11. esn t mean that all hope is lost though To work out the above situation you will need to have multiple different IP addresses assigned to your gopher server fortunately since IPv6 stepped in having as many addresses as we need is not a problem anymore Once this is done then it s only a matter of binding every one of your gopher domain names to a different IP address The final step is running a dedicated instance of Motsognir on every IP address Example Let s imagine that I own two domains gopher example com and gopher mydomain net For these domains I d like to serve gopher content from srv gopher example com and srv gopher mydomain net respectively Step 1 configure at least two different IP addresses on my gopher server and declare them within my DNS zone to be used like this 2001 DB8 410E ABC 1 gt gopher example com 2001 DB8 410E ABC 2 gt gopher mydomain net Step 2 Prepare two different configuration files for Motsognir with different bind and GopherHostname settings like this etc motsognir gopher example com conf GopherHostname gopher exanple com bind 2001 DB6 410E ABC 1 etc motsognir gopher mydomain net conf GopherHostname gopher mydonmain net bind 2001 DB6 410E ABC 2 Step 3 Run two instances of Motsognir using your custom configuration files motsognir config etc motsognir gopher exanple com conf motsognir config etc motsognir gopher mydomain net con
12. f Page 17 21 Motsognir gopher server s manual Security considerations Security considerations Like with any unix daemon there are a few security aspects that one should always keep in mind Even the most carefully written programs can have bugs some of which could be exploited by malicious persons This is the reason why a system administrator should apply some security limitations even to simplest or most trusted daemons Run Motsognir as a non privileged non root user A system daemon is usually not supposed to be run as root In the unlikely situation where an attacker would gain control over Motsognir having the process running as an unprivileged user would greatly reduce the panel of harmful actions that could be performed on your server However there is a problem you will usually want to run your gopher server under the standard TCP 70 port and this being a low port requires the process to have root privileges That s why Motsognir provides a special configuration option called RunAsUser This option allows to set the username we d like Motsognir to use and then when Motsognir will be launched it will first open bind the listening port and only then drop its privileges to switch to the configured user Choose your file permissions wisely If your Motsognir server runs as a non privileged user then it makes much sense to limit permissions on files that it serves If the gopher server is not sup
