Was told that VIP5 subscribers may end up having to pay for some of the "premium" HyppTV channels but free for VIP10 and VIP20 subscribers. Don't ask me what those "premium" channels are

I saw a note on their hypptv web page a month or so back saying that certain channels will be premium channels (cbeebies was one of them) and chargeable on 1st september onwards.

I only got my unifi on 1 sep, and when I choose cbeebies there's a charge of 3 or 5 "points" per month to subscribe to it. I'm not sure if there was such a charge before 1 sep or not.

You get 100 free points a month, the technician said you can top up by calling their call center and it will be charged to your bill. I don't know how much it costs though.


btw, does anybody know where I can get a cheap HDMI switch? What are the prices like in Pasar Road? My TV has only one HDMI which is being used for my mythtv pc right now. I saw a HDMI switch in all-it for RM400, not worth paying that to watch hypptv.

I was a bit skeptical about the large downloads being corrupted problem (as TCP/IP is error correcting), but seems it is quite true.

I just tried downloading the Ubuntu 10.10 netbook beta from here:

http://ubuntu.bytecraft.com.my/releases/10.10/

The MD5SUM for this file should be:
10bec11e0ab5a9c195289b861b71e51e ubuntu-10.10-beta-netbook-i386.iso

But on checking my download, I got this instead:
9e5f29f2c5aeb04056529c8ba16eb255 ubuntu-10.10-beta-netbook-i386.iso

There were no errors during the download. And since it is over TCP, if it was any corruption in the line during transmission, it should have been taken care of by the network stack already. Unless the network stack is faulty ...?

Interestingly, bytecraft also makes their files available over HTTPS, which adds an SSL layer over the TCP stream. SSL has another level of error checking, separate from the network stack. In real life, SSL should never see an error when it is running over TCP, as TCP already does error checking and corruption. However, this is what I got (ignore the warning about certificates):

» Click to show Spoiler - click again to hide... «


Well, wget gave up after 20 SSL errors. But it's a pretty convincing demonstration that something is definitely wrong.

I would consider UniFi totally unusable for anything more than "for fun" at this rate, certainly not for work or business transactions. I wonder how long this has been going on for? I just got my UniFi a few days ago.

I noticed when looking at VOD previews, there is a corruption in the data every 30-90 seconds ... the image becomes blocky like astro just when it is about to start raining. I wonder if this is the same corruption affecting our downloads?

Don't see it on livetv however.

Anyone else seeing the same? And why isn't livetv affected?

It's persistent attempts rom the same IP, keep changing TCP ports from 1xxx to 4xxx
even got port number labeled with radacct, zephyr-clt, etc ....
it seem to me some kind of random port scan & attempt to comes in, an act resemble hacking ....
So is this kind of action "normal" for UniFi ??  hmm.gif
This kind of action is "normal" for the Internet.

With the whole world connected, there's bound to be a few thousand hackers out there scanning ports and IPs, and you're bound to get hit by some of them.

Yes, I'm lucky behind NAT+Firewall, but I do have some ports mapping running behind NAT, what if it manage to scan and got the right port?? shakehead.gif
and what about those without firewall??

Sigh, this is really annoying and I only realise now .....
*
If it manages to scan and get a port that is open, it will be able to communicate with whatever application you have mapped to the port. Most of the time, if it doesn't speak the right "language" for that applications communications, nothing much will happen, usually the app will just hang up and wait for the next connection.

Most apps that give access to critical things (like your data for example) will have some sort of id and password scheme, and so the problem will not get past that.

Where the risk is is that if the app has a bug and the bug is well known and allows some remote exploit, then you have a problem. In fact, this is really what the port scans are looking for. Which is why, if you are opening ports, you are responsible to make sure you keep your software up to date.

Those without firewall/router who run (especially) a windows PC directly on the internet ... deserve what they get! *grin*

My VOIP has been down the last few days, today I logged in to the BTU to take a look.

My SIP number and password were correct, but there was an entry "jack" below that ...

Attached Image

I unticked "enable" on that account, and applied the settings and immediately my VOIP light came back up, and I had a dial tone and could dial in and out.

Since I didn't make a backup of the config after installation, I'm not sure if that entry should be there at all ... though I suspect not. Can anyone confirm?

Removing "jack" doesn't really fix much. It's closing the barn door after the horse has bolted.

(1) The entry being there demonstrates that someone has had access to your BTU.
(2) If they can create a SIP entry, they can pretty much make a backup of your BTU config.
(3) The BTU configuration (which when saved is just a text/XML file) contains your SIP id and password.

So let's say you secure your BTU, and remove the "jack" entry.

A few months down the road, you notice some calls in your bill that you did not make. Then what?

Fixing the bigger issue is a network wide case; someone higher up in TM needs to address this. I would think at least they would need to:

(1) Do a proper audit of the BTU and ensure that there are no obvious backdoors.
(2) Change all the default BTU passwords to unique ones.
(3) Only when that has been done, change all the SIP passwords.

That's a major exercise, it needs someone with real guts/no ego issues to admit the problem and institute the changes from a higher level.

On our side right now, what is the best way to protect ourselves against having to pay for extra calls on our phone bill? Not just this month but in the future? Assuming we end up logging a billing dispute months down the road, what supporting evidence do we need to have established at this point? Do we write in to TM and to who and about what? Make a police report about a "break in" (that might actually get some attention, especially if the press is involved)??

Just lost all unifi services here in BRP, Sungai Buloh around 15:40 today.
Friend in nearby Damansara Damai also experiencing same thing.

Wonder if this is going to be an internet-less / phone-less raya ... ?

-- edit --

Phew! Everything came back to life 10 minutes later.

-- edit --

VDSL users still down though. Mine is on fiber.
Any VDSL'ers got theirs back yet?

Hi guys,

Just ran some test with "shahada":

1. download big file from: http://ubuntu.bytecraft.com.my/releases/10...etbook-i386.iso
speed about 420~500kb/s  (with uTorrent & DC++ on), took about 25min to complete

2. download checksum file from: http://www.toast442.org/md5/
run MD5, drag & drop the big iso file into it, select "Generate Checksum" and click "Run", the result:
[attachmentid=1771510]


So I supposed it seem ok no loss packet right?
But when I run Pingtest the result:
user posted image

I ran few times, it's about 1~3% packet loss, so what does it means? Got packet loss in my case or not?? rclxub.gif

Btw, my current connection as follows:
HuaweiBTU[LAN1] ----> [WAN]Buffalo WHR-G300N (dd-wrt with VLAN2.500 tagging & PPPoE profile)
HuaweiBTU[LAN2] ----> [WAN]DIR615[LAN4] ----> IPTV

I'm keeping my RB250GS for emergency, meanwhile I just want to use that DIR-615 gao-gao first!! tongue.gif

Yeah, if your checksum is 10bec11e0ab5a9c195289b861b71e51e the file is correct. On mine, I got different checksums and the file is corrupted.

Packet loss is a slightly different issue than the corrupted downloads ... With packet loss it means that some of the packets being sent from one side to another didn't make it. It could either be a router along the way dropped it due to being overloaded, or it got corrupted along the line and the receiving network equipment detected the corruption and dropped the packet. Packet loss is "not too bad an issue" as the higher level of the network stack (TCP) will request the other end to retransmit missing packets. So at the end of the day when it reaches your application (browser, ftp, whatever) you will see "perfect" data. The only downside to packet loss is that slows your transfer, as the receiver has to re-request packets when it sees something missing.

The data corruption issue is a bit more sinister though ... in a proper network, the TCP level checks the integrity of the data and requests re-transmission of bad packets, so the application level sees perfect data. Yet those facing the data corruption problem are not seeing any errors ... but still getting bad data. It means somewhere along the path from the two ends, the network stack is not doing the right thing.

I can live with some packet loss but not data corruption!

I'm trying to figure out the spread of those facing the data corruption issue and if there is any common denominator. It seems though that only SOME users are seeing it, not all. I'm also wondering if it is something at the home side or the center.

I asked klseet to test as I thought he was using the RB250, if you get data corruption problems on that it means the dlink is innocent. 8-) Since i have the problem, I guess I have to wait till I get hold of a RB250 to prove that.

Hi,

In addition to my home VIP5, I have a BIZ20 with 5 fixed IP for my office. I was away when the BIZ20 was set up, and TM set it up pretty much standalone from my office network. The staff have been testing it out by using the WiFi on the DIR-615 so far.

Today finally got to the office so played around with it. From what I've seen the setup on the DIR-615 connects over PPPoE and gets my first fixed IP, and they've set up a local LAN that does NAT behind it.

I Reconfigured the DIR-615 with rizvanrp's config to make it bridging only, and set up my router (centos PC with multiple NICs) to run a pppoe to it, and I get my first public IP on the router. Works fine up to here.

I'm wondering though, how and where my other 4 IPs are to fit in to this picture. I have the subnet mask details, etc, but am just not familiar with how multiple IPs work with a PPPoE configuration.

Can anyone familiar shed some light on this? At least at a logical network level? I guess it would be similar to Streamyx + 5 fixed IP configuration -- not that I know how that looks like either.

-- edit --

kind of solved this one already ... 8-)

For those that may need it, here's a script for connecting a Linux/Ubuntu PC to UniFi directly (i.e. without a router). The script can either support connecting to your BTU via :

(1) A D-Link running in vlan bridge mode or Mikrotik switch doing vlan tagging or
(2) Direct connection of PC to BTU (*without* d-link bridge or mikrotik).

You can use this if all you have is one Linux PC to be connected to UniFi, or perhaps your router is screwed up and you just want to temporarily get a Linux PC online. Or, if you're a bit more adventurous, you could use it as part of a Home Linux Router solution (just add another ethernet card and setup NAT and connect your other PCs).

I tested it with Ubuntu, though it should be portable to other Linux distributions. There are some settings at the top of the script you need to set.

I haven't got IPTV working (my netbook has only one ethernet port), but there are some barebones code in there you could try out. If you come up with fixes to get IPTV it working, please let me know.

» Click to show Spoiler - click again to hide... «


Save the file as "run_unifi_pppoe.sh".

To run it just execute "sudo sh run_unifi_pppoe.sh". To stop it, press control-C in the terminal you ran it from.

If you want it to come on automatically, and stay running, add the following to your /etc/inittab file:
» Click to show Spoiler - click again to hide... «


Don't forget that with this, your Linux PC is directly on the internet. Make sure you have secure passwords, and disable unnecessary services. Better still, install a firewall script.

I'll add some notes for UniFi BIZ with 5-fixed IP package later.

May I know what kind of equipments you have on your UniFi?

Strange, it seem like many of you have corrupted download recently, I just tested 2 scenario yesterday downloading a ubuntu iso no problem at all:
1. HuaweiBTU + Buffalo WHR-G300N [dd-wrt, PPPoE with vlan2.500 tagging]
2. HuaweiBTU + RB250GS + WHR-G300N [dd-wr, PPPoE only no vlan tagging]

I NEVER user DIR-615 for internal at all, no since day 1, now this piece of junk I only use it for IPTV.

So are you guys using DIR-615?
*
I connected my laptop directly to the BTU (Linux with VLAN + PPPoE sw) and got connected to unifi, and did the same test download, and *STILL* got the data corruption problem. So that pretty much eliminates the DIR-615 or any equipment on our side of the network. It looks more like it's coming from TM's side ... in other words, we can't do much about it ourselves.

From the list, it seems it's mostly northern klang valley users -- Kota Damansara, Damansara Damai, Sungai Buloh, BRP, Kepong affected. There are also people who have no issues at all (my office line in Hartamas downloaded the test file fine yesterday -- although I really should test a few more times).

Anybody in central or southern klang valley affected?
