Thank you, anyway ! \bye Hi again, I suppose it is your firewall blocking the inbound ftp connection which the ftp server tries to establish after the ls command. In active mode the server initiates a new connection to your machine while in passive mode the server opens a new port, tells your machine the portnumber and your machine initiates the new connection. So rules like eg. iptables -A INPUT -p tcp -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -A INPUT -p tcp -j DROP which allow connections established from your machine but block new incoming connections, allow passive ftp but not active.

Re: Problem with ftp access
Nicholas, I have an annoying problem with my new LFS box (LFS SVN post 6.3, BLFS SVN) : Everything is working quite OK...except ftp. When I want to connect to an ftp server, everything goes OK until I want to dir a directory : ftp ls 200 PORT command successful. Consider using PASV. 425 Failed to establish connection. I've had this exact same problem. Unfortunately, it was a while ago and I can't remember what the cure (or the exact cause was). Fortunately, I do remember it had something to do with the fact that I had two or more NICs in that machine. In my case I couldn't get a connection to go under any circumstances, period (eg., even if I set ftp up for PASV mode). I'll keep looking in my archives and see if I can't find something more specific. In the meantime, Dan's suggestion r.e. strace is a good one; you might also get some use out of tcpdump (http://packetstormsecurity.org/sniffers/tcpdump/ - read the docs; I'm fairly certain you'll need libpcap, too). Two quick questions - they're pretty obvious, but you know how that goes - you're not blocking port 21 or port 22, right? And, if you have openssh installed, have you tried sftp? Hope that helps - Larry -- http://linuxfromscratch.org/mailman/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
Problem with ftp access
Hi. I have an annoying problem with my new LFS box (LFS SVN post 6.3, BLFS SVN) : Everything is working quite OK...except ftp. When I want to connect to an ftp server, everything goes OK until I want to dir a directory : ftp ls 200 PORT command successful. Consider using PASV. 425 Failed to establish connection. Same problem with the ftp program from cpan, I guess, for I can only retreive packages with wget or lynx. With Firefox and Konqueror, ftp is fine. Ncftp works fine, so I think it's a specific problem from the core ftp program installed in LFS. How can I trace this problem to it's origin ? Thanks for any help. \bye -- Nicolas FRANCOIS http://nicolas.francois.free.fr A TRUE Klingon programmer does NOT comment his code -- http://linuxfromscratch.org/mailman/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page

I don't have any ideas, but I would try strace. http://sourceforge.net/projects/strace/ strace -f -o ftp.log ftp Then just do what you normally do. There will be a lot of output in ftp.log, hopefully something will point you in the right direction. -- Dan -- http://linuxfromscratch.org/mailman/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
