Users never enter the secret so we use a 32 char random string of characters for the password 3) Don?t allow connections to port 80 from off-site. 4) Make sure your OS and SSH/SSL is updated packages are updated. Contact your carrier and ask about any possible fraud detection. Verizon SIP service has that feature. I don?t think Level 3 has. Don?t know about CenturyLink. I also recommend locking down the system very tight with IP tables ? only allow whitelisted traffic rather than only blocking blacklisted traffic. Fraud is a constant issue for everyo...

I charge my customers through PayPal, but recently faced a fraud which previously had only heard about. Somebody registered a few accounts, paid online with paypal (as my service is only prepaid) and started making expensive long distance calls. In fact the IP registering the accounts was from Florida, and IPs making calls were from Africa. After about 20 minute...

...ut as a single scan. It must have been posted, because I have at least ten IP addresses now that were placing calls via the same peer. They are from all over the world. So what is the accepted procedure? I'm in the US Virgin Islands, so do I go to the FBI? Police? Is their some telecom fraud body to report such things to? Does any one ever get any relief from such events? I'm basically sick to my stomach right now. j

Hi, in case, anyone is interested... I have started compiling a blacklist of hosts and networks from which SIP fraud attempts occur. My criteria currently are: To block an IP: - Minimum 3 attacks within one week from the same IP To block a network: - Attacks from minimum 3 IPs from that network within 2 weeks Common criteria: - Provider does not react to complaints OR - Provider sends autoreply but attacks don...

The loss of communication to USB devices has been discussed before on this list.

Charles Lepple was instrumental in the thread I'm thinking of. Roger's suggestion of a more intelligent cron job sounds
