Pre-Installation / Upgrade Backups

The installation process overwrites the current files (exception: the configuration files are kept), effectively removing your modifications. Backing up these files will optimize the time it takes you to get up and running after installing or upgrading.

Note

If you are upgrading an installation of UDMG from any release prior to 1.3.0.0, you must uninstall the older version before installing the new version.
The binaries, services, configuration parameters, and environment variables have changed and this does not allow for a standard upgrade.

Category	Prior releases	Release 1.3
UDMG Admin UI assets	C:\UDMG\nginx\mft	C:\UDMG\nginx\udmg
Environment variables	WAARP_GATEWAY_ADDRESS MFT_AUTH_PROXY_CONFIG MFT_AGENT_PROXY_CONFIG	UDMG_SERVER_ADDRESS UDMG_AUTH_PROXY_CONFIG UDMG_AGENT_PROXY_CONFIG

It may be required to modify the work and data directories ownership or access rights and to update UDMG Server transfer rules to use new paths.

The configuration files must be reviewed and compared between the old and new versions.

Special attention is required for the AESpassphrase parameter for UDMG Server. It must be the path for the file that was used by the previous release and must be accessible by the new service user. It is recommended to set an absolute path in the configuration file.

Upgrading UDMG Server

The UDMG release version is stored in the database to ensure the data structure is compatbile with the version of the UDMG components.

After upgrading the component binaries and before starting the UDMG server it is required to perform the release migration step.

The udmg-server "migrate" command handles the necessay database updates and the setting of the internal version.

C:\UDMG\UDMG Server>udmg-server migrate /?
Usage:
  udmg-server [OPTIONS] migrate [migrate-OPTIONS] [version]

Help Options:
  /?                Show this help message
  /h, /help         Show this help message

[migrate command options]
      /c, /config:  The configuration file to use
      /d, /dry-run  Simulate the migration but does not commit the changes
      /l, /list     List Migrations
      /f, /file:    Writes the migration commands into a file instead of sending them to the database
      /v, /verbose  Show verbose debug information. Can be repeated to increase verbosity

[migrate command arguments]
  version:           The version to which the database should be migrated

The configuration file is the one that will be used for the server mode, with the parameter for accessing the target database.

To get the list of supported target version, use the list parameter. The last version is the release version of the udmg-server.

C:\UDMG\UDMG Server>udmg-server migrate /c "C:\UDMG\UDMG Server\server.ini" /list 
0.7.1
0.7.1-sb.1
0.7.1-sb.2
0.7.1-sb.3
1.3.0

It is recommended to set the verbose parameter (3 times) to follow the progress.

C:\UDMG\UDMG Server>udmg-server migrate /c "C:\UDMG\UDMG Server\server.ini" /v /v /v 1.3.0.0

UDMG Authentication Proxy

Create a directory C:\UDMG\UDMG Auth Proxy
Install the binaries as udmg-auth-proxy.exe
Create the configuration file C:\UDMG\UDMG Auth Proxy\config.toml with the following parameters:

# Proxy Configuration
[proxy]
# Port, default "5000"
port = "5000"
# Network interface, default "0.0.0.0"
inet = "127.0.0.1"
# Enable recover on panic, default true, should be true for production environment
recover = true
# Enable Cross-Origin Resource Sharing (CORS), should be true for production environment
cors = true # CORS: List of origins that may access the resource. Optional. Default value "*" # domain = "*"
# Enable Request Track ID, default true
tracker = true
# Enable Request Logger, default true
logger = true
# Rate Limit IP Request over 1 second, default 0 (unlimited)
limit = 0
# Enable the Prometheus Metric Endpoint '/metric', default false
metrics = false # Enable CSRF token csrf = false# Service 'local' with direct authentication on the UDMG Server
[service.local]
# UDMG Server Listen Protocol
protocol = "http"[[service.local.targets]]
# UDMG Server Hostname or IP
hostname = "localhost"
# UDMG Server Port
port = 18080

Please refer to Authentication Methods for the LDAP and SSO authentication options.

UDMG Agent Proxy

Create a directory C:\UDMG\UDMG Agent
Install the binaries as udmg-agent-proxy-client.exe and udmg-agent-proxy-server.exe

Agent Proxy Server Configuration

Generate a SSH Key for the service.
For example with the ssh-keygen tool that is provided by Windows OpenSSH tools (Key-based authentication in OpenSSH for Windows), or by 3PP packages like Copssh - OpenSSH for Windows or Portable Git for Windows

# ssh-keygen -t rsa -q -N "" -f "C:\UDMG\UDMG Agent\agent_key"
# ssh-keygen -t rsa -q -N "" -f "C:\UDMG\UDMG Agent\client_key"

If OpenSSH is not installed or not available, the PuTTY tool can be used instead.

Use PuTTYgen to generate a key pair for the agent, more detailled instructions can be found here: Using public keys for SSH authentication

After generating the key, export it with OpenSSH format:

Create a configuration file as C:\UDMG\UDMG Agent\agent\agent.toml

[agent]
# Listen IP Address
hostname = "0.0.0.0"
# Listen Port
port = "2222"
# SSH Priv Key
ssh_key = "C:\UDMG\UDMG Agent\agent_key"
# SSH Public Key
ssh_key_pub = "C:\UDMG\UDMG Agent\agent_key.pub"

# Service User
username = "mft"
# Service Password
password = "61ee8b5601a84d5154387578466c8998848ba089"

The password key will be used for the client authentication.

Agent Proxy Client Configuration

Create a configuration file as C:\UDMG\UDMG Agent\client\client.toml

[client]
# UDMG Agent Proxy Hostname or IP
hostname = "localhost"
# UDMG Agent Proxy Listen Port
port = "2222"

# UDMG Agent Service User and password
username = "mft"
password = "61ee8b5601a84d5154387578466c8998848ba089"

# Default TTL to Connection Retry
ttl="5s"

# UDMG Agent Client Admin API
[client.api]
# Listen Port
port="2280"

# UDMG Server
[gateway]
# UDMG Server Hostname or IP
hostname = "localhost"
# UDMG Server Port
port = "18080"
# UDMG Server Username/Password
username = "admin"
password = "admin_password"

The password key will be used for the client authentication.
