Quote from Scawen :

In fact, the position packets have never been sent to the host using TCP. There is no code in LFS to support that. It has been assumed that the UDP problem is a problem at the receiving end, and a host that cannot receive UDP is considered useless.

The host must receive UDP packets from a connecting guest as part of the connection process, or the connection will not be allowed in the first place.

I've always thought the UDP problem is a problem with routers that are failing to send UDP packets back to the guest, maybe the router is forgetting the ephemeral port or something like that. But the host receives UDP on a well defined port where the user (hoster) has set up forwarding to a specific computer, so the router always knows the destination and so it's less likely that a host's UDP receive could break down.

I am surprised to hear about ISP's blocking / dropping UDP packets. My first thought is, don't use that kind of ISP. That's why I'm using Zen, it costs a bit more than BT, Virgin, and so on but instead of an awful service, I believe I know where I stand. But this is my job so I can afford a couple more pounds a month. Though on the other hand I think it ends up cheaper for me because the phone service I've got from them doesn't have a "connection charge" and rounding up to the minute. It's just per second billing. They have a bandwidth limit, rather than this "unlimited bandwidth... note : fair usage policy applies" nonsense. I believe they are an honest business, not one that tries to rip you off at every turn.

So maybe if your ISP has a problem, then to fix the problem you must change ISP.

About the skin problem :

I couldn't find any reason for glitches or slowdowns in the specific case where a skin is not available at LFS World. I can only think of the problem of searching for a skin on your own hard drive when a player exits the pits, if you have many thousands of skins, maybe the file search would take a good fraction of a second, or maybe more in some cases. But that would not be any worse if a skin is unavailable at LFS World.

Anyway, I agree with the thought that it is quite annoying when people insist on joining with a skin they have not uploaded to LFS World. There is no point in using a skin if no-one else can see it. I've taken a couple of days' break from the track editor functions I've been working on, to implement a host-side check to make sure your skin exists. This feature spectates you immediately if you join with an unavailable skin.

Mate, there is only one ISP here in the country and it was working just fine right before the update. Something happened in the new update which made all people from UAE invisible while joining in...

Anything ?

Check this for more details please http://www.lfsforum.net/showthread.php?p=1772706

I cannot believe Scawen hasn't replied for this yet.

The new update prevents the player from sending his position using TCP. It is only locked on UDP which my ISP blocks. The previous versions had both TCP and UDP as options. NOW, only UDP and cannot be changed.

I cannot play LFS anymore....

Seriously ? Scawen ? anybody ?

Hello,

I had started a thread earlier http://www.lfsforum.net/showthread.php?t=69788 about this problem, in which I was fixing manually...

Long time ago until the last day before the patch was released, I used to press CTRL+T (To "Requesting TCP Positions") before entering any server so I can view and send position to the server and can play normally. That was my "fix", the problem was there and if I didn't press CTRL+T I wouldn't be able to play, send, or receive player positions.

Now, I do the same process, I see players' positions but they cannot see me, insim cannot see me, my LFS (or My Laptop) seem to be unable to send my position to the server. Doesn't matter if I use TCP/UDP (TCP makes player positions visible atleast, while UDP makes them invisible, so I am sticking to TCP) nothing helps.

I can join, can drive, but am invisible... Nothing sees me. I'm all ears listening and need some help..

Thanks..

Hello all


I'm really annoyed about one problem that is happening with me ..

Okay, I have upgraded my connection to 16Mbits / 1 Mbits (fiber lines) to improve my games performance..



I still face issues with TCs servers especially when lots of players are in. I always end up losing connection for unknown reasons. As Nitros requested to "tracert" the server. Here are the results.


Also, here is a quick run using WinMTR:


I also have to press CTRL+T to "Request TCP for Position updates" everytime i join any server, otherwise, i will not be able to spot any player.

-------

Extra info:

-Win7 x64
-AVG Internet Security 2011
-Computer > Router > Fiber Unit > Internet





Please help <
more winMTR results (via fiber unit directly)




WinMTR results (via router then fiber unit)




-----------------


Another test done by Process Monitor.

The last 5 secs is when I lost connection to TC Server, Hope this helps ..

Here is what happens with me, series of photos of me connecting..








And here I press CTRL+T, and directly I see other players..

Quote from morpha :

CTRL+T requests position updates via TCP, which is less efficient than UDP. What is your reason for doing that? Doesn't it work with UDP?

I'm pressing CTRL T cuz when I enter the server I see everybody at PITs not moving .. So I have to press it so it refreshes my TCP and gets everybody's position correctly ..

Hey people !

I have a problem, im a newbie in networking so bare with me

When i join anyserver i have to press CTRL T to get the TCP port .. but i have to do that everytime !! Before i used to join without a problem but recently this problem is here .. I wanna get rid of it !!

Let me know how i can fix it


I have Mcafee, linksyswag120n ..... LFS is trusted on Mcafee so i dunno what to do ..
