Overall, openssl is a pretty invaluable toolkit that we’ll probably look at more and more on this site. To test with port 25, assuming we can use a generic client again we’re going to change the port number and because SSL can work with smtp directly we’re going to use starttls to do so:Ī valid connection would result in similar output to the following:ĭepth=3 /L=ValiCert Validation Network/O=ValiCert, Inc./OU=ValiCert Class 2 Policy Validation could also initiate a new instance of an SSL listener, using s_server or just test the connection timer using s_time. We could test smtp using the same, whether you’re using port 25 and requiring a certificate or another port.
The output would then look similar to the following:ĭepth=3 /L=ValiCert Validation Network/O=ValiCert, Inc./OU=ValiCert Class 2 Policy Validation Authority/CN= In the following example we’ll tell openssl to be a generic client (s_client) and connect (-connect) to over port 443: For example, if you have a web server you might traditionally attempt to telnet into port 80 and check you banners however, if you have an SSL certificate on it then you might be better served connecting to port 443 using the openssl command. Here’s one I solved for a work colleague Problem Word 2007 document with a stubborn ‘DRAFT’ watermark that won’t budge, despite going to the section and trying to remove it the usual way ( Page.
How To Remove Watermark In Word For Mac 2011. For starters, you’re going to use the openssl to test connections. Click OK The watermark is applied to the document. When you’re testing connectivity to servers and you’re using SSL on those servers then your traditional ways of testing connectivity may been a little augmentation.
