Why does IP keeps on changing?

3g

Just would like to let you know that this morning it is working fine again. I actually managed to upload more than my previous record of six files.

For the record, during my night rest last night my PC was switched off and nothing have changed in my settings. It can also not be a cache or anything funny problem because yesterday while I was spending hours and hours of my time to sort this out, I rebooted about 6 times. I cleared the cache ai did that ipconfig/flushdns thingy in cmd line and those reboots did not cause your service to all of sudden work normally again. I even completely switched off my anti virus and the windows firewall in an attemp to use your service as it should be.

So I doubt that it got something to do with my PC. My host have on numerous occasions when this happen confirmed that there is nothing wrong with the server.

So my only conclusion is that it is one YOUR side. I know you guys love to put the blame on the user but there is something terribly wrong on Vodacom's side and you guys do not want to admit it.

It seems to me that each time that I have this problem I can work fine in the morning but later on it becomes a hassle. Perhaps the problem starts when more people enter the network.

My guess is that your network cannot handle the number of users using it and that is why your users cannot enjoy the service they pay for.

I would like to see where Vodacom (or myself) 'love to put the blame on the user'? Or that 'there is something terribly wrong on Vodacom's side and you guys do not want to admit it'

You seem to like coming out with guns blazing with unfounded accusations. Last time Vodacom 'stole your money' remember? And when it was pointed out that you were spending money on your credit card (after you made how many accusations on this forum), you just went quiet. I would have thought, after all these unfounded accusations you made, an apology would have been in order.....even an "oops, my mistake" would be cool.

The spirit of this forum is to work together to resolve problems, not to point fingers with no resolution.

In any case, the only thing we're interested in is getting any problems on the network resolved. For this we sometimes need your help. Without specific information, we cannot figure out a problem, especially when it's intermittent or multiple problems/symptoms.

You're the guy on the ground, and in your case, the only report we have of this 'twin IP'' problem. So we need your help.

On not wanting to get to know new stuff, I once read this inspirational website that preaches one should always be willing to learn new stuff and not come up with excuses. Here's an extract for you:
http://www.pietpetoors.com said:
One thing I find hard to understand is that you can show people what to do, you can give them the recipe and still they will come up with excuses like:

I do not know how (I also did not know how, but had a passion to find out, all software packages have a help file which will show you how. I am a Metallurgical Engineer, not a web designer, I have not attended one web design course, I learned it all via internet tips and software help files, that means that anybody can do it if they really want to)

I do not have time ( I also did not have the time, that is why I worked until 3 in the mornings to make sure that it does not stay like that the rest of my life)

So let's rather work together and get this resolved. From what I understand it looks like you see two specific situations:

1) The twin IP problem.
2) FTP transfer problem.

But I'm not sure. Your posts aren't clear enough to deduce any specific info on where to start looking for the problem.

On the 'twin-IP' problem. If you can explain to me exactly how to emulate the problem, I'll do so and do some tracing. I've never used these tools, but am quite willing to learn and will make the time. Even if it's 3 in the morning!

On the FTP problem, we've been able to duplicate a problem where, when the FTP server switches sockets, it stops. I'm not sure if this is what you're seeing (again. more detialed info is required), but if so, it is already under investigation.

So, if you can start by giving clear feedback on how the problem occurs and how to duplicate it, I can try and replicate. Then we can trace and resolve.

Thanks for the reply vodacom3g. As a test I setup a secure connection on my server and logged in, no problems. Both servers use server side issued certificates, so should be the same. He is running Plesk, I am using Cpanel. Mine is a dedicated server, his a shared account. Perhaps I can PM you the info etc. to test?

Please do. And your contact details, if you don't mind :). I'll probably give you a call to better understand all this stuff. I come from an X-windows environment!

Then you can see a lot more than I do. I use Total Commander to do ftp. All I can see is that it connects, start to upload files and then while uploading one of the files just freeze. I do not know where to go and look what happened or why it is stopping I do not even know what a socket is. So if you can see that there is a socket switch or something I am very grateful. Hopefully we will then resolve the one issue then. If you resolve it please let us know what was wrong so that we know where to point the support team to when it happens again.

As I said this morning, this morning it is working 100% fine. Perhaps it is a good idea to look at the "getting logged out" problem as well at the same time. I do not know if LED experience the same, but each time when I have these problems they go hand in hand. If I cannot ftp I also get logged out of the secure server and vica versa. When the one problems goes away the other one also disappears.

Have a look at the very first post of this topic.
What happened was that I first complained to my host for about a week that I get logged out from the control panel. They logged in and had no problem. So the one day after about the 20th complaint with them, I was trying to setup a new email address on the one domain which took about 50 log in attempts to get it done. While I was logging in and getting logged out the one support guy emailed me and asked why my IP keep on changing. So I told him I had no idea I am connected to 3G and I was working continuously and am not connecting and disconnecting all the time. So he sent me the log and that is what I posted on the first post.

The server support then suggested that that is the main problem. Because the control panel sees a different IP it logs me out for security reasons as soon as I have a different IP and they also suggested that this could also be the reason why the FTP boms out. I have tried just about every ftp program on the marked and then realized that it is not my ftp program, this took me about 3 days.

So to answer your question. I do not know how to emulate the problem. To me with my limited understanding of how your systems work it is easy, use Vodacom 3G to connect and it is there by itself.
 
Oeps Ah I did it again

OK, here is a way to check it.
So I made 100% sure I have only ONE computer switched on. I opened VMC light and I connected to the Internet. The baloon said VMC Light now connected. SO as far as I am concerned this is ONE connection. If I made any mistakes so far, please advice me.

I then went to http://whatismyipaddress.com/
The pages loaded and it displayed the images you will see at
http://www.pietpetoors.com/vodacom/1.jpg

I then just left that web site on and continued working.

I DID NOT disconnect at any time and as I type I am still connected with the original connection. So if I am correct this still seems like ONE connection.

As I worked I went back to that page every now and then and clicked the refresh button. And Whala, my patience paid off.
see
http://www.pietpetoors.com/vodacom/2.jpg
You will note that in the first image my IP was 196.207.41.251 and in the second one it was 196.207.41.252

If I remember correctly when my host reported it to me it was also the difference between 253 and 254, so iet seems like it is only the last digit that jumps between two numbers, whatever this might mean. The fact is that my IP is changing while I am connected on the same connection.

This is good (in a sense) as it removes the secure console thing from the equation.

Can you give me the times you did the above, i.e. when did you connect and when did you take the above 2 snapshots? Also, just to confirm 100% again, the 3G data number and the area you were in when you did this.

I'll request a trace to help.
 
3g

I cannot give you the exact times, I will keep an eye and record it the next time. The time I saved the files was 15h50 and at the time I was connected for some time, I guess more than 10 minutes but are not sure exactly how long.

My 3G number is 0795156006 and I am in Langebaan, as far as I know we use the Mykanos tower.
 
Again

It happened again at exactly 19h52, this time I did not waste time with the screen shot because it looked exactly as the previous one. I have been connected for 12minutes 46 seconds now and transfered 2.14 Mb
 
3G problem

It was again with the IP ending on 251 and 252, again I only have one PC working at the moment.
 
It happens more frequently now than this afternoon. It happened again at 19h57:50 and I have now been connected for 17:42 minutes.
 
IP change

And guess what, just I thought it would be, I now get logged out of the control panel all the time and ftp is not working. It is now 20h00:42
 
3G problem

It happens all the time now. Some times it stays on 252 even after 5 or 6 refreshes.

See, just about every time when we have the problem it is later in the day and especially late at night. I think this is when everybody is home and playing games or whatever other people do on the Internet instead of making money.

SO then eventually I give up and go to bed. The next morning I start up the PC and everything is fine.

Thus Mier's Theory on the first page of this topic makes a lot of sense to me with my limited knowledge of this subjetc. Mier said
To preserve public IP's Vodacom probably does a many(private addresses) to few (public addresses) NAT.
When you connect to the Internet the 10.x.x.x address is NATtted to a 196.x.x.x IP address. This link between your Internal and External IP is valid only for a short time to preserve the amount of public addresses needed by Vodacom.
When the connection is idle the public IP address is made available to someone else. When you use the connection again, the NAT is build from scratch and you may get a new IP.
It's likely that this is a UDP application, therefore the timeout will be very short.

Disconnected for a while and connected again. The same happened at Wednesday, August 29, 2007 at 8:28:27 PM with the same IP address. Am connected for 02:26 minutes now.

I concur on this issue. I have internetvpn APN for public rather than the 10.x.x.x for private so I can VPN. My last IP address changes 196.x.x.233/232 whilst on line continuous. It only ever alternates between these two last nos. No-ip keeps me up dated, probably answers my VPN "dropped connection" occasionally. Just a little validation to the history.
 
Piet, Essexman, to confirm: This on the internetvpn apn?

Please do an ipconfig in a DOS-box and post this IP together with the one you get from http://www.whatismyip.com.

If you see the online IP change, please redo the ipconfig and post both IP's again.

So for every check you do, redo the 'ipconfig' and refresh the web page and post both IP's here please.

On the internetvpn apn these two IP's should be the same, if they're not, we might have a transparent proy messing around.

Won't you post the full IP's and also what your IP is at that time using 'ipconfig'?

Where are you?
