RE: Important New Requirement for IPv4 Requests
by Skywing 24 Apr '09

Of course, sftp and other ssh-based protocols are *still* hamstrung to a maximum of 32k data outstanding due to hardcoded SSH channel window sizes by default for most people, unless you're patching up both your clients and servers. Sadly, this blows ssh out of the water for anything with even modest high-bitrate requirements over moderate-BDP links. - S -----Original Message----- From: Jo Rhett <jrhett(a)netconsonance.com> Sent: Thursday, April 23, 2009 23:27 To: Joe Greco <jgreco(a)ns.sol.net> Cc: bmanning(a)vacation.karoshi.com <bmanning(a)vacation.karoshi.com>; nanog(a)nanog.org <nanog(a)nanog.org> Subject: Re: Important New Requirement for IPv4 Requests On Apr 22, 2009, at 7:42 AM, Joe Greco wrote: > While HTTP remains popular as a way to interact with humans, > especially if > you want to try to do redirects, acknowledge license agreements, > etc., FTP > is the file transfer protocol of choice for basic file transfer Speak for yourself. I haven't used FTP to transfer files in 10 years now. About 7 years ago I turned off FTP support for all of our webhosting clients, and forced them to use SFTP. 3 left, for a net loss of $45/month. And we stopped having to deal with the massive undertaking that supporting FTP properly chrooted and capable of dealing with all parts of the multi-mount web platform required. We've never looked back. Ever once in a while I find someone who's offering a file I want only via FTP, and I chide them and they fix it ;-) -- Jo Rhett Net Consonance : consonant endings by net philanthropy, open source and other randomness

Check out HyperConf http://www.winagents.com/en/products/hyperconf/ It does multi-vendor device backups as well as a scripting function to blow out mass changes to devices. They are also pretty easy to work with to enable new devices if you want them. The licensing is somewhat reasonable. Jon Wolberg Operations Manager PowerVPS / Defender Hosting Defender Technologies Group, LLC. ----- Original Message ----- From: "Joshua Eyres" <joshua.eyres(a)gmail.com> To: nanog(a)nanog.org Sent: Friday, April 24, 2009 4:25:05 AM GMT -05:00 US/Canada Eastern Subject: Config Backup / Inventory Hi, I am looking for a bit of advice around configuration backup / inventory. We currently have a large multi-vendor network which is currently managed through two separate tools (rancid - http://www.shrubbery.net/rancid and ns4 - http://www.noodles.org.uk/ns4.html) Both tools do the job very well, but management have asked that we look for commercial alternatives that have a proper support organisation looking after them. IP Service Activator has been mentioned as something which can fit this role, but I haven't had any experience and I haven't heard a lot of good things about it. We are looking for a tool which is flexible that allows configuration backup to textual form for easy restoration as well as the ability to deploy scripted changes to the network quickly. Do people generally use free tools for network management or are there viable commercial alternatives? Thanks, Josh

Would there be interest in trying to organize a day long mini-nanog with the ietf in March 2010? The regular nanog mtg is scheduled for Feb 22 2010 so this would have to be an extra meeting. and would require all sorts of help and interest from the ietf to put together. Perhaps the NANOG SC can try to figure out if there is sufficient interest in this and what this should consist of? -manish ------- > * From: Iljitsch van Beijnum > * Date: Thu Apr 23 10:37:12 2009 > > * List-archive: <http://mailman.nanog.org/mailman/nanog> > * List-help: <mailto:nanog-request@nanog.org?subject=help> > * List-id: North American Network Operators Group <nanog.nanog.org> > * List-post: <mailto:nanog@nanog.org> > * List-subscribe: ><http://mailman.nanog.org/mailman/listinfo/nanog>,<mailto:nanog-request@nanog.org?subject=subscribe> > * List-unsubscribe: ><http://mailman.nanog.org/mailman/listinfo/nanog>,<mailto:nanog-request@nanog.org?subject=unsubscribe> > >On 23 apr 2009, at 14:17, Adrian Chadd wrote: > > > Methinks its time a large cabal of network operators should represent > at IETF and make their opinions heard as a collective group. > That would be how change is brought about in a participative organisation, > no? :) > >Why don't you start by simpling stating what you want to have happen? > >So far I've seen a number of messages complaining about the IETF (btw, if you like complaining about the IETF, go to >the meetings, there is significant time set aside for that there) but not a single technical request, remark or >observation. > >The IETF works by rough consensus.
