-</code>
-===== VPN Client Access =====
-Follow the instructions corresponding to your workstation's operating system below.
-**NOTE:** You will need VPN credentials for each machine/workstation you intend to connect to the Sepia VPN.  **Client credentials can not be used on more than one machine at a time!**
-==== Linux ====
-<code>
-sudo [apt-get|yum] install openvpn
-sudo mkdir -p /run/openvpn
-## Fedora 28 and later
-cd /etc/openvpn/client
-## All others
-cd /etc/openvpn
-sudo wget https://filedump.ceph.com/sepia-vpn-client.tar.gz
-sudo tar zxvf sepia-vpn-client.tar.gz
-# Generate client credentials
-# USER should be your desired username and HOST should describe your workstation
-# e.g., dgalloway@thinkpad
-sudo ./sepia/new-client USER@HOST
-# Submit the command output in your ticket
-# After you've been notified in your ticket that access has been granted,
-sudo service openvpn restart
-OR
-sudo systemctl restart openvpn@sepia
-OR
-sudo systemctl restart openvpn-client@sepia
-# Try all 3.  One of them should work.
-# Whichever works, enable the systemd service
-sudo systemctl enable openvpn@sepia
-OR
-sudo systemctl enable openvpn-client@sepia
-</code>
-=== Linux Gotchas ===
-You may need to edit ''user'' and ''group'' in ''/etc/openvpn/sepia/client.conf'' depending on what user the service runs as.  This could be ''nobody'', ''nogroup'', or ''openvpn''.
-<code>
-sed -i 's/nobody/openvpn/g' /etc/openvpn/sepia/client.conf || sed -i 's/nobody/openvpn/g' /etc/openvpn/client/sepia/client.conf
-sed -i 's/nogroup/openvpn/g' /etc/openvpn/sepia/client.conf || sed -i 's/nogroup/openvpn/g' /etc/openvpn/client/sepia/client.conf
-</code>
-----
-If you're using OpenVPN for any other VPN connection (e.g., Red Hat's), you may need to change the ''dev'' name in ''/etc/openvpn/sepia/client.conf''.  See below.
-<code>
-# ERASE
-dev tun
-# REPLACE WITH
-dev sepia0
-dev-type tun
-</code>
-----
-If the ''new-client'' script throws an error about ''/usr/bin/python'' not being found, run:
-<code>
-sudo sed -i 's|/usr/bin/python|/usr/bin/python3|g' sepia/new-client
-</code>
-=== Troubleshooting ===
-Please disable SELinux on rhel clients
-To troubleshoot your VPN connection, try running the following command to determine where the connection is failing:
-<code>
-openvpn --config /etc/openvpn/sepia.conf --cd /etc/openvpn --verb 5
-OR
-openvpn --config /etc/openvpn/client/sepia.conf --cd /etc/openvpn/client --verb 5
-</code>
-==== Fedora NetworkManager GUI ====
-  - Make sure you've followed all the prerequisite steps [[vpnaccess#linux|here]]
-  - Right click the NetworkManager icon
-  - **Edit Connections**

-  - Enter the second line in your ''/etc/openvpn/sepia/secret'' file for **Password**
-==== Fedora Network Manager GUI -- Fedora 34 ====
-This procedure was confirmed to work on Fedora 34 on 14 July 2021.
-   - Make sure you've followed all the prerequisite steps [[vpnaccess#linux|here]]
-   - Right click the NetworkManager icon
-   - Select **Settings** --> **Network**

-   - Enter the second line in your ''/etc/openvpn/client/sepia/secret'' file for **Password**
-==== Mac/OS X ====
-Tunnelblick and Viscosity are two clients known to work with the Sepia VPN.
-=== Tunnelblick **UNTESTED** ===
-  - Download and untar the Sepia VPN client [[https://filedump.ceph.com/sepia-vpn-client.tar.gz|tarball]] <code>
-mkdir /etc/openvpn
-cd /etc/openvpn
-wget https://filedump.ceph.com/sepia-vpn-client.tar.gz
-sudo tar zxvf sepia-vpn.client.tar.gz
-# Generate client credentials
-# USER should be your desired username and HOST should describe your workstation
-# e.g., dgalloway@thinkpad
-sudo ./sepia/new-client USER@HOST
-# Submit the output of this command in your ticket</code>
-  - Replace the line ''auth-user-pass sepia/secret'' with just ''auth-user-pass'' in client.conf
-  - Follow [[https://tunnelblick.net/cConfigT.html|Tunnelblick's instructions]] for adding the config
-  - When prompted for user/pass, enter username USER@HOST as above, and for password use the secret contents of the file ''/etc/openvpn/sepia/secret''.
-  - Save to your keychain if you wish
-=== Viscosity ===
-  - Download https://filedump.ceph.com/Sepia.visz
-  - Download https://filedump.ceph.com/sepia-vpn-client.tar.gz
-  - Import the Sepia.visz config into Viscosity
-  - Extract sepia-vpn-client.tar.gz
-  - Save ''sepia/ca.crt'' somewhere
-  - Run ''sudo ./sepia/new-client USER@HOST''
-    - Replace ''USER@HOST'' with your desired username and machine description.  (e.g., dgalloway@laptop)
-  - In Viscosity, under the Authentication tab, set:
-    - **Authentication:** SSL/TLS Client
-    - Check **Use Username/Password authentication**
-    - **CA:** to the ca.crt file you saved earlier
-    - **Tls-Auth:** ta.key
-  - When connecting to the VPN for the first time,
-    - Enter your ''USER@HOST'' combination as the username
-    - Enter the second line of ''sepia/secret'' as the password
-  - Save the credentials to your keychain
-  - You can now delete any downloaded and created files (except ca.crt)
-===== A Note About DNS =====
-Due to complexities around adding nameservers to various Linux distro VPN clients, our OpenVPN server does not use the [[https://openvpn.net/index.php/open-source/documentation/howto.html#dhcp|dhcp-option DNS]] option.
-Instead, we serve our private DNS records publicly.  Your machine should be able to resolve hostnames under the ''sepia.ceph.com'' subdomain automatically.
-If you're using dnsmasq, you can add ''server=/sepia.ceph.com/172.21.0.1'' to ''/etc/dnsmasq.conf''.
