grab yourself a compatible USB 3G stick which you can switch to a modem. eg a

help with CF card on Catalyst 6500 with Sup720

[Martin Hotze]

Hi,

can anyone provide a dd-image from a CF card from a Catalyst 6500 with Sup720, 
please.

We have a refurbished 6500 w/ Sup720-3BXL with an old rommon which is not able 
to format a CF card.

(various other methods with formatting FAT16 on Linux etc. did not work; google 
search only pointed to format within a running system, but we do not have such 
a system nearby)

IOS image is already present.

any help appreciated.

RE: Need trusted NTP Sources

[Martin Hotze]

 I'm trying to help a company I work for to pass an audit, and we've
 been told we need trusted NTP sources (RedHat doesn't cut it). Being
 located in Nigeria, Africa, I'm not very knowledgeable about trusted
 sources therein.
 
 Please can anyone help with sources that wouldn't mind letting us sync
 from them?

given that you trust the US-government (well, ...) you might use your own 
stratum 1 server using a Raspberry Pi with GPS.

here is a well done how-to:
http://open.konspyre.org/blog/2012/10/18/raspberry-pi-time-server/

I still need some spare time to get it running, all parts are here, but within 
my office location I have a bad GPS signal reception, so I have to do it at 
home.

So build your own stratum 1 server (maybe a second one with DCF77 or whatever 
you can use for redundancy), off from these servers build 2 or more stratum 2 
timeservers for redistribution to offload your stratum 1 servers.

http://clepsydratime.com/Products/Time-Server-NTS3000 is a cool alternative. 
They are located in Poland, IIRC. And this box sells for less than 2,000 euros 
(this price is 2 years old). And it gives you GPS (USA), Glonass (Russia) and 
DCF77 (land based).

One of the best Timeservers are sold by meinberg.de

just my 2 euro-cents.

Mikrotik Cloud Core Router and BGP real life experiences?

[Martin Hotze]

Hi,

looking at the specs of Mikrotik Cloud Core Routers it seems to be to good to 
be true [1] having so much bang for the bucks. So virtually all smaller ISPs 
would drop their CISCO gear for Mikrotik Routerboards.

We are using a handful of Mikrotik boxes, but on a much lower network level 
(splitting networks; low end router behind ADSL modem, ...). We're happy with 
them.

So I am asking for real life experience and not lab values with Mikrotik Cloud 
Core Routers and BGP. How good can they handle full tables and a bunch of 
peering sessions? How good does the box react when adding filters (during 
attacks)? Reloading the table? etc. etc.

I am looking for _real_ _life_ values compared to a CISCO NPE-G2. Please tell 
me/us from your first hand experience.

Thanks!

greetings, Martin

[1] If something sounds too good to be true, it probably is.

 I am going to be deploying 4 as edge routers in the next few weeks, each

 They will be doing eBGP to upstreams and iBGP/OSPF internally. I went with
 the 16gb RAM models.
 
 However these boxes are basically Linux running on top of tilera CPUs, in
 terms of throughput as long as everything stays on the fastpath they have
 no issues doing wire speed on all ports, however the moment you add a

cloudmark?

[Martin Hotze]

Hi,

rant
it seems that many large providers are using cloudmark services. As far as I 
can tell: their policy is unclear, they can hardly be reached, mails to support 
are bouncing (delayed, then bounce).

yes, the mailserver from one of our customers was blocked and this was OK and 
rightful, because they had a problem (cracked account). After the problem was 
resolved we started removing their IPv4 address from blacklists and almost all 
lists removed the ban immediately.

cloudmark CSI service (reset request form) wants a form to be filled ... and 
they claim that they send out an email ... but it doesn't make its way to my 
inbox (no, no filters ...)

and support can't be reached.

Where are the good old times when the 'net was controlled by techs and not by 
lawyers?

I can't recommend cloudmark.

a WLAN controller will help you detect rogue APs, rescan the area and also

 Along

 B) Force HTTP traffic through a SQUID proxy with SNORT/ClamAV running
 (several other WISPs are doing this with fairly substantial bandwidth
 savings. However I realize that many sites aren't cache friendly.
 Anyone
 know of a good way to check for that? Look at HTTP headers?).  Do the
 bandwidth savings/security checking outweigh the increased support
 calls
 due to broken web sites?
 C) Force DNS to go through my server. I hope to reduce DNS hijacking
 attacks this way.

RE: Re: SORBS on autopilot?

[Martin Hotze]

Oh well,

there's an approach where one splits users into residential and
business, meaning that residential is only downloading, surfing,
... without need of providing any services back to the 'net. At
least with IPv6 one has to rethink this position as there finally is
end-to-end communication and everybody with a limited upload bandwidth
can multicast his content to half of the world (crossing fingers).

inetnum: 82.150.208.0 - 82.150.208.255
netname: AT-HOTZE-NET
descr:   hotze.com GmbH

country: AT

Our position is that we sell internet access at the IP level, a pure
IP pipe - nothing less and nothing more. The customer can have his own
PTR-record with a name matching his domain, he can set up a server or
not. All IPs are static (no need to hassle with DHCP pools, matching
IP to timedate to user for law enforcment). Every customer is served
the same according to his service plan. And we don't make any
decisions wether the customer is residential or business - simple
as that. I won't feel happy with an ISP who wants to make this
decision for me.
