Hello,
We are upgrading at last from old Fedora Core 3 to Fedora 8 and Ubuntu 8 workstation, both with the latest updates. We have an application that runs fine under FC3 but that apparently now has a TCP/IP socket problem under the new OS's. We get the same problem under both new OS's.
Our client application on a PC makes a socket connection to the Linux machine, which we're using as a server. The socket connection takes the usual several packets. But then, literally about 1 millisecond later, the Linux machine sends a reset that closes the connection. We did not get this reset before.
We've captured lots of packets using Wireshark in Windows and tcpdump in Linux. The firewall is turned off in Linux, which we've verified using ufw and iptables.
What change in Linux could account for this problem ? How do we fix it ?
Thank you in advance for your help.
