+I use to always pass a key when sshing ex:
+
+```shell
+$ ssh -i ~/.ssh/de2 travis@vxxxxxxxxxxxxxxxxxxx.megasrv.de
+```
+That can be a bit annoying. I know two fixes:
+
+# add private key to ssh-agent
+
+```shell
+$ ssh-add ~/.ssh/de2
+```
+
+Now when you ssh you need not include the `-i ~/.ssh/de2` because the ssh-agent will find it
+automatically.
+
+*\*note: this resets once you reboot*
+
+# configure individual host
+
+You can configure individual hosts to use a spefic private key my editing your `~/.ssh/config`:
+
+```
+Host de2
+    HostName vxxxxxxxxxxxxxxxxxxxx.megasrv.de
+    User travis
+    IdentityFile ~/.ssh/de2
+```
+
+Now you only need to
+
+```shell
+$ ssh de2
+```
