How to Install SSL certificate in Linux Servers <p>I am trying to access https wcf web service from my application using monodevelop in Linux. The web service call is throwing the following exception</p> <blockquote> <p>SendFailure (Error writing headers) at System.Net.HttpWebRequest.EndGetRequestStream (IAsyncResult asyncResult) [0x00043] in /home/abuild/rpmbuild/BUILD/mono-3.4.0/mcs/class/System/System.Net/HttpWebRequest.cs:845 at System.ServiceModel.Channels.HttpRequestChannel+c__AnonStorey1.&lt;>m__0 (IAsyncResult r) [0x0001d] in /home/abuild/rpmbuild/BUILD/mono-3.4.0/mcs/class/System.ServiceModel/System.ServiceModel.Channels/HttpRequestChannel.cs:219.</p> </blockquote> <p>when I try to load the web service url using https, the Firefox browser is giving a warning:</p> <blockquote> <p>"This connection is Untrusted"</p> </blockquote> <p>The certificate(.cer) is generated using Visual Studio 2008 makecert utility.I tried to install certificate using the below commands </p> <ol> <li>certmgr -add -c -m My MyCert.cer</li> <li>certmgr -ssl <a href="https://myserver.com:1200/Monik/TestSvc" rel="nofollow">https://myserver.com:1200/Monik/TestSvc</a></li> </ol> <p>But it looks like the certificates are not configured properly. In some of the forums it saying that move the certificate to <strong>/etc/httpd/conf</strong> . But there is no such folder in my system</p> <p>Please let me know what I am missing?</p>
