As others have posted, "SOHO" means "Small Office/Home Office." You may
be referring to a specific brand of product, though, SOHOware. This
company makes low-cost networking products like Ethernet cards. Some
other companies sometimes put "SOHO" in the model number of a product,
presumably to indicate the target market. There's little or no difference
between what will work properly on a small (SOHO) network and what will
work on a much bigger network. For some products, though, bigger networks
may demand faster or higher-quality products (such as switches rather than
hubs, or Ethernet cards that impose the smallest possible CPU overhead).

What's your definition of a small system?
I've read several articles in networking journals (usually as a part of
explaining why GigE cards in a PC are pointless) that a PC host can't do
much better than 30Mbps. Testing showed most 100M cards only providing
20-30Mbps, and GigE cards providing 35Mbps. While the card may be able
to do faster, the software and I/O architecture can't keep it
saturated.
I've seen other hardware platforms saturate 100M links. (I've seen Sun
boxes come close to saturating OC-12 622Mbps links, but that's during a
throughput test, not with an application generating real data.) But I
wouldn't begin to consider these systems "small".

I'm not using this specific product, but I am using a 5-port Linksys
10/100 hub and a Linksys 10/100 NIC in one of my computers. They work
fine, though the vast majority of the Linksys 10/100 NICs on store shelves
today use PNIC Tulip clone chips rather than "genuine" DEC Tulip chips.
The result is that you'll probably have to recompile your kernel (or at
least your Tulip driver) to get the board to work with Linux.
One other caveat: Some kits of the type you describe come with 10/100 NICs
but only 10Mbps hubs, or some other crippling feature. Be sure that ALL
the components are capable of the 100Mbps speed.

You have NT4 SP3 or later, don't you? :-)
The message is misleading. Samba is asking for plaintext password, and
NT4 is configured by default to refuse to connect in this case. Two
options:
1. Enable plaintext passowrds in NT (there is a registry import supplied
with Samba)
2. Configure Samba to do encryption

Have you tried getting the rpm or source and building and installing
dhclient or dhcpcd? And make sure that you are not trying to run the
server which will not give you a valid IP. It seems to me that this is
what you are doing. Try just typing dhclient or dhcpcd instead of simply
dhcp. Good luck.

Just make sure that it is using the right driver. dhcp will fail if
eth0 isn't working, and not usually for any other reason.

Alright, I am intrigued but confused. If you are masquerading, then
the IP's for the unregistered machines would be private and not router
adressable (192.168, or 10.0.0 or whatever the other is) and definately
not on the subnet that your masq machine is. Since those are private,
you can't get to them in any fashion other than to telnet into your masq
box and from there reach out to the unregisterd machines. This is by
design.

I think what you are trying to do is take your laptop anywhere on
campus and use it as an unregistered machine behind your masq machine.
Am I right? If so, you can't do this. And does the route you set work if
it isn't the default? I know it shouldn't, but I am curious. Anyway, the
laptop IP would be not addressable by most routers and therefore the
traffic won't go because it can't be routed once outside your box. Try
thinking PPTP and tunneling. This might work for you. But once again, I
don't think so unless you use a modem as it requires a valid IP on both
ends to tunnel. Masquerading is great, but it isn't a miracle worker.
Things like this aren't possible due to technical constraints and then
if they were, the security would be a nightmare. Anyone could attach to
a box and then do whatever they want anonymously. I won't go as far as
to say what you want to do is impossible, but I will say that in my
opinion it is impossible. Sorry.

Good luck on this one, and if you do solve the problem, then post the
answer here. Many might be able to use it, and I am curious.

Say, something to browse files. Samba doesn't seem to work over the

The other problem is that the other end may have their SMTP
daemons/servers set to perform a reverse IP lookup. If your IP address
doesn't resolve out to the domain name in your e-mail headers (it won't in
your case from what I'm seeing) then the server will reject the message.

Hi! We don't use runsocks on Unix because we don't have any Internet
apps on Unix that require SOCKSification. Netscape is basically the
only Internet app we use on Unix and it speaks the SOCKS4 protocol
natively, so we got lucky.
Here is the URL for the manual page on runsocks:
http://www.socks.nec.com/man/runsocks.1.html
Basically, you need to make sure runsocks knows which SOCKS server to
use, whether to use SOCKS4 (w/o userid/password authentication) or
SOCKS5 (w/ userid/password authentication) and the userid/password info
to connect to the SOCKS5 server (if that is what you use). You should
be able to get the SOCKS4 vs SOCKS5 stuff from your Windows "AutoSock"
program configuration.
The man pages should have the rest of the info. If you still need
runsocks specific help, you can post a messages to a SOCKS mailing list
and possibly get help from one of the SOCKS gurus. Here is the mailing
list URL: http://www.socks.nec.com/socksinfo.html
Good luck!
Peace....
Tom

Get the latest pump.rpm
Im using pump-0.7.0-1mdk.rpm. The change log on it notes fixes that
were done for RoadRunner and @home.
Ive installed this new pump RPM on my machine (RoadRunner) and a
friends machine (@home in N. KY) and it works beautifully.
Before I had to use dhcpcd instead of pump in the /sbin/ifup file.
And of course with his @home I needed to do the "-i HOSTNAME" thing.
also.
With the new pump everything worked fine with a stock /sbin/ifup call
to pump (the @home system needed the "-i HOSTNAME" entry).

Netscrape for Linux never got quite the programmer support that
Windows/Mac versions did. By virtue, it is chock full of bugs. I can
make it crash whenever I want seemingly. Here are some things I have
noticed.
1. 4.51 is the most stable! If you are having problems, I suggest this
one. 4.6 and up are bugfix releases and have implemented all sorts of
new bugs.
2. Turn off Java if you can. This will save some headaches if you don't
use it.
3. Don't bother with BIND or a workaround for the helper. This probably
isn't the source of most crashes. I would say, in fact, that most
crashses are due to resource usage (opening 20 windows) or Java usage
(bad applets will kill netscrape, and good ones can still hobble it).
The networking code is holdover from 3.x and is pretty stable. And motif
is probably not to blame either. Maybe for some of the more exotic bugs,
but I wouldn't guess it is a major reason for crashes.
My observations/opinions, and should be treated as such. Anyway, I am
using 4.6 and have learned to live with the occasional restart of
netscrape. I don't lose anything, resources are freed fairly well by
Linux, and when it does go down, I don't have to reboot as I would if it
crashed in MS.
And Mozilla is only a few months off (by January I hope) and should be
one of the more stable products out there for Linux judging by what I
see on bugzilla. If I had more time, I might help also. Too busy writing
my own stuff though in the case you wanted to know.

OK. What I'd do would be to install PHP (http://www.php.net). It's a
server-side scripting language, in the same fashion as ASP is. It can be
compiled with Apache, or used as a CGI. If you don't mind taking the
time, then learn it. It's nice. Of particular interest to you, it has
functions for loads of different databases, including ODBC which you could
use to talk to Access.
However, you can stick with your ASP. Look at
http://www.nodeworks.com/asp/. It allows you to serve ASP pages on an
Apache server with mod_perl (http://perl.apache.org/) installed. I
haven't used it myself, although I'd be interested to hear from anyone
that has, as a friend of mine wanted me to host some ASP pages (he doesn't
want to learn PHP now he knows ASP) on my (Linux) machine.
There's also a program out there that will convert ASP scripts to PHP
ones. I don't have a URL for it I'm afraid. A look at the PHP homepage
might reveal something.
