Hmm.. I think I would need a 2003 box myself to be able to figure this out... |
|
|
If I can remember next time I am at school, I'll boot my 2k3 server and try it out |
|
|
I was able to test unreal on "windows 2003 R2 standard edition service pack 1" today, and it didn't crash here... EDIT: Just FYI I tried it both in GUI and services mode. |
|
|
I'm using Windows Server 2003 Enterprise Edition SP1, with last hotfixes from Microsoft (Windows Update), localized Russian version. Unreal 3.2.4 crashed :( Unreal 3.2.3 works fine. Very strange problem. |
|
|
Maybe the 'R2' thing fixed it? I've no idea, I only got that machine not one without R2 (whatever it is..). Bugz, if you got some time, could you try to run Unreal on 2003? See if it crashes (when someone connects etc) :) |
|
|
Mine seems to start on Windows 2003 Standard with all updates installed. I used the most basic configuation, and no problems at all. My 2k3 has all the Windows Updates installed. Is it possible to attach a conf to this so I can have an idea on what is set? (feel free to bleep passwords and cloak keys) |
|
|
Ok, I'll try to do it tomorrow. (I have no access to my server now). |
|
|
I suppose that the problem appears only with ENTERPRISE EDITION of Windows Server 2003. It's possible that with STANDARD EDITION there is no problem. IRCd cannot start on any computer under this OS installed with any modification of unrealircd.conf, error is the same in all cases. Error appears under "cleanly installed" OS without any updates and service packs as well as under OS with SP1 and updates. === Steps of my "clean" experiment: 1. Install Windows Server 2003 Enterprise ("clean install", booting from installation CD, with creating and formatting new HDD partition). 2. Copy msvcr70.dll (344,064 bytes) into Windows\System32 directory. 3. Run Unreal3.2.4.exe (1,900,080 bytes) and install IRCd. 4. Copy Unreal3.2\doc\example.conf to Unreal3.2\unrealircd.conf. 5. Modify this file (only most important sections and parameters, file is in attached archive ircderr.zip). 6. Start IRCd. Result is ErrorScreen.png (in attached archive ircderr.zip). === What's wrong in my actions? :( Maybe some Windows configuration settings can affect this? Can you try to run UnrealIRCd 3.2.4 under ENTERPRISE EDITION of Windows Server 2003, not STANDARD EDITION? |
|
|
I'll test again on standard when I can (though I think it will just fine). I don't know anyone (irl) with enterprise edition, so no.. I cannot test it on that. I was also not planning to buy it myself, seeing it costs $5000 USD ;). |
|
|
Unfortunately, our company have only Enterprise Edition of 2003 Server... Now I have to use Unreal 3.2.3 it is a pity |
|
|
Some more information about my trouble. I suppose that problem is in resolver_channel pointer which must be initialized by function ares_init_options(&resolver_channel, &options, ARES_OPT_TIMEOUT|ARES_OPT_TRIES|ARES_OPT_FLAGS); (file res.c line 90), but I see that after this call resolver_channel==NULL! After that, during executing of function ares_fds(resolver_channel, &read_set, &write_set); (file s_bsd.c line 1753) IRCd causes exception "Read access violation", probably, because of a NULL pointer. Can you explore the behavior of ares_init_options() function thoroughly? In which case it can return resolver_channel==NULL? Incorrect work of malloc() function ("channel = malloc(sizeof(struct ares_channeldata));" at ine 96 of areas_init.c file), or maybe another reason? |
|
|
Ok. Did you try running in GUI mode btw? Might as well try that to see if it helps. |
|
|
My steps were: 1. Remove "add_remote_include", "find_loaded_remote_include", "find_remote_include" and "find_remote_include" from wircd.def file to avoid linker errors "unresolved external" in "Simple compile" mode (no SSL/ZIP/Remote includes). 2. Build IRCd with DEBUG=1 executing "nmake -f makefile.win32" (Visual Studio .NET 2003). 3. Load WIRCD.exe into OllyDBG Debugger (http://www.ollydbg.de/). (There was a difficulty with using native VC .NET IDE to debug because your sources haven't IDE project, only makefile). 4. Trace executing of WIRCD step-by-step in View Source mode. |

I'll have a 2003 enterprise system here at the end of the next week. If u need my help... |
|
|
Sounds good ;). Your first test should be to try to run Unreal 3.2.4 on it (just the one from unrealircd.com), see if it crashes. (Just to say; try that first, no compiling/etc needed, only if it turns out it really crashes at you too then compiling stuff etc would be needed). Thanks ;). |
|
|
2syzop: Today I have explored the return code of ares_init_options() function on my Enterprise Edition of 2003 server. So, after executing of int ret_code; ret_code = ares_init_options(&resolver_channel, &options, ARES_OPT_TIMEOUT|ARES_OPT_TRIES|ARES_OPT_FLAGS); I see that ret_code == -1 (instead of ARES_SUCCESS or 0). 2vonitsanet: thank you for wish to help. |
|
|
Btw, there's slightly improved error reporting in CVS (basically it should report some kind of error instead of crash). So if you are bored you could checkout latest CVS and see what you get (unreal3_2_fixes branch). |

Follow the instructions from the faqitem ( http://www.vulnscan.org/UnrealIRCd/faq/76 ) instead of trying to edit the wircd.def manually ;p. |

Current CVS compiled (was planning to put a win cvs build online anyway): http://www.syz.dds.nl/Unreal3.2.4-cvs20060226.exe |
|

Thanks. I'll try to run it tomorrow :) |
|

ADDITION: When I try to run 3.2.4 under Windows Server 2003 Enterprise installed from other distribution CD, other version (english, non-localized), error is the same. Therefore, problem is not in Windows distribution... problem is in 2003 Enterprise Edition, independently of localization. |
|
|
I have installed unreal3.2.4 on windows 2003 enterprise and it runs just fine... EDIT: windows 2003 enterprise with service pack 1 |
|
|
vonitsanet: ok thanks :P I got another report of a windows 2003 crash a few days ago... So I guess Romeo is not the only one. |
|
|
Hmm Romeo, are you sure your architecture is i386 and not amd64/whatever? In other words, you are not using a 64 bit architecture but really 32 bits? Because if you would be using 64 bits, then maybe we got the source of the problem there.. It would explain why it works at some with the exact same windows version, while not at you + a few others :P. |
|
|
I'm having the same problem. http://forums.unrealircd.com/viewtopic.php?t=3209 I'm running Windows Server 2003 SP1 x64 R2 Enterprise on an AMD Opteron 165 with 2GB RAM. |
|
|
hm k, another guy said he was using a 32 bits proc and also has this problem, so I guess this isn't much related to 64 bit after all... Just in case anyone wonders what the status of me on this is.. well.. nothing.. there's (nearly) nothing I can do, I cannot reproduce the problem here so I can debug.. it works perfectly fine (unfortunately).. additionally, the bug itself is in the c-ares libary, and I don't see why it would ever really return something like this. Now thinking of it, I can only think of adding like XX debug statements in c-ares, compile everything, and send it to one of you guys, to make it print out where it actually failed (and where it passed)... Of course that's not exactly the best debugging scenario, but I don't see any other options.. ;) |
|
|
2syzop: I am using 32-bit i386, not x64. |
|
|
It works fine on my w2k3 server Enterprise edition For some reasons, i reinstall Windows from different distributive (Windows 2003 server Enterprise Edition Service Pack 1 RUS, on same mashine, and it crashes. |
|
|
i'm not sure what's on with your win2k3sp1, but FYI: when i'm trying to skipping the message loop by "return xx;", it crashed inside ares. i guess the ares threads isn't terminated correctly if there's any bailout before message loop. |

Stack Trace: Module: wircd #0 (null):0: ares_fds It's write to wircd.* In CHANGES of c-ares 1.3.1-cvs: * December 22 - Daniel Stenberg added ares_getsock() that extracts the set of sockets to wait for action on. Similar to ares_fds() but not restricted to using select() for the waiting. Maybe if take and compile with c-ares from cvs UnrealIRCd don't crash? I try to compile, but I'm not programmer and c-ares from cvs didn't compile. |
|
|
To my knowledge, that has nothing to do with this crash (unfortunately :P), basically it's just another interface to ares so you can use poll/whatever instead of select. Oh, and, btw, the crash in ares_fds() happened because we forgot to check failure of initalization of the resolver, now it doesn't even reach ares_fds() anymore ;). So.. the bug is somewhere in the init code (of c-ares). |
|
|
* Configuration loaded without any problems .. [error] resolver: ares_init_options() failed with error code -1 [(null)] :-\ didn't create *core files, but in status window write it. |
|
|
Unfortunately, 3.2.5 also can't start in my 2003 Server Enterprise (Win32) because of ares_init_options() failure. Maybe, some information about this error is already available from c-ares's developers? |
|
|
c-ares developerts don't have windows wolontuers for testing windows part of c-ares. |
|
|
o_O One man suggest the next solution: property of wircd.exe, Compatibility, Compatibility mode - windows XP. After what he sad, that unreal start on win2003 SP1. |

Today I find strange thing. One of servers don't want start (win2003sp1). Connecting to hub going throw ISP connection don't requiring vpn-connection. I ask to make internet connection and see my eyes what happened on server. After creating vpn-connection Unreal loading without troubles o_O. And I ask to show me ipconfig /all. I've be shocked.

And Unreal is up! After this I ask Analyzer` add to settings of Ethernet card DNS servers of ISP and server start without vpn-connection. 2 Romeo: Into your server do you correct dns settings on network card? On one side c_ares is responsible for dns and as for the error return "[error] resolver: ares_init_options() failed with error code -1 [(null)] " they are right when they do it like that. On the other side unreal must start then without dns resolving but with settings from unrealircd.conf taken. I see 2 ways from this: 1) Ask about it developers c_ares. 2) See the code for startup unreal without resolvind dns. And, most important, learn admins of ircd to correct settings of server :] |
|
|
And to rephrase things a bit, Ares crashes/doesn't want to start when there is no DNS servers on any on the network connections. |
|
|
Hmm, it's a very interesting information for me... My server works in local area network, which have no any connection with Internet. All computers (including server) have local IP addresses like 192.168.1.x and DNS is NOT used (but DNS Service is running in automatic mode). It's very simple network. Also, DNS resolving is DISABLED in unrealircd.conf. What can I try to do? Tell me please in details. |
|
|
Network Connections - Local Area Connection. General - properties. Internet Protocol (TCP/IP). Use the following DNS server adresses: Just try to add 127.0.0.1. The best way - setup DNS server. Add or remove programms - Add\Remove Windows Components - Networking services. Choose Domain Name System (DNS). Install and configure it. |
|
|
Ok, thank you, I'll try to do it... |
|
|
YES!!! YES!!! YES!!! :) There's NO more problem! After specifying DNS Server address 127.0.0.1 in TCP/IP Properties of network connection in Windows Server 2003 (this field was empty earlier), Unreal starts and works fine! Great thanks to Bock! |

Perhaps not too important anymore, but.. it makes me curious. Is this a specific problem to windows 2003? Or does windows 2003 have some weird option (DNS automatic mode ??) that makes more users configure their servers without DNS or something. Or does XP/etc somehow do certain things and always have a DNS server, like a fallback to 127.0.0.1. Bock: Are you still thinking running in windows XP compatability mode fixes this? (so even if no DNS server present). Or are there even 2 bugs? :P |
|
|
2syzop: it's possible that this a specific problem to Windows Server 2003 Enterprise... because of there's no problem in Windows XP, WITHOUT specifying of a DNS Server address in connection properties. |
|
|
ok, thanks :p. interesting. I'll make it fallback to set::dns::nameserver if initalization fails. |
|
|
syzop:"Bock: Are you still thinking running in windows XP compatability mode fixes this? (so even if no DNS server present). Or are there even 2 bugs? :P" No, not 2 bugs. I ask man, he don't remember settings of server. :] I think that he forgot add DNS servers to setting of LAN. It's specific trouble of 2003, cos I ask people to remove their DNS settings on WinXP SP2 and try to start Unreal. It run. |
|
|
http://daniel.haxx.se/projects/c-ares/mail/c-ares-archive-2006-09/0000.shtml Maybe it fix bug? EDIT: No, I just try to compile with this patch and got error... |
|
|
Fixed in 32* (.564): - Windows 2003: Fixed UnrealIRCd unable to boot if no DNS server is configured, we now fallback to set::dns::nameserver in such a case. Thanks to Romeo (reporter, 0002802) and Bock for tracing this down. I've uploaded a new win cvs version at http://www.vulnscan.org/wincvs which includes this fix. If someone could confirm that fixes it on a DNS-less machine, that would be helpful. I'll leave the bug open until someone confirmed. |
|
|
[Sat Sep 23 14:55:18 2006] - [warning] Unable to get DNS server from registry. Using the one from set::dns::nameserver (127.0.0.1) instead [Sat Sep 23 14:55:18 2006] - TIME SYNCH: Unable to synchronize time: Timeout. This happens sometimes, no error on your part. I think, this bug we can close :]] |
|
|
Ok, thanks. As mentioned, was fixed in 32*. Now also fixed in 33*. |
