All,

 

I am working on a project that involves analyzing HDLC data that has been captured from a SONET link.  Currently, I have a small program that performs a 16-bit read from a SONET PCI card and I am trying to feed that data into tethereal.  We are planning on developing a module so that the actual HDLC data will be separated into an 8-bit register.  I have tried saving the data to a file and then handing the file off to tethereal, but it does not recognize the capture format.  I have 2 questions –

 

1)      How do I put the file into a format (capture format) so that tethereal will understand?

a.       The problem with that is that I will be handing tethereal 1-byte size files on a continual basis.

2)      How can I pipe the data to tethereal before putting it in a file?

 

The documentation says that tethereal supports Cisco HDLC.

 

I may be posting this to the wrong list, so I apologize in advance if that is the case.

 

Thanks for entertaining my questions.

 

Britt
