It is observed ID field of IP header in ping packet (Echo request) is always 0. I confirmed this on kernel 2.4.18 and 2.4.21. My colleague also confirmed this is fixed in kernel 2.5.74. I hope this is fixed in next next 2.4.x release. I am sorry if this had been fixed already. #I am not member of this ML. #If you need any further information, please CC me. Regards, Kohei.
