The systems are at different kernel levels Two systems each running XUBUNTU 16.04. When ufw (firewall) is disable, both give a full list of shares, some of which are Ubuntu while others are Windows XP. If the ufw firewall is enabled, one of the systems continues to give a list of shares, the other one does not. - Both are current per the software updater - The working one was brought to 16.04 two years ago (kernel is 4.4.0-133-generic) - The failing one was recently installed from a downloaded DVD image (kernel is 4.15.0-32-generic) then configured using the working one as a reference for configurations etc.
ufw shows the following rules, which are identical except for order
3389 ALLOW 192.168.1.64
3389 ALLOW 192.168.1.65
3389 ALLOW 192.168.1.66
3389 ALLOW 192.168.1.67
3389 ALLOW 192.168.1.68
23/tcp ALLOW Anywhere
Samba ALLOW Anywhere
23/tcp (v6) ALLOW Anywhere (v6)
Samba (v6) ALLOW Anywhere (v6)
A probably unrelated curious thing is that any time I enable the ufw (firewall), my remote (xrdp) session freezes but only on the system that returns nothing to smbtree with firewall enabled.
