a Free Certificate Authority Debugging SSL communications Introduction The SSL and TLS protocols have become the de facto standard for securing error in sslv3 read client certificate a network communications. These protocols provide confidentiality, authentication and message integrity, but add error in sslv3 read client certificate b additional complexity to client server communications. This situation is most evident when application maintainers and system administrators need to error in sslv2/v3 read server hello a debug application-layer protocols protected by SSL. This article will discuss two utilities (ssldump and openssl) that can help debug applications utilizing SSL. How SSL Works The SSL and TLS protocols

define the rules SSL clients and servers use to communicate with each other. These rules specify the order in which messages are sent, the format of each message, and the way cryptographic algorithms are applied to network communications. The SSL and TLS protocols use a layered communications stack, and define several message types. The bottom layer of this communication stack is called ssl_connect:sslv2/v3 write client hello a the SSL record layer. This layer accepts protocol messages and application data from higher level protocols, adds SSL specific headers, and hands these messages ( often referred to as SSL record layer messages ) to TCP to be transmitted. The SSL and TLS connection setup process consists of four stages. The first stage allows the client and server to negotiate security capabilities, such as the public-key algorithm, the symmetric key algorithm, and compression algorithms. The second stage allows the server to transmit digital certificates and key information to the client, allowing the client to validate the identity of the server. The third stage allows the client to exchange key information with the server, and optionally authenticate itself with a digital certificate. The final stage allows the client and server to use the negotiated parameters. The openssl utility can be used to connect to an SSL-enabled service, and print each stage described above:$ openssl s_client -connect mail.prefetch.net:443 -state -nbio 2>&1 | grep "^SSL"SSL_connect:before/connect initializationSSL_connect:SSLv2/v3 write client hello ASSL_connect:error in SSLv2/v3 read server hello ASSL_connect:SSLv3 read server hello ASSL_connect:SSLv3 read server certificate ASSL_connect:SSLv3 rea

with certificates / error in SSLv3 read client certificate B Messages sorted by: [ date ] [ thread ] http://lists.freeradius.org/pipermail/freeradius-users/2013-January/064661.html [ subject ] [ author ] Hello! I have a huge problem with freeradius 2.2.0 on my eisfair server (www.eisfair.org) and users using certificates to http://serverfault.com/questions/279189/openssl-handshake-failure-14094410-erroneous-client-certificate-check-from-m authenticate. first of all: this should not be a "how must I config my freeradius to work?" problem. These installation with these certificates and these error in config worked for over 8 month very well. And suddenly I got the problem. Every client with user/pass works still fine. The problem is about the users with certificates (windows xp and android). the certificates are not outdated: list of active certificates: V 13-01-28 13:16:17 Z 01 unknown /C=DE/ST=Somewhere/O=Manske EIS/OU=Radius_Managment/CN=Manske Radius/emailAddress=xxx in sslv3 read (the server certificate) V 14-02-17 13:16:54 Z 02 unknown /C=DE/ST=Somewhere/O=Manske EIS/OU=Radius_Managment/CN=User Name/emailAddress=xxx (one of the problematic user certificates) I tried it with check_crl = yes and no changes before the problem occurs: I updated openssl-packages from Internal Program Version: OpenSSL 1.0.0j also included the old version 0.9.7m also included the old version 0.9.8x to Internal Program Version: OpenSSL 1.0.1c also included the old version 0.9.8x But I did this over three days before the errors occured. In the meantime freeradius worked well. So, here is a shorten output of radiusd -X (I hope I do not shorten important things - btw, are there parts of such an debug output I should keep secret?)

This works successfully for most clients, but requests from a specific phone model (Nokia 2690) are showing a bizarre handshake failure. It looks as though OpenSSL is either requesting (or attempting to read an unsolicited) client certificate from the phone (which is especially bizarre because j2me's kssl implementation doesn't support client certs). I've disabled client certificates with the SSLVerifyClient none directive in both the virtual host conf and the modssl conf.
