I'm experimenting with blockchains at home and in my debug logs are lots of errors showing that my nodes are trying to get addresses from the hard coded seed nodes, I know I can use connect to turn off this behaviour but I don't want to have to include that in my bitcoin.conf file.
I am using Bitcoin v0.10.
Any hints greatly appreciated :)

There are a few ways to do it, I personally went into src/net.cpp and commented out the if condition that triggers the lookup starting at line 1266.
// if (addrman.size() == 0 && (GetTime() - nStart > 60)) {
// static bool done = false;
// if (!done) {
// LogPrintf("Adding fixed seed nodes as DNS doesn't seem to be available.\n");
// addrman.Add(Params().FixedSeeds(), CNetAddr("127.0.0.1"));
// done = true;
// }
// }
Another effective fix was to remove all the encoded seed nodes from the two arrays located in src/chainparamsseeds.cpp

There is a seed vector (for TestNet or Regtest) of hard-coded seeds that gets populated in the source code (vFixedSeeds in src/chainparams.cpp i guess?). U can either comment out them or simply clear the vector to empty it. Then u can explicitly have your topology

the seed nodes are generated in contrib/seeds
curl -s http://bitcoin.sipa.be/seeds.txt > seeds_main.txt python makeseeds.py < seeds_main.txt > nodes_main.txt python generate-seeds.py . > ../../src/chainparamsseeds.h
just edit seed.main.txt
If u wanna turn off the hard-coded seeds (or DNS) AND also not give explicitly the topology you wish to connect, how will u even do any p2p communication? U will need to connect to peers in some way right – visweshn92 – 2016-04-07T06:00:21.870
I intend to add them manually in the config file with
addnodebut I keep getting annoying connection errors in my debug log. I just want to turn off the feature that tries to connect to the hard coded seeds. – derrend – 2016-04-07T06:14:50.957There is a seed vector (for TestNet or Regtest) of hard-coded seeds that gets populated in the source code (vFixedSeeds in src/chainparams.cpp i guess?).

I appreciate the help, i have already done that though - https://github.com/derrend/bitcointemplate/blob/master/src/chainparams.cpp Im looking at
– derrend – 2016-04-07T06:58:50.343src/chainparamsseed.handshare/seeds/, I think these may be what I am looking for.Please paste the error. I can help u – visweshn92 – 2016-04-07T07:09:30.963
Thank you viesweshn92 but the mods i made to
src/chainparamsseedshave fixed my problem, I will supply a more detailed answer below later. Thanks again :) – derrend – 2016-04-07T07:19:32.293Awesome then! Kindly upvote my answer/comment ;) – visweshn92 – 2016-04-07T09:24:33.847
