how to give Telnet access

Hello,

I have recently taken over administration of a Sco Unixware server (Version 7.1.4), but have no previous experience with Unix.

I now have the following problem: Most computers on the network are unable to Telnet to the Unix server but some PCs with privileged users can, which is fine. I now need to allow Telnet access to the server for another PC but I can't find where this has been configured.

I have checked the /etc/inet/hosts.allow and hosts.deny files but these files appear to have default values that are all commented out. I have checked for access-lists on the Layer 3 switch that connects the host to the server but there are no access lists configured. All hosts on the network can ping the server and access the server through SSH so there are no communication issues between host and server. When the host that I am trying to grant access tries to Telnet to the server from a command prompt in Windows the CMD window is just blank with a flashing cursor which then times out and returns to the usual command prompt.

Does anybody know where access rules for Telnet might be configured on this Sco server?

Many thanks,
Nick

wnnaccess(1M)						  System Administration Commands					     wnnaccess(1M)

NAME
wnnaccess - Access control over Wnn6 Kana-Kanji conversion server/dictionary lookup server SYNOPSIS
/usr/sbin/wnnaccess [-D jserver_name] [-ds wnnds_name] [-L LANG_name] [ -| + [hostname | username] ] DESCRIPTION
wnnaccess adds or deletes hosts and users, obtains the current access control information, enables or disables access control for access permission retained by the Wnn6 Kana-Kanji conversion server/dictionary lookup server. OPTIONS
The following options are available. -D jserver_name Specifies the Wnn6 Kana-Kanji conversion server (jserver) to work on. If this option is omitted, wnnaccess refers to the serverdefs file and determines the Kana-Kanji conversion server to work on. The Kana-Kanji conversion server must be specified in the following format. hostname Kana-Kanji conversion server that uses the well-known port number(22273) on host hostname hostname:no Kana-Kanji conversion server that uses port number of " the well-known port number plus no" on host host- name hostname/port_noKana-Kanji conversion server that uses port_no as port number on host hostname -ds wnnds_name Specifies the Wnn6 dictionary lookup server (wnnds) to work on. The dictionary lookup server must be specified in the following format. hostname Dictionary lookup server that uses the well-known port number(26208) on host hostname hostname:no Dictionary lookup server that uses port number of "the well-known port number plus no" on host hostname hostname/port_noDictionary lookup server that uses port_no as port number on host hostname -L LANG_name Specifies the language. The language is used to refer to the serverdefs file and determine the server to connect. Specify ja for the Solaris releases (Japanese version). If no options are specified, wnnaccess writes the current access control information. The first line shows the current status of access control enabled or disabled. The second and following lines show hosts and users that are given access rights as in any of the following formats: host-name All users can access from this host. host-name: No users can access from this host. host-name:user-name,user-name,..Only users shown in the list can access from this host. @user-name This user can access from any host. Specifying - option only enables access control. Specifying + option only disables access control. If access control is disabled, no restriction is imposed on connection to the server. If + option and hostname| username are specified, the host or user will be added to the access control. If - option and hostname| username are specified, the host or user will be deleted from the access control. The format of hostname| username is the same as in displaying the current access control information. If neither - nor + option is specified, the behavior will be the same as in specifying + option.
