I startup the bfgminer against the antpool url: stratum+tcp://stratum.antpool.com:3333, then userid.worker and password (my antpool account information), I immediately got this error: Pool setup failed. Where do I get more error details? I checked my bfgminer folder and couldn't find any log or error file. Please help.
I also have my Norton security running. Could it be Norton is blocking my connection to the Antpool server?
