 Posted: Fri 27 Oct '06 4:42 Post subject: Apache 2.2.3 with OpenSSL 0.9.9[dev] |
 |
|
Has anyone managed to build successfully Apache 2.2.3 with OpenSSL 0.9.9[dev]? I've done so as I need to use OpenSSL 0.9.9[dev] to generate ECC cert. When I tried with openssl s_server, my client (Firefox) could browse to my site running on ECC cert successfully. But when I use my client to connect to my apache web server via 443, my client is getting the error 'Firefox can't connect securely to localhost because the site uses a security protocol which isn't enabled'.
1) Anyone encountered the same problem before? If yes, y and how to solve it?
2) How do I ascertain what ciphers my web server is using other than running openssl ciphers?
Thanks in advance! |

| The ellipitic curve ciphers in openssl-0.9.9 are not exposed to mod_ssl I think that there is a patch that you can apply but i misplaced the link. and i'm sure that there is a nessus plugin that tells you which ciphers are running on your server. |

Ciphers supported in s_server binary can you check with:
openssl s_server -cert cert.pem -key privkey.pem -www
And call then https://localhost:4433

Thanks for the advice. I have applied the patch but the same error persist. 
Is there any possibility that Apache is refusing to handshake with the client? Under what scenarios would Apache do this other than not being able to negotiate a valid cipher with the client? |

The above is what I received after I run the s_server command. But this only shows the ciphers OpenSSL support. It doesn't show what ciphers Apache is supporting, right? |

I just noticed your reply yes its normal I get that too apache for some reason loads the certificates and generates the temporary keys and parameters 4 times I just compiled apache/2.2.3 with openssl/0.9.9.9 and I applied the patch I used an ecdsa certificate with the secp521r1 curve and it worked I was able to connect using firefox 2.0 and s_client check out the logs

 Why is it that yours work and mine don't.
1)Hmm, are you using OpenSSL 0.9.9[dev]? I'm not aware there's 0.9.9.9?
2) Did you generate the ECDSA certificate from openssl?
3) Any possibility of sending your cert in PKCS12 for me to test?
4) Which release of firefox 2.0 did you tried with? I've tried with firefox 2 beta 1.
5) On what platform did you complied your Apache and OpenSSL on? I'm using W2K server with SP4.
6) I've not edited the default SSLCipherSuite in httpd-ssl.conf. Had you?
I'm trying to see what could be the difference between our configurations.
When running nmake -f ms\ntdll.mak, I've encoutered the error:
.\crypto\bio\b_sock.c(728) : error C2037: left of 'sin6_addr' specifies undefined struct/union 'sockaddr_in6'
.\crypto\bio\b_sock.c(728) : error C2037: left of 'sin6_addr' specifies undefined struct/union 'sockaddr_in6'
.\crypto\bio\b_sock.c(728) : error C2168: 'memset' : too few actual parameters for intrinsic function
.\crypto\bio\b_sock.c(729) : error C2037: left of 'sin6_addr' specifies undefined struct/union 'sockaddr_in6'
and I then commented out line 728 and 729.
I was thinking since I'm using W2K and won't need IPv6, thus commented them out.
I run nmake -f ms\ntdll.mak a second time and error the error:
rc /fo"tmp32dll\libeay32.res" /d CRYPTO ms\version32.rc
link /nologo /subsystem:console /opt:ref /dll /out:out32dll\libeay32.dll /def:ms/LIBEAY32.def @C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\nm5DB.tmp
ms/LIBEAY32.def(7) : warning LNK4017: DESCRIPTION statement not supported for the target platform; ignored
LIBEAY32.def : error LNK2001: unresolved external symbol IMPLEMENT_ASN1_SET_OF
out32dll\libeay32.lib : fatal error LNK1120: 1 unresolved externals
I then remove IMPLEMENT_ASN1_SET_OF from ms/LIBEAY32.def
Have you encountered these 2 errors? Any impact in what I've done?
Greatly appreciate your advise. Thanks very much!!! |

| I'm using openssl 0.9.9.9[dev] i got it from ftp://ftp.openssl.org/snapshot/. yeah i generated it using openssl. I am away at the moment but i will email you a cert in pkcs12 as soon as i reach home. I got firefox 2.0 from here http://www.mozilla.com/en-US/firefox/. I compiled apache and openssl on a windows xp sp2 using vc 2005 .net but i didnt encounter any errors .I didnt change the ciphersuites |

Hi,
I've got the connection working fine now. But am not sure what trigger it to be ok. I just did a new compilation of OpenSSL and Apache (with the projects and patch).
Thanks very much for your help. Knowing someone has got it working definitely motivated me!  |
