Pushpool - Tech Support

[jgarzik]

How do i send "listtransactions" to it? I am using Ubuntu Server 11.04 w/ bitcoind.  How do i send queries to the daemon? Im a linux n00b

This has nothing to do with pushpoold.  pushpoold is just an HTTP proxy, sitting between mining clients and bitcoind.

All commands such as listtransactions go straight to bitcoind as usual.  'getwork' is the only JSON-RPC method supported by pushpool.

Theres probubly a better way but for simplicity i use a php bitcoin library to query bicoind

This is because when starting pushpool you need to specify the path to the config.

pushpoold --config=/mypath/to/config/somefile.json

oh...I thought it was something simple as that. thanks ;-)

Finally I had time to try it. Still not working...but it seems it can at least find the file...because if I enter a WRONG path I get "config file: no such file or directory" instead of "JSON parse failed".

Download a fresh coppy of server.json I would say you have an error in JSON file.

I copy and pasted the code for server.json thats posted at the start of this thread. Then I added my data. Where can I download a working server.json?

I would try copying and pasting again, and make sure you include both { } when copying and pasting one missing semi-colon, hyphenation, etc, etc json dosn't like this

Thanks Xenland! I found the problem. When I entered my ip-adress I accidentally deleted the closing ". Its working now :-)

Hello,

could someone please give me the share(solution) hash for an actual block that was found.
And one other question: why is pushpoold quiting/not starting without any errors?
I have the latest pushpool version.

the newest pushpool has a bug where output dosen't display. There's a fix for it on the previous page and an easy delete greather than sign then replace it with a less then sign or somthing like that.

[redshark1802]

Thanks i already had that version, the problem was that the pid was not removed properly.

Do you have a valid for an actual block?

It seems pushpool is not listening on any ports for me.
I get this:

"[1308747727.006541] Listening on host :: port 8347
[1308747727.006620] Listening on host :: port 8344
[1308747727.007214] Listening on host 127.0.0.1 port 8338
"

Where it says "host ;;" I had actually entered an ip adress in the config file.
According to nmap none of those ports is actually open and beeing listened on.

What am I doing wrong?

You should only connect to *:8347 with your miner.
Did you nmap on the localhost or the remote and what parameters did you use?
Try "nmap -sS -p 1-6000 -v <targetip>" from an remote host.

I nmaped from the remote. I now get 8332 and 8333 as open ports, but none of the pushpool ports (if using -p 1-9000).

Please post your server.json config, preferable on pastebin.com and I recommend closing 8332 and 8333 via iptables.
For an standard iptables installation type:
iptables -A INPUT -p tcp --dport 8332 -j DROP
iptables -A INPUT -p tcp --dport 8333 -j DROP

linux noob here.

installed a fresh copy of ubuntu desktop on VMware. Jansson was installed successfully, but i can't get libmemcached to install.

i got an error when using ./configure, and make does not work.

Code:

configure: error: "could not find memcached binary"
pool@pool-virtual-machine:~/libmemcached-0.50$ make
make: *** No targets specified and no makefile found.  Stop.

[frizzl]

A few requirements were missing from the original post try this:

sudo aptitude install libmemcached-dev

then try ./configure

again
