I have a problem which has the following symptoms:
When copying files to an iBay, the transfer fails after a random length of time (5 seconds to 15 minutes) with a 'network resource not found' (or similar) message. On the first client PC using Windows 98, I lose all IP networking (ie unable to ping server and other client PC's). On the same PC using Windows 2000 I get a BSOD with a stop error. On a second client PC using Windows 2000, I get the 'network resource not found' message and loss of IP also.
The network has been working fine for the last 2 years running MS software, so I know the server and client hardware is probably ok.
I am using e-smith 4.0.
All PC's are connected through a single 10/100 hub.
Any assistance would be appreciated.
Cheers,
Gary

There is obviously some problem with Windows 98.

There is obviously some problem with Windows 2000.
The symptoms sound as though there is a problem in the networking stack, or maybe the driver.
If you identify the problem, please let us know.

I have since changed the MTU to 576 on all machines. Everything with the Samba sharing _appears_ to be working OK now. (Only time will tell!)
The only side effect I have noticed is that when copying large amounts of data, the Internet connection via dialup virtually stalls. When I stop copying files, the Internet runs at full speed again.
The server machine spec is an AMD K6-200 with 64MB RAM and 20+GB of storage. I believe this meets the spec. Maybe it's a simple case of the local net traffic swamping the Internet traffic?!?

Gary,
Just as a side note. You can also experience these same problems with your network cabling. If your cables are constructed as CAT5 10/100 cables and you have a kink or bend in the cable, the hub/switch will sense the cable as 100megabit capable and intermittently drop the connection when it does not perform at that rate.

Thanks for the suggestion Steve. I have rechecked the cables, and all is OK. Also, it was working fine prior to loading up e-smith.
The problem about slow internet access is becoming quite acute now. I have left it for a few days in case it was an ISP or general Internet thing, but I can access the net on a slower 33.6K modem to the same ISP on one of the client boxes, and it hums along quite nicely. When I go back to the e-smith box using the 56K modem, net access is woeful and even stalls. I will load up the old Win95 setup (I am loathe to admit to a crappy MS setup being better than e-smith) to see if it is a 56K modem issue, but I doubt it, as the setup was fine previously.
I am also having problems with DNS. The named daemon is barfing an error message about being unable to access /var/run/ndc. Could this be part of the problem?
Cheers,

Hi All,
The solution of the MRU _may_ be a bit of a furfy! (My apologies)
I decided to start with a clean slate and install 4.1.1 from scratch instead of over the top of the 4.0 installation. What appears to happen is a newly created iBay will develop the symptoms mentioned earlier if the system has not been rebooted. I have tried stopping and restarting the SMB daemon, but the problem persists until I reboot. Once rebooted, it appears to work OK. (Will keep an eye on it)
The second problem of lousy Internet access speed via dialup I am still investigating. At least it is not stalling now. The DNS problem is now also fixed. I suspect I should have done a fresh install and not an uprade! (Hindsight is 20/20 vision!)
Cheers,

The upgrade process is designed and tested quite extensively to be be equivalent to a fresh install. There should be no need to do a fresh install. If anyone finds this not to be true, they should report details to bugs@e-smith.com.
Of course, if there have been any non-standard modifications to your system then there is no guarantee that the modifications are compatible with the upgrade process.
