Pi Zero W as access point, how to?

Re: Re: Pi Zero W as access point, how to? By: Andy Burns to The Natural Philosopher on Thu Aug 19 2021 09:22 am

Lots of VOIP are harder to do over NAT than FTP is. This is why many mobile VOIP applications need TUN/STUN servers and whatnot. At the very least there are well known solutions for deploying FTP whereas setting certain VOIP services requires you to read three tonnes of additional manuals. Specially if they have some P2P or WebRTC component.

Agreed. The benefit of using SSH transfers is having no more software to install because bog-standard sshd acts as a client to ssh, scp, sftp and (if you happen to have it installed), gftp

Indeed, but ftp is in some ways nicer and IIRC windows clients are more common...

Huh? I'm struggling to think of a protocol causes more grief than FTP, since NAT came along at least.

I meant from the users perspective

FTP demands a two port hole in a firewall anyway, irrespective of NAT.

It wasn't such a big deal to punch two stateful holes in a NAT box.

FTP is kind of obsolete. It belongs to the era of XDMCP and Telnet. FTP uses several TCP ports, and it is not happy over NAT links. The SSH server handles SFTP as well, without extra daemons.

For bad NAT protocols, XDMCP is at least a runner-up, as it has 
IP addresses built into the message bodies.

Still - it is alive in B2B. Yesterday I got a question if our software (at work) supports FTP as a way of sending/receiving transactions (xml in files)

The customer is using SAP (yes they do support other means as well)

Number of times I?ve had an SFTP transfer corrupted by line ending conversion 0. Number of times for FTP, too many to count. Completely horrible protocol from any angle.

On the Mac I had to

open 2020-02-13-raspbian-buster-lite.img touch /Volumes/boot/ssh

in order to be able to slogin into the pi. I haven't tried to set up an ftp server.

Sure, but historically the default was text mode, so in practice corruption was pretty common.

Today I don?t use it at all.

$ ftp whatever -bash: ftp: command not found

Never happened to me. Default has been binary since forever.

Well neither do I mostly. But its not that bad a protocol - I seem to recall it has a few more features than sftp

And its very fast.

True, I have been known to reconfigure firewalls into L2 bridge mode for SIP/RTP mainly to avoid NAT.

That just stays (or worse, gets) disabled.

Yes, but the current imagers for Raspian do already sport a feature (use Ctrl-Alt-X to see it) to have SSH activated right away, so no need to create that ssh file.
