Almost there ! CPU Dual Xeon Test

Technical Support
1

I’m running a test via Windows 10 Bash. I will write up a tutorial post when I succeed.

I’m at running this (./src/zcashd -daemon), but I get this :

root@PRECISION:~/zcash# ./src/zcashd -daemon
Zcash server starting
root@PRECISION:~/zcash# Error: To use bitcoind, or the -server option to bitcoin-qt, you must set an rpcpassword in the configuration file:
/root/.zcash/zcash.conf
It is recommended you use the following random password:
rpcuser=bitcoinrpc
rpcpassword=7y624eKZyhjENndmEZ52QuaQKWg6MsenmYhfsuJKdGRY
(you do not need to remember this password)
The username and password MUST NOT be the same.
If the file does not exist, create it with owner-readable-only file permissions.
It is also recommended to set alertnotify so you are notified of problems;
for example: alertnotify=echo %s | mail -s "Bitcoin Alert" admin@foo.com

This is my zcash.conf :

testnet=1
addnode=betatestnet.z.cash
rpcuser=bitcoinrpc
rpcpassword=4hiZX4reHpMQNKXuSsTXRREjYPQkCFZCQY9m82C6eNzj

This is located here : \root\.zcash

This windows just stays there … (Screenshot by Lightshot)

What’s the next step ?

If I run ./src/zcash-cli getinfo I get this :

error: You must set rpcpassword=<password> in the configuration file:
/root/.zcash/zcash.conf
If the file does not exist, create it with owner-readable-only file permissions.

The file is there : Screenshot by Lightshot

The directory structure seems to be fine : Screenshot by Lightshot

Any idea ?

Ok, so I tried this

$ ./src/zcashd -daemon -debug -printtoconsole

And I got this :

Zcash server starting
root@PRECISION:~/zcash#

Could it be related to any wallet already running (Bitcoin, Litecoin, Peercoin ?

Did you build zcashd in the Bash On Ubuntu On Windows subsystem, or natively with something like mys2?

I’m curious because I’ve been working on an msys2/mingw64 build.

Thanks!

I did it on Bash On Ubuntu On Windows subsystem

very possibly, BTC and zcash use the same rpc ports, but zcash is still on a testnet, which has different ports than a production bitcoin installation. I wouldn’t run zcash on the same box that has another wallet on it, that…could be bad.

nah, atm the testnet’s definitely localhost:18232, can talk to it with json::rpc
u hafta open firwall ports …
I did these for ubuntu:
ufw allow out 18232/tcp
ufw allow in 18232/tcp
ufw allow out 18233/tcp
ufw allow in 18233/tcp
ufw status

I found the problem, you cannot create the .conf file via windows, ubuntu won’t recognize it. Instead I edited a .log file and with the conf info and renamed it in the console. It worked !

… got a 0.06 hashrate with dual xeon …
