Boadband @ home

Finally have 24×7 Internet access at home via 24online. Speeds are not all that good, but surely beats dial-up. Also I’m in a scheme with unlimited usage. Its was only 200 bucks more then the 500MB/month limit.

Quite an easy setup too. I have a CAT6 cable pulled upto top of my place and a CAT5 from there to my machine. All I need a network card to hook on to the ISP. Only issue is, I have to use a client to connect. Without using the client, the router does not let any of the packets from my machine though. Luckily there is a linux client 🙂

Hopefully with this, I should be able to get home early in the night and get work done from here.

    Client?

    What sort of client? I just have my gateway/DNS settings of the NIC set to my ISP’s, and I am rockin’.

    Found out that there’s competition for my cable provider. D’load speeds were averaging at 25KB/sec when I checked it out at a relative’s place…

    Re: Client?

    My ISP keeps track of the bandwidth usage etc of all the users. Esp people who have signed up for 500mb stuff. So this guy tracks everything via a loginID.

    So I fire up the client and it sends a UDP packet with my account info to the router

    The router associates my MAC address with my userID and adds my IP to the routing table.

    It has some accounting mechanism to keep track of how much I use

    (atleast this is what I’ve understood so far)

    Anyway I’m trying to understand how the auth works now 😀

    Linc sucks. Gandhi and me have had cable Internet using 24online for the past eight months or so, and linc’s method of extracting the code using tcpdump, et al is:

    a. cumbersome
    b. unsuccessful – I tried cutting and pasting bits a bunch of times, but could not get authorized

    Instead, we both now use this client: http://developer.berlios.de/projects/cyberoam/
    on Linux.

    It’s problem is that we need to manually type in the password every time we start up the computer, but then, it always works. Unlike linc.

    Was on sucky dial-up. I just cant take the heavy telephone bill anymore

  7. admin · July 31, 2003 Reply

    The ISP dude gave me the cyberoam by default. In that there is an option of save password. When I do that, the password hash is computer and it dumped into the conf file. I just have to take that and put it in linc.

    Anyway I am using the old client for now. But its badly designed and does not let me start it viarc.local 🙁

    I found some links and have solved the problem, mainly due to this link:

    http://www.exain.net/vike/linux/?pageid=2

    His thing is a little convoluted and RedHat-oriented. I’ve posted the modified versions on my website:

    http://amitng.net/24o/connect
    http://amitng.net/24o/start24online
    http://amitng.net/24o/script.exp

    (will be there till about Sunday)

    Assumptions: /var/opt/24online holds your 24onlineClient. Copy these scripts there and (if you are on Debian), add

    up /var/opt/24online/start24online

    to your interfaces file. And that’s done.. Automated login. 😀

    (Add “pre-down /var/opt/24online/24onlineClient -l if you want to..)

    PS: Change USER in connect and PASSWORD in script.exp to your values.

    I am also having internet access thru 24online.

    But he charges me Rs 450 pm for 30 hrs and give s me a bandwidth of 24kbps ( it’s kilobits) so pretty slow.

    Do u think it’s reasonable.

    Is there a way I can overcome this bandwidth restriction

    Re: Broadband@Home

    I didnt know about this scheme. but I think you are over paying. I am getting unlimited for 900 bucks and i get 40 – 50 kbps. I think there is a way to get more bandwidth via UDP tunneling. Let me play with it this weekend and will post about it

  11. Anonymous · August 9, 2003 Reply

    Get a load of this…

    I don’t know if I am welcome to post in this journal or not, but some of you may find this amusing…

    I pay my ISP 1000 Rs. per month (he used the 24online thing too). And for all that, I have a 5 kbps limit on my account. And with this, I am downloading Gentoo 1.4. I already downloaded the first CD (450 mb or so) and the second iso image is is being downloaded now (490 mb). And I also keep downloading loads of experimental packages for Debian. I used to use CyberClient till now (http://sourceforge.net/projects/cyberoam/). But today, I found linc (http://linc.sourceforge.net) and I think this works better than CyberClient. Besides, linc is open source and I can modify it if I want to (but I’d have to learn C++ for that *wink*). The official CyberClient too is released under the GPL but they are violating the license by hiding the source code (I mailed the author about this today, I still haven’t received a reply).

    I don’t know why my ISP does this. They have a lot of unused bandwidth and all that. One of the partners among my ISP is willing to give me a much higher bandwidth limit and he used to do that too. But now, the other partners don’t like the idea. And hence, the 5 kbps limit. If I knew some C++, maybe I could make linc ignore or increase that limit. Is there a simpler way to do this?

    Btw, LiveJournal isn’t letting me sign up. It says that a registered user must give me an account creation code or I should buy an account. I used to have an account a few months, but rarely ever used it… LiveJournal seems to have removed it or something. Could somebody go to this page – http://www.livejournal.com/invite/ – and invite me? I’d be very grateful if somebody cared to help out. My name is Vishruth (I live in Hassan city, Karnataka State, India) and my email address is vish—at—thepyromania.com (replace the “—at—” with “@”).

    Thanks.

    Hey Kalyan so did u get something out of the UDP tunneling? I desperately wanna inc my bandwidth. 24kbps sucks. It’s even poorer than dialup. Help me inc my bandwidth

    Thanks

    Sorry I have been really really busy lately. I think its possible. Just that you will need admin access on some machine on the net. You can set it up using this : http://openvpn.sourceforge.net/

    Thanks Kalyan for your reply. But I am no techie person. And I am running Windows 98. Also I don’t have the admin’s username and password. I think the software u recommended runs only on Win 2000/XP.Now what to do?

    Thanks in Advance.

    Another Thing I wanted to ask was that when I go to Network Neighbourhood option, I can access various folders of other computers that are also using service provided by my ISP.

    Is there any way I can utilize their bandwidth? I think those comps hav access to higher bandwqidths as they are internet cafe computers

    All these guys are dump sysadmins who would have never heard about ipv6. IF they can install NAT/PT on their , we could use it. But knowing these guys I really doubt if they will.

    v6 = IPv6 , the next generation Internet protocol.

    Well, you CAN host websites with “some unique global address” on your own PC while behind a LAN. Try http://manubhardwaj.net/articles/?q=2 . I had “http://ipv6.manubhardwaj.net/” globally valid and accessible for some months, until I got my new computer.

    hack 24online

    wanna hack 24online..join yahoo grp:24online@yahoogroups.com http://groups.yahoo.com/group/24online

    Ya I have one trick to share with you all
    that normaly the user of this services has the same user name and
    password so you can try some random username and same password. by
    this you will be able to access there account by changing your ip
    address to the one written in there account details. thus those
    persons who is having more then 1 system connected in lan can access
    this and can get double speed on net.
    Bye for now
    I will be back with some more tricks after some days of rnd.
    till then you all reply me.

    Yes, it’s possible to get around the Bandwidth restrcition.

    Like the topic says, yes it’s possible to get past the bandwidth restriction. And trust me, it’s no big deal. But before you go around trying to ‘hack’ your ISP, please try and understand that he(the ISP) can see everything you do and the system keeps tabs on everyone’s personal bandwidth usage. So you may get a call from your ISP within a couple of days once you do manage to ‘hack’ them. (I know this because mine called me within 24 hrs and then went onto ban my account.)

    One more thing, I am pretty sure the 24Online people read this page as much as 24Online users so try and not post any hacks/craks here. (The primary reason why I won’t post anything else here.)

    Re: Yes, it’s possible to get around the Bandwidth restrcition.

    I would not expect them to moniter anything , considering the fact that they just asssign same username and password for every user, its obvious they don’t care too much about security or misuse

  25. nubknacker · April 21, 2004 Reply

    Re: Yes, it’s possible to get around the Bandwidth restrcition.

    Yes, I agree that the ISP’s don’t care much for security. But remember it is your ISP that assigns the same username/password and NOT 24Online. 24Online is a professional company dedicated to security or so they say. I would be careful considering that my ISP is on my ass 24/7 just looking for a reason to ban me. 😛
    I wish my ISP would actually talk to me rather than talk to 24Online. The last time I kept cracking his manager password, he went to 24Online, spent 20K and got the server shifted to run with SSL. If he would have asked me how I did it, I would have fixed it for him for free. But he doesn’t even let me anywhere close to his server, fear I might look at it and ‘hack’ it.
    As a side tip, I would just like to add that don’t try to ‘hack’ your ISP. Realise they have a system in place, understand the system and try to break it or work around it, thats what I do. Hacking is very over-rated and not always fruitful, plus not everyone can do it, I admit I can’t ‘hack’ things at will. A good place to start would be by downloading 24Online user docs.
    Also, cracking manager password is quite easy, the right place to start would be by trying to understand what Mr.Rahul Mittal has been doing and the things he explains quite comprehensively on his page. But beware, it does require you to use your own brain also. 😛

    Anyone able to setup a router at their end ?

    I just went to India (Gurgaon). My dad has 24online connection (64kb) from his ISP. I took my wireless laptop and my Belkin wireless router with me. I tried to configure my wireless router to add the 172.x.x.x address but I couldn’t do it. The router kept complaining that its an invalid IP address. I’m going again in June and will try some other router before I go there.

    Anyway, has anyone successfully able to setup a router to share his/her 24online connection ? Is it possible to do that ?

    Thanks

    Re: Anyone able to setup a router at their end ?

    The ISP ties the MAC address to the IP address. So all you need to do is, change the MAC address of your router to your dad’s machine mac address.

    Easy to crash server of ISP

    24online authentication is performed locally and NOT remotely on some distant AAA server. In fact, the 24O server at your cable operator itself runs MySQL and stores all network policy and accounting data locally. Internaly, the 24O client software “connects” to the 24O server which in turn performs a “query” within MySQL. Something like this:

    [client software]—>authentication request—->[24O server]—>query MySQL—->if successful—->create iptables rule to allow traffic from your ip+mac

    Knowing this, there are a few cool vulnerable things:
    1. MAC addresses can be faked…
    2. MySQL can be crashed —> hint flood relevant port with relevant data 😉
    3. several iptables exploits exist – research those.
    4. Sniff for your neighbours MAC & ip addr. Use those to get online when they are offline.

    I have my operators 24O singing to my tune and was dead simple to crack! Its really a cheap hack of iptables+mysql and a badly put together client software!

    You may find these useful as well:
    1. 24O does not control upstream traffic – you basically have an unlimited upload capability
    2. Tell your operator that you don’t have a PC and want to use the connection for voice using a VoIP phone. He will create an unlimited connection for you without accounting cause 24O doesn’t know how to control “devices” – no pc, hence no software – then just duplicate the MAC & IP to use unlmited access.
    3. You may also find that downstream UDP streams e.g. radio, video, etc continue to work long after you run out of balance in your account! 24O can’t disconnect existing UDP & TCP streams. Check it out!!!

    More goodies comin your way – I just got myself a 24O demo server and should have the protocol figured in a few days, depending on time! What’s troubling is that 24O is charging huge money for essentially GPL software —someone oughtta do something about it!

    Re: Easy to crash server of ISP

    That’s a perfect example of understanding a system and trying to work around it or just bringing it down alltogether. Nice tips Mr.Anonymous.

    If you could be so nice and send the Server demo to me as well. I can’t get it because my ISP is the Authorised dealer of sorts for my city and the last time I requested one, he told 24Online not to give it to me. 🙁

    24 online sux

    To get as many times bandwidth of your existing connex u just need to press enter and click the 24 online client icon as many times as possible. It will give u many connexns at the same time
    u need a good ram, Enable the remember password and auto login options before doing this. the file check client instance.exe doesnt work properly on Windows xp.

    Re: Anyone able to setup a router at their end ?

    My ISP uses the 24online client too. I use an SMC Barricade wirelesss router so that my laptop can access the connection from anywhere in the house. I have given the router the IP address given to me by the ISP, and also spoofed the MAC address of the PC NIC. The Router runs a DHCP server, and does NAT. However, I cannot log in from my laptop – I have to log in from the Desktop. Which means I need to have the desktop on and logged on for no reason at all.
