Sniffing the data from a user session

[Alon Jacob]

Hello all,

Can anyone tell me if there is a freeware that allows me to remotly watch a user session (like VNC or PCANYWHERE on windows platforms)?
Alternatively, if you know of some freeware that will "sniff" and show me what carachters are being sent and recieved fron and to my ALPHA server (either to run from the alpha or my PC).

Thanks.

Hi,

I do not believe there is something similar available for OpenVMS.

If the alternative of capturing the output of user sessions is enough for you then could implement a USER_LOG account as described in the OpenVMS Guide to Security ("Logging a user's session"):

Or if you are interested in developing a key logger yourself then you could have a look at the LOGGER source-code (pseudo-terminal) from Forrest A. Kenney. I have attached the ZIP file to this message because I do not know anymore where I got it from.

Best regards,

Dave Laurier

And now I also found where I got it from, Hunter Goatley's fileserver:

But I would trace the network packets with eg tcptrace for a 1-shot snif.

As Win says TCPTRACE can be used to capture data on an IP connection.

Ethereal, available free at http://www.ethereal.com/ can read the VMS TCPTRACE file formats and allow you view a session within a large capture. If I ever meet Marc Milgram who added this functionality, I owe him a dinner and beer.

Beerware: If it works you can buy me a beer. If it doesn't work buy me a pitcher and I'll see what can can be done about it.

I used to use 'Supervisor Series' from the Freeware CD in the old days on VAX, but I don't know if there is a verion that works on Alpha.

Wonder if there is a T software piece allowing to duplicate X-windows output ...

Ethereal (on Windows or Linux) will probably do the job. It allows you to gather alll network information and store it in a file you can examine off-line.
