Re: [SLUG] IPv6
Howard,While in some respect, I share your sentiments (in wanting to get people to think about the move to IPv6) I still think you are way too early. I have been doing network designs and consulting for a the very biggest corporate and government bodies for the last 18 years or so. I have been watching IPv6 as it began its gestation about 10-12 years ago. But guess what - I see almost *no* interest from even the largest of end-user enterprises. Only large software (read Microsoft) and networking companies (read Cisco) have made any sort of effort to promote. While it is built into the core of most current OSes and the higher-end network equipment - that really is about it.
It only will really become meaningful when it becomes the default option from the major ISPs and carriers for the carriage of IP traffic. And even then I would suspect that for the most part, end-users will be able to choose to be shielded from the intricacies of IPv6.
Even in the briefest look around, you will realise how far away real-world adoption really is. Most configuration dialogues and web forms today still try to parse/display an IP address as a dotted quad (eg
1.2.3.4). That is, they ignore the IPv6 format of IP addresses. The other simple matter is that I would wager that if you took 10 experienced (10+ years) network engineers and ask them about IPv6 and what it is about and have they even played with it, 9 of them would probably have told you about the huge new size of the address space, but the need for it has been pretty well removed with private IP address space (
10.x.x.x etc) and NAT, and no they haven't played with it. IMHO it really still is only of real interest to propeller heads (myself included).On the other hand I do believe it will come into play at some stage (because as Vint Cerf once said - every light buld will need an IP address in the future) but my current hunch is that it might be at least 5 years before any credible moves need to be made (by us end users).
I'm happy to be contradicted.Regards, MartinOn 10/5/06, Howard Lowndes [EMAIL PROTECTED]

Re: [SLUG] Wireless ISP Recommendation

Regards Jamshid By wireless internet, do you mean roaming wireless. Similar to Unwired? They're modem (well the one I have) just has a straight ethernet plug, no other setup. Works fine with everything. Except I don't recommend unwired or any of their resellers as they're plans are poor, service is pretty crap, download speed drops to 32/32 when past the limit (which was changed a month ago WITHOUT informing customers) and they throttle certain types of traffic. For example, trying to update my Debian sid box resulted in them completely blocking any FTP to ftp.debian.org for a couple of hours. Maybe look into iBurst? Although they may be just as bad.

Re: [SLUG] IPv6
Hi Martin, While in some respect, I share your sentiments (in wanting to get people to think about the move to IPv6) I still think you are way too early. I have been doing network designs and consulting for a the very biggest corporate and government bodies for the last 18 years or so. I have been watching IPv6 as it began its gestation about 10-12 years ago. But guess what - I see almost *no* interest from even the largest of end-user enterprises. Only large software (read Microsoft) and networking companies (read Cisco) have made any sort of effort to promote. While it is built into the core of most current OSes and the higher-end network equipment - that really is about it. I did a quick Google in an attempt to find the benefits that IPv6 has over IPv4. There does not seem to be a killer app for IPv6. The thing that impressed me is the ability for a IPv6 node to be mobile and maybe with the prevalence of wireless ISPs IPv6 will become a reality. I also read that IPv6 is more efficient to route, so what does that mean in percentage terms? Do you think it will be a good idea to start IPv6 networks from the ground up, instead of starting with IPv4 and upgrading to IPv6? It only will really become meaningful when it becomes the default option from the major ISPs and carriers for the carriage of IP traffic. And even then I would suspect that for the most part, end-users will be able to choose to be shielded from the intricacies of IPv6. End-users for the most part use domain names so this wouldn't change. Even in the briefest look around, you will realise how far away real-world adoption really is. Most configuration dialogues and web forms today still try to parse/display an IP address as a dotted quad (eg 1.2.3.4). That is, they ignore the IPv6 format of IP addresses.

IMHO it really still is only of real interest to propeller heads (myself included). From what I read, IPv6 has been rethought and re-engineered so that it just works a lot better. On the other hand I do believe it will come into play at some stage (because as Vint Cerf once said - every light buld will need an IP address in the future) but my current hunch is that it might be at least 5 years before any credible moves need to be made (by us end users). Maybe ubiquitous wireless mesh networks might do the trick... I'm happy to be contradicted. I'm not really contradicting, just wanted some peoples thoughts on the matter, because I have been ignorant.

[SLUG] Script headaches
I am having some issues with scripting that I am sure some script wizard will solve in 2 seconds, but I just have hit the wall with my patience. At my work we have huge mail traffic, and a huge portion of that is spam, which we have successfully killed off, mostly with the use of blacklists, which we collect a lot of via rsync and deliver to rbldnsd. All of this aside, the files arrive in gzip format. Now, so that rsync only gets what it needs to I want top preserve the compressed version, but unlike bunzip there is no -k option, and bunzip doesn't do gzip files. So, then, I try and use a for loop in a script with gzcat, but then I just can't get the swing of getting the truncated string outputted from expr and finally got the irrits with the whole process, because there's surely a better way. Here's by very broken script: #!/bin/sh RBLFILES=/var/rbldnsd Echo Process rbldnsd domain files rsync'd in gzip format n=0 cd $RBLFILES for i in * do n=`expr $n + 1` echo Processing RBL domain file: #$n [$i] truncname='expr $i : '(..)' /usr/bin/gzcat $i $truncname Done And I tried: #!/bin/sh RBLFILES=/var/rbldnsd n=0 cd $RBLFILES for i in * do n=`expr $n + 1` echo Processing spam [$i] #$n expr $i : '(..)' | $truncname /usr/bin/gzcat $i $truncname done Any help humbly and gratefully accepted. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
