Hello, yes i feel alot better now, i have 3 confirm questions;

1 - can u confirm that the filename and checksum are same as urs?
dd-wrt-21676-Asus_RT-AC66U.trx

md5= E7B5A47764160D32A05D7B57FA45AF8C (all was checked unzipped)
sha1= 74CDD09B0780FF95E059A9562DAC3C765981445F

2 - is the SSH on port 22 working on the dd-wrt version 21676 ?

3 - is the firewall log management working on the dd-wrt version 21676? the accept/drop/reject logging?

1. Yes - verified.
2. Yes - verified.
3. Not sure - don't use the firewall (using in wireless bridge mode)...

You should be fine....

i found out that this command from Brainslayer makes a cfe backup in bin format; cat /dev/mtdblock0 > /tmp/cfebackup.bin but i dont know how to copy it to my usbstick sda1? ive tried cp cfebackup.bin /tmp/mnt/sda1 and i tried cp cfebackup.bin /tmp/mnt/sda_part1

Any ideas?Btw thanks for all the help so far most of it was very helpfull thnx!

1. Yes - verified.
2. Yes - verified.

What happens when you do the cp? Do you get an error or are you just not seeing it on the USB stick?

No problem, by the way, glad to help where I can.

Btw, does the dd-wrt version 21676 the one u use now have a working 5Ghz WIFI?

Anyway the only differents between the two ac66u i have i saw is the stock firmware version, the one am testing in now is this version 3.0.0.4.260 and the other one is this 3.0.0.4.266 version but i dont think that is the problem.

could anyone who not use bridgemode please check this Firewall Log Management accept/drop/reject ip/port etc for me 3. Not sure - don't use the firewall (using in wireless bridge mode)...if u use the dd-wrt version 21676 that is.

I allready mailed the developers of asus-wrt if they could make SSH in the next firmware version, i not fully remember if i asked for a CFE backup posibility but i will ask them to add it somehow.
Also mailed alot other ideas to them but thats offtopic.

U guys think that if they would enable SSH in asus-wrt that than we could use WinSCP or SFTP to download the CFE backup binary file to our PC? would that be usefull or?

It looks like the command above worked (the "cp cfebackup.bin /tmp/mnt/sda_part1" command). If the command is successful, it will not print any result.

To make sure the file is there, type this:

Code:

ls -l /tmp/mnt/sda_part1/cfebackup.bin


and it should show the file.

Really though, you'll be fine... Smile

You can always revert back to stock if you don't like DD-WRT... I've done it already - it works.

@gekko2013 - so, did you ever "pull the trigger" and flash DD-WRT on your AC66U?

Just curious how you made out...

Thanks.

Well not yet, i want to be sure i have the bin version also, i also was becoming a bit lightheaded with all the info and i needed a good knight sleep but today i will try to get the cfebackup.bin file again and than .i will flash one of the router with the dd-wrt firmware
I also still need to know if 5Ghz wifi works? and i also need the log managent to work in v21676.

Yes, both 5Ghz and log management work fine in 21676. 5Ghz is what I use most (wireless bridge between two AC-RT66U's via 5Ghz wireless-AC). I've had no stability issues whatsoever.

Although, to be honest, I'm really not using a lot of the DD-WRT features (mainly use it for the wireless bridge functionality), so I can't guarantee *everything* works.

For the "cp" stuff, just type in the filenames exactly as they appear in "ls -l" and I don't see how it could fail.

Code:

cp /tmp/cfebackup.bin /tmp/mnt/sda_part1


Like I said, when the cp command works, it won't output anything at all. Then to verify that the file was copied:

Code:

ls -l /tmp/mnt/sda_part1/cfebackup.bin


Hope that helps.

Hello, yes i will try it out thanks

And this is the crap i did to see if it would work, not understanding what i did but i have the backup of the second router now to, wich means the .260 or 266 firmware asus-wrt version didnt matter, but heres the outcome of it and i will explain what i did first;

i did some DIR switching to /tmp and than i did ls- l to see if the cfebackup was stil their, it was gone wth? well so i used the command from brainslayer to make the backup again in BIN format wich worked;

Well adventually i had to switch the usb stick to the other usb port, dont as kwhy i dunno but that in combination with changing this;

cp /tmp/cfebackup.bin /tmp/mnt/sda_part1

to
cp /tmp/cfebackup.bin /tmp/mnt/sda1 this worked i guess thats a asus-wrt thingy.and now i have to test the ls -l thing again to see if the checking commandline works. brb...

and so i changed also the command;
ls -l /tmp/mnt/sda_part1/cfebackup.bin
TO->
ls -l /tmp/mnt/sda1/cfebackup.bin

admin@RT-AC66U:/tmp# mount
rootfs on / type rootfs (rw)
/dev/root on / type squashfs (ro)
proc on /proc type proc (rw)
tmpfs on /tmp type tmpfs (rw)

sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw)
usbfs on /proc/bus/usb type usbfs (rw)
admin@RT-AC66U:/tmp# ls -l /tmp/mnt/sda1/cfebackup.bin
-rwxrwxrwx 1 admin root 262144 Dec 31 12:18 /tmp/mnt/sda1/cfebackup .bin
I guess now see above the checking worked?

Well making a backup of the CFE is in dd-wrt slightly different,i have used these commandline to make backups, please correct me if am wrong.

The biggest differents i saw was the file size the asus-wrt has cfe of 256kb and the dd-wrt has one of 2048kb Question anyway these are the commands ive used in dd-wrt;

to make copy of both CFE;

dd if=/dev/mtd0 of=/tmp/cfe.original
dd if=/dev/mtd0 of=/tmp/cfebackup.bin
OR->
cat /dev/mtdblock0 > /tmp/cfebackup.bin
cat /dev/mtdblock0 > /tmp/cfe.original


works for copy on dd-wrt
cp cfebackup.bin /tmp/mnt/sda_part1
cp cfe.original /tmp/mnt/sda_part1

if u think this was an error please contact me with PM or leave a comment here Shocked esspecially with the attachements?? Mad

The way i flashed the ac66u was i did an hardreset bij using a 30-30-30 at WPS button, than i started the asus router builtin recovery mode, turnof router press reset, turnon wait 15 sec until the powerled flickers very slowly, than go to 192.168.1.1 and dont forget to set an static internal ip first.
Upload the trx dd-wrt file, wait at least 15 minutes
than repeat the hard reset step 30-30-30 and i also did an factory reset but that was more a buggy test, now u can have fun with the DD_WRT enabled Asus router Wink

To prevent network issues i recommend everyone who uses my CFE files to use mac address clone function in the setup page, this works ok.just use the mac address that is behind the back of ur router, for wifi u could use a begin octet of 02:00:00:xx:xx:xx
