## adding users

> see the [makeuser](https://tildegit.org/team/makeuser) script's documentation

the signup page ([source](
https://tildegit.org/team/site/src/branch/master/signup/signup-handler.php))
writes `makeuser` commands into `/var/signups`.

once you've looked through signups and removed spam (by just commenting that
line in the signups file), you can run

    sh /var/signups

and enter your sudo password to approve all pending requests

## services

for hosted services that formerly lived in `/home/services`, see `/opt`.

other projects that are installed with a `make install` type of install
can now be found in `/usr/local/src`.

as needed, feel free to git pull and make install. for hosted services
like tilde.news and pad.tildeverse.org, be sure to check release notes,
fetch from upstream, and rebase any commit sets we keep on top.

## backups

tilde.team uses [borg](https://borgbackup.readthedocs.io/en/stable/) (via 
[borgmatic](https://torsion.org/borgmatic)) for backups and is configured 
to save 7 daily backups, 4 weekly backups, 6 monthly, and 1 yearly backup.
backups run once daily during the night.

to see a list of the backups:

    sudo borgmatic list

to see general backup stats:

    sudo borgmatic info

to restore a backup:

    sudo borgmatic extract --archive <archive name> --progress --path /path/to/restore

we keep backups of:
* `/home`
* `/etc`
* mysql and postgres databases (dumped before each backup run)
* [nextcloud](https://cloud.tilde.team/) data
* [tildegit](https://tildegit.org) database and repos
* `/var/spool/cron` - your crontabs
* `/tilde` - user-submitted scripts
* [mailman3](https://lists.tildeverse.org) list and archive data


## bypassing resource limits

(by [~khuxkm](https://khuxkm.tilde.team/))

So occasionally, when you're working with the services user, you'll run into 
"error: fork: retry: Resource temporarily unavailable" errors.

Here's how to fix it:

    07:11 <~khuxkm>  so this is seriously dumb
    07:11 <~khuxkm>  so how you fix limits is
    07:12 <~khuxkm>  sudo -iu services
    07:12 <~khuxkm>  use ps -aux to find the bash process ("-bash")
    07:12 <~khuxkm>  then `sudo prlimit --pid <pid> --nproc 1000000:100000000`
    07:12 <~khuxkm>  then do what you need to do
    07:12 <~khuxkm>  then exit the bash session


## runaway processes

if a user consistently uses a lot of resources, send them a note via email
to request that they mind their usage levels. if they fail to respond within
a day or two, feel free to kill the process by pid or with `killall`. if they
resume using excessive resources and haven't responded to communications, then
feel free to lock them out by changing their shell to `/usr/sbin/nologin`.

    sudo chsh -s /usr/sbin/nologin <username>

don't forget to kill their existing session with:

    sudo loginctl terminate-user <username>
