Hi Amit,

I have tested that half a year ago or so. I do not have to old
version available (I only have the svn version...) but I have
reproduced the problem.

Can someone look at the problem, since I have not looked at that code before...

Best regards
Michael

Hi Michael,
Thanks for the quick response. I am using Ethereal 0.10.9 version. Could you please tell on which version of ethereal support for FIFO works fine?

Regards,
Amit Dang

Hi Amit,

this is a bug in ethereal. It is working with older versions and has
to be fixed.

Normally you can run

tcpdump -w /tmp/fifo

and

ethereal -i /tmp/fifo

and it works.

Best regards
Michael

Hi Michael,
I tried reading from FIFO but it fails.
Tethereal is able to show the captured data using "tethereal -i
/tmp/datafifo" but ethereal is not able to display the captured
packet.
For detailed information please refer following mail that we posted on
ethereal-user list (subject: [Ethereal-users] Tethereal can, Ethereal
cannot)

------------------------------------------------------------------
I am using named pipes (FIFO) to read captured data. My problem is
that Tethereal is able to show the captured data using
"tethereal -i /tmp/myfifo"

but ethereal is not able to display the captured packets. Am using
following command:
"ethereal -i /tmp/myfifo -kl"
Ethereal just says that theres nothing to display as no data has been
captured. I can confirm that its reading the right FIFO as it does
identify a wrong formatted data, whenever I try to write some junk
data (read non-pcap conforming data) on the pipe.

Following command is being used in both the above cases to write
captured data on FIFO
"cat packets.pcap > /tmp/myfifo" /* myfifo has been created
using "mknod p"*/

Ironically, the file "packets.pcap" has been created after capturing
data on my host's network interface using *Ethereal* itself.
