Asus G73SW Drivers

Asus G73SW Drivers



I came across talking to same users(/etc/passwd)in the local server. The same could be used to even talk to the users remotely.

To talk to the user who is logged in more than once, use ttyname to indicate the appropriate terminal name.Once communication has been established, the two parties may type simultaneously.

Lets see how can we configuire this.

1. Verify the package is installed, if not install by yum or rpm.
[root@server ~]# rpm -qa | grep talk
talk-0.17-29.2.2
talk-server-0.17-29.2.2
[root@server ~]#

2. Change Disable=no in talk file.
[root@server ~]# vi /etc/xinetd.d/talk
# default: off
# description: The talk server accepts talk requests for chatting with users
#       on other systems.
service talk
{
        flags                   = IPv4
        disable                 = no
        socket_type             = dgram
        wait                    = yes
        user                    = nobody
        group                   = tty
        server                  = /usr/sbin/in.talkd
}

3. Make sure both talk and ntalk are on
[root@server ~]# chkconfig --list | grep talk
        ntalk:          on
        talk:            on

4. Restart xinetd service to take effect.
[root@server ~]# service xinetd restart
Stopping xinetd:                                           [  OK  ]
Starting xinetd:                                            [  OK  ]

Case 1:
I shall communicate to different user(login names)on the same server. 

[root@server ~]# grep "^root" /etc/passwd
root:x:0:0:root:/root:/bin/bash

[root@server ~]# grep "sysadm" /etc/passwd
sysadm:x:854:855::/home/sysadm:/bin/bash







Case 2:
Talk to a user who is logged in more than once.Here, you need to communicate with their terminal name.

[root@server ~]# tty
/dev/pts/1

[sysadm@server ~]$ tty
/dev/pts/3
