Problem partially solved.. Using a D-LINK DGE-530T with the syskonnect skge 64-bit driver, instead of using the inbuilt realtek NIC in the opensolaris box and now samba works great, 25 sec to copy a 1GB file.
I've heard some other posts where realtek network chips were causing probs, think I'll stay away from them in the future. Re ping exchanges, this does indeed show up the differences. Pinging from the opensolaris to the linux laptop works perfectly with ping data sizes up to the IPV4 limit (65507). This works with both the realtek NIC and the dlink NIC. Pinging from the opensolaris to the win32 desktop the maximum ping size I can get to work is 1472. As greater size results in 100% packet loss. This is also with both NIC's. Anyway I at least have the samba functionality I need. Would be nice to sort out why the unix machines are fine with each other but unix<->win32 seems to have much more problems at a basic networking level. It could indeed be bad drivers etc. Mark On 7/20/07, Steve Platt <[EMAIL PROTECTED]> wrote:
Mark, It might be worth checking that you can do large ping exchanges between the affected systems ... eg in solaris try /usr/sbin/ping -s clientpcname 64000 This sends several ethernet frames almost "back to back" and can show up duplex problems as well as driver/buffering problems (common in PCs).
