where would PostMountSrv reside? it isn't a syscall.

it is not difficult to do by hand; this version of go9p's timefs example posts itself to /srv (plus some code to fake a few unix'isms on Plan 9). there is no authentication; permissions on the /srv file determine if a user can mount it:

https://github.com/9nut/plan9/tree/master/go9p_timefs

a package that wraps the factotum-to-app rpc protocol (like libauth) would be useful.

Thanks, I think I'll have to do a bit more reading to understand this. I'll check out ramfs and 9pcon.

Is this simpler if written in C using "postmountsrv" with a mount point? I'm assuming that it doesn't require a tcp port and explicit authentication handling using libauth on both ends.

If so, then I wonder why postmountsrv is not exposed via the Go 9P libraries?

short version: you need libauth in Go (or start the go9p client/server by C programs that do the auth).

9P facilitates authentication (but doesn't define or dictate the method). intro(5), auth(2) and factotum(4) will be helpful. basically Tauth is used to request a fid to negotiate authentication (a.k.a. afid). Tread's/Twrite's to afid are proxy-delivered to the factotums (authentication agents) of the sever and of the client by each side. once server's factotum is convinced, the server is granted the system privilege to change its process id to the authenticated user. the client attaches (Tattach) to the server's namespace by providing the afid in addition to other parameters. tools like 'ramfs -D' and aux/9pcon are very handy for watching 9P in action.

i'm copying to 9fans; it might be a better place to continue.

I see that go9p supports authentication. Assuming the client and server are both plan9 (even the same system), how does one hook up the OS's authentication?
