From the Cisco Administration Guide:

Quote
Your device supports two user accounts for administering and viewing settings: an administrative user (default user name and password: cisco) and a guest user
(default user name: guest).

I presume you're logging in as the admin user?

Thank you. Quite pricey and above what I would be prepared to pay.  :o

That's Cisco. So I can't tempt you with one of their 8GB memory upgrades at $4,000.  :'(

yep I was aware of two user accounts from instructions and I definitely use admin account, i've never attempted to use guest account.

All in all a shame.

any advice on a broadcom based modem with strong vpn features and option to run full bridge mode incase I eve need it. Bridge mode option eliminates asus on official firmware unless 3rd prty firmware offers bridging only as an option?. wifi capabilities are not a must. would like to avoid billion if possible....

One last quick test would be to try invoking shell from the CLI prompt . . . just in case.

No, thank you.  :o

tried and nope, comes up bad command.

I'm boxing it up sunday...

is there anything modem wise that comes close to Draytek but with broadcom? I know chipsets shouldn't matter in this day and age however  withrespect to my line, I have definitely noticed better performance on broadcom chipset and ours is a Huawei FTTC with BDCM....

I work from home and travel quite a bit overseas with work so robust VPN is a must. I also need to manage the household..... like I said 5 kids 1 wife yikes....

Do you actually mean "combined modem/router"?

You mean a VPN to allow you to "dial-in" to your home network?

Hi Dray,
Yes combined modem/router not really too bothered in its wifi capabilities as I will be running with eero mesh behind it for (family) wifi. I would need modem/router to handle the VPN tunnels and allow me to dial in and it would need to be able to connect a network drive.....

If you still have the router connected perhaps you might indulge a little further. Among many other commands the router also supports the dumpmdm command:

It was found by @highpriest in the thread VMG8924-B10A unbranded supervisor password that the ZyXel routers dumped the 'supervisor' user password when this command was run. On the ZyXel, when logging in as supervisor, the 'sh' command then becomes available. Does the dumpmdm command work on the Cisco, if that so, is it the same as the ZyXel and dumps usernames and passwords?

But surely that relies upon first gaining access to the Busybox shell:-\

Most likely, but wondered whether some of those commands were hidden but available directly via the Cisco CLI before getting to the shell. So in the same way that in the ZyXel commands such as brctl and ifconfig are not displayed when entering help, but can still be executed from the ZyXel CLI.

If you want to explore the firmware in more depth I've converted the JFFS2 to little-endian (for Intel/AMD x86 based systems), extracted the root file-system and made it browsable online on my web-site as well as downloadable as a TAR archive.

I've also included a mount.sh shell script for Linux PCs to enable direct local mounting of the RV134W.le.jffs2 image. The script is commented so it should be easy enough to figure out.

You'll see it does include the /bin/xdslctl program.

Anyone know if the latest firmware for this unit has a page showing the dsl stats added in?
