Re: WAAS CIFS Optimisation
Do i need to disable default Microsoft SMB signature to get optimal CIFS optimisation? Thanks for any feedback or recommandation Manu IIRC Yes. Also ensure you're on one of the newer versions, older ones ( 4.1.7 maybe ?) have some known issues with Windows sharing. Chris
Re: Possibly a little OT, has spam in theme
Actually it's in Japanese. Nifty is one of the oldest (and at one From here it looks like it's originated by AS2510, which is also Fujistsu. So it is legitimate, even if the unwanted traffic your receiving is not. Owning and using a domain name with 1 character difference from Nifty, its amazing what I used to receive via the catch-all. One of the many reasons I turned it off, ultimately. Chris
RE: Power Analysis/Management Tools
Cacti is a cracking bit of software, but I found this difficult to integrate and customize to what we required. I ended up writing our own, custom pollers, Database backend, web frontend and rrd to generate the graphing. We were quoted something like £50k for something awfully similar..

I'm looking for recommendations on open source packages that people are using for monitoring power utilization of their network/server gear. We're using Cacti currently, pulling the data from APCs via SNMP, and I wanted to check if someone had come across a better method before I reinvented the wheel.
Re: Barracuda Networks is at it again: Any Suggestions as to an Alternative?
We have just as many -- and yes, it's great. The only thing I'd prefer would be Exim over Postfix, but Mailscanner does make things very pleasant to use. +1 for Exim, although development stalled for a while when Philip Hazel retired its now back on track. Also not happy with Barracuda, have a couple of hosts which are blocked by their blocking list and they've refused to tell me why. Chris
Re: Cogent IPv6
Do they issue you a small IPv6 block for your interface, just like they do for IPv4? Is it a separate session? Any things to be aware of before pulling the trigger on it? (Other then them not having connectivity to Hi Nick, They issued a /112 for our interface with a separate BGP session. (In the UK) No real issues with kicking things off (** from the technical side anyway) Thanks Chris
Re: Need Help - Cisco ASA 8.4.1 to Juniper SSG-550 6.2.0r1.0VPN Configuration
Sending 5, 100-byte ICMP Echos to 10.1.4.81, timeout is 2 seconds: IPSEC(crypto_map_check)-3: Looking for crypto map matching 5-tuple: Prot=1, saddr=10.20.1.2, sport=29733, daddr=10.1.4.81, dport=29733 IPSEC(crypto_map_check)-5: Checking crypto map CARIBOU-VPN-1 10: skipping incomplete map. No peer, access-list or transform-set specified. IPSEC(crypto_map_check)-1: Error: No crypto map matched. From my understanding this is caused by the crypto map not being able to establish a tunnel to the Juniper. From that log, the Cisco is missing numerous configuration items: No peer, access-list or transform-set specified. Do you have the above specified in the crypto map within the ASA ? Cheers Chris

haven't been able to find anything that would fulfill the requirements that a smallish ISP might have. The Cumulus guys might be able to provide some pointers ? http://cumulusnetworks.com/ Chris
Re: World Cup Streaming
3. British (English) humor is popular in the US. Very four years, the Three Lions comedy troupe put on a performance that has them rolling in the aisles. With cult performers Rooney, Gerrard, Welbeck, and Hart, hijinks will ensue and fun will be had by all![1] 1. Except the English, who will be bitter and depressed. But they are happiest being bitter and depressed. As a Limey, touche sir, touche. Rooney is the 2960G of football, plenty of potential but you know he won't quite cut it in the enterprise space. With that said, the hair transplant may provide additional buffer space for balls delivered with higher MTU. Chris

Re: Questions on IPv6 deployment
I have a /32 assigned from ARIN (2001:4918::/32) I’m looking for some direction/reading list of how to properly configure IPv6. I’ve read to use a /64 for PtP interfaces and I’ve read use a /128 instead.Assign all loopbacks from the same /64, use a different /64 for each loopback. Ect, ect. I’m trying not to light a religious war but what is the current best practice for IPv6 deployment in a service provider network? PS. I’ll be at NANOG69 in DC next month, 1st NANOG for me after 22 years. ☺ At the start, the advice was to configure individual /64 for loopbacks, however latterly its assign a /64 for loopbacks and configure /128 instead. Stick with a /48 for sites/customers. The best advice is to use nibble boundaries (see: https://www.ripe.net/manage-ips-and-asns/ipv6/ipv6-subnetting-card) hence /52 /56 /60 I also recommend watching this (Tom Coffeen from Infoblox at UKNOF35 which covers this exact subject): https://www.youtube.com/watch?v=lWFcIk4oMMU=youtu.be=PLjzK5ZtLlc90teq9-rGzytIVu-hvsF9hd Its worth a watch and covers the basics HTH Chris
Re: BGP Route Reflector - Route Server, Router, etc
The CSR1000v (IOS-XE),IOS-XRv and vMX are production ready. People are deploying these in production and its increasing in popularity. Mark Tinka gave a good preso at a recent Nanog: https://www.nanog.org/sites/default/files/2_Tinka_21st_Century_iBGP_Route_Reflection.pdf https://www.youtube.com/watch?v=wLEjOj2fyp8=PLO8DR5ZGla8hcpeEDSBNPE5OrZf70iXZg=21 +1 , not used in production but fantastic in a couple of our lab environments Chris
Re: Conference Videos
We record and put on youtube the uknof.org.uk meetings and it still gets bigger every time (around 3x growth since we started streaming). - and we at UKNOF are grateful for Brandon for doing this... :) In terms of UKNOF, we get complaints when we DON'T webcast content or make video's available on YouTube, overall, people coming to meetings is somewhere between coming to see the content and also to network. The YouTube presence helps us to spread the word of the meeting and be as inclusive as possible, on the other hand, we are entirely sponsor funded and try to avoid a charge for attendance. Chris
Re: Conference Videos
Speakers are informed they are going to be recorded. If they have sensitive information, they can choose a track and ask it not be recorded. NANOG has done this in the past, but you should talk to the Program Committee if you are interested in this. We've had this within UKNOF ... sometimes people do not wish to be recorded, mainly due to confidentiality reasons (ie: advance heads up, or personal thoughts delivered to a specific audience). Occasionally we have been asked to remove recordings at a later date due to changing circumstances etc. We explicitly mention the webcast/records on abstract submissions from memory, and also recently introduced shepherding to help presentations be more relevant (both to the speakers to help them in pushing a $clue or message, to our audience to ensure relevance and to us in terms of protection from litigation, etc). This applies to both submitted AND sponsor talks (the latter being incredibly useful and has shown a major increase in sponsor talk relevance and feedback ratings). People will always mention a lack of recording/webcast for this type of content ... but then arguably that is a driver to attend in person. Thanks Chris (UKNOF PC Chair)
