tcp port always closed in inetd
sco unix 5.0.x, several weeks ago, I add a telnet-like service in inetd.conf, it runs well for 100 network terminals.
But nowdays, the terminals can connect to server successfully after booting machine, but several hours later, can not connect. "netstat -p tcp -a" can NOT find the port in LISTENING state. If I "kill -1 pid-of-inetd" to refresh the inetd process, the port listens again and terminals can connect too. But hours later problem occurs again.
why and how to solve it?
Put the service entry in inetd.conf to begining of file?

inetconv
inetconv(1M) System Administration Commands inetconv(1M)
NAME
inetconv - convert inetd.conf entries into smf service manifests, import them into smf repository
SYNOPSIS
inetconv -?
inetconv [-f] [-n] [-i srcfile] [-o destdir]
inetconv -e [-n] [-i srcfile]
DESCRIPTION
The inetconv utility converts a file containing records of inetd.conf(4) into smf(5) service manifests, and then import those manifests
into the smf repository. Once the inetd.conf file has been converted, the only way to change aspects of an inet service is to use the
inetadm(1M) utility.
There is a one-to-one correspondence between a service line in the input file and the manifest generated. By default, the manifests are
named using the following template:
<svcname>-<proto>.xml
The <svcname> token is replaced by the service's name and the <proto> token by the service's protocol. Any slash (/) characters that exist
in the source line for the service name or protocol are replaced with underscores (_).
The service line is recorded as a property of the converted service.
During the conversion process, if a service line is found to be malformed or to be for an internal inetd service, no manifest is generated
and that service line is skipped.
The input file is left untouched by the conversion process.
OPTIONS
The following options are supported:
-?
Display a usage message.
-e
Enable smf services which are listed in the input file.
-f
If a service manifest of the same name as the one to be generated is found in the destination directory, inetconv will overwrite that
manifest if this option is specified. Otherwise, an error message is generated and the conversion of that service is not performed.
-i srcfile
Permits the specification of an alternate input file srcfile. If this option is not specified, then the inetd.conf(4) file is used as
input.
-n
Turns off the auto-import of the manifests generated during the conversion process. Later, if you want to import a generated manifest
into the smf(5) repository, you can do so through the use of the svccfg(1M) utility.
If the -e option is specified, the -n option only displays the smf services that would be enabled.
-o
Permits the specification of an alternate destination directory destdir for the generated manifests. If this option is not specified,
then the manifests are placed in /var/svc/manifest/network/rpc, if the service is a RPC service, or /var/svc/manifest/network other-
wise.
EXAMPLES
Example 1: Generating smf Manifests from inetd.conf
The following command generates smf(5) manifests from inetd.conf(4) and places them in /var/tmp, overwriting any preexisting manifests of
the same name, and then imports them into the smf repository.
# inetconv -f -o /var/tmp
100232/10 -> /var/tmp/100232_10-rpc_udp.xml
Importing 100232_10-rpc_udp.xml ...Done
telnet -> /var/tmp/telnet-tcp6.xml
Importing telnet-tcp6.xml ...Done
Example 2: Generating Manifests from an Alternate Input File
The following command specifies a different input file and does not load the resulting manifests into the smf repository.
# inetconv -n -i /export/test/inet.svcs -o /var/tmp
100232/10 -> /var/tmp/100232_10-rpc_udp.xml
telnet -> /var/tmp/telnet-tcp6.xml
EXIT STATUS
The following exit values are returned:
0
Operation completed successfully (no errors).
1
Invalid options specified.
2
One or more service lines are malformed, and thus no manifest(s) were generated for them.
3
An error occurred importing one or more of the generated manifests.
4
A system error occurred.
FILES
/var/svc/manifest/network/{rpc}/<svcname>-<proto>.xml
default output manifest file name
