Well, the UML can connect to any port in the host
And also to anywhere in the Internet pretending to be
your host.
I think most programs in your host won't be able to
tell if a connection comes from the host of from the UML

This won't work. This is ICMP
You can browse a web page, telnet to a given port, etc.

It would be nice to debug the sshd issue, and I hope you
do it. While you do that, you could get networking using slirp[1],

Thus far, I have tried the following things:
1. The Debian-provided version of UML, which hangs on starting sshd
(and in some other cases, that's just an easy one to replicate).
2. Various versions I've found on the 'net, such as
linux-2.4.27-um24271-netfilter2004 and
linux-2.6.11-rc3-bk2-u
In my quest to get a working UML, I've tried compiling a version of
2.6.13.2 with SKAS. I get:
VFS: Mounted root (ext3 filesystem) readonly.
cannot set up thread-local storage: cannot set up LDT for thread-local storage

Whups, wrong script. Well, it works with 2.6.13.2-bs2 too:
Checking for /proc/mm...found
Checking for the skas3 patch in the host...found
UML running in SKAS3 mode
Checking PROT_EXEC mmap in /tmp...OK
Linux version 2.6.13.2-bs2 ([EMAIL PROTECTED]) (gcc version
3.3.5-20050130 (Gentoo 3.3.5.200501
On the system I was having the sshd hang on, I'm trying again with
http://www.stearns.org/uml/linux-2.4.27-um24271-netfilter2004.bz2
instead of what Debian unstable has. With the "linux" from UML from
Debian unstable, networking works (until it hangs), but with this
version I get:
mooix:~# if
Where is the best place to get a 2.4.x UML? I just need the "linux"
command itself. Were is it most up-to-date?
