wu-ftpd tips

Common mistakes:

Make sure you invoke wu-ftpd with the "-a" flag in /etc/inetd.conf so that your ftpaccess file gets read.
Don't forget to HUP inetd after making the above change.
Your tar and gzip binaries should be in ~ftpuser/bin and should be statically linked. This usually means you have to recompile with the -LSTATIC flag in the Makefile or the -static flag to gcc, and then copy the files to the ~ftpuser/bin directory.
