I had the same problem, and I changed the source code, the line

    sys_mmap 0,dword [sts.st_size],PROT_READ|PROT_WRITE,MAP_PRIVATE,ebx,0


to

sys_read ebx,cfg,dword [sts.size]

and add almost at the end of program

cfg resb 8192

System call mmap is different on Kernel below 2.4 and above, and 
therefore, without my patch, ftp daemon compiled for kernel 2.4 can not 
work on kernel 2.2.

For each user you can have parameter flag which can be regarded as 
twobit number, which gives us the combinations:
0 - Can only download
1 - Can upload and download
2 - Can modify existing files, download, create directories but not upload
3 - can do everything

At the end of configuration file place three letters: E, O, and F

On my site there is ftp program of about 53 kilobytes. Compressed with 
upx it is about 27 kilobytes. But I might make something smaller.
