Cannot run bitcoin-cli

[notooth]

Hi everyone,

I cannot get the bitcoin-cli work. Here is what I did:

Content of bitcoin.conf:

daemon=1
server=1
rpcuser=myusername
rpcpassword=mypassword12345
rpcport=8332
rpcconnect=127.0.0.1

$ bitcoind
Bitcoin server starting

$ bitcoin-cli getblockchaininfo
error: couldn't connect to server: unknown (code -1)
(make sure server is running and you are connecting to the correct RPC port)

Can anyone help?

You have setup a password for your RPC connection, that means you need provide the same username/password to run bitcoin-cli in command line. You just simply remove your bitcoin.conf or rename it then shutdown bitcoind and start it again.

[move bitcoin.conf to another name]
bitcoin-cli stop
bitcoind --daemon

[wait a while when the program warm up]
bitcoin-cli getblockchaininfo

[notooth]

I renamed bitcoin.conf to bitcoin.conf1, reboot the system, and I still got the same error:

$ bitcoind --daemon
Bitcoin server starting
[The server started immediately]

$ bitcoin-cli getblockchaininfo
error: couldn't connect to server: unknown (code -1)
(make sure server is running and you are connecting to the correct RPC port)

[mattxlee]

Maybe you need to check debug.log and see what happened.

I renamed bitcoin.conf to bitcoin.conf1, reboot the system, and I still got the same error:

$ bitcoind --daemon
Bitcoin server starting
[The server started immediately]

$ bitcoin-cli getblockchaininfo
error: couldn't connect to server: unknown (code -1)
(make sure server is running and you are connecting to the correct RPC port)

Take a look at your debug.log.

[mocacinno]

execute following commands, and post the outcome(exept from the last command, you'll have to use ctrl-c to stop it), remove the password from the bitcoin.conf output :

Code:

ps -ef | grep bitcoind
netstat -tulpn | grep 8332
tail -n 100 ~/.bitcoin/debug.log
id
who
whoami
which bitcoind
which bitcoin-cli
cat ~/.bitcoin/bitcoin.conf
tail -f ~/.bitcoin/debug.log

normally, you do not have to enter any credentials when using bitcoin-cli, as long as you're using the same user that was used to run the daemon. Unless, offcourse, you changed your bitcoin.conf AFTER you started the daemon. In this case, the daemon will run with the old bitcoin.conf parameters, while bitcoin-cli will use the new parameters.

If you enter daemon=1 in your bitcoin.conf, the startup parameter --daemon is no longer needed (but i does no harm).
If you use the default rpc port, there is no need to redefine it in your bitcoin.conf (but it does no harm)

I forgot to mention that the OS is OpenBSD. Here is the output:

$ ps -ef | grep bitcoind
ps: unknown option -- f

Sorry, i tought you were running linux (not many people on this forum run openBSD, so i wrongfully assumed you ran linux), but most of my commands don't work on BSD... I'll update this post in a couple of minutes with compatible commands.

What i already see is that since you first posted a debug.log, it seems your daemon stopped synchronising. My best guess would be that bitcoind was killed for some reason.


Edit
The FreeBSD (hopefully also openBSD) alternative of my question:

Code:

ps -auxw | grep bitcoind
sockstat -l | grep 8332
dmesg

Disclaimer: i didn't have an openBSD machine running atm, so i didn't test out these commands... They can't harm your system, but it's possible they won't work due to invalid parameters...

[notooth]

The output exceeds the maximum allowed length of this forum, so I upload the output to this file:
http://www.mediafire.com/?1v9640mgq9a9w

[mocacinno]

The output exceeds the maximum allowed length of this forum, so I upload the output to this file:
http://www.mediafire.com/?1v9640mgq9a9w

Seems like sockstat doesn't exist on openBSD either  
Doesn't matter, this is all we need to know:

$ ps -auxw | grep bitcoind
notooth   6491  0.0  0.0   308  1308 p0  S+p    4:08PM    0:00.00 grep bitcoind

bitcoind is no longer running... I already had the gut feeling we would see this output, since there were no new lines in your debug.log

However, as to why it stopped... That's a different question... I don't see anything significant in dmesg.
Is there still space on your disk?
df -g => look for the partition that holds your home

Other than that, you can look at the system logs, and see if there's something in there

Or, maybe you can run bitcoind on the foreground in a different terminal, and see if there is output when/if it's killed (just put a # in front of daemon=1 in your bitcoin.conf and start the daemon without the --daemon option)

[achow101]

Use multiple terminals and remove daemon=1 from your bitcoin.conf file. When bitcoind crashes (probably a segmentation fault), the error will be printed to the terminal that it is running in. With daemon=1, we won't be able to see what that error is.

Also, did you compile this yourself? If you did, what exactly were the commands that you ran? If you did, did you make any changes to the code, and if so, what were they?

[notooth]

I did exactly the steps in bitcoin-master/doc/build-openbsd.md. I did not change any code. Here is the output on the terminal:

$ bitcoind
bitcoind(67438) in free(): chunk is already free 0xdc658915450
bitcoind(67438) in unknown(): bogus pointer (double free?) 0xdfdfdfdfdfdfdfdf
