OLSR mesh GUI $400 {awarded}

pcatiprodotnet

It may be more consistant with other forms to change this entry field to two fields with drop-down on the second like:
"Announce Dynamic Local Route IP: [10.130.1.0] / [24]"
[then translate the /24 into #.#.#.# before inserting into the config]

" Hrm. I'll look into it. "

Thank you for considering it, althought I know what to enter in that field, i'm sure this would be somewhat less confusing for first time users.

It seems that the DHCP server on WAN isn't functioning, even with the correct interface ip/subnet/mask setting. However, when I have LAN set up to do wireless the DHCP functions. I'm using pfsense-pc; I am fairly certain that dhcp on Wan was functioning in beta4, although I don't think you had the code in yet allowing me to (attempt to) modify the subnet.

Try running from a shell:

/usr/local/sbin/dhcpd -user dhcpd -group _dhcp -chroot /var/dhcpd -cf /var/dhcpd/etc/dhcpd.conf $WANINTERFACE

Thanks, I'll give that a try tomorrow at work.

We just finished installing a fair number of pfsense olsr nodes today; they're functioning quite well, DHCP & HNA4 aside. I had no trouble on the laptop when I either hardcoded ip/gateway/netmask(custom narrow) of nearest olsr node OR run olsr for windows thus making the laptop another node on the mesh.

Awesome!!!

Image updated. Please let me know how it works.

pcatiprodotnet

I'll try this today at work. I noticed that the pfsense-pc.img.gz file now contains a pfsense.ISO whereas it used to contain pfsense.IMG; will that work ok on imbedded CF?
Thanks you, -Pete

Not sure but I just rebuilt and copied the image back up.

6. This issue has crept back in.

6. I have noticed that every other I click [Save] on the OLSR configuration page it fails to start OLSR, such as: [save] starts, [save] not-started, [save] starts, [save] not-started, etc…
I would check the logs and there would be No listing for "olsrd[4494]: olsr.org - 0.4.10 successfully started".

Also, one time I tried UnChecking OLSR and Saving but it wouldn't shut down.

10. I set "Announce Dynamic local route" to "10.130.1.0/255.255.255.0" and "Announce self as Dynamic Gateway"=UnChecked. However, it didn't work. It added an empty "Hna4{}" entry to the olsrd.conf file, but the values I entered were Not in oslrd.conf.
It should have added:

IF ("Announce self as Dynamic Gateway"=FALSE) AND ("Announce Dynamic local route"=NOT-EMPTY: user enters "10.130.1.0 255.255.255.0")
THEN the following Hna4{} entry in olsr.conf should look like this :
Hna4
{
10.130.1.0 255.255.255.0
}

I did not get a chance to check the other three possibilities yet in the following Hna4{} config logic:

Basically, here's how the olsr.conf Hna4{} entrys should look based on all possible combinations of settings:

IF ("Announce self as Dynamic Gateway"=TRUE) AND ("Announce Dynamic local route"=EMPTY)
THEN the following Hna4{} entry in olsr.conf should look like this :
Hna4
{
0.0.0.0 0.0.0.0
}

IF ("Announce self as Dynamic Gateway"=TRUE) AND ("Announce Dynamic local route"=NOT-EMPTY: user enters "10.130.1.0 255.255.255.0")
THEN the following Hna4{} entry in olsr.conf should look like this :
Hna4
{
0.0.0.0 0.0.0.0
10.130.1.0 255.255.255.0
}

IF ("Announce self as Dynamic Gateway"=FALSE) AND ("Announce Dynamic local route"=NOT-EMPTY: user enters "10.130.1.0 255.255.255.0")
THEN the following Hna4{} entry in olsr.conf should look like this :
Hna4
{
10.130.1.0 255.255.255.0
}

IF ("Announce self as Dynamic Gateway"=FALSE) AND ("Announce Dynamic local route"=EMPTY)
THEN remove or comment anything existing between the braces in olsrd.conf (not sure if empty Hna4 is legal syntax) :
Hna4
{

}

17. I was unable to get DHCP to work on the Wan wireless interface.

Okay, I'll look at it soon. I have a wedding to attend so I will not have much time for the next day.

I would copy the file /var/etc/olsrd.conf to /root and then add a script to /usr/local/etc/rc.d/ to copy the file back on bootup.

Something like this:

#!/bin/sh
cp /root/olsrd.conf /var/etc/
killall olsrd
olsrd -f /var/etc/olsrd.conf

Since the OLSR GUI isn't finished and I need to get this running, I copied my olsrd.conf configs from Metrix Pyramid (very easy to set up but Metrix isn't stable and crashes most days, at least for me using wrap.2c and atheros).

Other helpful shell commands for custom configs:
make the CF file system writable…
mount -w /
make my new boot shell script executable...
chmod 555 olsr.sh
make olsr it's own process so shell script may exit...
olsrd -f /var/etc/olsrd.conf &

One final hurdle: Metrix Pyramid uses "dnsmasq" to serve dhcp with subset IP ranges and Netmask just like I wanted.
I examined Metrix's dnsmasq.conf file and found the lines for custom dhcp. I noticed that pfSense also uses dnsmasq.
In pfSense, how do I start dnsmasq with my own custom config file?

Thank you,

Start it with

/usr/local/sbin/dnsmasq -l /var/dhcpd/var/db/dhcpd.leases -s domainname.com

Replace /var/dhcpd/var/db/dhcpd.leases with the leases file

pcatiprodotnet

Thanks for the help! I got OLSR and DHCP configured exactly how the should be.
I unchecked the dhcp in pfsense gui to stop dhcpd, and added a boot script for dnsmasq with your parameters plus -C
In dnsmasq.conf I copied from Metrix Pyramid and changed eth0 to sis0 on some lines:
interface=sis0
interface=ath0
dhcp-range=10.130.6.10,10.130.6.254,255.255.255.0,2h# ath0
dhcp-range=10.136.6.10,10.136.6.254,255.255.255.0,2h# sis0
dhcp-option=119,ipro.net

So, now OLSR and DHCP are configured perfectly. I'll post the whole configs here after more testing so they may be integrated into the olsr gui setup.

Thank you,
-Pete

Sounds good. We'll be releasing RC1 soon and as soon as that happens I would like to wrap up the OLSR and get that solid.

pcatiprodotnet

" We'll be releasing RC1 soon… "
It's encouraging to see pfSense under active devoted development. I'm up and running with the
custom configs and startup scripts so this will certainly keep. pfSense is performing extremely well
functioning as olsr nodes. Stable and fast! I am well pleased.

Here are the config files I'm using on every pfSense node in our mesh (although the gateway is
set up slightly different), and they work great; please modify default config settings to match.
My olsr.conf is nearly identical to Freifunk's; they run an olsr mesh in Germany with over 150 nodes.
My dnsmasq.conf is nearly identical to Metrix Pyramid's; dnsmasq completely supersedes dhcpd for me.
Of course my individual settings (eg IP Netmask <node#>comments etc) should be replaced by gui
auto-generated configs. I'll consider this bounty to be finalized when the olsr gui can auto-generate same/
same-in-function configs thus eliminating the need to upload custom .conf files and boot shell scripts.

About my olsr network:
My WAN port IP address block for olsr is: 10.128/13.
Each node is assigned a Class-C within the above range: .1 for itself and .10 to .254 for dhcp to WAN clients not running olsr.
Each node is also assigned a Class-C within the 10.136/15 range for dhcp to LAN clients.
In the following configs, I replace the string "<node#>" with a unique node number between 1 and 254.

/root/olsr.conf

DebugLevel 0
IpVersion 4
ClearScreen yes
Hna4
{
10.130.<node#>.0 255.255.255.0 # this node's WAN clients

#0.0.0.0 0.0.0.0 # Uncomment if I am a gateway.

Comment out the above line if this node is a gateway and thus likely has No LAN clients.

dhcp-option=119,olsr
dhcp-lease-max=254

Issue #17: Solved...
When olsr is enabled, dhcpd process should be stopped, and instead reconfig & restart dnsmasq for dhcp (or, perhaps delete dhcpd from pfSense altogether and use dnsmasq for dhcp full time).

Issue #18: The vast majority of olsr setups will need two "Announce Dynamic local route" gui fields for two IP & Netmask entries. One to announce routes back to local wireless clients, and another to announce routes back to local lan clients. The lan client IP range should be outside of the wan IP range. (I prefer the interfaces not have overlaping IP ranges. And, I tried to get around needing two announcements by turning on bridging, but there is an atheros driver bug in freebsd that causes wan to be Extremely slow when bridged and in ad-hoc mode.)

Issue #19?: Solved...
I am no longer experiencing intermittent problems with ARP announcements from "barely out of range" neighbor node's MACs overwriting olsr preferred routes in the route table. This is likely due to timing alterations in olsr.conf; perhaps one of the altered values determines how often olsr updates the route table. Although I haven't researched the meaning of every config line yet, having tested Freifunk & Metrix and observed how well olsr functions on those systems, I trust their developer's judgement.

Can you do me a favor and test RC1 and let me know what we need to wrap up? Somewhat unsure what bugs are still lingering…. Thanks!!
