I'm grateful that openssh-client is available as a package, so I can use its ProxyCommand=... option. Alas, the excellent [proxytunnel] command, which is in the Debian repositories, is not available via opkg. I need proxytunnel in order to fix a problem I'm having with one of the ISPs my remote routers use. (I have to make an ssh reverse tunnel (that the router creates in a cron job) appear to be an https connection to my webserver. Proxytunnel lets me do that on my Debian machines; it's really quite a useful piece of software. But proxytunnel does not appear to be available in OpenWRT.)
Can I interest anyone in creating such a package? Proxytunnel's source code apparently hasn't changed since 2008, it works perfectly, and it's pretty popular.
