Minimal requirements for NFS server

8 Mb would be tight? What type of memory it needed, 36pins SIMM? Can't you spare a couple of dollars for more RAM?

After freeing memory, it's trying to open the console. So you have that part to deal with.

Before running with nfs, please try walking with basic setup first.

Yup, with 8MB the system will be barely usable.... You really need about 16MB for a usable system....

8MB means no dropbear, probably no telnet, no syslog, just the absolute bare minimum, turn-it-on-and-pray....

I'm not sure about the recent kernel versions, but at that point you have to have /dev populated with the console and tty device names. Since devfs is gone from 2.6, I'm not sure how that works now in embedded systems.... devfs was a good thing for embedded platforms....

You can try running a basic "hello world" type app instead of init to see if init is getting called.

With 8MB, you may not have room for either....

Hello,

As

It is 30 pin SIMM with 8 slots and 1 Mb each. I've seen modules with more but they are too expensive and - more important - very rare. As the mainboard is quite small, I'd like to use it anyway... the system doesn't have a single fan, the only thing producing noise is the hard disk, which I turn off after 15 seconds or so of inactivity.

I hope I can also integrate httpd and telnetd from busybox (I have ~4-5 Mb free after booting with a single shell running). Maybe even a simple interpreter to run scripts via HTTP, but I have to see what's possible.

I think I've given up the try and use my old system with the host libs from /lib, so I can change binaries.

Yes, I thought of that too, but I'm not familiar with C at all and neither with compilers and so on. But this far busybox' init works for me (but not uClibc).

better -

I don't know how much memory a NFS server will take, I haven't got it running yet (simply crashed). But I'll see when I have my sytem up again (a crash killed the relevant files ... I'll never strip my system libs again :( )

I just noticed this - the 40 GB hard disk....

Make sure to give yourself gobs and gobs of swap. I'd go for 100MB or so. What the heck, you have the hard disk storage...

That way, you should be able run whatever you need, albeit slowly... You'll be swapping like crazy, but at least you should be able to run nfs + httpd + dropbear. You may have to wait while the system swaps out one app for another. Just don't hammer it with streaming data while you're trying to bring up that webpage...
