Extending tc and iproute2. Linux routing split access multiple uplinks multiple isps iptables masquerading

Fri, 03 Oct 2008 03:28:33 -0700

http://www.adamsinfo.com/extending-tc-and-iproute2-linux-routing-split-access-multiple-uplinks-multiple-isps-iptables-masquerading/

A followup article to:

http://www.adamsinfo.com/bandwith-limiting-with-linux-tc-and-iproute2/

which focused on bandwidth limiting in a datacenter environment using tc and iproute2.

I’ve taken the same script but tweaked IPs and bandwith values into my office. Previously I was on a 24mbit down 2.5mbit up DSL connection courtesy of www.bethere.co.uk The office is only about 800m from the closest exchange which is quite nice – I generally find I get 18+mbit down and 1.5+mbit up. Not only great bandwidth, but latency is also very small and responsiveness is great, especially as a regular [constant] SSH use. Recently, despite having no business justification whatsoever, I ordered the same again for the same office. This one clocks in at about 19mbit up and 1.7mbit down – even better! Some ISPs support line bonding – I dont believe that many in the UK do, and seeing as at the time of writing, bethere were the only ISP to support anywhere close to 24mbit, I wasn’t going to try and find another.

I did have a similar idea of writing a VPN appliance that could run on a local machine/router and connect to a machine that had greater bandwidth than both lines combined:

[ Local Machine ] – [ Nat Router (VPN Client) ] Over 2 Connections [ Remote Box in NOC (VPN Server) ]

Complicated, difficult and probably never work. Not sure how you’d overcome sequencing issues, delays, congestion, etc, but nevertheless – I didn’t decide to pursue that one.

There’s a great article on lartc that I used as a guideline for creating the split access setup. On my Linux router (deb-etch 2.8.24) I used iproute2 and some shell magic [I’ve blocked out the IPs] – eth0 is my local interface (192.168.100.0/24)

IF1=eth1 IF2=eth2 IP1=XX.XXX.8.214 #IP on conn1 IP2=YY.YYY.123.235 #IP on conn2 P1=XX.XXX.0.1 #Gateway on conn1 P2=YY.YYY.120.1#Gateway on conn2 P1_NET=XX.XXX.0.0 #Network address conn1 P2_NET=YY.YYY.120.0 #Network address conn2

ip route add $P1_NET dev $IF1 src $IP1 table 1 ip route add default via $P1 table 1 ip route add $P2_NET dev $IF2 src $IP2 table 2 ip route add default via $P2 table 2 ip route add $P1_NET dev $IF1 src $IP1 ip route add $P2_NET dev $IF2 src $IP2 ip rule add from $IP1 table 1 ip rule add from $IP2 table 2 ip route add default scope global nexthop via $P1 dev $IF1 weight 1 nexthop via $P2 dev $IF2 weight 1

Job done, now set up iptables for masquerading:

IPTABLES=iptables EXTIF=eth1 EXTIF2=eth2 INTIF=br-lan EXTIP=”XX.XXX.8.214″

$IPTABLES -F $IPTABLES -X $IPTABLES -t nat -F $IPTABLES -t nat -X $IPTABLES -t filter -F $IPTABLES -t filter -X $IPTABLES -t nat -I POSTROUTING -s 192.168.100.0/24 -j MASQUERADE

echo 1 > /proc/sys/net/ipv4/ip_forward

$IPTABLES -A FORWARD -i $INTIF -s 192.168.100.0/24 -j ACCEPT $IPTABLES -A FORWARD -m state –state ESTABLISHED,RELATED -j ACCEPT

Done. We now have net access on both connections, I use:

echo “144000″ > /proc/sys/net/ipv4/route/secret_interval 14400 seconds is 4 hours. This means that we flush dead routes after 4 hours.

The system works as follows. Each time a connection is established outbound, the server will decide which connection to route it out of. The method above should be a rough 50/50 split, with further configuration you are able to change your ratio. The server decides based on congestion and maybe a few other factors. However this isn’t pure multiple connection access that you’d received with a bonded line. One connection can only ever be established over the same route. Say for example I start a download, I will only ever utilize a single connection, and another download from the same IP will also utilize the same connection as this is where the kernel has cached the route to. A 3rd download to a new server will likely be established over the second connection though, as the first is congested and the second is idle. 4 hours after that first download completing, a new decision will be made if the original server is contacted again.

With iptables, using –stats and random, you would probably be able to split 50/50 cleaner as if one connection was established over ISP1, a second connection to the same server could be established over the other connection with no regard for the existing route, however I wouldn’t recommend doing this at iptables level.

As a single user, using the net as a regular home user does, I’m not sure how useful such a setup would be or even if any improvement would be noticed.

It works best in a multi user environment were multiple connections are being opened and closed frequently and simultaneously. It’s also great for torrents such as the debian CD archives. As you’re opening hundreds of connections, the system works perfectly and I’ve peaked at 3.8MB/sec before.

Would be interested in any feedback!

Believe it or not, this guy claims that he can start BBQ charcoals faster with his homemade wire-mesh and hair dryer.

You might want to consider trying this method for your Independence Weekend BBQ.

Whenever I have trouble starting coals for my BBQ I grab a hair dryer, point it at my grill and pull the trigger. One minute later I have red hot coals and I never have to use any lighter fluid to get them started.

Problems with Your PC? Fix Your Registry

Wed, 05 Mar 2008 23:12:57 -0800

Does it feel like an eternity waiting for your PC to start up? Are slow application launches and commands taking forever to execute starting to drive you insane? Do error messages and pop-ups occasionally appear out of nowhere while you work on your computer? If your answer to all of these questions is a Yes, then it is time to fix your computer’s Windows XP registry with some registry scan and repair software.

Registry scan and repair software is built specifically to speed up your computer’s performance and make it execute commands more efficiently. It does this by sifting through each and every entry stored in your computer’s Windows registry, identifying invalid entries, errors and even malicious code and then fixing these errors.

So What is the Windows Registry
Your computer’s Windows registry is that special place in your computer where all the data concerning the settings and configurations of your computer are kept. These settings and configurations, stored as “keys” in your registry, tell your computer what your desktop should look like, how a document in Excel should be formatted, if your files should appear as lists or as thumbnails when you open your Windows Explorer, and thousands of other details pertaining to the way your computer is supposed to operate.

When Problems with the Windows XP Registry Begin
When you first purchased your computer, did you notice how well it performed? With all the power and speed of todays modern machines. That is because the Windows registry contains only the entries to the programs it was initially installed with or was pre-installed with. However, as you began to use the computer—new files are created, and as software packages are installed, uninstalled and reinstalled, all the configuration data in the Windows registry remains stored inside. Eventually, the Windows registry gets bloated with all these invalid entries, and with time, becomes corrupt and fragmented. A Windows registry in such an unhealthy state causes your computer to run very slowly, display random errors and behave erratically. If it is ignored, it can lead to your computer crashing, turning unresponsive or possibly becoming irreperably damaged.

How to Fix Your Registry Problems
To rid your computer’s Windows registry of these problems, you will need a good registry scan and repair application that can fix all these errors, remove invalid and corrupt entries and get your computer running like new again. We suggest solving your registry problems by giving RegCure, our top rated registry repair application, a try by doing a free scan. Or go and read our reviews for a range of registry repair programs and choose the one that suits you best.

Fix a sick PC in 4 easy steps

Wed, 05 Mar 2008 23:12:00 -0800

In a perfect world, you could visit the doctor, discuss your symptoms, and get the cure before you walk out the door. But real life is a different story; getting the right diagnosis can be exasperating and treatments take time.

Your PC has a lot in common with your body- both are complex and vulnerable; disorders are bound to disrupt routine now and then. These PC symptoms may sound familiar:

During boot up, I get error messages.
My PC crashes repeatedly.
Moving from website to website feels like swimming through molasses.

Even when symptoms are obvious like these, treatments aren’t. How do you fix a sick PC that chokes during boot up, is riddled with errors and isn’t up-to-speed online?

Sometimes PC glitches are caused by hardware errors, but more often they’re caused by lack of maintenance. You could call a PC physician to diagnose and treat the symptoms every time-which may be like paying a brain surgeon to get rid of a headache-or you could invest in your own PC first aid kit.

With time and use, the instructions that run your computer can become garbled, separated, even lost. To bring your PC up to speed, you must do some spring-cleaning and basic repair on your computer. Here are four simple tasks that will perk up your PC. While you can accomplish these using separate software programs, PC system utility software is an all-in-one solution that combines the features of several software packages.

Clean Up the Registry
When most people hear the term “broken links” they think of the message the browser displays when a requested webpage is unavailable. But your PC itself is filled with internal links. When you move, delete or add files, links and shortcuts to your system, you eventually create a superhighway maze for your computer to follow each time you access a file. Over time, even your computer can get lost. For example, most people filter and remove spyware and adware programs with spyware removal software, but data related to deleted spyware files (such as links) remains in your registry until you physically clear it out. You can rid your registry of all traces of spyware and adware-and all broken links caused by deleting programs-with windows registry cleaning tools.

Clean Up the Hard Drive
Start by wiping out nuisance files. Unwanted files-spam, duplicate files and remnants of deleted files-pile up and bloat your system. In computers that are not maintained regularly, nuisance files can account for more than 30% of hard drive data. Here’s a short description of common nuisance files, an explanation of how they get stuck on your system and the key to clean them off:

Duplicate Files:
While saving and storing data, you may accidentally duplicate files or sets of files several times. Unless these are backup files, you don’t need them. (Backup files are best stored on a separate device or in a hidden location on your hard drive.

Deleted Files:
Deleted files (including spam) stay on the computer even after you hit Delete; these are stored in the Recycle Bin until you clean it out or until your computer writes over them. You can get rid of deleted files for good with a utility software cleaning tool.

Defragment the Hard Drive
The statement “order creates efficiency” is never truer than when discussing your hard drive. Defragging the hard drive is the key to bringing order to chaos. Data fragmentation happens as your computer takes advantage of small scattered vacancies on your hard drive in order to store data quickly. Your computer must not only remember where it stored each data puzzle piece, but how to put each puzzle back together-this takes time and memory. When you defragment, you reverse this. You instruct the computer to gather, piece together and store each jigsaw puzzle in a single box (or at least store large chunks of puzzles in boxes together on the same closet shelf). This increases your computer’s efficiency when retrieving files. If you’ve never defragged your hard drive you’re missing out on a treat. It’s satisfying to see the visual graphic display showing your memory sorted, regrouped, and neatly stored-freeing up loads of free storage space.

Defragment the Registry
Registry defragging is serious spring-cleaning. This task will clear your registry of gaps, reorganizing all your vital information. A defragged registry conserves memory and speeds load time, including boot up time. But approach all registry tasks with caution. Always backup your registry before making changes in case you make a mistake and must revert. ( For more information on registry defragging, see Registry Software Review. )

Improve the Performance of Windows XP

Wed, 05 Mar 2008 23:11:18 -0800

There are several small things that you should do to tune up your PC performance. First, clean. Get rid of all the spyware hiding on your machine. You might think your computer is uncontaminated because you only visit reputable sites, but if you cruise the Internet, you have spyware. Download a free spyware / adware scan.

After you run a spyware program that deletes active spyware files, you are still left with references to those files in your computer registry. These traces will clog your registry over time, leaving your computer vulnerable to failure. That’s where registry cleaners can help out. Cleaners will eliminate all the leftover traces of spyware and scan your registry for possible problems, saving you from future headaches.

Economize – Space doesn’t last forever
Our computers use space for a variety of things-caching files and images, virtual memory, backups, and of course, storing applications and files. As a general rule, you should never allow your available disk space to fall below five percent of total disk space. Clean house, get a larger drive, or both. This is area where Windows XP registry cleanersa come in handy. You can run file cleaners that will get rid of all the excess junk building up quietly in unseen corners of your computer.

Learn what’s lurking in the background
A good Windows XP registry repair tool also allows you the ability to see what programs automatically start up with Windows XP. Most of the time, you don’t even know these programs are running, but some place a small icon in the bottom right corner of your screen. You can manually right-click on the icons to close them, but this won’t keep them from loading up the next time Windows XP boots up. With a registry repair utility, you can see these programs and choose which ones you want to disable. This will save your processor and memory resources-reserve these for programs you care about.

Don’t delete-uninstall instead
Windows XP not only keeps track of all your programs, it also stores the tools you need to uninstall programs. When you don’t take time to go through the correct process to uninstall old programs, you’ll have stale leftovers rotting in your registry. A good registry cleaner can help you edit the Windows Add/Remove list, completely erasing all those leftover files from deleted applications. This frees up disk space that can be used for more important items.

RegSweep Review | Still the best XP Registry Utility?

Wed, 05 Mar 2008 23:10:36 -0800

Of all the registry software we’ve tested here at Repair-XP.com, RegSweep is by far the fastest at scanning and fixing errors in your Windows XP registry. RegSweep claims to remove all the invalid registry entries from my system in just two minutes flat! But is speed when fixing your windows registry enough to make it the best?

In initial tests RegSweep definitely lives up to it’s speed claim, but doesn’t seem to be quite as effective in terms of detecting errors. Other utilities we tested found more errors, leading us to believe that the software isn’t quite as robust as some other registry repair utilties.

What RegSweep does have going for it, is an option to retrieve updated files from the application’s online database. You can download these updates and ~~- in theory -~~ stay on top of more recent corruptions – whether that’s enough to boost RegSweep to the same level of performance as its direct rivals remains to be seen.

RegSweep simplifies the process of scanning & repairing the registry. All you have to do is load up the program, start the scan, and then follow the prompts to conduct a comprehensive registry/error analysis and repair cycle.

RegSweep isn’t only about fixing errors though. It works to boost your general PC performance by the tried and tested start-up management. Whenever you load your PC, you’ll notice that if you’ve left it to gather plenty of programs, the boot process takes considerably longer. Simple reason for this; the system is having to load more drivers and applications.

By using RegSweep’s in-built start-up manager, you can deselect any applications that aren’t required when Windows loads up. While sounding like a minor option, and it is, you can still manage the start-up processes without RegSweep – but you’ll notice a great difference when you get rid of all those useless programs.

RegSweep will repair your system on a permission-based structure – asking your approval before making any crucial changes, removals or modifications. And, like all industry-standard registry cleaners, RegSweep makes backup of of your system settings (including your registry) before processing any changes.

In a nutshell, it’s one of the easiest solutions to use.

To conclude, RegSweep is not just a registry cleaner, it is a must have tool for any PC user. It can not only scan and repair your registry in record time, it can also help you manage your startup programs so that you are able to increase the overall speed and performance level of your PC. We recommend this tool to both newbie and advanced users alike. Download RegSweep today and feel confident your PC will run fast and smooth.

Registry Repair - The Latest Version of the Popular Too

Wed, 05 Mar 2008 23:09:56 -0800

While it lacks some of the features of the other registry repair applications we’ve reviewed, Migo Registry Repair 5 is a well equipped program to handle your registry cleaning needs. It is geared for the computer novice, so scanning and cleaning your registry is very simple, with a simple one click to start the software scan.

Migo Registry Repair includes several features that make it a handy tool. The startup manager is very useful and its backup utility allows you to roll back any changes the program has made with little difficulty, whenever you clean the Registry, a corresponding Undo file is generated for any changes made which can be used to recreate the entries deleted. You can restore any changes by clicking ‘Restore previous repairs’. For added security,Registry Cleaner uses an ‘ignore list’ containing entries which when encountered upon while scanning are ignored. It also has a system cleanup area that is convenient when cleaning out the junk that your computer stores over time. Another thing that we noticed is that the system cleanup area includes options for cleaning up the Mozilla Firefox browser. This is a feature not included in many of the programs we have seen to this point.

Another nice option is the statistics that it offers you after a scan. You can see what errors the program found, what errors it cleaned and which were ignored. Beyond being interesting, this is helpful in figuring out any weak spots in your computers security.

Registry Repair is one of the safest Registry cleaning tools available in the market today. Its scanning engine is fast, thorough and safe.

RegistryEasy - Registry Cleaning and More

Wed, 05 Mar 2008 23:08:54 -0800

Currently ranking third in our list of top Windows XP registry repair applications, RegistryEasy uses a high-performance detection algorithm that will quickly identify missing and invalid references in your Windows XP registry. A monumental 1,923 errors were detected in our computer system in our initial run of RegistryEasy, after repairing these errors we ran two other PC registry fix software programs and none of the previous errors were detected, which makes us feel extremely good about the effectiveness of this product.

For your convenience and protection, RegistryEasy also provides a backup mechanism for any repaired files so that you can easily recover any changes if required.

Overall RegistryEasy has a very easy and intuitive interface. 3 scanning options are available, clean the registry, Junk File Cleaner and the Evidence Cleaner. You have the option of automatically scanning for all the common errors that might occur on the registry or else you can choose to scan for only one particular type of error. If you have chosen all the scanning options, then it might take a while for it to complete the task, but you can be assured that it is not a long wait either. On completion of the scan a list of errors in the registry that was found is presented. You are given the option of choosing which entry to delete and which entry to retain. The best option is to choose them all. However in order to remove the errors, you need to purchase RegistryEasy. This is common with all other registry fixer programs.

RegistryEasy Evidence Cleaner is an option that can remove your cookies, address bar history and a lot of other stuff and is a rather good addition to the feature set of RegistryEasy. Another important feature is the backup utility always an essential part of any repair process for the Windows XP operating system. If you are a Win XP or a Win 2000 user, you can even set restore points.

One feature that you wont see in other registry cleaners is the ability to manage all your internet explorer objects with RegistryEasy, a feature called Browser HOM Manager, will let you restore Internet Explorer to its default state if your browser gets hijacked by Spyware. This isn’t all, you can scan and fix your windows system errors, register Activex, tweak up your memory, optimize your system and block activex. Most of the other registry fixers don’t even have these utilities. These utilities if applied properly can speedup and improve performance of your system by a significant amount.

RegistryEasy is competitively priced for their full version at $34.99 for a one year license and offers great value for the price. Again, before purchasing the full version it is best to download the free scan to ensure that a complete registry cleaner is needed depending on whether or not legitimate errors are discovered.
