0 Log only LOG_CRIT messages.

1 Log only LOG_CRIT and LOG_ERR messages.

2 Log only LOG_CRIT, LOG_ERR, and LOG_WARNING messages.

3 Log all messages.

If it is omitted, the logging level is set to 1.

-nnode_name Specify the IP address of the terminal server or the port.

-pport_no Specify a DTC port number or, if the

-b option is omitted, the TCP port service

address that will be used by the software to access the port. If the value is omitted,

the value

23 (Telnet) is used by default.

In order to shutdown every

ocd running without restarting them, the following command can be exe-

cuted:

kill -15 ‘ps -e | grep ocd | awk ’{print $1}’‘

WARNINGS

In order to ensure that commands (such as ps) display the correct device ﬁle name (that is, the pseu-

donym), all pseudonyms should be placed into the directory

/dev/telnet. If pseudonyms are not

speciﬁed for placement in this directory, the correct display of device ﬁle names with many commands is

not guaranteed.

In addition, in order to ensure that commands (such as

w, passwd, finger, and

wall) work correctly,

each pseudonym must be unique in its ﬁrst 17 characters (including the directory preﬁx

/dev/telnet/). If pseudonyms are not unique in their ﬁrst 17 characters, the correct functioning of

many commands is not guaranteed.

Also, in order to reliably handle timing mark negotiations (and ensure that ﬁles printing on a printer

attached to a terminal server have been completely ﬂushed to that printer), the following line must be

added near the end of each printer interface script for printers attached to a terminal server:

stty exta <&1 2>/dev/null

The printer interface scripts reside in the directory /etc/lp/interface

. The line must be added just

prior to the ﬁnal ’exit’ command in each printer interface script.

If this line is not added as speciﬁed, the printing reliability of printers attached to a terminal server is not

guaranteed.
