text2pcap.exe should be in your ethereal install directory. It works
perfectly for Ethernet text. However I cannot get Token ring text to be
reimported. 

>From net/bpf.h:
#define DLT_EN10MB	1	/* Ethernet (10Mb) */
#define DLT_PRONET	4	/* Proteon ProNET Token Ring */
So I assume that text2pcap -l 4 should import token ring.

D:>tethereal -x -r trace.dmp | perl -ne "print if /^[0-9A-Fa-f]\d{4}  /" >
trace.txt 

D:>text2pcap -l 4 trace.txt trace2.dmp
Input from: trace.txt
Output to: trace2.dmp
Wrote packet of 62 bytes
Wrote packet of 160 bytes
<snip>
Read 23 potential packets, wrote 23 packets

D:\>tethereal -r trace2.dmp
Message: pcap: network type 4 unknown or unsupported
tethereal: The file "trace2.dmp" is a capture for a network type that
Tethereal doesn't support.

Does anyone have an ideas what's going here?

Alistair
