not quite.where to write the VPN server?

I don't understand, both kernel and module are version 2.26.32.27. Am I missing something?

Accel-pptp client is a fully compatible to poptop! It based on poptop! The only differ is a 3-5 times speed boost!!! No other sides. The servers that can connect pptp client 100% can connect accel-pptp! There is no reason to leave this slow pptp client. I have a router with 200 MHz with accel-pptp it normally connecting to my ISP. Its perfom speed near the poptop client on WNDR's 680 MHz! Many people who install accel-pptp clients to they routers are very happy. I havent seen messages that they can not connect with accel-pptp client. I don't need a vpn server in my router, I just want the best and fastest vpn client to connect to my ISP!
It's a super project! By the way it is now included to Linux Kernel since 2.6.37.

It says it's same kernel version you use, why isn't it working?

Otherwise, Thanks much for an excellent build

As said before it is because the kernel you have installed (arokh's image) and the kernel package you want to use are not based on the same configuration.
kmem_cache_alloc is part of the slab cache interface, but since the Jan 8 release arokh switched to the SLOB memory allocator, so thats probably the reason why it fails.

Just posting wireless results between my PC (gigabit) and my laptop Intel 5300 through 3-4 plaster walls and steel frame, distance 10m

2.4ghz Channel 6 with 20mhz 100mW (20dbm) = 8-9MB/s
2.4ghz Channel 6 with 40mhz below 100mW (20dbm) = 9-10MB/s

5ghz Channel 48 with 20mhz 15mW (12dbm) = 4MB/s
5ghz Channel 48 with 20mhz 50mW (17dbm) = 6MB/s
5ghz Channel 48 with 40mhz below 50mW (17dbm) = 9-10MB/s

Distance optimisation set to 20m

Haven't checked any other channels yet.

Looks like SLOB is the cause for the missing symbols indeed, I'll switch back to SLUB which is default for trunk.

Yes. vpn client to connect to my ISP! He is not in the build.

I noticed something strange with this build: when I use Google maps, and particularly Street View, the router seems to 'hang'. Internet traffic gets slower and stuck for a couple of seconds. Also I can't even load the router adminpages. Then it takes some seconds or even longer, and everything will work again! So it seems that the whole router gets stuck. Any ideas?

Does any one have a clue what could be wrong with my 5Ghz config? I get horrible speeds, while 2.4Ghz seems to be fine.
I checked with inSSIDer and the 2.4Ghz band is pretty crowded here (which is why I bought the router in the first place), but on the 5Ghz band I'm the only one.
I tried several configs for radio1, below is the current. I use build r24967.

config 'wifi-device' 'radio1'
        option 'type' 'mac80211'
        option 'macaddr' 'bla:bla:bla'
        option 'hwmode' '11na'
        list 'ht_capab' 'SHORT-GI-40'
        list 'ht_capab' 'TX-STBC'
        list 'ht_capab' 'RX-STBC1'
        list 'ht_capab' 'DSSS_CCK-40'
        option 'disabled' '0'
        option 'channel' '48'
        option 'country' 'NL'
        option 'htmode' 'HT40-'
        option 'noscan' '1'
        option 'distance' '20'

Thanks! I am not for sure about server, but accel-pptp as client is compatible to any server. PPtP is only way to connect to my ISP, but current pptp client is very slow.. That's why I want accel-pptp client and I am not alone! )))  By the way, the factory firmware include ppptp client and it is much more faster (>200Mbit/s). And what about VPN-server in router, it's dosen't matter. It's real special, non-standart feature.

I'm pretty sure there are more people using the PPTP server than there are people using the client to connect to their ISP. Are you sure you aren't using PPPoE? Never heard of ISP's using PPTP clients.

When uploading openwrt-wndr3700-r25018-squashfs-sysupgrade.bin with TFTP i get the following error:

Received bad opcode. Opcode = 18025

I am using a previous image from another date and just wanted to upgrade.

What's up with this error?

sysupgrade is the problem.

use factory with TFTP, sysupgrade with gui

There used to be a adsl-provider in the Netherlands (Planet Internet) that also used pptp for clients.

They would have a router/modem (Alcatel Speedtouch Home) configured at 10.0.0.138 and then on your pc, you'd have to start a pptp-session to 10.0.0.138 to get connected to the internet. Some people modified (through telnet) this router to be Alcatel Speedtouch Pro, which allowed 24/7 connection to the internet, without needing a vpn connection.

But yeah, I think nowadays people would use a pptp-server more often.

Thanks dude.

hi Arokh,

firstly, thank you very much for the great work you do.

I found out why my router was rebooting when I enabled multiwan; the kernel modules needed for that weren't build for the kernel in your image and therefore this resulted in a kernel panic.

The multiwan package depends on the following packages to be installed:
ip, iptables, iptables-utils, iptables-mod-conntrack, iptables-mod-conntrack-extra, iptables-mod-ipopt

AFAIK the mod-conntrack-extra and the iptables-mod-ipopt are not in your configuration and my question is if it would be possible to include those in this build as well?

I made my own build already, but my guess is this would be nice to add in your build as well and the payload is not very high.

kind regards and keep up the good work

Jouk

See the factory firmware... Connection type PPTP. For who they made it? There's not VPN srver in it.
There is one country..... It's name is Russia! Our ISPs most like DHCP+PPTP connection. For Example, BEELINE.
Look http://help.internet.beeline.ru/internet/install/win7/win7_pptp/ ((((
I very like PPPoE, its working fine anyway, but this ISP is not support it! In Russia PPTP is normal practice for ISPs.
If you include pptp-client, that perform like  PPTP in factory firmware Russian users of WNDR3700 will be very happy! ))))
Current pptp client in OpenWRT Backfire & DD-WRT & Gargoyle works very slow. About 16-20 Mbit Down & about 6-12 Mbit Up.
Pings in also not good. I think accel-pptp will work much better. I Would install it to my router myself, but I don't know how. I am not power linux user. ((((
If you need a vpn server you can done it with your PC and port forwarding. But if your ISP require PPTP the router without client is useless for you.

@jouk

The modules should load fine now. No need to include those in the build, few people use them.

New build is out. Thanks to jow for hosting

arokh,

thanks will test it tonight. Would it be possible for you to post a small test with iperf about the wireless stuff? Both on 2,4GHz and 5GHz I do not get any higher speed as 4 MBytes per second. Even though the router and the laptops are saying the link speed is 240 - 300. Just wondering.

kind regards

Jouk

Welcome to the club I will test the new drivers as soon as i am home and report!

Do you get 4MB on 5 or 2.4GHZ? I get about 8MB on 2.4ghz and 5MB on 5GHZ.

@abolition

haven't tested it on 2,4, just on 5. Will give the 2,4 a try tonight.

I did hear though from one of the guys on IRC that he did >90MB on both channels. His build dated from august, so that's kinda strange I guess.

Jouk

Update: this problem occurs also in other builds. Nobody else has this problem? You can test it by going to http://maps.google.com, search for some place and use streetview. Suddenly it stops loading google maps. If you open a new tab you should notice that other sites don't load also. Even logging into the router doesn't work. A few seconds or minuts later, everything works again.
Could it be that it is crashing because of Google Maps creating multiple connections fast? Just a guess. But I really would like to know if you guys have this problem too, so I can rule out OpenWrt or this build. Maybe it is my router or something else...
(Update2: It is a weird problem with Firefox. Everything is ok and is not related to the build or router!)

I just tried google maps including street view and didn't notice any issues.
