# pglistener-update(1)

postgres listener.

## NAME

**pglistener-update** - postgres listener.

## DESCRIPTION

**pglistener-update is a daemon that generates files from Postgres database.**

**It is a tool that listens for notifies from a Postgres database** **and then calls out to a number of hooks which do everything from updating** **the password database to updating accounts in RT.**

## USAGE

**Config and hooks live under:**

```
    /var/lib/pglistener
    /var/lib/pglistener/hooks
    /etc/pglistener
    /etc/pglistener/conf.d
```

**It is fine to restart postgres while pglistener is running.**

**If pglistener crashes for whatever reason, it can be restarted as a** **normal service.**

**Pglistener can in general be restarted at any time, it's quick to** **start and there are no interruptions to services or authentication.**

## SETTING UP

**Install a usable pglistener config in /etc/pglistener/pglistener.conf** **and should be mode 600, user pglistener.**

**Make symlinks for databases in /var/lib/misc:**

```
    cd /var/lib/misc
    ln -s ../pglistener/group.db
    ln -s ../pglistener/passwd.db
    ln -s ../pglistener/shadow.db
```

**If you have ssh keys for everybody on the host, add the following two lines to /etc/ssh/sshd\_config:**

```
    AuthorizedKeysFile /root/%u/.ssh/authorized_keys
    AuthorizedKeysFile2 /var/lib/misc/sshkeys/%u
```

**Make sure pam\_mkhomedir is set up, /etc/pam.d/common-session should contain:**

```
    session required pam_mkhomedir.so
```
