Title: How to set datadir mode 750 and files 640 without sysperms Post by: Crypto Carabao Group on July 02, 2019, 03:43:03 PM If we don't use sysperms=1, bitcoind sets datadir mode to 700 (rwx------) and files to 600 (rw-------) including auth cookie.
Does anyone have good bitcoind configuration to set datadir 750 (rwxr-x---) and files 640 (rw-r-----), with sysperms=0 (default) ? We are trying to figure out this: https://github.com/JoinMarket-Org/joinmarket-clientserver/issues/361 (https://github.com/JoinMarket-Org/joinmarket-clientserver/issues/361) Title: Re: How to set datadir mode 750 and files 640 without sysperms Post by: jackg on July 02, 2019, 05:07:01 PM You've not given us enough information.
Presumably you're trying to do something with file permissions on the file system? What operating system are you running and why are the files made with a file permission that the daemon can't access? 700 i know as rwx------, why is it doing this - surely if it can make something with that permission then it already has enough permissions to edit and read the data?

Thank you. That's right about group permissions need, as in the OP link.I think his project needs group permission (where as bitcoind only give permission to user) The mention of sysperms is right in Running Bitcoin wiki (https://en.bitcoin.it/wiki/Running_Bitcoin) Disabling chmod is a good idea, but with sysperms=0 (default) bitcoind will create all new files mode 600, including the auth cookie and new blockchain data. Possible to mitigate with scripts, but messy and error prone, and could still cause problems for other apps that need real-time new blocks data, such as Armory for example.
