[gentoo-user] vsftpd anonymous upload illegal PORT command
I'm trying to upload files from an OS/2 VM in machine A to anononymous upload on another machine on my home LAN. I'm using the allegedly "very simple" ftpd and getting nowhere, and Google isn't helping. To simplify things, I built vsftpd without ssl, and iptables is off on both machines. I don't think it's related to PASV, because the ancient ftp client on the OS/2 VM doesn't understand the "ftp -p" option. My /etc/vsftpd/vsftpd.conf file is... listen=YES local_enable=NO anonymous_enable=YES anon_upload_enable=YES write_enable=YES anon_mkdir_write_enable=YES anon_root=/home/ftp pasv_enable=YES pasv_min_port=3 pasv_max_port=30100 port_enable=YES allow_writeable_chroot=YES I successfully log in as user "anonymous", password "anonymous", execute "bin". When I try uploading a file, I get the 500 PORT error. Anybody have a working config? Or another simpler ftpd server? -- Walter Dnes I don't run "desktop environments"; I run useful applications

I don't have any problems uploading using your config. Who owns /home/ftp? I think by default vsftpd will change the owner to root which would cause problems.

For these kind of jobs I tend to default to netcat (nc) or socat in listening mode, because of its simplicity. However, I am not familiar with OS/2 to know what it comes with. If it has busybox or you can install it there you can use busybox nc and/or busybox ftpd. In answering your question, I think the error you are getting is related to the client not using a passive connection type. Can you enable passive *after* it connects? ftp> passive ls Alternatives are the busybox ftpd service or tftp, both of which are relatively easy to run. -- Regards, Mick signature.asc Description: This is a digitally signed message part.

My server still runs debian, and now my Pi does as well, and all my scripts have to run there, so yes, I have some experience.

I'm trying to transfer a turn-based video game (Galactic Civilizations 2.5) from an OS/2 Warp 3.5 VM to modern, but backwards-compatible ArcaOS5 https://www.arcanoae.com/arcaos/ atftpd seems to be the answer. Both the old OS/2 and the new ArcaOS5 have a tftp client. I've got both of them talking with atftpd on my Gentoo desktop, and it's transferring data as I type. Having said that, I really want to get an ftp server working, as a matter of principle. Please post your vsftpd.conf, and the output of "ls -al /home/ftp" to give me an idea of what I'm doing wrong. -- Walter Dnes I don't run "desktop environments"; I run useful applications
