If you are looking for bandwidth control, you can use the pureftpd (found on the 3rd party CD) to replace the default QNX ftpd server.

by the way,what’s the default value(maximal and minimal rate) by using ftpd?

Based on this article, China is blocking sourceforge.net and pureftpd.org/ is hosted on sourceforge …

You should consider using some of those open proxy servers to by pass those blocks.

sir,I have read it and try to use “pure-ftpd -T 256:64 &” to control the bandwidth of ftp,then I download file under windows from target,but I see the bandwidth is more than 4M/s,not small than 256k.why?

ok, I just read that README, and here is what it says about bandwidth control:

So basically you need two things for bandwidth throttling:

compile the pureftpd with --with-throttling option.
run the pureftpd with -T (or -t) option.

You mentioned -T, but have you compiled it with --with-throttling ?

noc · December 2, 2004, 5:25pm

Isn’t that documented in the same README file?

please help me,noc

I believe xtang compiled the version on the 3rd party CD. You can check with him to see if he made any QNX specific patches, if not, you can simply run the ./configure with desired options as documented in README, and then “make” and “make install”. All standard stuff.

I have install “pure-ftpd” using 3rd party CD,but I can’t find the file “configure”,why?

xuyong · December 27, 2004, 1:21am

I can’t find the answer now,who can help me?

noc · December 28, 2004, 12:24am

You need the source code of the pure-ftpd and “configure” is in there.

Look for the file “src.zip” on the CD. It should has the source code for all program, including pure-ftpd.
