You've confirmed what I was looking at. I saw some config variables, but they didn't appear to
work. I can almost do what I need via lynx. I'm thinking it might be easier to set up something
that just lets me proxy surf on 80 and 443. so the request comes from the allowed IP address.

Oh. I gotcha. I didn't realize you were talking about an ssh proxy.
I thought you were talking about SSH's VPN mode (SSH-BASED VIRTUAL
PRIVATE NETWORKS is the heading for the VPN mode in ssh(1)).

Indeed if you were only concerned about http/s traffic, that would be
the way to go.

there is a "sendmail" option so you can tell mailx what sendmail to run. YMMV.

There isn't because it simply starts a pipe to sendmail and feeds the
message into it.

Is there any way to tell mailx to ignore an email server configured in sendmail.cf or in /etc/hosts and just do a DNS lookup? I don't see anything in any docs for a flag or anything to do that.

I was able to configure openvpn to forward all network traffic including
DNS but I felt the performance hit. In fact my only experience with
openvpn was using it in this way so it would explain while I'm a little
biased against it. I would still recommend ssh tunneling in 95% of the
cases. Only when an application won't work through a ssh proxy should

Have you ever gotten this to work? There is one situation where I need to access a web-page from the
server IP address. Never could get openVPN to quite do that. (I never could get it to get it to
use the servers DNS either.) I have gotten openvpn to work with IMAP quite nicely.
I don't think WRT54 supports the 'n' mode...

Actually my original question was more for security than multiple access.

Dario,

I didn't get the idea from the original question that the concern was
line security--more along the lines of being able to drop multiple
systems on the ethernet of the wireless router and having a black-box

Not to derail the topic here, but what is the basis for the comments
on openvpn's performance? I've worked with OpenVPN and OpenSSH for
years. There have been times where I've used OpenSSH's tunnel mode
because it's there and I need a temporary solution. Unless something
has changed in the last version or two of OpenSSH, I generally found

MySQL report generator?

Anyone have a MySQL report generator they like? Preferably OSS and written
in PHP - I'd like to adapt it for a current project.

Deviation and deviance (appropriate to the blood pressure, components,
timing and other metadata) are things you'd probably just tell TeX to
calculate and graph, or make the medical XML data (or throw to RDF)
and pick something to render SVG, TeX, PDF chewables, and whatever
suits.

Re: [KULUA] Re: logging- graphing software

That's what it's used for in the networking world. You can freely choose
what you want those intervals to be and it gives you a compact way to store
data in a predetermined file size. I could see as a good fit for something
like medical equipment. You get to determine when/if there is data rollup

RRD is mainly for long term measurements that need reduced resolution
the further back you go. For example, today's data is stored at a
sample rate of 5 minutes, but the weekly graph is every 30 minutes (or
something like this) and the monthly at 1 hour and so on. As samples
fall off of one queue for another, the values are averaged into a

You might look into rrd files and rrd-tool. It's what's behind most
the network/server stat graphing packages.
