DNS error,does not respond on ping.
hi,
I use RH Linux 9.0. To connect to the net my ISP has given me an application called crclient. i login to this application by ./crclient -u username & password. He has also given me the IP,Subnet,Default gateway,DNS1,DNS2 addresses. I have entered these data. Now I am able to ping the IP,subnet successfully. DNS doesn't respond. The same adresses work in my Windows 2K m/c. Am i missing out on any other configuration? Is there is a checklist I need to go through? thanks a ton, Jared |
post the O/P of
route -n and the contents of the file /etc/resolv.conf regards |

Please only post your questions in one forum.
Please give us the contents of the "/etc/resolv.conf" file. |
./etc/resolv.conf O/P
hi,
the contents of /etc/resolv.conf are ;generated by /sbin/dhclient-script nameserver 192.168.1.1 this address is different from all my known adresses. also please note that my connectivity is my m/c (RH 9.0 linux)----->LAN----->cablemodem------->ISP thanks, Jared |
in ur resolv.conf
enter this nameserver <ip of ur DNS sever> and see if it works and post what u get when u run this as root /sbin/route -n regards |
hi,
i edited the /etc/resolv.conf to show the nameserver as my DNS IP. It still does not respond on ping. Also /sbin/route -n shows as follows Destination Gateway Genmask Flags Metric Ref Use Interface 172.16.20.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0 127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo 0.0.0.0 172.16.20.1 0.0.0.0 UG 0 0 0 eth0 what do i do next? thanks, Jared |
what do u get for
traceroute linuxquestiuons.org and ping linuxquestiuons.org can u ping any ip of any domain?? regards |
tracreroute and ping
hi,
taceroute and ping don't respond to other domains.i get these messages traceroute:unknown host linuxquestions.org ping: unknown host linuxquestions.org these are working for my IP,gateway only.. thanks, Jared |
if u cannot ping any ip after ur gateway then it is not the problen of only DNS
but i think that software is not authenticating you regards |
authentication
hi,
I use the same application in windows to login and access the internet.it is working fine.. I am able to ping all the adresses in windows in which i don't have any problem.. there seems to be some problem with the configuration of these addresses in RH Linux which I don't have a clue on.. I have even checked by disabling the iptables. Even that does not work.. Can you think of anything else to try out? Also when I try the set preferences of the client by ./crclient -s it asks me password remember yes or no.. and then the server ip in dotted format. When i give that it says "segmentation fault". Is this anything related? I have configured eth0 with the addresses I have already. thanks, Jared |
that what i am saying that u have some problems with ur software
contact ur ISP for that since we do not have that kind of setup so we cannot comment on that regards |
troubleshooting
hi,
Unfortunately my ISP's support crew are students who mainly cater to windows.However,he claims that this application works fine with others using Linux. I have reinstalled the application but get the same results.I have looked into the crclient.conf file and the properties seem ok.However the giving the ipaddress gives segmentation fault. 1.I want to make sure I got all the configurations right in the right places(I am not confident about this one as I am very new.)Something like a checklist would be of great help. 2.I want to check out all the options to make sure that it is the fault of the ISP's application and not anything else that I did.For example I don't know whether to use the option of "automatically configure DNS" in Gnome or manual is better. 3.Is there a way to manually configure instead of installing the application?(just like the dialup connections in windows which u can configure instead of installing an application). thanx a ton, Jared |
what i know about these softwares is that with these u can be autheticated on the network of ur ISP
try looking for the same application in the search option here at LQ meanwhile i am looking for the same |
