	Description:

	I previously wrote about Kermit for fetching remote files using a
	kermit
	script. I found that it's possible to achieve the same with a single
	kermit
	command, without requiring a script file.

	Given I want to download files from my remote server from the path
	/home/mirror/pub and that I've setup a kermit server on the other
	part
	using inetd:

	File /etc/inetd.conf:

	7878 stream tcp nowait solene /usr/local/bin/kermit-sshsub
	kermit-sshsub

	I can make a ssh tunnel to it to reach it locally on port 7878 to
	download my files.

	kermit -I -j localhost:7878 -C "remote cd /home/mirror/pub","reget
	/recursive .",close,EXIT

	Some flags can be added to make it even faster, like `-v 31 -e 9042`. I
	insist
	on kermit because it's super reliable and there are no security issues
	if
	running behind a firewall and accessed through ssh.

	Fetching files can be stopped at any time, it supports very poor
	connection
	too, it's really reliable. You can also skip files, because sometimes
	you need
	some file first and you don't want to modify your script to fetch a
	specific
	file (this only works if you don't have too many files to get of course
	because
	you can skip them only one by one).
