How to view the contents od a device file ??

Ramesh.K.R. — Wed, 16 Oct 2002 06:21:35 GMT

Hi,

Is there any tool/way to view the contenta of a device file like /dev/tty0p7 ?
Let me give some background of our problem. We are trying to pass some serial data from one hpux m/c to another through a device. We are not able to see any data on the destination m/c. For this, we want to check wheather any data is received by the device file of the source m/c.
Any help/pointer is highly appreciated.

Thanks & Regards,
Ramesh.K.R.

Ramesh,

Did you try a simple 'cat < /dev/tty0p7' ? It should work.

I think this is a case for netfmt (see man netfmt). This will log all packets in and out of your server. It will produce a huge logfile so dont run for too long, the trick is to filter out only what you want (by ip, user, tty).
