I generally do not enjoy asking off topic questions, but I really need to know this and it is security related. How can I keep a log file of every single byte sent and received over a modem line at the originating computer (Windows 95 / PPP Connection). I do know that some/most comm. programs provide for this type of logging, but what if I'm not using such a program, and instead I use Microsoft's Dialup Networking?
One solution to really get _every byte_ sent over a serial line, regard- less of the protocol used, is a black box inserted into the line. I know one product (mail me if you need the info, the name of the company escapes me at the moment) that can log all traffic to another serial line or via syslog, and can send SNMP traps or alert a pager when certain (programmable) strings appear in the data stream. I quite like this approach for certain setups; it is very different from the common software-only logging, which makes tampering with logs unlikely to impossible, depending on the actual setup. -Martin -- Martin Freiss, MF194 | freiss.pad () sni de | http://www.rmi.de/~marvin Siemens Nixdorf, CC IT Networks, Solution Team Internet/Intranet Half male, half e-mail.
