Re: Arch mirroring to Microsoft FTP Service

Thanks for the information.  I briefly looked at the ftp code in tla
(libarch/pfs-ftp.c), and it distinguishes between wu-ftp and ftp.  In the
case of wu-ftp, -a is given after the NLST command.  So it seems a
workaround is to treat Microsoft FTP in the same fashion as wu-ftp.

Being unfamiliar with the ftp protocol myself, I am just curious what is the
reason why wu-ftp was treated separately (in the sense that for tla, did
wu-ftp present enough differences from the standard ftp that one set of
commands cannot be used for all ftp commands)?  Maybe older people in the
list may remember the reason...
