Does anyone know of a well established wrapper for iptables?

I've used apf in the past which does exactly what I need, but I've had enough of it's buggyness and it's been acting up since I upgraded to lenny. I'm a step away from just doing the entire ruleset by hand which is fine, but I was wondering if there was some nifty script out there that would make it a bit less work?

Here's what I want:

I would like to be able to share samba stuff to my friend via wireless, while routing my internet traffic through eth0 instead of wifi. But at minimum, I need to have my internet running through my wired connection and not through wireless. Any idea how I can do this or why the network manager won't send internet traffic through eth0?

Wow, I just came to post a similar problem. I have a Ubuntu 8.10 server (with the desktop installed) with 2 network connections: eth0 goes to my internet, and eth1 goes through a wireless bridge to my neighbors wifi. I would like for all normal traffic to go through eth0, but be able to do samba and ssh through his. Problem is, traffic seemed to randomly chose which interface to go through each boot, and when i played with the /etc/network/interfaces (to set a static ip to fix a dhcp problem) all internet traffic ceased (local still worked funnily enough).

How can I force Ubuntu to run traffic through eth0 unless accessed by eth1?

UFW works quite nicely, comes with Ubuntu.

It can increase internet speed for your network by caching DNS records.

Also, you can easily define host names for your entire network, e.g. you will be able browse to http://router/ instead of http://192.168.1.1/ or "ssh myserver" instead of "ssh 192.168.1.100" from every machine in your network.

Combine with a DHCP server for even more control.

I need to become familiar with creating RPMs for a project at work, so I downloaded and installed Fedora because it's the closest thing to Redhat Enterprise, and I really don't want to mess around on my Ubuntu box since I don't know how nicely rpm and debs will play with each others.

Fedora and VMWare are not playing nice with each other.

I install it fine, and turn acpi off in GRUB to get around the common-repeat-rate problem that linux seems to have with VMWare.

I get into Fedora, and oh my god it is slow. I don't know if Fedora just runs a lot more services than Ubuntu or if there is something else going on, if anyone can shed some light or anecdotes please do!

Anyways, I run the updater to bring it up to current. After it finishes, it asks me to reboot.

I reboot, and the Update installed something which is making the distro unusable. It did not install VMWare Tools, but it did install something similar because now my mouse can "escape" from the VMWare window. VMWare does not think VMWare Tools in installed.

This would be a pretty cool, except now every single click -- right or left button -- is being interpreted as a double click.

This is making it pretty much unusable.

So now for the real questions:

1. What do you think Fedora might have installed that made it "VM Aware"?
2. Could this have caused the mouse issue, or did something else in the update lead to this problem?
3. What is the keyboard equivalent of "right click" on an icon after you have it selected?

EDIT : After some more experimenting it's not that every mouse click is interpreted as a double click, it's that both mouse-down and mouse-up register a click, so you get two clicks per mouse press.

You might consider using CentOS instead. It's a recompiled current release of Red Hat Enterprise without Red Hat trademarks (name and graphics). More or less.

That guide was very informative, but I still have one problem. When I delete the static route connecting eth1 to the internet, incoming connections from the internet are also rejected. However, if I add it back in, the computer can't seem to access the internet (local is still fine though). I guess this would have something to do with two routes to the internet, so is there a way of setting a default route to use?

Might as well ask in this thread as well:

If I RDP into a Windows machine using the Terminal Server Client in Ubuntu 8.10, and I set it to connect fullscreen rather than in a window, I can't minimize the RDP session. Someone suggested using the key combination of Ctrl-Alt-Enter, but when I press that, I see the Ubuntu desktop appear but then it forces me back into the RDP session. I'd like to be able to minimize a fullscreen session so I can continue working in Ubuntu but I can't figure out how to get it to work.

This line

code:

up route add -net 192.168.0.0/16 gw "FOOD STAMP CLAN" dev wlan0

tells all connections for IPs in 192.168.* to go through your wireless. Then, you tell your eth0 connection to use

code:

gateway 192.168.1.1

which falls within that range. What are your actual networks' IP ranges?

General Question about Linux : I am working with some very old custom C libraries. What's the cleanest way to integrate these into the system? I really don't want to just dump them into /usr/lib and I'm unsure if there is anything else I need to do to register them.

For location, I would use /usr/local/lib to avoid any conflicts. Not sure about registering, if you want an app to use it, just set the path to include it.

Anyone here use Arch linux? I've gotten tired of Kubuntu having issues all the time so I'm doing a pilot of Arch on my laptop and so far love it.
The initial setup with Arch is a bit longer, but overall it was actually easier to get going and is a hell of a lot faster then Ubuntu was on my laptop.

Only issue I have is the lack of a quality gui wifi manager. I put together a script for connecting to known wpa wireless networks, but for some reason netcfg and wicd don't work and complain about wpa_supplicant. and nm-applet doesn't launch properly for some reason :/

I used to use Arch, but largely on the server end; I did run it as a desktop but that was many moons ago. It's a decent distribution and I loved its package management system -- package creation was the simplest out of all the other ones I've tried, which I really enjoyed.

Granted, that's probably because pacman doesn't have quite the feature set that APT has, but I still felt Arch struck a good middle ground between totally stripped down stuff like Slackware, so-full-featured-it-approaches-byzantine stuff like the Debian family, and the "speed" (since it's all built for i686 instead of i386 like Debian) of source based distros like Gentoo.

I've since come back into the Debian/Ubuntu fold, but still have a lot of respect for Arch.

You could try either wifi-radar or wpa_supplicant with wpa_supplicant_gui I think. I see that wlassistant is also in the tree, but don't know if it's graphical or not.

Look into using LD_LIBRARY_PATH as Ashex hinted above.

Also it should be possible to run NetworkManager under Arch as far as I understand it. Did you have a look at the wiki?

Ah, I'll look into that. It was odd since I would launch nm-applet and nothing would appear in the tray. I tried using Wifi-radar but it didn't work very well, if at all. I've been digging through the wiki the entire weekend getting things setup. I'm a bit disappointed that it doesn't detect my volume keys, but I just use alsactl to set the volume at boot and tpb controls the hardware volume for me.

The script I mentioned uses wpa_supplicant. Basically all I did was add a network to /etc/wpa_supplicant.conf with wpa_passphrase (I think that's the location), and the script just sets the essid, brings up the interface and gets an ip. It's not very efficient since I just have it wait ten seconds before trying to grab an ip.

I've been using Arch for a little more than 2 years now and I've never had any real problems with it. Whenever something has stopped working, it's always been a matter of minutes to fix. All in all, it's a pretty great distro, especially if you like tinkering.

Just log into the web interface, then click "Edit VM Startup/Shutdown Settings" then check the box which allows VMs to start up and shutdown with the server.

When I was setting up my laptop, I spent a good 2-3 hours trying to get the hibernate/suspend keys to work. It would just emit that hibernate/suspend failed sound and it was driving me nuts. I learned how to write handlers for acpi and everything and nothing worked. I finally gave up and rebooted and it magically worked. Because of that, my tagline in #archlinux is "Well, a reboot fixed it"
I've since learned that I should reboot Arch when I'm having an issue, as I have the really bad habit of setting up rc.conf, but forgetting to actually start or load bits I need.

Yea, I've had a few medium-to-OMG mishaps with Gentoo, but a lot less with Arch. However, it's not a fair comparison in my case because I had a bit more experience by the time I found Arch (though I was pretty experienced via Redhat/Debian/Slackware already by the time I was using Gentoo) and I was mostly using Arch on servers where my personal Gentoo use was more desktop oriented.

Arch is also simpler and has less moving parts than Gentoo, given that Gentoo has to manage all the source crap. That's not to say Portage was the best at what it did, either, though -- I liked some parts but others felt pretty overdone.

Certainly, though, if I was given a desert island, a generator, a PC and the choice of an Arch install disk or a Gentoo one, I'd go with Arch hands down.

how are you copying it over? if you're going via terminal, most copy utilities preserve file permissions, so if it sees it as read only, it keeps it that way. Most gui file managers should know it's a disk and reset permissions.

I'm having a problem with Gnome NetworkManager. I am running Gentoo on an iBook G4 with a 2.6.27 kernel. First, I emerged the .65 version (it's unmasked by default in Portage). Nothing worked, although I COULD add it to the default runlevel with rc-update and it would start when the system booted. I wasn't able to find the Network Manager Applet or anything associated with it though.

Next, I tried the SVN .7 version from Gnome's website. Same issues.

Last, I tried the masked .66 version from portage. This one would bring up the Network Manager Configuration Editor, but it did not show any interfaces, and the Applet was nowhere to be found.

Can anyone give me a hand with this? I am able to get on my wireless network with WICD, but it is a piece of poo poo and NetworkManager works much nicer on other computers I have used. I just want it to work on mine.
