Troubleshooting
Problem
Remote logins to WPAR are not allowed due to console and ptys allocation
Symptom
If using telnet, the following symptoms are shown:
- WPAR connection fails telnetd: All network ports in use
- login: root's Password:
/dev/pts/66: Password read timed out -- possible noise on port
If using ssh, the following symptoms are shown:
- PRNG is not seeded
- Server refused to allocate pty
Cause
- WPAR console is not set.
- Random device driver is not loaded
- PTY is not configured.
