+### Locating ssh keys

+### Generating ssh key pair with rsa
+The algorithm is selected using the `-t` option and key size using the `-b` option
+```bash
+ssh-keygen -t rsa -b 4096
+```
+##### other algorithms are 
+-   `rsa` - an old algorithm based on the difficulty of factoring large numbers. A key size of at least 2048 bits is recommended for RSA; 4096 bits is better. RSA is getting old and significant advances are being made in factoring. Choosing a different algorithm may be advisable. It is quite possible the RSA algorithm will become practically breakable in the foreseeable future. All SSH clients support this algorithm.
+-   `dsa` - an old US government Digital Signature Algorithm. It is based on the difficulty of computing discrete logarithms. A key size of 1024 would normally be used with it. DSA in its original form is no longer recommended. 
+-   `ecdsa` - a new Digital Signature Algorithm standarized by the US government, using elliptic curves. This is probably a good algorithm for current applications. Only three key sizes are supported: 256, 384, and 521 (sic!) bits. We would recommend always using it with 521 bits, since the keys are still small and probably more secure than the smaller keys (even though they should be safe as well). Most SSH clients now support this algorithm.
+-   `ed25519` - this is a new algorithm added in OpenSSH. Support for it in clients is not yet universal. Thus its use in general purpose applications may not yet be advisable.

+### Add ssh public key to server
+```bash
+ssh-copy-id user@remote-host
+```
+##### add specific key to remote
+``` bash
+ssh-copy-id -i ~/.ssh/tatu-key-ecdsa user@remote-host
+```
+### Looking up correct ssh folder file permissions
+```bash
+stat -c "%a %n" ~/.ssh
+stat -c "%a %n" ~/.ssh/*
+```
+### Fixing the file permissions for .ssh folder
+```bash
+sudo chown -R $USER:$USER ~/.ssh
+sudo chmod 700 ~/.ssh
+sudo chmod 600 ~/.ssh/authorized_keys
+sudo chmod 400 ~/.ssh/id_rsa
+sudo chmod 644 ~/.ssh/id_rsa.pub
+sudo chmod 600 ~/.ssh/known_hosts
+```
+### Prevent `broken pipe` error 
+make config file in ~/.shh or and add this
+```config
+Host *
+ServerAliveInterval 120
+```
+or you can set either `ServerAliveInterval` in /etc/ssh/ssh_config of the client machine
+or `ClientAliveInterval` in /etc/ssh/ssh_config of the server machine

+#### Create a user to run Gitea

+#### Make user git sudoers
+```shell

+#### Find UID
+```bash
