Shaping on a large scale

2009-01-29 Thread Bruce Grobler

Hi,

Does anyone know of  any Shaping appliances to shape customers based on 
IP, allow for a quota per IP and qos mechanisms like LLQ?,  This is 
should be something that can sit in between two border router's and 
support a small ISP (2 customers), also an opensource solution would 
be great!


Regards,

Bruce

Hi,

Thanks for all the comments!, do you know of any web frontends for these
apps? (don't want to go reinventing the wheel) Something that preferably
uses a mysql backend.

tcng - Traffic Control Next Generation (http://tcng.sourceforge.net/)

Is this true?

This will cause endless entertainment when IANA allocates 1.0.0.0/8

This is a *VERY BAD IDEA* - why not take the hit now rather than
exponentiate the problem and, in so doing, make it nearly impossible to
reverse later?

RE: real hardware router VS linux router

2009-02-19 Thread Bruce Grobler
Not much really, besides your personal preference and the configurability of
the device (will maintaining some semblance of sanity), there are some very
nice custom linux based appliances out there e.g. vyatta routers, which
boast 10 times throughput of Cisco (2800 series) routers, however it all
comes down to what you want to do.

Actually, what is the different hardware router VS linux router?

Have you had experience to compare real router eg: cisco VS linux router?

eg: streaming speed... tcp / udp

Thank you for your information





FW: Ctrl+Shift+6 then X

2009-02-23 Thread Bruce Grobler
Hi Guys,

 

If anyone can tell me how to resolve this issue there's a strong possibility
of a fedex'd beer. 

 

Using Putty or any other ssh/telnet terminal I find that Ctrl+Shift+6 then X
(on a cisco) works only sometimes after beating your keyboard multiple times
with a hammer, has anyone else come across or had a solution to this problem
?

Ye, exact same things happens for me, then after it decides to execute it

Bruce,

I have that problem using any terminal program (I use SecureCRT).. I have to
bang the command like 10-20 times for the device to recognize it. Kind of
wished
CTRL-C or something worked better and actually worked well.

Hi,
Yep does that all the time the worst is on a traceroute where it seems you
need to wait for the end of line to send the ctrl+shift+6.
Workaround on cisco:
Line con 0
 Escape-character 3
Line vty 0 4
 Escape-character 3

Whith this you can just CTRL+C 

Cheers,

RE: switch speed question

2009-02-24 Thread Bruce Grobler
Hi,

It depends on how heavily loaded your switch is expected to be, for instance
two machines using the switch will be able to get a full 1Gbps, however
depending on the backplane (switching fabric), it limits how many ports will
receive full 1Gbps when the switch is congested, e.g. a 2 gig backplane
against a 24 gig.

Regards,

Bruce

Subject: Looking Glass script

I was wondering if somebody knows where to find a decent looking glass
script (PHP or Perl) that is compatible with Cisco 6500 Routers and can
parse the results (bgp, bgp summary, ping, traceroute) so that they can
easily be integrated into good looking HTML tables.

I know there are plenty of good scripts available, but they all generate raw
output. Parsing this data is a lot of coding work and I was hoping that I
did not have to reinvent the wheel.

Thanks,
