RE: [leaf-user] VPN Suggestions?

2004-03-17 Thread Jorn Eriksen
Norman,

I've used PPTP for quite some time.  It's very stable!  The best thing is that
it do not require ANY software on W2K / XP machines...

Have a look here for details:
http://leaf.sourceforge.net/devel/jnilo/bering/latest/packages/pppd/

Best regards

[leaf-user] nameresolution fail with multipath

2004-03-17 Thread Ronny Aasen
hello

I am trying to set up an redundant multipath network
looks something like this

---  ---
| gw1 |--| gw2 | --
DEFGW---| |  | |-| Laptop |
| |--| | --
---  ---

and the routertable shows multipath routes

now eveything works as expected i guess
the laptop can browse the net and things seam ok
the laptop and the gw's all use the same nameserver that sits in the
DEFGW 

but

following command fails on gw2
# nslookup www.vg.no [ip of any nameserver]

and also every command that need nameresolution fail to work


but if i cut one of the multipath links and wait for the ospfd to remove
the multipath routes
like this 

---  ---
| gw1 |--| gw2 | --
DEFGW---| |  | |-| Laptop |
| |--| | --
---  ---

or

---  ---
| gw1 |--| gw2 | --
DEFGW---| |  | |-| Laptop |
| |--| | --
---  ---

then nameresolution function as expected

in all 3 scenarioes i can ping the nameserver ok from all boxes.

hope someone have a clue to give me :)

I can think of 2 causes:

1. You are sync'ing your Bering box to a timeserver in a different

NTP servers usually serve UTC




2. Your entry in /etc/localtime might be incorrect, altho' I don't
   think this is the problem - someone else might elaborate on this.

look at the output of `date`, what timezone does it specify

Ah so, the solution is to load the crc32 module before the 8390

It's not in the FAQ. but it is in the dependencies list.

In my case it changed somewhere around uClibc 2.
When previously I had 8390.o and smc-ultra.o

Hi folks,

This is what I did...and it seems to work O.K. I'm on the West Coast
(Sacramento, CA):

Place this entry in the TZ file: PST+8PDT,M4.1.0/2,M10.5.0/2

Then, end the line with a newline character (hit enter, or it might not work
correctly) if you're using Bering-uClibc.

Place the following entries in Shorewall, and then back up!

ACCEPT fw net udp ntp (if you want to query an external NTP server)
ACCEPT loc fw udp ntp (if you want to query your Bering box time server)

Cheers,

I'd highly suggest OpenVPN - it's easy enough to set up, and well 
supported by the developer (and it also comes with an installer for 
windows clients, which makes setting things up under Windows a piece of 
cake). The only downside is (IMHO) that it only runs on Windows 2000 or 
XP (of course, it runs on every linux plattform I've tried it on). And 
it seems to be a bit more CPU intensive than IPSEC (tried it on a 
head-to-head comparison on a pretty slow box) but unless you're running 
a VPN over a 10MBit link, it should make no difference. Plus OpenVPN is 
_much_ easier to use over NATed connections.

I maintain the lrp for Bering uClibc, but I'm afraid I don't know how 
current the version for Bering is.

Does this card have any major technical advantages over LEAF?  (I know LEAF 
has the advantage of affordability, but from a layman's standpoint, I'm just 
curious what are the advantages such a device has over LEAF.)

the Bering-uClibc distribution since it seems to be more actively

multiple interfaces I'll need. Hopefully, someone will chime in with

From what I've found so far, there is precious little real

HI Calvin,

Bering and Bering uClibc are kissing cousins, so what you find in the 
original Bering docs are relevant to Bering uClibc.  Any differences are 
noted in the uClibc docs.

Check out:
http://leaf.sourceforge.net/doc/guide/binstall.html - Bering Install guide
http://leaf.sourceforge.net/doc/guide/busers.html - Bering Users Guide
http://leaf.sourceforge.net/doc/guide/buc-install.html - Bering-uClibc 
Installation Guide
http://leaf.sourceforge.net/doc/guide/buc-user.html - Bering-uClibc 
User's Guide

As far as your requirements, I think you'll find either to be up to 
snuff, with the exception there is no web based configuration at this 
time.  All CLI baby

Don't forget to backup your disk after making changes, as they will be 
lost upon reboot if you don't.

Good Luck

Tony

Block outbound traffic by IP,subnet,user,port
Block all inbound traffic from untrusted networks except that which is
initiated from inside
Allow all traffic between trusted networks.
Fastest available link should be chosen when redundant paths exist.

Here is a sketch of the network:

DSL = 500 Kbps ADSL Link
RF1 = 100 Mbps RF Wireless direct point-to-point link
RF2 = 1.5 Mbps RF Wireless direct point-to-point link
ISP = 2 Mbps Cable ISP
PLANn = Fast Ethernet Private LANs within buildings at site.

Re: [leaf-user] Is this Hardware more effective than LEAF?

The difference is, its all set up for you and ready to go.

Its alot like any other hardware solution on the market where the OS and 
settings are done all you need to do is configure it match your own 
situation.

Unless of course that board comes with an onboard encryption processor 
other than that it looks like just a standard embedded system without a 
nice looking enclosure and power supply.

Hello, I came across this PCI Firewall card:

Does this card have any major technical advantages over LEAF?  (I know 
LEAF has the advantage of affordability, but from a layman's standpoint, 
I'm just curious what are the advantages such a device has over LEAF.)

RE: [leaf-user] Is this Hardware more effective than LEAF?

2004-03-17 Thread Joey Officer
I have to agree here.  While the idea of using an embedded device that is
intended to do a specific job, and do it well, is really nice, I think its
also intended for a larger environment.

I can see this card being used for a rack of systems that could treat all of
these card as a single device, of sort, and be able to route through the
cards quickly and efficiently.

The specs from the page do not reference what PCI bus it uses, or what
external environment it requires, as it most certainaly will require a host
to accept.

I admit its impressive looking, but I would venture that its rather
expensive and you could probably do more with less, using commodity
hardware, as LEAF does.  For the high end stuff, sure it requires better
hardware, but I think you need to evaluate what it is that you are doing,
versus the hardware you expect to use.

my 2 cents

 Ah so, the solution is to load the crc32 module before the 8390
 module. This is probably a FAQ that I missed, but if not, this would
 be a good thing to add to the installation docs since it's a
 difference from Bering,

 It's not in the FAQ. but it is in the dependencies list.

Anyway we should add it to the Installation Guide...

 In my case it changed somewhere around uClibc 2.

Exactly with the move to newer kernel version 2.4.24
