Network client installer

install_openvpn_client_anolis8.sh

Uses dnf, EPEL and systemd. Without a complete config/login pair it prepares the directory and exits before configuring the service. With files present it copies or reuses them, normalizes CRLF, sets mode 600 and restarts the selected client instance.

One-liner

curl -fL 'https://www.helper.sh/install_openvpn_client_anolis8.sh' -o './install_openvpn_client_anolis8.sh'

This command downloads the bundled file only; it does not run it. Inspect the saved source and compare its version before deciding whether to execute it.

Save checksum file

Save the script and checksum in the same directory. On Linux with GNU Coreutils, the command below checks the saved bytes only; it does not run the script. Keep the original filename for this command.

Selected file SHA-256

The checksum and script come from the same site, not an independent signature. A match does not prove safety, authenticity of upstream dependencies, or suitability for your host. Mutable remote dependencies need separate review.

Read validation and limitations

Requirements

Anolis OS 8; root; systemd; reachable dnf/EPEL repositories.
A reviewed client.conf and login.txt pair is required to configure a tunnel.

Best for

Maintain an existing distribution-specific username/password client.
Stage package installation separately when client files are not yet available.

Highlights

Accepts --config-dir, --config-name, --source-conf, --source-login, --source-dns-helper and --no-dns.
Default destination: /etc/openvpn/client/client.conf and login.txt; replacement copies receive timestamped backups.
Default DNS helper can change NetworkManager or /etc/resolv.conf. --no-dns skips helper/hook work; it does not undo pre-existing hooks.

Recommended procedure

Download and inspect the installer and any supplied DNS helper before authorizing root execution.
Read-only checks: systemctl status openvpn-client@client --no-pager; journalctl -u openvpn-client@client -n 100 --no-pager; ip route; cat /etc/resolv.conf. Adjust the instance name if changed.
An active service is only a process check. Verify the intended private route and resolver separately; inspect logs before retrying. Do not share raw credentials or logs.

Safety notes

No dry-run or automatic rollback. Service restarts and resolver changes may interrupt remote access.
Protect login.txt and its backups. Review endpoint, certificates, pushed routes and helper source before use.
Anolis 8 package availability and resolver ownership must be checked locally; no live host was tested for this review.

OpenVPN: distinguish tunnel, route and DNS failures

Choose the distribution-specific client and inspect resolver ownership before changing DNS hooks.
