Setting up PrivX Components

This article describes setting up and maintaining PrivX components.

To get started with PrivX you will need to set up at least one PrivX server.

PrivX-Server Setup

PrivX servers provide PrivX services, such as the PrivX GUI and certificate-based authentication services.
Set up repositories for downloading PrivX packages and dependencies. Before installing PrivX, please update your host to ensure the latest packages:

yum update

To set up a PrivX server:

1. Set up repositories for downloading PrivX packages and dependencies.

   • On Red Hat 9 or Rocky Linux 9:

     sudo yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm
     sudo rpm --import https://product-repository.ssh.com/info.fi-ssh.com-pubkey.asc
     sudo curl https://product-repository.ssh.com/rhel9/ssh-products.repo -o /etc/yum.repos.d/ssh-products.repo
     sudo yum install firewalld
     sudo yum install postgresql-server # or postgresql if using an external DB
     sudo yum install PrivX

   • On Red Hat 8 or Rocky Linux 8:

     sudo yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
     sudo rpm --import https://product-repository.ssh.com/info.fi-ssh.com-pubkey.asc
     sudo curl https://product-repository.ssh.com/rhel8/ssh-products.repo -o /etc/yum.repos.d/ssh-products.repo
     sudo yum install firewalld
     sudo dnf module enable postgresql:13
     sudo yum install postgresql-server # or postgresql if using an external DB
     sudo yum install PrivX

   • On Red Hat 7:

     sudo yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
     sudo rpm --import https://product-repository.ssh.com/info.fi-ssh.com-pubkey.asc
     sudo curl https://product-repository.ssh.com/ssh-products.repo -o /etc/yum.repos.d/ssh-products.repo
     sudo yum install firewalld
     sudo yum install PrivX

   • On CentOS 7:

     sudo yum install epel-release
     sudo rpm --import https://product-repository.ssh.com/info.fi-ssh.com-pubkey.asc
     sudo curl https://product-repository.ssh.com/ssh-products.repo -o /etc/yum.repos.d/ssh-products.repo
     sudo yum install firewalld
     sudo yum install PrivX

   • On Amazon Linux 2:

     sudo amazon-linux-extras install -y nginx1 epel
     sudo amazon-linux-extras install -y nginx1
     sudo amazon-linux-extras enable postgresql14
     sudo yum install postgresql-server # or postgresql if using an external DB
     sudo rpm --import https://product-repository.ssh.com/info.fi-ssh.com-pubkey.asc
     sudo curl https://product-repository.ssh.com/ssh-products.repo -o /etc/yum.repos.d/ssh-products.repo
     sudo yum install firewalld
     sudo yum install PrivX

   • On Amazon Linux 2023:

     sudo rpm --import https://product-repository.ssh.com/info.fi-ssh.com-pubkey.asc
     sudo curl https://product-repository.ssh.com/rhel8/ssh-products.repo -o /etc/yum.repos.d/ssh-products.repo
     sudo yum install libxcrypt-compat firewalld
     sudo yum install postgresql15-server # or postgresql15 if using an external DB
     sudo yum install PrivX

The application binaries are installed to the /opt/privx/bin/ directory. The configuration is installed to /opt/privx/etc/ directory. Utility scripts are found in the /opt/privx/scripts/ directory.

1. To automate PrivX configuration, you may optionally define post-installation settings using environment variables. The post-installation script skips prompting for any settings found in environment variables.
   Environment variables for the post-installation script are listed in:
   /opt/privx/scripts/postinstall_env
   Export the environment variables with:

   sudo source /opt/privx/scripts/postinstall_env

2. Run the post-installation script to configure the server:

   sudo /opt/privx/scripts/postinstall.sh

Unless specified in environment variables, you will be prompted for:

• PKCS #11-keyvault settings. Enable and configure this only if using external HSM. For additional HSM-setup instructions, see the HSM articles from Deployment page

• Number of load balancers in front of PrivX Servers. Set to 0 for single-server deployments.

• The address of a NTP service.

• DNS and IP address(es) of the server.

• Database settings (if using an external database):

  • Address of the database in IP or DNS-name format. For example: database.example.com
  • Arbitrary name for the PrivX database.
  • Arbitrary name and password for the PrivX-database user.
  • Password of the PostgreSQL user postgres.
  • Notification back end to use: the existing PostgreSQL database

• Credentials for the initial superuser account.

1. Install the PrivX license to enable product functionality. You can do this by browsing to the PrivX GUI located at (replace privx.example.com with the DNS or IP address of the PrivX server):
   https://privx.example.com/
   Log in using the superuser credentials.
   In the GUI, navigate to Settings → License in the PrivX UI, and provide your license code under Online license update. Click Update, PrivX automatically contacts the license server to obtain and install your license. For more detailed information about licenses, see License Management.

You have now set up a PrivX server.

1. You may verify the status of the PrivX microservices on the status page, located at the following address (replace privx.example.com with the DNS or IP address of the PrivX server):
   https://privx.example.com/status.html

Manual PrivX package installation

Instead of installing PrivX packages from the SSH product repository, you may install the PrivX package manually as follows:

1. Obtain the PrivX RPM package. The PrivX RPM package is a file with a name like the following:
   PrivX-*.x86_64.rpm
   Where * is to be replaced with the product version.

2. Copy the PrivX RPM to your target server.

3. Install the PrivX RPM (replace `PrivX-.x86_64.rpm`* with the path of the PrivX RPM):

   yum install PrivX-*.x86_64.rpm

Setting Up Optional Components

This section provides setup instructions for optional PrivX components.

PrivX Extender Setup

PrivX Extenders relay host connections, allowing connections to target hosts that are inaccessible from PrivX servers.

To set up PrivX Extender:

1. Obtain an Extender configuration. Either:

   • Create a new Extender configuration, or
   • Download an existing Extender configuration.

   You can create and download Extender configurations via the PrivX GUI at Administration→Deployment→Deploy PrivX VPC/VPN Extenders.

1. Install the PrivX Extender software on the Extender host in either of the following ways:
   Install from the SSH product repository. To do this, set up the repository and install the software package:

   • On Red Hat/CentOS 7, and Amazon Linux 2:

     sudo rpm --import https://product-repository.ssh.com/info.fi-ssh.com-pubkey.asc
     sudo curl https://product-repository.ssh.com/ssh-products.repo -o /etc/yum.repos.d/ssh-products.repo
     sudo yum install firewalld
     sudo yum install PrivX-Extender

   • On Red Hat or Rocky Linux 8:

     sudo rpm --import https://product-repository.ssh.com/info.fi-ssh.com-pubkey.asc
     sudo curl https://product-repository.ssh.com/rhel8/ssh-products.repo -o /etc/yum.repos.d/ssh-products.repo
     sudo yum install firewalld
     sudo yum install PrivX-Extender

   • On Red Hat or Rocky Linux 9:

     sudo rpm --import https://product-repository.ssh.com/info.fi-ssh.com-pubkey.asc
     sudo curl https://product-repository.ssh.com/rhel9/ssh-products.repo -o /etc/yum.repos.d/ssh-products.repo
     sudo yum install firewalld
     sudo yum install PrivX-Extender

   • Alternatively, you may manually obtain the RPM. To do this, go to Settings→Deployment→Deploy PrivX VPC/VPN Extenders and click Download PrivX Extender. Then copy the rpm to the Extender host and install it with (replace /path/to/PrivX-Extender.*.rpm with the path to which you placed the Extender package):

     yum install /path/to/PrivX-Extender-*.rpm

2. Save the Extender configuration to the following path on the Extender host:
   /opt/privx/etc/extender-config.toml

3. Run postinstall to complete the setup:

   sudo /opt/privx/scripts/extender-postinstall.sh

The PrivX Extender is now set up. You may verify back on the Settings→Deployment→Deploy PrivX VPC/VPN Extenders page that the Status is Registered.

If the Extender failed to register to PrivX, you may find additional troubleshooting information from the Extender host at /var/log/privx/privx-extender.log

1. Configure the target host(s) for access via Extenders. For more information about accessing targets via Extenders, see the section called “Proxying Connections to Hosts”.

PrivX Carrier and Web Proxy Setup

This section provides setup instructions for PrivX Carriers and Web Proxies, which allow connecting to HTTP/HTTPS targets. The high-level workflow involves:

1. Create or download a web-access-gateway configuration.

2. Set up a PrivX Carrier.

3. Set up a PrivX Web Proxy.

To Create and Download Carrier/Web-Proxy Configurations

1. In the PrivX GUI navigate to Settings→Deployment→Deploy PrivX web-access gateways.

2. Obtain a web-access-gateway configuration. Either:

   • Create a new configuration, or
   • Download an existing configuration.

   You can create and download Extender configurations via the PrivX GUI at Administration→Deployment→Deploy PrivX web-access gateways.

1. Download the configurations (required later for setting up Carriers and Web Proxies). To do this, click next to your configuration, then click Download Carrier Config and Download Proxy Config.

PrivX-Agent Setup

This section provides instructions for installing PrivX agents, which allow PrivX users to connect using SSH native clients.

Unix setup

To set up native clients against PrivX for a user on a Unix workstation:

1. Obtain the PrivX-agent software, available from Get PrivX software.
   Save the Agents.zip package to the workstation.

2. Extract and install the PrivX agents to the workstation. For example (replace Agents.zip with the path to the agent-software package):

   unzip -j Agents.zip linux-amd64/privx-* -d /usr/local/bin/

The example command installs the PrivX agent, the agent utility, and the agent proxy to:
/usr/local/bin/privx-agent-unix
/usr/local/bin/privx-agent-ctl
/usr/local/bin/privx-nc
The following steps assume the PrivX agent and the agent utility to be in these locations.

1. Enable PrivX agent to start automatically when the user logs into the workstation. You can do this by appending the following to the users' .profile file:

# Start PrivX Agent unless there is already an ssh-agent running                                                          
START_PRIVX_AGENT="yes"                                                                                                   
PRIVX_AGENT_UNIX="/usr/local/bin/privx-agent-unix"                                                                        
if [ -n "$START_PRIVX_AGENT" ] && [ -z "$SSH_AUTH_SOCK" ] && \
   [ -x "$PRIVX_AGENT_UNIX" ]; then                             
    PRIVX_AGENT_DIR=`mktemp -d /tmp/ssh-XXXXXXXX 2>/dev/null || \
    mktemp -d -t 'mytmpdir'`                                                     
    export PRIVX_AUTH_SOCK="$PRIVX_AGENT_DIR/agent.$$"                                                                                         
    export PRIVX_AGENT_PROXY="$PRIVX_AGENT_DIR/proxy.$$"                                                                                       
    setsid nohup $PRIVX_AGENT_UNIX -a $PRIVX_AUTH_SOCK -x $PRIVX_AGENT_PROXY \
    -config $HOME/.privx/agent.json > /dev/null 2>&1 &                       
    export PRIVX_AGENT_PID=$!                                                                                                                  
    export SSH_AUTH_SOCK="$PRIVX_AUTH_SOCK"                                                                                                    
    export SSH_AGENT_PID="$PRIVX_AGENT_PID"                                                                                                    
    trap 'test -n "$SSH_AGENT_PID" && kill $SSH_AGENT_PID' 0                                                                                   
fi

1. Add PrivX servers to the agent. To do this, log in to the workstation as the user who will be using native clients (in order to start the agent), then run the following (replace https://privx.example.com with the address of your PrivX server):

   privx-agent-ctl server probe https://privx.example.com

   Unless the PrivX server certificate is trusted on the workstation, you will be presented with additional information, such as the SHA checksums of the certificate.

Would you like to add this server to trusted servers? Y/N:

You may ensure that these match to the checksums of the PrivX server certificate, which you can obtain by running the following on the PrivX server:

openssl x509 -noout -fingerprint -sha1 -in /etc/nginx/ssl/nginx.crt
openssl x509 -noout -fingerprint -sha256 -in /etc/nginx/ssl/nginx.crt

Once you have confirmed the server identity, enter Y to add the PrivX server.

1. You may verify setup by running:

privx-agent-ctl status

PrivX SSH Agent Status
  PrivX Server          https://privx.example.com
  Login status          logged out

MacOS setup

To set up native clients against PrivX for a user on a MacOS workstation:

1. Obtain the PrivX-agent software, available from Get PrivX software.
   Save the Agents.zip package to the workstation.

2. Extract and install the PrivX agents to the workstation. For example (replace Agents.zip with the path to the agent-software package):

unzip Agents.zip darwin-amd64/*
cp darwin-amd64/privx-agent-unix /usr/local/bin/
cp darwin-amd64/privx-agent-ctl /usr/local/bin/
cp darwin-amd64/privx-agent-start.sh /usr/local/bin/
cp darwin-amd64/privx-nc /usr/local/bin/

The example commands install the PrivX agent, the agent utility, the agent-startup script, and the agent proxy to:
/usr/local/bin/privx-agent-unix
/usr/local/bin/privx-agent-ctl
/usr/local/bin/privx-agent-start.sh
/usr/local/bin/privx-nc
The following steps assume the PrivX agent, the agent utility, and the agent-startup script to be in these locations.

1. Enable PrivX agent to start automatically when the user logs into the workstation. To do this, first install the agent launcher with:

cp darwin-amd64/com.privxagent.plist ~/Library/LaunchAgents/
launchctl load -w ~/Library/LaunchAgents/com.privxagent.plist
launchctl start ~/Library/LaunchAgents/com.privxagent.plist

Also append the following to the users' .bash_profile file:

# Register SSH_AUTH_SOCK & SSH_AGENT_PID to local environment
# if started by Launchd
if sock=$(launchctl getenv SSH_AUTH_SOCK); then
    export SSH_AUTH_SOCK=$sock
fi

if pid=$(launchctl getenv SSH_AGENT_PID); then
    export SSH_AGENT_PID=$pid
fi

Alternatively, users may manually start the PrivX agent with:

./privx-agent-unix bash

1. Add PrivX servers to the agent. To do this, log in to the workstation as the user who will be using native clients (in order to start the agent), then run the following (replace https://privx.example.com with the address of your PrivX server):

   privx-agent-ctl server probe https://privx.example.com

Unless the PrivX server certificate is trusted on the workstation, you will be presented with additional information, such as the SHA checksums of the certificate.

Windows setup

To set up native clients against PrivX for a user on a Windows workstation:

1. Ensure that the native clients on the workstation are in the system PATH.

2. Obtain the PrivX-agent software, available from Get PrivX software.
   Save the Agents.zip package to the workstation.

3. Extract the PrivX agents to the workstation. Navigate to the extracted folder, and in its windows-386 folder, run the privx-agent-windows.msi file to install the PrivX agent.

4. Start the PrivX agent in Start Menu→SSH Communications Security→PrivX Windows Agent.

1. Configure the agent to connect to PrivX: In the system tray, right click the PrivX icon and then select Settings.

• Enter the PrivX server URL. To verify the connection, click Test.

• You may verify the PrivX-server certificate:

  • Click View to open the Certificate Properties.
  • Check the certificate details. You do not need to install the certificate to the system.

• Click OK to save your settings.

PrivX-Router Setup

A PrivX Router is Linux iptables-based component, required for accessing network targets. PrivX Routers are controlled by PrivX and must be placed on the path between the VPN server and the protected targets.

Setting up a PrivX Router involves the following:

• Installing and configuring PrivX-Router software on the Router machine.
• Registering the Router machine in PrivX.

The machine on which you set up PrivX Router must satisfy the following:

To set up the PrivX Router, download PrivX IPtables Router and follow the instructions in the README file.

After PrivX Router is configured you may set up network targets via this Router, as described in Network Connections.

UEBA-Server Setup

UEBA servers allow PrivX to use machine learning to detect potentially anomalous connections. PrivX deployments support up to one UEBA server.

To set up a UEBA server:

1. Ensure that your machine satisfies the requirements at User and Entity Behavioural Analytics (UEBA). Particularly, note that the default Docker version included with some OS distributions may need to be upgraded to support UEBA.

2. Provide the UEBA-server details via the PrivX GUI: At Administration→Deployment→User Behavior Analytics, click Edit and provide at least the UEBA-server address and TLS trust anchor.

Then on the same page, obtain the UEBA startup script by clicking Download UEBA Server Configuration.

1. Gain root terminal access to the UEBA-server machine. Copy the UEBA startup script to this machine.

2. Install UEBA-server software with:

   sudo chmod u+x ueba-startup.sh
   sudo ./ueba-startup.sh ueba-tls.crt ueba-tls.key

   In the previous commands, replace example values as follows:

   • ueba-startup.sh - path to the UEBA startup script
   • ueba-tls.crt - path to the UEBA-server TLS certificate
   • ueba-tls.key - path to the UEBA-server TLS key

   After successful setup you may verify the UEBA-server status on the PrivX GUI Home page, under Service Status.

Upgrading PrivX deployment

This section provides instructions for upgrading your PrivX deployment.

Single-Server-Deployment Upgrade

To upgrade the PrivX server, gain root-terminal access to your PrivX server and run:

yum install PrivX

The system fetches and sets up the latest PrivX package. Upgrade is complete once the command completes.

If you haven't set up the PrivX product repository, obtain the latest version from available from Get PrivX software and run:

yum install PrivX-*.x86_64.rpm

High-availability deployment upgrade

For instructions about upgrading high-availability deployments, see PrivX high availability deployment.

Upgrading Optional Components

PrivX Extenders, Carriers, and Web Proxies can be upgraded after PrivX-server and database upgrade. The typical workflow for upgrading any of these components is:

1. Install the latest software package.
2. Run postinstall to complete setup.

The specific steps for each optional component are provided in the following subsections.

Upgrading PrivX Extenders

To upgrade PrivX Extenders, run these steps on all your Extender machines:

1. Install the latest Extender package in either of the following ways:

• If the PrivX repository is enabled on the machine. Install the package with:

yum install PrivX-Extender

• Without the PrivX repository, go to Settings→Deployment→Deploy PrivX VPC/VPN Extenders and click Download PrivX Extender:
  Then copy the rpm to the Extender host and install it with (replace `/path/to/PrivX-Extender..rpm`* with the path to which you placed the Extender package):

yum install /path/to/PrivX-Extender-*.rpm

1. You may need manually merge extender-config.toml changes
2. Run postinstall to complete the upgrade:

/opt/privx/scripts/extender-postinstall.sh

Upgrading PrivX Carriers and PrivX Web Proxies

PrivX Carriers and Web Proxies together enable web connections, and should be upgraded together.

To upgrade PrivX Carriers:

1. Install the latest Carrier package in either of the following ways:

• If the PrivX repository is enabled on the machine. Install the package with:

yum install PrivX-Carrier

• Without the PrivX repository, go to Settings→Deployment→Deploy PrivX web access gateways and click Download PrivX Web Access Gateway Components:
  Then copy the rpm to the Carrier host and install it with (replace `/path/to/PrivX-Carrier..rpm`* with the path to which you placed the Carrier package):

yum install /path/to/PrivX-Carrier-*.rpm

1. You may need manually merge carrier-config.toml changes
2. Run postinstall to complete the upgrade:

/opt/privx/scripts/carrier-postinstall.sh

To upgrade PrivX Web Proxies:

1. Install the latest Web-Proxy package in either of the following ways:

• If the PrivX repository is enabled on the machine. Install the package with:

yum install PrivX-Web-Proxy
