remote shell by payonel, psh

[payonel 21]

I've developed a remote shell client and rc daemon called psh (payo-sh, like ssh but without the "secure" part)

It's still a work in progress, but at this point should be quite usable for basic operations. You can find it via oppm, just `oppm install psh`

On your hosts that should accept psh connections, run the rc daemon: `rc pshd start`. To have pshd running every boot, make sure to enable it: `rc pshd enable`

From the client, run `psh -l` or `psh --list` to scan/search for available pshd hosts

`psh -f` or `psh --first` to connect to the first host to respond, or `psh -f <address_prefix>` to connect to the first pshd host whose modem address string starts with the address_prefix you specify (this gives a quick short hand mechanism for connecting to remote hosts by just a prefix). No, I don't (yet) have hostname-like support

`psh <full_remote_adddress>` saves you from any broadcast/scan calls, and connects directly to the specified host.

At this time, psh only works stricly with standard io only, it does not intercept nor fake gpu calls.Most programs will assume you can read and write via the gpu, and psh tells the remote shell that a natural tty (and gpu) is available, thus fooling some programs (such as edit).

psh also takes an optional additional argument to run as a command on the remote host (just like ssh does). So `psh -f "" ls` is a fast way to run ls on the remote machine without starting an interactive shell (and close the connection immediately)

In the future I'll be adding `pcp` to the same `psh` oppm package, which will support cp calls (inspired by scp), but for now `psh ... "cat file" > file` works reasonably well. Note though at this time stderr is being communicated to psh as stdout, and thus trying to copy a file in this manner may produce a file with a shell error message (such as if a file doesn't exist). Again, in the future, pcp will be the reliable solution for copying files and folders.
