I'm trying to find a common variable between all these users. Some have VOIP down + packet loss.. some just packet loss. So far most of the people who had their VOIP settings changed were on Huawei BTUs yet everyone lives in different areas under separate exchanges. It'd be cool if you guys can update that list with your BTU models too because this whole VOIP issue started when someone started fiddling with the VOIP settings remotely.. and at the same time people are starting to get corrupted downloads. Might be related, might not.

Cool

UPDATE :

Let's start a list of members affected, location & problem:

Fiberhome BTUs only have 1 profile and if I recall when I logged into pr0d1gy's Huawei when we were figuring out how to do the PPPoE stuff.. I never saw a 'jack' account in there.

But you can ask him to reconfirm seeing as he's probably the first guy on LYN to make the BTU settings backup when he wrote his guide.\

In any case, BTU settings don't just change themselves unless someone on the network or at TM's side is screwing around :/

Really? That's weird.. I don't remember seeing it when I accessed pr0d's but I could be mistaken. The only thing I noticed within the XML config file itself was the existence of two accounts to access the Huawei BTU.. one with admin privs and another without.

I have to do some testing at this point, would be cool if you can let me access your Huawei BTU seet ;D

Yes, this is one of the methods I was thinking about but I'd like to log into a Huawei BTU and check if there are any additional services running in the background that can be exploited. While the BTU runs an IOS-like interface (if you connect via ssh/telnet), you can also access its main Linux shell through the 'enable' command.

Anyway, I'm done checking out the Huawei Echolife (thanks seet!).

Obtained some really useful information.. the Echolife has 4 basic ports which are open at all times (and listening), TCP 80, 22, 23 and 8011. TCP 80, 22 and 23 and blocked from WAN/LAN access using an inbuilt iptables firewall. TCP 8011 however, is open at all times and I'm not sure what it's being used for.

As for this security issue, there's no real way to change the telecomadmin and root account passwords through the GUI... you have to download the config file, modify the password and reupload it. Haven't tested it myself but it should work. You also want to look at the 'services' passwords such as the telnet and SSH pass which is root/admin and change that too.

I did however get some info regarding how we can use our own SIP devices with Unifi Will be working on that in a bit.
