Setting maximum speed of ethernet adapter

s_k

Hi, I need to set the maximum speed of network card programatically, eg. when my program is running on machine with 100mbps network card, I need to set it's maximum speed to 10mbps. Any suggestion helps much. Standa.

Most 100Mbps NICs are auto-negotiate. That is, if the server or target machine only runs 10Mbps or your router or hub is only 10Mbps, then the NIC will only negotiate 10Mbps on the hardware abstraction layer with no intervention from the OS, let alone your program. Now, if you are writing some proprietary device driver for an ethernet coffee machine or something and really need to do this, then I must admit I am out of my league. - Nitron

I admit it sounds strange, but I've FTP server that is too fast for weak machine (max. 32 MB RAM) with Win9x and on fast (at least 100mbps) LAN. The only thing that helps is to slow down the receiving/sending of data (to 10mbps). Hope you grasped ;)

Are you saying that the FTP program is consuming too many resources that you wish to use? If so, you might try lowering the priority of the FTP server. Then it won't consume CPU resources while you wish to use the machine. Tim Smith I'm going to patent thought. I have yet to see any prior art.

It may help as well, but not sure if it is 100% solution...

Well, such a machine I've at home, but it's commercial product and MUST be compatible even with the worst sh**s..;)

Maybe, but would you be happy to rewrite 50,000 lines of code due to this one bug, appearing only on very weak machines | win9x | fast LAN (at least 100mbps) ??? I think admin should be mor0n when running FTP server on such a shit...

eh - too fast? how can it be too fast? resources memory usage? have you tired other ftp sever versions maybe find one that is less resource hungry. easier way change the network card to a 10mbps only one

However it may sound strange, it's true. Yes, I've already tried other FTP servers - but they are much smaller than the our one. I think it's caused by that most of them is written in Delphi, whereas we wrote it in C++, and it's really difference... I remark again - it only appears on VERY weak machines, ONLY on Win9x and ONLY on fast LANs( at least 100mbps).
