Samba not working

krel · 2019-12-15 21:42:46

Hey oh!

I'm having issues connecting to my samba share... I've combed the internet for solutions, and nothing so far.

I'm looking for a public share, with no password required.

Firewall issues?
Edit: does the nobody user exist?

Yes it does:

[krel@namcle ~]$ cat /etc/passwd | grep nobody

nobody:x:65534:65534:Nobody:/:/usr/bin/nologin

as well as a group:

[krel@namcle ~]$ cat /etc/group | grep nobody

nobody:x:65534:

I'm having issues connecting to my samba share.

Please be more specific here. One pot. issue at hand is that the client max protocol is set to NT1, ie. the wannacry protocol that's deprecated everywhere and I'm not sure whether recent windows versions didn't remove it altogether (but you will have to explicitly enable it for sure, maybe install some additional software)

krel · 2019-12-17 20:50:01

I've removed the NT1 line from the config with no luck.

More specifically, I need help addressing these errors from /var/log/samba/log.smbd

Any thoughts? I didn't have any luck searching the web for answers. I'm not sure if those are generic errors or the actual source of my problem.

We still don't know about:

I'm having issues connecting to my samba share.

From what kind of client and what is the actual issue (symptoms, error message, …)

My next best blind guess would be https://wiki.archlinux.org/index.php/Sa … ermissions

krel · 2019-12-23 03:33:50

Sorry, I'm still struggling with this. Connection to samba doesn't work with Windows, other Linux boxes, iPhone apps I've used in the past for accessing shares.

Basically, I can see the share listed... But when I access it I get the errors like:

Unable to access location
Failed to mount Windows share: Permission denied

I'm not sure if it's a permission thing... I'm pretty sure they are all in check

sudo chown -R 775 /home/krel/media/share/

Is there an easy comandline mount command I could use to mount the share to see some output?

Thanks,
-KV

Try smbclient https://www.tldp.org/HOWTO/SMB-HOWTO-8.html and report the compelte I/O (what you wrote and what the system replied. You may obfuscate directory names, but in a consistent way and please highlight non-ASCII paths)

krel · 2019-12-26 21:48:29

"share" is what I'm trying to access.

[krel@namcle ~]$ /usr/bin/smbclient -L namcle

I'm having a few issues... Like even though I add guest account = nobody it still seems to prompt for a password when I attempt to login. I'm not sure if my user accounts are all bunged up, or if my permissions are all effed up
