I also have TP problems on a frequent basis, and I switched away from Frontier and the actionteck modem and went back to Brighthouse/Spectrum which uses a true pass-through modem and I use my WRT1200AC V2 modem running standard Linksys firmware.<br /> <br /> Things run much better, but I still have TP problems myself. Visitors have no issues at all.<br /> <br /> <span style="white-space: nowrap;">My regions run on four Fedora linux servers here on my local network.</span><br /> <br /> I have felt the issue was how things are configured as the TP issue is random like this original post talks about.<br /> <br /> <span style="white-space: nowrap;">Here is how my region INI files are all set up is this correct?</span><br /> <br /> <span style="white-space: nowrap;">InternalAddress = 0.0.0.0</span><br /> <span style="white-space: nowrap;">InternalPort = 9182</span><br /> <span style="white-space: nowrap;">AllowAlternatePorts = False</span><br /> <span style="white-space: nowrap;">MaxPrims = 100000</span><br /> <span style="white-space: nowrap;">ExternalHostName = tsim.us.to</span><br /> <span style="white-space: nowrap;">RegionType = "Archipelago - Tropical"</span><br /> <br /> <span style="white-space: nowrap;">I use a dynamic name service for my domain of tsim.us.to</span><br /> <br /> I have not tried your debug suggestion yet, as I have no idea what I should be looking for.<br /> <br /> I see different results when I TP sometimes I arrive with no troubles, sometimes my viewer simply closes, and I have to relog, and sometimes I wait for a long time and then end up not TP's. Many times if I first go to LBSA and then back to one of my regions everything usually works, but not always.<br /> <br /> I am convinced it has something to do with loopback, but the WRT1200AC supports that function.<br /> <br /> Tom<br /> <br /> <br /> <br /> <br /> -----Original Message----- From: Fred Beckhusen<br /> <span style="white-space: nowrap;">Sent: Tuesday, May 23, 2017 10:56 AM</span><br /> <span style="white-space: nowrap;">To: <a href="mailto:opensim-users@opensimulator.org">opensim-users@opensimulator.org</a></span><br /> Subject: [Opensim-users] Problems with teleporting in grid mode from simulator, instance to another instance?

<span style="white-space: nowrap;"> It appears to me that your LAN dest region did not handshake properly,</span><br /> <span style="white-space: nowrap;">somewhere at the Agent creation process, and the CAPS seed process found</span><br /> <span style="white-space: nowrap;">the destination socket was not available.</span><br /> <br /> <br /> <span style="white-space: nowrap;">I wonder how reliable it is in general. Have you been able to bulk</span><br /> <span style="white-space: nowrap;">upload a couple dozen textures reliably, or does it crash out partway</span><br /> <span style="white-space: nowrap;">through? That's a sure sign that loopback is failing. You xxx'd your</span><br /> <span style="white-space: nowrap;">IP addresses, so I believe you are using a Public WAN IP and therefor a</span><br /> <span style="white-space: nowrap;">router is involved and loopback is necessary. There are many reasons</span><br /> <span style="white-space: nowrap;">loopback can go wrong or be flaky. Perhaps posting your router</span><br /> <span style="white-space: nowrap;">brand/model number to us for future reference will help us, and maybe we</span><br /> <span style="white-space: nowrap;">can spot something for you. If this turns out to be the router, please</span><br /> <span style="white-space: nowrap;">help us update the page on the Opensimulator.org web site that we use to</span><br /> <span style="white-space: nowrap;">track which routers work and which do not. It is at</span><br /> <span style="white-space: nowrap;"><a href="http://opensimulator.org/wiki/NAT_Loopback_Routers">http://opensimulator.org/wiki/NAT_Loopback_Routers</a></span><br /> <br /> <span style="white-space: nowrap;">Troubleshooting: Check that all IP addresses in your INI files start</span><br /> <span style="white-space: nowrap;">with http:// and make sure none of the regions have http:// in them.</span><br /> <br /> <span style="white-space: nowrap;">Go to the destination region and type into the console "debug http all</span><br /> <span style="white-space: nowrap;">5". This will print out more details of the handshake that you now</span><br /> <span style="white-space: nowrap;">cannot see. You can go to level 6, but that's really verbose. The</span><br /> <span style="white-space: nowrap;">command "debug http all 0" will turn it off again.</span><br /> <br /> <span style="white-space: nowrap;">A good way to find out if it is loopback is to set your Public IP in the</span><br /> <span style="white-space: nowrap;">Opensim.INI to be the LAN IP of the server. You will also need to set</span><br /> <span style="white-space: nowrap;">your grid parameters to point to it in the viewer to be able to log in.</span><br /> <span style="white-space: nowrap;">When all Private LAN IP's are used, your router will not be involved in</span><br /> <span style="white-space: nowrap;">anything at the TCP/IP level and all traffic will be</span><br /> <span style="white-space: nowrap;">machine-to-machine. This applies to any IP's in the range of</span><br /> <span style="white-space: nowrap;">172.16.*.*, 192.168.*.* or 10.*.*.*. The Ethernet switch is still</span><br /> <span style="white-space: nowrap;">involved, though it is unlikely to be the problem as it works with a</span><br /> <span style="white-space: nowrap;">totally different protocol that carries the TCP/IP inside it.</span><br /> <br /> <span style="white-space: nowrap;">I have collected about a thousand Opensim stats on this. Current count</span><br /> <span style="white-space: nowrap;">is 784 home routers failed loopback on first try, and only 125 passed.</span><br /> <span style="white-space: nowrap;">Reasons vary: mostly loopback is just missing, but I have remoted in to</span><br /> <span style="white-space: nowrap;">some machines and seen some very troubling things. I have continually</span><br /> <span style="white-space: nowrap;">been surprised by the flakiness of some, and also surprised by how well</span><br /> <span style="white-space: nowrap;">a cheap one from Comcast worked.</span><br /> <br /> <span style="white-space: nowrap;">Some examples: TCP appears to loop back, but not UDP. A major brand,</span><br /> <span style="white-space: nowrap;">Actiontech, widely used by FIOS, cannot loop back reliably from LAN</span><br /> <span style="white-space: nowrap;">IP:port to a different LAN IP:port (which sounds like your situation),</span><br /> <span style="white-space: nowrap;">but will loop back to the same machine very reliably. There are European</span><br /> <span style="white-space: nowrap;">ISPS that charge extra fees for loopback, (and require you to pay them</span><br /> <span style="white-space: nowrap;">to set up port forwarding, too). Some ISP's loopback at the Central</span><br /> <span style="white-space: nowrap;">Office and lose a lot of packets in the process. There are routers with</span><br /> <span style="white-space: nowrap;">only a 1K UDP loopback buffer appear to work but are flaky on teleports</span><br /> <span style="white-space: nowrap;">and bulk uploads.</span><br /> <br /> <span style="white-space: nowrap;">Some routers block the Public IP:PrivatePort ( typically 8003)</span><br /> <span style="white-space: nowrap;">configuration by looping back outside on the WAN side of the firewall,</span><br /> <span style="white-space: nowrap;">thus hitting the router firewall that should be blocking port 8003. As a</span><br /> <span style="white-space: nowrap;">result, Groups, XBakes and Profiles will not work. This took me many</span><br /> <span style="white-space: nowrap;">months to find as I am stupid about some things and believe the</span><br /> <span style="white-space: nowrap;">documentation. You cannot fix it by moving the Private port (8003) to a</span><br /> <span style="white-space: nowrap;">different port, either. I've seen several people "solve it" by opening</span><br /> <span style="white-space: nowrap;">Port 8003 to the public, which is a Bad Idea. Use LAN IP: Private Port</span><br /> <span style="white-space: nowrap;">everywhere you see PublicPort: Private IP in Groups, Xbakes and</span><br /> <span style="white-space: nowrap;">Profile. Or use <a href="http://localhost:Private">http://localhost:Private</a> Port for standalones.</span><br /> <br /> <br /> <span style="white-space: nowrap;">Fred Beckhusen/Ferd Frederix</span><br /> <span style="white-space: nowrap;">Outworldz, LLC</span><br /> <span style="white-space: nowrap;"> <a href="http://www.outworldz.com">www.outworldz.com</a></span><br /> <br /> _______________________________________________<br /> <span style="white-space: nowrap;">Opensim-users mailing list</span><br /> <span style="white-space: nowrap;"><a href="mailto:Opensim-users@opensimulator.org">Opensim-users@opensimulator.org</a></span><br /> <span style="white-space: nowrap;"><a href="http://opensimulator.org/cgi-bin/mailman/listinfo/opensim-users">http://opensimulator.org/cgi-bin/mailman/listinfo/opensim-users</a> </span><br /> <br /> _______________________________________________<br /> <span style="white-space: nowrap;">Opensim-users mailing list</span><br /> <span style="white-space: nowrap;"><a href="mailto:Opensim-users@opensimulator.org">Opensim-users@opensimulator.org</a></span><br /> <span style="white-space: nowrap;"><a href="http://opensimulator.org/cgi-bin/mailman/listinfo/opensim-users">http://opensimulator.org/cgi-bin/mailman/listinfo/opensim-users</a></span></div>
