Bitcoin server - set minimum transaction fee

[supermoney]

Hello fellows!
I'm actually running bitcoind server to receive and send transaction through my own software.
Transaction size of my spends are always near to 100kb/500kb, so how do I set a minimum/pseudo-fixed transaction fee in my bitcoin.conf/software? If you haven't figured out yet what I mean, I would always pay 0.0001 BTC for each spend cause they never exceed 1.000kb.
Hoping in a fast reply  

(SELF MADE) MOMENTANEOUS WORKAROUND:

Unfortunately, none of these works. How's that possible? What I'm doing wrong?

Are you testing any of these on the Mainnet?

No because I do not have enough bitcoins. However, I've seen many sending with "pseudo-fixed" fees on testnet too.

It's my understanding that testnet does not require any fees. This may be lending to your problem.

Also surely you have enough Bitcoin to test some 0.0001 sending fees. Just send them somewhere and bring them back (such as to Coinbase, etc).

Testnet requires fees too!
Then how do miners mine those bitcoins?  
Whatever, I've finally found the parameter: minrelaytxfee = <amount>

You can't, the reference implementation wallet always pays some-amount-per-1000-bytes-of-the-transaction.

The rules for the 0.10 release are:

+ By default, you always pay a fee (this is different from previous releases that would send transactions without a fee if they had high enough priority)  (run with -sendfreetransactions=1 to get the old behavior of sending high-priority transactions without a fee)
+ By default, the fee-per-kilobyte is estimated based on recent transaction confirmation history.

To get close to what you want (pay a fixed fee per transaction), run with -paytxfee=0.whatever  : that tells the wallet code to pay 0.whatever BTC per 1000 bytes. Most transactions are about 500 bytes big.

See here:  http://core2.bitcoincore.org/smartfee/fee_graph.html  ... for how high to make -paytxfee=0.whatever based on how long you're willing to wait for the first confirmation (that page graphs estimates from the latest&greatest fee estimation code from Alex Morcos that will hopefully be in the 0.11 Bitcoin Core release).

I'm now having full control of fees through:

• getbalance
• listunspent
• createrawtransactions
• signrawtransaction
• sendrawtransaction

Previous method was working fine but when change addresses (inputs) were too much I started spending more than 0.0001 BTC, complete chaos  
However now's everything ok with new functions

UPDATE: I'm talking about the following setting:



Is there any way to enable it by default for the use of sendtoaddress, sendfrom or sendmany on bitcoind?

[Amph]

couldn't you just set it with the custom option? what's the point of having that enabled by default?

Because I use RPC commands like sendmany on bitcoind server, that's why I need it set by default.

Why don't you just say "settxfee 0.0001"?

It's my understanding that doing so will do exactly what you're asking.

I've already tried it on Bitcoin testnet but still sending different fees, eg: http://tbtc.blockr.io/tx/info/08209cee9b4d506cd6c31f20a9e4274cafe4b3ed7ada51ee968feefc4c708822

I've only ever done this directly from the console - actually typing in the  settxfee 0.0001 rather than putting it into the conf file.

Then try sending a number of transactions and see what happens.

Well done mate, I try the command via console.. Fingers crossed!

Here's something from the .conf wiki page that should help:

 paytxfee=0.0001

settxfee and paytxfee both not working. I'm now trying mintxfee

Testnet requires fees too!
Then how do miners mine those bitcoins? 
Whatever, I've finally found the parameter: minrelaytxfee = <amount>

My understanding was mintxfee would do the trick. An older thread talks about how it was left out from the documentation to prevent tinkering much with it (source). But I'm not sure how 0.10 might be handling this differently.

Hold on, MultiBit client is doing the same with minimum 0.0001 BTC per 1.000kb, how come?

Thank you for your help, I didn't know that!

Yeah, thanks for that thread link. I didn't know that the Testnet didn't require fees. That makes sense I guess.
