This week I was experimenting a lot issues with my Internet connection in my house. The ISP installed a few years ago the following device: THOMSON TG585 v7.
I checked the logs from the Thomson device, and I could see these:
| Sep 13 19:00:39 | CONFIGURATION mbus atomic sync successful |
 |
 |
| Sep 13 19:00:30 | LOGOUT User logged out on TELNET (64.20.227.134) |
 |
 |
| Sep 13 19:00:23 | LOGOUT User logged out on TELNET (64.20.227.134) |
In the last example was an scan that I did from www.mxtoolbox.com where I could see the telnet and http ports open. So I decided to close them because they are related with the device management.
Then I found this link: https://groups.google.com/forum/#!topic/demon.service/uFtKsZZCx5g
And the commands to solve this situation were:
First: login via telnet
service system ifdelete name=TELNET group=wan
service system ifdelete name=HTTP group=wan
service system ifdelete name=FTP group=wan
Then: Rescan from the WAN side and you should feel a bit happier.
Finally:
saveall
And that's it, the administration is secured.
I hope this could be helpful for you.
Regards.
