Fedora :: Get Openssl To Verify A Certificate?
Jan 8, 2011
I am trying to get openssl to verify a certificate. I will walk you through what I have done so far.
1. openssl genrsa -des3 -out connect.mydomain.com.key 2048
2. openssl req -new -key connect.mydomain.com.key -out connect.mydomain.com.csr
3. Bought an SSL from GoDaddy.
4. Submitted my CSR
5. Downloaded sf_bundle.crt (CA File I presume)
6. Downloaded connect.mydomain.com.crt
Now I can do the following: [root@server tls]# openssl verify -CAfile sf_bundle.crt connect.mydomain.com.crt
connect.mydomain.com.crt: OK This is specifying the CAfile.
[Code]...

I am testing about using SSL Certificate in apache web server using Ubantu 10.04.2 (64 bit edition). And I insert SSLcertificate and private.key file into "default-ssl" file in "sites-available" folder. But when I call the website, SSL certificate show "Could not verify this certificate for unknown reason".
Configuration in "default-ssl" is shown below
SSLCertificateFile /etc/apache2/ssl/mysite_com.cer
SSLCertificateKeyFile /etc/apache2/ssl/privatekey.key
SSLCACertificateFile /etc/apache2/ssl/SCAONE.cer
SSLCACertificateFile /etc/apache2/ssl/ROOTCA.cer

I've been trying to get an ECDSA certificate to work for my postfix installation, however, it seems that when I try to use the aECDSA protocol with a client the server gives "no shared cipher" errors.
I had created the certificate like so:
Code: Select allopenssl ecparam -name secp521r1 -genkey -param_enc explicit -out private/ec-email-server.pem
openssl req -new -x509 -key private/ec-email-server.pem -out certs/ec-email-server.pem -days 365
So I've setup a test server, and connected to it with a test client like the following:
Code: Select allopenssl s_server -accept 123 -cert /etc/ssl/certs/ec-email-server.pem -key /etc/ssl/private/ec-email-server.pem
openssl s_client -connect localhost:123
However, once again, I get "no shared cipher" errors.

We installed 3 new rhel 5.5 systems yesterday; each of which are generating this error " Error: certificate verify failed" in response to a basic "yum update". From what I can gather, via a general search, this may be isolated to x86_64 -- however the references I found were specific to Satellite Server (which we are not using). Never the less, I checked the PATHs for the cert and they are correct. All of our 32 bit systems are running RHEL 5.5 and this is not a problem on any of them.

this is not on the master node, but rather the node that is being replicated to. The problem occurs when i query using ldapsearch or an `getent passwd` EG ldapsearch:
Code:
[root@cakeslave ~]# ldapsearch -x -b 'cn=Christian Unger,ou=People,dc=example,dc=org' -D "cn=replica,dc=example,dc=org" -H ldaps://cakeslave.example.org -w cakewalk
ldap_bind: Can't contact LDAP server (-1)
additional info: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
[code]....
The cacert.pem in /etc/ssl/certs and /etc/openldap/certificate are identical (check using md5sum). I have done an strace and found that it looks at /etc/pki/tls/cert.pem .

I'm unable to compile ruby 1.9.X and I found out it was related to openssl, although it seems there's a patch available for ruby I don't know how to apply it so I was thinking on downgrading to openssl 0.9.8n
I'm using F13 btw, I'm still posting it here as openssl 1.0.0 was first introduced on F12, the other major distros are still using openssl 0.9.8k so there's no much information on the problem

I'm using Apache as a web server and mod_ssl to handle my certs. Everything was working fine on Fedora 11 running 0.9.8x of openssl until I updated to 12. Version 1.0.0beta4 of open ssl is full of bugs. It is basically incompatible with .net and php's implementation of SSL. Running wireshark actually shows it fails at handshake stages...
I'm not here to report the bugs relating to openssl but can somebody please explain why there is an unstable version of openssl in Fedora 12 as standard?

I'm on F13 and I'm trying to compile a package from the source. The package is delasa (www.dalesa.lk) and when I ./configure. I get 'configure: error: openssl development libraries not found'. This is the output of 'yum search openssl | grep dev'

I'm having trouble understanding how to verify the download of the Fedora iso-files. know how to do this on a Windows system. I have been looking in the help section for checking the iso-files, but I'm not sure where to find the right hashes, like MD5, SHA1, and etc.

I want to verify the root password. I am using rPath linux and my use case is like this: 1. There is screen in my application through which user can change the root user's password. He provides 2 information in the screen
i. existing password
ii. new password
2. I use a shell script in the back end that uses the "passwd" command to do it. And it doesn't ask for the existing password. But, my business use case is if user enters wrong existing password, I should not reset the password and throw some error message. How do I verify the existing root user's password? And also keep in mind that I am already in that linux box (logged in as root). Also let me now if there is any smarter way of doing it other than "passwd" command.

I need to run a proprietary VPN client (Aventail) that can't use the openssl libraries that are packaged with 64bit F10:The Fedora openssl package does something differently from the original openssl.org package that makes it incompatible with Aventail (see bugzilla ticket 477073) I also believe the Aventail client software requires 32-bit libraries. So, I've determined I need to install 32bit openssl directly from openssl.org, then link my Aventail client to that. Note that I don't want to replace the 64bit openssl libraries currently on my system.
Based on the Bugzilla ticket, I believe I know how to hook up Aventail before I install it simply by supplying a few specific soft links if I can make/compile/whatever the 32bit openssl.org libraries and keep them in their own isolated directory. how to get the 32bit openssl libraries installed in a little corner by themselves on my 64bit system. give a step-by-step on on the commands necessary to place a 32bit version of openssl all by itself in a directory of my choosing?

I just downloaded the "Fedora-11-i686-Live-KDE.iso" and "Fedora-11-i686-Live.iso". I want to check if the downloaded files correct or not. I can use a tool to get the md5 sum of the downloaded files. But I want to compare them with the original ones.

I am trying to run Citrix XenDesktop on F13.I installed the .rpm package from their website and when I access my school's server, firefox acts like everything is ok but then I get a certificate error. A box pops up that says You have not chosen to trust "AddTrust External CA Root", the issuer of the server's security certificate (SSL error 61).' and I am not sure how to handle this.

I upgraded from F11(x86_64) to F12 with no reported errors. (expected an update session to follow, but it didn't.)
Tried a manual "yum update" and it aborted with a notice that libssl.so.8 was not found (required by python-2.6.2). I didn't find anything useful at wiki.linux.duke.edu/YumFaq.
The DVD installs python-2.6.2-2 (8/21/09) and openssl-1.0.0-0.10.beta3 (10/16/09). /usr/lib/libssl.so.10 is a symbolic link to libssl.1.0.0. libssl.so.8 is not found, really.
I thought of replacing openssl with one from F11 but it was required by too many packages - couldn't remove.
I tried to find a later rpm of python, but couldn't locate any Fedora directories with individual packages.
I've searched the web and the forums. What am I missing?

i tried to install f13 from live cd and failed. i have 2 questions. i do not understand how to setup partitions according to scottro's message. It says you need small ext3-formatted /boot partion and a ext4-formatted root partition. Does this configuration have to be setup before you boot into the live cd? If so, please tell me how to set this up. my pc is pentium d with 2 hard drives. The master hd is has xp, ubuntu8.04, and swap partitions. I would like to use one-half of the slave drive for f13.
Second question. I would like to be able to verify download of fedora-13-i686.iso. I downloaded it to my xp partition and installed Windows MD5summer. Where or how do i get the md5 file for this iso file?

So i wanted to set a new one on Fedora 14, there is the problem..On my fedora 14, i tryed to use the configuration file that i've made on the F11 but withtout success. It seems that when i activate the SSL option on the server it does not want to start anymore... and i have no errors messages. I notice that when i desactivate the SSL "ssl_enable=NO" my server on F14 can start normaly.

I am having issues with using OpenSSL. How do I view the currently used certificate? Also, do you know of a good site that has instructions on how to install a certificate. The previous user installed a GoDaddy cert for an FTP server and I need to update it because it's expiring real soon.

Got F13 installed yesterday, this afternoon I suddenly started getting Secure Connection Failed warnings. I'm not sure whose problem it is because it mentions uses an invalid security certificate.This certificate is only valid for *.opendns.com(Error Code: ssl_error_bad_cert_domain)It continues to say that someone could be impersonating the actual server. I am still receiving mail through google and my google calendars seem to be working. I do use OpenDNS for my DNS instead of my ISPs (Comcast which would very often slow down) and obviously I use IMAP mail with google on Thunderbird. So is it google, or OpenDNS, or Thunderbird that has a problem. Firefox does not seem to have a problem

I want to enable sshd from Internet, but I want to secure it as much as possible.Therefore, despite the fact that the service will run on a tcp port above 2000 to prevent most scans, I would like to :- First, force the use of a client certificate, to avoid brute force attack on my users/passwords- second force the use of a username/password to avoid someone having access to my system just by stealing my key..When I look at the configuration, it's possible to enable both, but one of them is sufficient to login, but I can't find how to make them both mandatory...

My organization just moved to using a zscaler proxy system. Basically, I have to use a .pac file in Firefox to get onto the proxy, which directs me to a series of two Flash pages, one to input my username, one for the password. After reading through the .pac file, I was able to get some command-line things to work by specifying the proxy given at the end. However, this server uses an SSL certificate that is not emitted by an authority, but rather directly by our organization. In Firefox, I had to import this certificate to enable https:// browsing.
Is there any way to "import" this certificate so that yum can use it? Because yum freezes with the error:
Code:
Could not get metalink [URL] error was
14: Peer cert cannot be verified or peer cert invalid

I have a weird problem in which I try to use cryptodev in Openssl version 0.9.8g, but then if an error occurs or the system logs out, the version for Openssl rolls back to 0.9.8b.I have also tried reinstalling, but no dice. The version stays 0.9.8b. I am using Intel Tolapai with RedHat 5

I was upgrading openssl 0.7 to 0.9.81 in my redhat 9 server. I've followed the guideline from here: [url]
Now everything is messed up There's no libcrypto.so in /usr/local/ssl/lib directory. Only libcrypto.a. Neither in /usr/lib or /lib directory. I can't even run scp or wget to download rpm of openssl. Getting libcrypto.so error. I've use locate command to find libcrypto.so. There's none. I've run ./config, make, make test and make install command again in the openssl 0.9.81 source directory. But no luck. No libcrypto.so. This is a production server and the httpd went down.
