I set up an SMB server on my Mac by going to System Preferences > Settings > Sharing and enabling File Sharing. Afterwards, I tried to access it from my Arch Linux laptop. It asked for my password, as I expected, and I enter my Mac's login password. The dialog keeps showing however.
Using the terminal and entering
smbclient -L 192.168.0.64 yeilds the following output on both my laptop connected to the network, as well as in an Arch Linux virtual machine running on my Mac:
mike@ArchLinux > ~ > smbclient -L 192.168.0.64
smbclient: Can't load /etc/samba/smb.conf - run testparm to debug it
Enter mike's password: <I enter my Mac's login password here>
session setup failed: NT_STATUS_LOGON_FAILURE
Using PCManFM as my Linux file manager, going into
network:/// shows "Windows Network". Going into there links me to
smb:///, which then shows "Failed to retrieve share list from server: No such file or directory"
