Quick and Dirty Unsecure tunneling on IOS

Submitted by cliff on Mon, 12/03/2018 - 14:38

This is an old post, I posted here a couple of years ago for Arjen Halma. It was the first one I found, so i'm putting it back here for reference.

interface Tunnel0
 description tunnel to other side
 ip address <PTP-IP> <PTP-NETMASK>
 no ip redirects
 no ip unreachables
 no ip proxy-arp
 ip mtu 1480
 ip tcp adjust-mss 1420
 tunnel source Dialer0
 tunnel destination <TUNNELSERVER>
 tunnel mode ipip

Add additional routes for the network on the other sides ;)

Thanks to Saku Ytti, I have a little config snippet that will enable low delay QoS for Cisco 877W (with Advanced IP services) (Your mileage may vary on other Cisco's). It guarantees bandwidth on packets with a max of 200 bytes. This includes interactive SSH, icmp, VOIP and most games.

As promised in my last post I promised to put some configuration online for WIFI configuration on a 877W. But first, I experienced some problems getting VLANs working on the Ethernet ports. It seems you need an Advanced IP Services IOS for this and NOT the default Advanced Security Services IOS. Remember to get 12.4(4)T2 if you want ADSL2+ support!

The relevent WIFI config snippets:

Why Mac OS X sucks

[Legacy Post from my old weblog]

A couple of years ago I bought my first Mac, it was an iBook G3 and at first I was totally in love with the Mac. After the iBook G3, I bought myself a G4 Titanium Powerbook for more performance and it was good. However the last year I started hating Mac OS X more and more.

Bogon filtering using BGP bogon route servers

Currently we are blocking bogon advertisements by using a prefix-list which we are updating manually. The problem with this approach is that whenever an address block is delegated by IANA to a RIR this list has to be updated manually. According to Team Cymru there is an easy fix for this problem and that's peering with there bogon route server.

Cisco / Foundry BGP Config to RPSL

Submitted by cliff on Fri, 17/09/2004 - 08:34

This post has been recoverd from the old site for archival purposes and as it has still been generating some hits.

Last year I built my self an Cisco/Foundry BGP config to RPSL generator to create RPSL for in an routing registry (I primarily use the RIPE database). I did this because there where only tools that could do the other way around, generate a config from your RPSL entries in the routing registry database. As I currently can't find any tool in the wild that can do this I'm hereby opening it to the world. 

Solaris 9 cron

I host a sunfreeware mirror which I cronned to be updates every night at 06:00. However I noticed some weeks ago that this didn't happen automatically. To lame to find a solution for it I just manual updated it sometimes.

But after setting up the crontab for my debian mirror (which is hosted on a other company machine which is running Debian) I decided it would be time to fix the crontab entry on solaris.
