rlogin/telnet difficulties: "Connection closed by foreign host" |
| Ref. No. |

| Issue |
The following message gets displayed when we try to telnet to a QNX 4 TCP/IP server:
Trying <ip_address>...
Connected to <hostname>.
Escape character is '^]'.
telnetd: :No such file or directory
.
Connection closed by foreign host.

| Solution |
The following daemons require that pseudo-tty support be available:
rlogind - remote login
telnetd - remote terminal session
To have the host provide remote login or terminal sessions, make sure that the list of boot processes for the host (e.g. /etc/config/sysinit.<node>) includes the pseudo tty driver:
Dev.pty &
If Dev.pty is already running and the above error message is still seen, the number of available pseudo tty devices must be increased. This can be done with the '-n<num>' option to Dev.pty.
For more information, please see the Dev.pty section in the QNX 4 Utilities Reference:
