Subject: SEO: detect search engines robots
Posted: 15 Mar 2011 at 7:04am

With power of flightPATH it's possible to detect spiders visits.
There are number of advantages to have that ability.

SEO masters can log such visits and use that info for SEO statistics.

SEO Masters may need to be notified about spiders visits immediately by e-mail.

Another powerful ability is you can provide different page to spider than to end user.
This page may have content optimised for Search Engines.

Following are sample rules:

[jetnexusdaemon-Path-15]
Desc="Log spider requests of popular search engines"
Name="Log Spider"

[jetnexusdaemon-Path-15-Condition-1]
Check="match"
Condition="header"
Match="User-Agent"
Sense="does"
Value="Gogglebot|Slurp|msnbot|ia_archiver"

[jetnexusdaemon-Path-15-Evaluate-4]
Detail="User-Agent"
Source="header"
Variable="$crawler$"

[jetnexusdaemon-Path-15-Function-1]
Action="log"
Target="[$crawler$] $host$$path$?$querystring$"

[jetnexusdaemon-Path-23]
Desc="Give a spider different page"
Name="Cheat Spider"

[jetnexusdaemon-Path-23-Condition-1]
Check="match"
Condition="header"
Match="User-Agent"
Sense="does"
Value="Gogglebot|Slurp|msnbot|ia_archiver"

[jetnexusdaemon-Path-23-Function-1]
Action="rewrite_path"
Target="$path$-seo.html"

Subject: Split media stream and HTML traffic
Posted: 14 Mar 2011 at 9:00am

Sometimes it may be necessary to run media stream content in different enviornment.

For example you may want to use different content servers.

You may also want to split traffic using different Service/Channel:
1. Run media stream over layer4 data type service, which may be faster in some enviornments.
2. Run other HTTP traffic over Accelerate HTTP data type service with compression.

With help of flightPATH it can be done in two ways:
1. Use "Redirect" action - in that case you have to take care that port of media stream channel is available and not firewalled.
2. "Use Server" action to redirect to media stream channel - in that case redirection will be invisible to browser and be done internaly. In heavy load enviornments that way may be slower since media traffic is processed through two channels.

In short all you have to do is:
1. Setup another service or channel to handle media stream.
2. Create necessary flightPATH rule to redirect media traffic to that channel/service.
3. Apply that rule to HTTP service.

Following are sample flightPATH rules:

[jetnexusdaemon-Path-18]
Desc="Redirects requests to Flash Media Streams to appropriate channel"
Name="Redirect Media"

[jetnexusdaemon-Path-18-Condition-1]
Check="end"
Condition="path"
Sense="does"
Value=".flv"

[jetnexusdaemon-Path-18-Function-1]
Action="redirect"
Target="http://$host$:8080/$path$"

[jetnexusdaemon-Path-19]
Desc="Redirects Flash Media Stream traffic to appropriate channel"
Name="Use Media"

[jetnexusdaemon-Path-19-Condition-1]
Check="end"
Condition="path"
Sense="does"
Value=".flv"

[jetnexusdaemon-Path-19-Function-1]
Action="use_server"
Target="$host$:8080"

Hi Fhoek,
 

You might want to disable keep alive connections because of an incompatibility with the application being served or because you want to keep the timeout short.

 
The advantage of a short timeout is the ability to deliver multiple components of a web page quickly while not tying up multiple server processes or threads for too long.
 
I hope this helps. Feel free to ask me if there is something specific you want to do, or not do. Smile
 
Regards
Emily

Hi Msbaker,

Once you get to the CLI you should be able to press enter and then be presented with the login prompt using the default username and password will grant you access to the unit.

Once logged in using the following command you can then get the IP information ifconfig eth0 and then access the GUI on https://X.X.X.X:27376.

Please let me know if this works for you, I can also send you the manual where this is covered in great detail.

Thanks

Just installed the ISO into a VM to test it, I've ended up sat at a command line interface.

Subject: An ADC is not just a LB with more features

jetNEXUS have been developing Application delivery devices for some time now and have continually been trying to convince network managers to separate Application delivery from Packet delivery.

 

Many network engineers seem to struggle with this concept.  The old perception is that ADC’s are like load balancers with an upgrade. They tend to look like switches, containing loads of network sockets with cat 5 hanging out all over the place; basically an evolved switch.

 

Whilst it may be true that the modern Application Delivery Controller does indeed contain much of the functionality of a traditional load balancer, it is however architecturally different.  Most modern Application Delivery Controllers have high speed networking ports that connect to switches.  They are more like proxies than intelligent switches.

 

Application Delivery Controllers are not switches or routers. Design your packet delivery network then build your application delivery network on top of it.

 

Let the network take care of the packet delivery and the ADC take care of the application delivery.

I recognized that the server not apply new ip address.

When restart, it show some errors as below and the ip address restored to 192.168.100.100

Bind failed, will retry....: Socket error # 99
cannot assign requested address

I set the Network Adapter on Bridge mode.

Have any suggestion for me about this error ?

Hi OJG,

Thanks for your quick reply. 

I try again with command: route add -net 0.0.0.0 netmask 0.0.0.0 gw 192.168.2.1

That command not show any problem but I still can't connect to the appliance with https://192.168.2.64:27376/.

When start jnALB, i saw that: httpconfigd Started on http://127.0.0.1:27374

So, I try with http, https and port 27374/27376, but still successful.

Check with ifconfig eth0, it show correct ip 192.168.2.64 255.255.255.0

Check with route, it show

Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.2.0 * 255.255.255.0 U 0 0 0 eth0
default 192.168.2.1 0.0.0.0 UG 0 0 0 eth0

My laptop have ip: 192.168.2.111 (Windows Vista Home Premium x64). I start jnALB on VMWare Workstation 7.0.1 which running on my laptop.

How can i check the connection from my jnALB server ?

If I already started my jnALB server, why the jnDiscovery not show any item in the list ?

Have any wrong in my testing scenario ?

Thanks,
Huy Nguyen

Hi Huy,

Thank you for your comments, if the route command is not able to run can you please try and access the ALB from a computer that is on the same subnet (192.168.2.*). This should forgoe the need for a default gateway until you can access the GUI.

Also, the address to access the ALB GUI should be https://192.168.2.64:27376/, does this address work for you?

with regards to jnDiscover, what O/S are you running?

Best regards,

Oliver Gross
