## MCP tool

`manitu_webhosting_web_sshuser_set`

### Description for the model

Changes an SSH user of a web hosting package of the manitu customer account this connection works in, by site_id and username from manitu_webhosting_web_sshuser_list. Only the fields given change. Keys: ssh_key_list REPLACES all keys - to add one, read the keys with manitu_webhosting_web_sshuser_get and send the old ones plus the new one; or ssh_keys_same_as copies another SSH user's keys. If the customer wrote lines on the server that would be lost (options like command= or from=), the call is refused with the conflict ssh_keys_would_be_lost and those lines - tell the customer, and only with his yes send it again with replace_all true. status inactive switches it off without deleting it and ends its open sessions; expires_at null removes the end. Refused with a conflict when the package cannot be changed now (not_configurable). Tell the customer what will change and ask for an explicit yes first.

### Arguments

- `site_id` (integer | string, required) - The site_id from manitu_webhosting_list - never guess one. (pattern `"^[1-9][0-9]*$"`; minimum `1`)
- `username` (string, required) - The user name of the SSH user (ssh<number>) from manitu_webhosting_web_sshuser_list - never guess one. (maxLength `32`; pattern `"^ssh[0-9]+$"`)
- `quota_mb` (integer | null) - Disk space in MB the files it owns may take, at most the package's; null or 0: no limit of its own. (minimum `0`)
- `status` (string) - active, or inactive to switch it off without deleting it. Default when created: active. (one of `"active"`, `"inactive"`)
- `expires_at` (string | null) - When the SSH user expires - it works up to the next midnight (Europe/Berlin) at or after the moment given, which the answer shows. Not in the past. From this moment on it can no longer be used (the moment itself is excluded); null: without end. (format `date-time`)
- `description` (string | null) - The customer's description, for his own overview - e.g. who uses it. Left out: unchanged (set) or none (create); null or empty: none. (maxLength `1024`)
- `ssh_key_list` (array of string) - The public keys that may log in as this SSH user - all of them: the list replaces the keys it has. Only one of ssh_key_list, ssh_keys_same_as. Each one public key, one line as in authorized_keys: "ssh-ed25519 AAAA... comment" (also ecdsa-sha2-nistp256/384/521, ssh-rsa from 2048 bits). No options in front of the key (command=, environment=, from= ...), no DSA. The public key only - never a private key. (minItems `1`; maxItems `50`)
- `ssh_keys_same_as` (string) - The user name of the SSH user (ssh<number>) from manitu_webhosting_web_sshuser_list - never guess one. (maxLength `32`; pattern `"^ssh[0-9]+$"`)
- `shell` (string) - bash (default when created), zsh, or git - git-shell: only git push/pull, no commands. (one of `"bash"`, `"zsh"`, `"git"`)
- `replace_all` (boolean) - true: replace the keys even if lines the customer wrote on the server are lost (after ssh_keys_would_be_lost, with the customer's yes). Default false.
