Secure Git Rebase over SSH Access Proxy

git rebase is precise. It rewrites commit history. When your repository lives behind an SSH access proxy, every connection, handshake, and packet matters. Latency can corrupt a rebase. Misconfigured keys can lock you out mid-sequence.

To run git rebase under SSH access proxy conditions, start with secure key management. Use ssh-agent to load keys and forward them across the proxy. This keeps credentials from leaking and ensures fast authentication. Configure your .ssh/config file with a ProxyCommand or ProxyJump directive that matches your proxy’s requirements. Accuracy here prevents broken streams during rebase operations.

Verify your remote URLs. They must use the git@host:path/repo.git format over SSH. HTTP endpoints often fail or add unwanted authentication prompts when routed through a strict proxy. Once the SSH tunnel is stable, fetch the latest changes:

git fetch origin

Check your branch state before rebasing:

git status
git log --oneline --graph --decorate

Run the rebase:

git rebase origin/main

If conflicts appear, solve them locally before pushing. Over SSH proxies, resolving conflicts remotely is slower and riskier. Use git rebase --continue after edits, and git rebase --abort if the operation cannot be salvaged.

Monitor the connection during the process. Packet loss in a proxy flow can leave the local repo in a half-rebased state. Keep logs with GIT_SSH_COMMAND="ssh -v" to diagnose issues before they halt the pipeline.

Once rebase completes, push changes back through the SSH proxy:

git push origin HEAD

This workflow keeps commit history clean, preserves repository integrity, and minimizes downtime.
