TNFSD Directory Listing Vulnerability

[E474]

Hi @mozzwald,

 

  Thanks very much for your reply, the errors in the tnfsd.service file were causing the problem. When I changed them, I could start up the server correctly, and it would happily serve images to the FujiNet-PC:

pi@pi3bp2:~ $ more /etc/systemd/system/tnfsd.service 
[Unit]
Description=TNFS Server
After=remote-fs.target
After=syslog.target

[Service]
User=root
Group=root
ExecStart=/usr/local/sbin/tnfsd /tnfs -c tnfs

[Install]
WantedBy=multi-user.target

 

I had to do a little bit more than just a systemctl start:

pi@pi3bp2:~ $ sudo vi  /etc/systemd/system/tnfsd.service 
pi@pi3bp2:~ $ sudo systemctl start tnfsd
Warning: The unit file, source configuration file or drop-ins of tnfsd.service changed on disk. Run 'systemctl daemon-reload' to reload units.
pi@pi3bp2:~ $ sudo systemctl daemon-reload 
pi@pi3bp2:~ $ sudo systemctl start tnfsd
pi@pi3bp2:~ $ sudo systemctl status tnfsd

But everything works correctly now!
