Below I have checked all of those i'm not sure if the owner is necessarily ok but the rest seems definitely ok. 

harvey@samsung350 /var 
$ ls -l /var/log/sshd.log 
-rw-r--r-- 1 SYSTEM root 4489 May 13 03:41 /var/log/sshd.log 
So it hasn't been written to recently 


harvey@samsung350 /var 
$ tail -n 1 /var/log/sshd.log 
/var/empty must be owned by root and not group or world-writable. 
ok that's an old error 


harvey@samsung350 /var 
$ ls -ld /var/empty 
drwxr-xr-x+ 1 SYSTEM root 0 Aug 29 2014 /var/empty 
permissions are fine I guess.  I'm not sure if owner should say root. 



Permissions for ~/.ssh and its contents is absolutely correct.  I have no ~/.ssh/authorized_keys file though that's ok not to have that. 
harvey@samsung350 /var 
$ ls -ld ~/.ssh 
drwx------+ 1 harvey None 0 Jun 7 01:38 /home/harvey/.ssh 

harvey@samsung350 /var 
$ ls -l ~/.ssh 
total 19 
-rw------- 1 harvey None 1679 Aug 29 2014 id_rsa 
-rw------- 1 harvey None 399 Aug 29 2014 id_rsa.pub 
-rw------- 1 harvey None 1679 Sep 4 2014 id2_rsa 
-rw-r--r-- 1 harvey None 870 Jun 6 23:07 known_hosts 
-rw-r--r-- 1 harvey None 361 Sep 5 2014 known_hosts.bak 
-rw-r--r-- 1 harvey None 867 Sep 8 2014 known_hostsb 
-rw-r--r-- 1 harvey None 38 May 21 06:47 oldconfig 

harvey@samsung350 /var 
$ 


I guess my server keys permissions are ok. I'm not sure if owner should be root 
harvey@samsung350 /etc 
$ ls -l ssh_* 
-rw-rwxr-- 1 SYSTEM root 1574 Jun 7 01:35 ssh_config
