OpenSSH/OpenSSL is too big... any alternatives?

[Gonzalo Servat]

Hi All

I have a 2MiB DiskOnChip. After installing the kernel, BusyBox, iptables
and a couple of libs from uClibc I only have 400k left of space.
OpenSSH needs to link to OpenSSL and OpenSSL is well over 1MB on it's
own. Is there any alternatives to OpenSSL/OpenSSH that will fit on 400k?

Thanks in advance!

Regards,

Gonzalo.

I got the same problem but I'm running off floppy.

You might look at LSH, a smaller implementation, linked to off
of the uclibc page ( http://www.uclibc.org/uClibc-apps.html )
as being http://www.net.lut.ac.uk/psst/ . No guarantees that it works..
it looks to be SSH v2 protocol, but not updated very recently.
My only connection with it is remembering that it existed on the above
uclibc page :) Have fun,

I did have a look at LSH but I had other problems getting it to work so
I gave up on that one too :)

Now I'm down to using netkit
(ftp.uk.linux.org/pub/linux/Networking/netkit) but getting it to compile
vs uClibc is tricky. I still get errors to do with 'rpc'. I've decided
to just use telnet for the time being (until I can get a bigger DOC) but
even this task is looking doubtful :(

Has anyone had any success compiling netkit (inetd & telnet server)
against uClibc?

Thanks in advance!

Gonzalo

If telnet is enough for you you can use utelnetd

http://www.pengutronix.de/software/utelnetd_en.html

For LSH I'll have a look - be a little bit patient, I'm hopelessly flooded
with other work right now, but it's definitely in the pipeline.

I have:
uClibc
busybox
kernel
dnrd
iptables
vtun
thttpd
utelnetd
pppd+pppoe
udhcp
+ a bunch of other things I can't think of

it makes a 1.41M image, compile everything with uclibc, strip it
properly, and it works out
