# 5.1.2 Ensure rsh server is not enabled (Scored)

## Profile Applicability

- Level 1

## Description

The Berkeley `rsh-server` (`rsh`, `rlogin`, `rcp`) package contains legacy services that exchange credentials in clear-text.

## Rationale

These legacy services contain numerous security exposures and have been replaced with the more secure SSH package.

## Audit Procedure

### Using Command Line

Ensure the `rsh` services are not enabled:

```bash
grep ^shell /etc/inetd.conf
grep ^login /etc/inetd.conf
grep ^exec /etc/inetd.conf
```

## Expected Result

No results should be returned.

## Remediation

### Using Command Line

Remove or comment out any `shell`, `login`, or `exec` lines in `/etc/inetd.conf`:

```bash
sed -i 's/^shell/#shell/' /etc/inetd.conf
sed -i 's/^login/#login/' /etc/inetd.conf
sed -i 's/^exec/#exec/' /etc/inetd.conf
```

## Default Value

Not enabled by default on Ubuntu 12.04 LTS Server.
