| 00:40.10 | randomparticle | i'm older than trees |
| 00:40.34 | TkTech | Here, there's a fair overlap between our PUG, RUG, JUG, HUG, AUG and a couple others. |
| 00:40.40 | TkTech | And the overlap is mostly the 40+ group. |
| 00:41.42 | randomparticle | you might also be aware that "you" doesn't always mean you. it sometimes means an indeterminate anyone |
| 00:43.04 | randomparticle | in the US does using "one" sound as pompous as it does here? |

| 01:14.32 | JeffM | randomparticle, you should not have to cast it |
| 01:14.51 | JeffM | (char*) + 1 moves the pointer one char over |
| 01:16.51 | randomparticle | i have this in my code: if ((uintptr_t)ptr%0x1000 == 0) { |
| 01:17.01 | randomparticle | without the cast, the compiler is unhappy |
| 01:17.03 | JeffM | what are you trying to do with the pointer? |
| 01:17.10 | JeffM | why are you moding ? |
| 01:17.28 | randomparticle | every 4KB i printf a progress message |
| 01:17.31 | JeffM | why do you care where the pointer is in the address space |
| 01:17.44 | JeffM | do you know the pointer of the start? |
| 01:18.09 | JeffM | ptr could be ANYWHERE in the address space they don't always start at 0 |
| 01:18.55 | JeffM | unsigned int size = ptr - start_ptr; if (size % whatevs); |
| 01:19.11 | randomparticle | i'm searching through all readable process VM regions |
| 01:19.20 | randomparticle | i have the start-end points of each region |
| 01:19.25 | randomparticle | set ptr to start and work through it |
| 01:19.27 | JeffM | ewww |
| 01:19.51 | randomparticle | it's a dynamic library that i load into a processes address space during a gdb session |
| 01:20.13 | randomparticle | process's |
| 01:20.47 | JeffM | so you arn't really doing pointer math, you are doing address statstics |
| 01:21.00 | JeffM | copy the pointer value (address) to an unsigned int |
| 01:21.07 | JeffM | then do your math on that |
| 01:21.34 | JeffM | or an unsigned long int |
| 01:21.42 | JeffM | on 32 bit systems it'll zero out the high stuff |
| 01:21.52 | JeffM | then they are comparable between bitness |

| 14:44.04 | DJPaddy | hello all. I 've been trying to setup a bzflag server and I can't seem to get it listed on the public servers list. I get the message "ERROR: Host mismatch for server authentication key", however the key is correct. Can anyone assist me please ? |
| 14:54.24 | khonkhortisan | the key is correct for your current public ip and you are not telling the server what to broadcast itself as? |
| 14:55.13 | DJPaddy | well from http://my.bzflag.org/listkeys/index.php I see that the key is correct, and I am giving the same description to my conf file -publicaddr games.logicsystems.gr:2929 |
| 14:56.01 | DJPaddy | when i run the server with -d option I see that it behaves differently, it gives a shorter (much sorter) ADD POST than the one seen at the wiki (http://wiki.bzflag.org/Creating_a_server) |
| 14:57.24 | DJPaddy | from what i understand I just need three options: -publictitle, -publicaddr and -publickey, correct ? |
| 14:57.54 | DJPaddy | the -p is at the correct port:2929 and at the debug I see listening on 0.0.0.0:2929 |
| 14:58.40 | DJPaddy | I also tried with IP address (generated a new key) but that didn't help |
| 15:00.33 | khonkhortisan | When someone tries to connect to games.logicsystems.gr, somehow they have to be redirected to your server, before your server sees them |
| 15:01.10 | khonkhortisan | Are you sure your server is accessible from the internet using your ip? |
| 15:01.54 | DJPaddy | well, games.logicsystems.gr is up and runnning at port 2929 and it resolves to the firewall's ip 198.107.197.28 and i have opened the ports. however I will try now a telnet to that port from an unknown ip to see if the server is accessible, one moment please |
| 15:02.24 | BulletCatcher | Because there is no reverse DNS for your IP address, I think you have to use IP address rather than host name for your key. |
| 15:02.33 | DJPaddy | it connected |
| 15:03.16 | DJPaddy | yes there isn't reverse dns that's true. I tried with IP as well didn't have much luck, let me rechange the config file and try it again, I already have created a key for my ip as well |
| 15:03.34 | DJPaddy | same thing |
| 15:03.44 | DJPaddy | however this debug message is really short: |
| 15:03.55 | DJPaddy | Tried to fetch URL: http://my.BZFlag.org/db/?nocache=1374332053 |
| 15:03.56 | DJPaddy | CURLOPT_URL is : http://my.BZFlag.org/db/?nocache=1374332053 |

| 15:04.01 | khonkhortisan | I can connect to your ip, it's a rabbit chase |
| 15:04.09 | DJPaddy | yep, and a map I am proud of :) |
| 15:04.17 | DJPaddy | it's really old, more than 10 years |
| 15:04.25 | DJPaddy | just decided to bring it back from the dead |
| 15:04.41 | DJPaddy | every time though I get * Closing connection #0 |
| 15:04.42 | DJPaddy | Got line: "ERROR: Host mismatch for server authentication key" |
| 15:05.00 | khonkhortisan | huh. ./bzflag games.logicsystems.gr:2929 worked |
| 15:05.44 | DJPaddy | yes people can connect, I just can't seem to get the server listed. I have opened both tcp and udp on the specified port for connectivity purposes, however on http://my.bzflag.org/db/?action=LIST I can't seem to find my server |
| 15:05.44 | khonkhortisan | What if you use a public address with your ip key? |
| 15:05.52 | DJPaddy | that's what I am doing right now |
| 15:06.04 | DJPaddy | changed the options of the config file to: |
| 15:06.24 | DJPaddy | -publictitle "Logic Systems BZFlag Server with the infamous pinball map v2.0!" |
| 15:06.24 | DJPaddy | -publicaddr 198.107.197.28:2929 |
| 15:06.24 | DJPaddy | -publickey <mykey> |
| 15:06.32 | DJPaddy | however I still get the same message |
| 15:07.58 | DJPaddy | on the example page (Creating_a_server) I see that the server should post a really long URL to my.bzflag.org like this one: |
| 15:07.59 | DJPaddy | Sent ADD message to list server |
| 15:07.59 | DJPaddy | GET /db/?action=ADD&nameport=24.1.104.25:51540&version=BZFS1910&gameinfo=0000000100000000000000000000c800c800c800c800c800c800c8& |

| 15:08.14 | DJPaddy | however on my debug I only see this POST: * Trying 64.31.37.37... > POST /db/?nocache=1374332137 HTTP/1.1 |

| 15:09.23 | BulletCatcher | I suspect the wiki page is out of date. |
| 15:09.25 | khonkhortisan | BZFS1910 makes me think it's version 1.10.8 |
| 15:09.53 | DJPaddy | nope, its BZFlag server 2.4.2.20130419-MAINT-linux-gnu (protocol 0221) http://BZFlag.org/ |
| 15:10.32 | khonkhortisan | 0221 is much better |
| 15:10.34 | DJPaddy | ah you mean about the wiki, yes it's obviously an older server version |
| 15:10.48 | khonkhortisan | but not as good as 0222 :P |
| 15:11.07 | BulletCatcher | The old HTTP GET method includes all of the data in the URL. |
| 15:11.08 | BulletCatcher | With the current PUT method the data is not shown. |
| 15:11.09 | DJPaddy | is there a 0222 ? I thought I downloaded the latest source and compiled it from there |
| 15:11.31 | khonkhortisan | there is, we aren't exactly using it yet, it's on github |
| 15:11.44 | DJPaddy | oh |
| 15:12.04 | DJPaddy | should I try fetching that one or is it some other parameter I haven't thought of ? |
| 15:12.07 | khonkhortisan | nah |
| 15:15.00 | DJPaddy | I think I found something |
| 15:15.14 | DJPaddy | I think it needed also the -publiclist option instead of the publicaddr |
| 15:15.55 | DJPaddy | I put it and I now see the huge POST but now I get a connection timeout :( |
| 15:16.13 | khonkhortisan | does that mean your regular list is wrong, or does it just have to be set? |
| 15:17.01 | DJPaddy | it just needed to be set, I had only publictitle, publicaddr and publickey, no publiclist line. Now I added it however although I am getting the long POST debug message I afterwards get: |
| 15:17.12 | DJPaddy | Peer 10.0.47.21 connection timeout with data "POST / HTTP/1.1\015\012User-Agent: bzfs 2.4.2.20130419-MAINT-linux-gnu\015\012Host: games.logicsystems.gr:2929Peer 10.0.47.21 connection timeout with data "POST / HTTP/1.1\015\012User-Agent: bzfs 2.4.2.20130419-MAINT-linux-gnu\015\012Host: games.logicsystems.gr:2929..... |
| 15:17.40 | DJPaddy | however I see that I can get from my server to my.bzflag.org (I lynxed the IP) |
| 15:21.29 | blast007 | let me check |
| 15:22.39 | blast007 | "Requesting address is 198.107.177.210 while server is at 198.107.197.28" |
| 15:23.05 | blast007 | ~dns games.logicsystems.gr |
| 15:23.53 | DJPaddy | huh ? let me see |
| 15:24.14 | blast007 | so the actual requests are coming through from a different IP |
| 15:24.42 | blast007 | so does the system have multiple IPs, or is that just some sort of gateway device? |
| 15:24.54 | DJPaddy | strange I think I have natted the whole server to go through the .28 address |
| 15:25.06 | DJPaddy | there is a firewall in front of the server ,let me see |
| 15:25.39 | DJPaddy | you are right, for some reason I am natted to 210. (I just did a whatismyip check) |
| 15:25.49 | DJPaddy | so it's a NAT issue. checking. |
| 15:25.59 | DJPaddy | (thank you very much for your help guys by the way) |
| 15:26.24 | khonkhortisan | blast007 gave the final help, but you're welcome anyway :) |
| 15:31.34 | DJPaddy | fixed the IP NAT rule, I am now natted to my correct address .28 however I still get this: |
| 15:31.35 | DJPaddy | Queuing ADD message to list server |

| 15:31.35 | DJPaddy | File transfer terminated with error from libcurl 28 : Connection time-out |
| 15:33.09 | DJPaddy | that makes sense. If my internal server tries to connect to its own external IP it won't loop. I tried it with the hostname |
| 15:33.22 | DJPaddy | ...and it connects |
| 15:34.25 | DJPaddy | I still don't see me on the list though :( |
| 15:34.55 | DJPaddy | There is a message already queued to the list server: not sending this one yet. |
| 15:35.05 | blast007 | could you stop and restart the server quick? |
| 15:35.42 | DJPaddy | sure |
| 15:35.52 | DJPaddy | just restarted it |
| 15:36.03 | DJPaddy | I get some "Expire Cleared" messages |
| 15:36.24 | blast007 | not seeing any request to the list server |
| 15:37.34 | blast007 | are you able to access http://my.bzflag.org/db/?action=LIST from the system running bzfs? |
| 15:37.40 | DJPaddy | let me lynx it |
| 15:37.51 | DJPaddy | yes |
| 15:37.53 | DJPaddy | I get the lsit |
| 15:37.55 | DJPaddy | *list |
| 15:38.21 | DJPaddy | um. the -publiclist option... |
| 15:38.26 | DJPaddy | I think it's wrong after all |
| 15:38.33 | DJPaddy | I set it to -publiclist games.logicsystems.gr:2929 |
| 15:38.41 | DJPaddy | i think I am trying to register me to myself :) |
| 15:39.02 | DJPaddy | removed it , restarted the server |
| 15:39.30 | DJPaddy | aaand I am registered !!! |
| 15:40.22 | blast007 | woo :) |
| 15:40.24 | DJPaddy | excellent. It seems that the original problem was the NAT. |
| 15:40.40 | DJPaddy | thank you so much guys, I will now try to jail the bzfs installation and then I am ready to go :) |
| 15:40.47 | blast007 | have fun :) |
