sudo ./a.out config.conf api-tests

what does config.conf contain? (censor out the username/password)

[os-hall]

-------------- Added by myself
format=1
explanation: config is line based, 1st line must be "format=1", 2nd line is ignored (but must exist), line 3 contains the username, line 4 contains the password, line 5 contains the number of worker threads you want (higher count should increase IO speed, and it does not depend on how many CPU cores you have.), line 6 contains the path to the sector index file, line 7 contains the nbd device to use (/dev/nbdX), and line 8 should not exist. a username or password or filepath containing newlines is not supported.
os.hall@me.com
UPu3EtUnYt
3
sectorindex.sec
/dev/nbd1

after looking at the config file i notice its important to not have a carriage return on the last line.

i did believe i was able to open a connection and follow the remainding steps, however i have no luck browsing after i mounted the cacdrive to my mount point. i was not able to copy a file as a user or root.

i will look at my permission settings to see if there's any user settings i can set or change

@os-hall can i check the system personally? can you try contacting me on facebook or discord? contact info at https://stackoverflow.com/users/1067003/hanshenrik?tab=profile

[os-hall]

Sure. I can give you the system logon info. It’s just a sandbox for me to play around with. I was hoping to build an ansible role or bash for mounting this drive on other systems. 104.167.111.83 olive ripe

i guess what happened is that cacdrive was started prior to this, and crashed, and did not manage to clean up properly, and /dev/nbd1 was left in a... broken state.

easy solution: reboot (this should make nbd1 work again) or switch to /dev/nbd2 (you have 12 btw, /dev/nbd1.../dev/nbd12)

alternative solution: write a little program that opens /dev/nbd1 and runs

auto fd=open("/dev/nbd1",O_RDWR);
ioctl(fd, NBD_CLEAR_SOCK);
ioctl(fd, NBD_DISCONNECT);
close(fd);

, that should do the cleanup manually and make /dev/nbd1 usable again, in theory..
