Verify FTP directly (without emulation) to the network card from the base OS (windows or linux). Make sure the to use the problem FTP file. Traceroute to the FTP server for later comparison. 3. If the FTP failed in step 2, then connect your laptop to the ethernet cable and try the same FTP. If it fails, I suggest you contact your network people (trying traceroute and ping) to discover where the problem is on the network. If successful, run traceroute to the FTP server and compare it to the previous traceroute to see if there are differences. 4. Run traceroute from zPDT OS and compare it to the previous traceroute for differences. 5. If traceroute is not showing a delay, then you may need to use PING with various packet sizes to very hops listed in traceroute. 6. I doubt that MTU sizes are causing this problem but stranger things have happened. You might want to verify them. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
