ip conflicting
Posted: Tue Feb 26, 2008 3:18 am
Salam O Alykum.
i have 4 internet cafes, 40 clients each cafe, that have ip conflicting problem,
i have checked with dynamic as well as manual ip setting, same problem,
now i am assigning 2 gateway to my client, but still same.
some of client computer shows the message of "ip conflict", At the time of appearing of this massage,i use to checked from different softwares,(netcut, ipscanner etc) that 2nd ip also assigned that pc, and the ip is shown of my server ip,
like in net netcut during scanning i can see like
192.168.0.20 -- 00:22:22:22:33:20 -- pc20
192.168.0.21 -- 00:22:22:22:33:2c -- pc21
192.168.0.22|192.168.0.1 -- 00:22:22:22:33:2a -- pc22
192.168.0.23 -- 00:22:22:22:33:dd -- pc23
my server is on ubuntu 7.04 server, Using squid, iptables, shaper and dhcp.
on the infected computer consol when i type ipconfig /all, so there is not ip like 192.168.0.1
several of my clients assigning my linux ip (which is the gateway for clients) #to their self,
is it a virus??
i need help for this solution.
its confirm that there is no ip confliction in real, means no misconfiguration in real. mean to say i did not have taken any mistake to put 2 ips in my network,
my dhcpd.conf is here
---------------
# A slightly different configuration for an internal subnet.
subnet 192.168.2.0 netmask 255.255.255.0 {
range 192.168.2.40 192.168.2.200;
option domain-name-servers 192.168.2.1, 212.118.133.101;
# option domain-name "internal.example.org";
option routers 192.168.2.1;
# option broadcast-address 10.5.5.31;
default-lease-time 6000;
max-lease-time 72000;
}
