问题 My goal is to get the list of web site names from remote server. But I'm getting the exception: The RPC server is unavailable. Here is the code: public List<string> GetWebSites(string serverIP) { List<string> names = new List<string>(); DirectoryEntry Services = new DirectoryEntry(string.Format("IIS://{0}/W3SVC", serverIP)); Services.Username = "user name"; Services.Password = "password"; IEnumerator ie = Services.Children.GetEnumerator(); DirectoryEntry Server = null; while (ie.MoveNext()) {

问题 After reading List of IP Space used by Facebook: "Real" list is the last answer, but I wonder how Igy (with the answer marked as solution) managed to shrink the list a lot by adding consecutive classes into a bigger one (by decreasing accordingly from network mask for each new consecutive network), is there a tool, or only manually ? This is a HUGE improvement for firewall, where number of rules counts (the shorter the better). 回答1: A simple solution is to use netaddr: import netaddr ips =

问题 I want to calculate the security cost of middlebox traversal when VM migrate from one physical server to another. Middle boxes can be firewalls or IPS/IDS containing rules checking the VM traversing them. Now imagine the most simple scenario that the only problem is to find the cost of checking VM by middlebox rules (this is what I call it security cost), and according to this cost finding the optimum path. However there are already some protocols out there such as BGP or OSPF, but

问题 Question - would like to allow access to Fabric & Crashlytics from our server which means that we need to allow it through our firewall for access. Can anyone share the domains or IPs that we should allow through ? Secondly, we would also like the fabric plugin for Android Studio and Xcode to work, would the above domains and IPs also apply ? 回答1: Mike from Fabric and Firebase here. We don't support IP whitelisting as our IP addresses can and do change quite frequently. You should whitelist

问题 how to get the current logged in user on non secured pages? I have only an /account/ page which is secured through the firewall and the other pages are unprotected. My global navigation has the following template (simplified): {% if app.user %} <a href="/account/data">... <a href="/logout>... {% else %} <a href="/account/login">.... {% endif %} Problem: The navigation with the logout link should be accessible on unsecured page too, but there is no UsernamePasswordToken...and symfony displays

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 8 years ago . I need to implement secure data transfer from client to server (binary data). I'm looking for the solution that doesn't require clients to configure firewall exceptions. Obvious choice is HTTPS. Most firewalls
