Just "no"; although "both" would probably be more sensible!
The actual code on FreeBSD systems is in /usr/src/lib/libfetch/ftp.c :
int pasv;
...
pasv = CHECK_FLAG('p');
...
if (!pasv)
pasv = ((s = getenv("FTP_PASSIVE_MODE")) != NULL &&
strncasecmp(s, "no", 2) != 0);
There's a similar test in /usr/src/lib/libftpio/ftpio.c.
The nice thing about this environment variable is that you can set it
once in ".profile" or wherever, and then all your FTP downloads work OK
through the firewall :-)
With all best wishes,

Just "no" or whatever is returned by nl_langinfo(NOEXPR)? Or both?

Yes, FreeBSD's "fetch" command uses that, probably via "libftpio". I think the semantics are that "FTP_PASSIVE_MODE=No" (upper or lower case No) turns Passive Mode Off, while any other values turn Passive Mode On (but I can't check the source code while I'm at work!). FreeBSD's Ports use "fetch" to downloading source files; but I think "wget" is nicer. Switching from "fetch" to "wget" is easy: you just change a makefile include :-) Many thanks! - Martin.

wget & FTP_PASSIVE_MODE
Hi, I had a little trouble turning off Passive FTP under FreeBSD 4.8. Fixed OK by creating /usr/local/etc/wgetrc after looking at the source code but here are two small ideas to make things easier: 1. Perhaps wget should obey the setting of environment variable FTP_PASSIVE_MODE (="NO" or "YES")? 2. Perhaps wget should implement: --passive-ftp=on --passive-ftp=off as well as plain "--passive-ftp" (same as "-passive-ftp=on") Many thanks! -- Martin Johnson <[EMAIL PROTECTED]>
