  1. Hello hyderabadhackers, Tell blackbird I said hello. I have been dealing with nessus for the last 24 hours or so; running it on BT5r3 as well. The machine is an older Acer Aspire 5734z dual core with an Atheros AR928X Wireless Network Adaptor PCI Express rev 01. I am receiving a “Form Error” at the flash add scan pop-up after parameter input. I have tried CIDR notation, IP ranges, and I paid mind to the possibility of a classful bug idea as well to no avail. I sent a support ticket. Do you have any ideas?
