Re: Detailed Problem:Unable to Connect to Internet

[rebel indian <rebel_student@xxxxxxxxx>]

Hi folks:

 

I don have /sbin/dhclient-script
instead I have /sbin/dhcpd
when I run it

 

[root@xxxxxx root]# /sbin/dhcpcd
****  /sbin/dhcpcd: already running
****  /sbin/dhcpcd: if not then delete /etc/dhcpc/dhcpcd-eth0.pid file

 

$vim /etc/resolv.conf

nameserver 159.149.70.1
search crema.unimi.it

 

 

$vim /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0
ONBOOT=yes
BOOTPROTO=dhcp
PEERDNS=yes
TYPE=Ethernet
USERCTL=no

There is nothing in dhcp.leases file

$vim /var/lib/dhcp/dhcpd.leases

$vim /etc/dhcpc/dhcpcd-eth0.info

IPADDR=159.149.71.28
NETMASK=255.255.255.128

I don't know what your specific problem is but....

Make sure /etc/sysconfig/network-scripts/ifcfg-eth0 sez something like:

DEVICE=eth0
BOOTPROTO=dhcp
ONBOOT=yes
DHCP_HOSTNAME=mupplesnarf
PEERDNS=yes
TYPE=Ethernet

Then restart the networking:

$ sudo service network restart

Check /etc/resolv.conf for DNS servers. If the first line is not someothng
like: "; generated by /sbin/dhclient-script" check the permissions. The
should be 644.

Check /var/lib/dhcp/dhclient-eth0.leases to see want information was sent with
your lease. The DNS sever _should_ be in there.

option domain-name-servers 192.168.124.10,192.168.124.20;

It should also tell you where you got the lease from:

option dhcp-server-identifier 192.168.124.10;

If NOTA helps, bring the networking down

$ sudo service network stop

then try running dhclient from the command line with debuging.

$ sudo dhclient -d eth0
