This is a step-by-step guide: How to setup pptp vpn server on linux (fedora 14) It looks like that the only PPTP server on Linux that had any influence was Poptop , which was last updated in 2007. There doesn't seem to be much interest in keeping pptpd up-to-date on Linux, and the reason could be that PPTP itself isn't much secure. From Wikiperia : PPTP has been the subject of many security analyses and serious security vulnerabilities have been found in the protocol. The known vulnerabilities relate to the underlying PPP authentication protocols used, the design of the MPPE protocol as well as the integration between MPPE and PPP authentication for session key establishment. In fact, the maintainers of PPTP Client and Poptop recommend...

In my opinion, the version without body content is pretty much useless (the <c:set> tag is a lot more meaningful for this purpose). If body content exists, it is inserted into the page if the testCondition is true . Optional attributes var and scope may be specified. If var is specified, a variable whose name is the value of var is exported to the associated scope ( pageScope if no scope is specified). The type of the exported variable is Boolean and its value is the value of the testCondition . <c:choose>, <c:when>, <c:otherwise> These tags imitate the Java control structure if...else...

Follow these steps to prevent form double submission in struts: In the action class leading to the display of the form, call saveToken(request) In the action class handling the form submission, check the validity of the token by calling isTokenValid(request) . If token is valid, reset the token by calling resetToken(request) , then continue processing the form submission. Otherwise, skip form processing since it's double submission. How doe it work? saveToken generates a unique token and saves it in the session under the key org.apache.struts.action.TOKEN . When the form is rendered, the struts html:form tag generates a hidden field named org.apache.struts.action.TOKEN . Upon form submission, isTokenValid compares the token stored in the session with that submitted from the form. If they are equal, return true....

The first time you access an SSH host, you'll get and store the host key. Putty stores the host key in the registry. If you run putty plink as a Windows service, the host key should be available to the Windows system user. Otherwise, plink won't connect to the remote server. The solution is to obtain the host key from an interactive session then save it for use for the system user. Here are the steps: 1. Access the remote host interactively with putty or plink. Accept the host key. 2. Run regedit and export the key HKEY_CURRENT_USER\Software\SimonTatham\PuTTY\SshHostKeys . You'll get something like this: Windows Registry Editor Version 5.00 [HKEY_... 3. Edit the exported registry file, change HKEY_CURRENT_USER to HKEY_USERS\.DEFAULT : [HKEY_USERS\.DEFAULT\Software\SimonTatham\PuTTY\Ss... 4. Import the...
