I have a home network with wifi that is password protected. On my home network, I have a file server with a password protected Samba share. The share itself is protected because my network has multiple machines with multiple users and I want to make sure only I can access this share from whatever machine I'm using at the time (sorry for stating the obvious, but I want to head off responses of, "You're on a home network and your wifi is already pw protected, so why do you need pw protection for the share itself?" etc).
Currently, this is how I mount my Samba shares (note, the part that's relevant to my question is
mount -t cifs //myserver/myshare /media/myshare -o uid=myunixuser,gid=myunixgroup,credentials=/home/myunixuser/.smbcredentials,iocharset=utf8,sec=ntlm,file_mode=0600,dir_mode=0700
So far, so good; however, I've read several articles about security types and why NTLM is not recommended, yada yada (see article "NTLM’s time has passed"). I've googled "ntlm vs ntlmv2 vs kerberos" and tried to learn more by reading the Wikipedia article about NTLM and the Ubuntu man page on this topic, but it's not quite registering for me.
I feel like most documentation out there is intended for network admins, and I'm more of a weekend warrior. In general, I gather that NTLMv2 is preferred to NTLM, same with Kerberos, but that doesn't mean I should automatically choose v2 or Kerberos because not all clients support them. Sooo, what the heck? Can anyone dumb it down for me? Even if I stick with NTLM, I just want to understand what's the deal with these different security options. Please let me know if I'm thinking too hard about this. Thanks.
