I have connected my Windows XP2002 laptop with Linux 5.4 server through a direct LAN cable. I have made following configurations:
Windows:
LAN IP: 192.168.10.4
Netmask: 255.255.255.0
Gateway: 192.168.10.1
Linux:
eth0:0 IP: 192.168.10.1
eth0:1 IP: 192.168.10.3
Netmask: 255.255.255.0
route add -host 192.168.10.4 gw 192.168.10.1
I can ping the Linux server from my Windows, but cannot do so from Linux to Windows.
I am trying to get a Linux (Slackware 13.37) working in a Windows networking environment. The IT support for this organisation does not extend to Linux support, so I'm limited in what help I can get for this.
I'm trying to get to the point where I can get to the internet to download what I need on this Linux machine.
The situation is this (*fictitious addresses used) -My Linux machine uses a fixed IP address (10.100.150.21)
My Windows machine uses a DHCP assigned IP address (10.100.150.213)Both Linux and Windows machine are configured to access the gateway server (10.100.150.1)So, I can ping the Linux machine from the Windows machine and vice-versa.I can ping the gateway machine from the Windows machine.I can browse Windows Shares on the network via SMB from the Linux machine.I CANNOT ping the gateway machine from the Linux machine with the Destination Host Unreachable message being the error message.
For actual internet access I need to access a proxy server but since the Linux machine can't even ping the gateway server, it fails to ping the proxy.Now, I have been told the gateway is a HW based router and for Windows machine they use some software for authentication to connect to the network. This software isn't available for Linux, so that's why I've been told to use a fixed IP address.My experience of networking is pretty basic and most of the Linux setup is done via running Slackware's setup program.
So, I have an Virtual Machine running CentOS 5.4. It sits behind a hardware firewall which also does NAT'ing. I've set up plenty of these, so I know for sure the firewall and NAT rules are set up correctly. From the host, I can ping anything in my subnet and the gateway. But I can't ping anything else beyond the gateway. I can perform DNS queries and when I try to ping, it finds the appropriate IP address.But from the outside, I can ping the PUBLIC address (It's a 1 public to 1 private address NAT, not 1 public to multiple private). I've tried it with IPTABLES on and off, with no change.

Is there a way to ping the hostname in linux just like windows?

View 4 Replies View RelatedIn my office i have a network of 172.16.31.0 and a squid proxy server running, all other systems have windows XP and one system has centos. On centos system i have three lan cards and i want to test some things on it. So i assigned another IP on it of range 192.168.7.0/24 and same range on another windows system. And all the systems connected through a same network switch.
Unable to ping between Centos and Windows system. If i ping from one centos to windows system with the series of 172.16.31.0 then it replies very well but same thing is not happening in other 192.168.7.0/24 IP series.
My Windows machine can ping Ubuntu by name, but Ubuntu can only ping the Windows machine by using it's IP address. This was working fine in both directions until I purged Samba. After purging Samba, I couldn't ping in either direction unless I used the IP address. I did some reading and found that Samba provides NetBIOS functionality that allows the machines to resolve host names without a DNS. Since I'm not running a local DNS, I decided to reinstall Samba. Unfortunately, I've not been able to restore it to full working condition. I don't want to use hosts files as all the IP addresses are assigned automatically by DHCP. I want to be able to access the Windows machine by name.
View 9 Replies View RelatedI have a windows 7 desktop hardwired to my wireless router and a windows xp laptop connecting wirelessly on the same network. I am able to ping the windows 7 box by its ip address but unable to do so by its hostname. This is very inconvenient since I would like to set up a share by hostname (doesnt change) and not by ip (changes occasionally since its dhcp).

CentOS 5.5
Windows 7 machine (hostname/NETBIOS name: AwesomePC, LAN IP: 192.168.1.20)
Workgroup: Cake
No WINS server

Goal
From CentOS 5.5, have
# ping AwesomePC
resolve to a ping on 192.168.1.20
Problem
# ping AwesomePC
resolves to some random public IP that seems to be coming from my WAN DNS (openDNS) servers
ATTEMPTS
Have edited /etc/nsswitch.conf, edited line: hosts: files wins dns Have edited /etc/resolv.conf, added line: search CAKE Have installed samba (# yum install samba) and run (# service smb start), with /etc/samba/smb.conf, workgroup = CAKE, name resolve order = wins host lmhosts bcast
Does # ping even care about samba? How can I get this to work?
I am trying to ping my Windows machine connected to an open network (I'm at a internet caf) from my linux VM (also connected to the same network with a usb adapter), but I'm obtaining this output:
# ping 10.23.47.12
PING 10.23.47.12 (10.23.47.12) 56(84) bytes of data.
From 10.128.128.1 icmp_seq=1 Packet filtered
From 10.128.128.1 icmp_seq=2 Packet filtered
With high probability host 10.128.128.1 is a firewall or some router with packet filtering mechanism; but I don't understand how it can be possible to implement this kind of solution, with what kind of software or hardware? I also tried a nmap scan to my Windows machine but it returns me scan results from another host(the firewall or the router I suppose):
nmap -sS -O -P0 10.23.47.12
Starting Nmap 5.51 ( http://nmap.org ) at 2011-07-09 15:46 CDT
Nmap scan report for 10.23.47.12
Host is up (0.097s latency).
All 1000 scanned ports on 10.23.47.12 are filtered

So my questions is, how is technically possible to implement this kind of restriction within hosts connected on the same network? It's the first time I see this kind of configuration.
how to go about getting Ubuntu to receive an ad-hoc wireless ICS enabled connection. The internet connection is shared through a virtual machine running XP (with the USB wireless dongle under XP's control), on my desktop PC, in order to escape my ISP's no NAT policy. Ubuntu is on both the desktop PC (the sender), and the laptop (the receiver). The desktop and laptop also run windows 7. I managed to get my laptop Ubuntu to connect to my virtual machine XP, by setting the IP, subnet and gateway of all wireless devices, as was suggested in [URL] - I did use the Network Manager GUI, but pinging the desktop doesn't work.
Even with the IP configuration, Windows 7 on the laptop receives the internet fine. The next step is getting Ubuntu to receive. I can do any kind of configuration in a virtual machine, such as install Ubuntu. In virtual machine XP I used 192.168.0.1 with subnet 255.255.255.0 and gateway 1.1.1.1. On the laptop Ubuntu 192.168.0.2 same everything else. I understand nothing about networks. I know there is stuff I can do in the console, but how will Network Manager cope with me doing that?
I have 2 ethernet cards but when I look at the Network configuration in "Hardware Tab" I have another acx wireless network. How to delete that because In my system Idon't have wireless card..probably installed before but want delete it now.

View 5 Replies View RelatedI am building up a site-to-site OpenVPN tunnel between two locations. I am setting this up in two CentOS 5.4 boxes each containing two NIC's. I can get the tunnel up and running, and I can ping across the tunnel, however, from the client end of the tunnel I can not ping anything behind the server end of the tunnel. In other words, I can't ping anything on the server's LAN. On both servers, eth0 is the WAN side and eth1 is the LAN side.

I'm sure that the answer is right in front of me, but I can't seem to get it cleared up. I can't hit anything on the 192.168.1.0/24, 192.168.2.0/24, 10.10.4.0 or 10.10.202.0 networks from the client server.

I have two machines on this network, one running Ubuntu and the other running Fedora.
When I'm using the Wireless network on the Ubuntu machine, I cannot ping the Fedora machine. Everything else works. I can browse the net fine.
If I switch over to the Wired Network then I can ping the other machine.
I don't understand why ping doesn't work only over the Wireless. I can ping the router so I'm guessing it's getting blocked by the router but I didn't block ICMP traffic.
I tried asking on IRC and they ran out of ideas too to find out where the problem is.
I have a VPS running Karmic (9.10).
I can ssh it and it serves :80 (http traffic) very well.

I'm setting up a home network and trying to set up a Ubuntu Server (10.04) as a samba file server and a web server.I installed Ubuntu 10.04 Server and the automatic network configuration during installation failed. I've looked into host.conf, networks, interfaces, hosts and resolv.conf and either my settings are wrong or it's something else. I have a Win7 computer connected to same router and DSL modem and it works fine (edit: most of the time--- see below).
More information:
*ifconfig shows eth0 is broadcasting but without an IP address
*route shows an empty routing table

Last night I setup bind9 on my server. I created a local domain (name.local). The server's ip address is 192.168.1.254
The issue that I'm having is that with my ubuntu laptop, I can't ping the name of the server.
Code:
user@prefect:~$ ping name.local
ping: unknown host name.local
But when I do the same ping from both the server and a XP computer, it will respond.
I can ping the laptop with it's name (prefect.name.local) from both the server and the xp computer.
This is my /etc/resolv.conf file:
Code:
user@prefect:~$ cat /etc/resolv.conf
domain name.local
search name.local
nameserver 192.168.1.254
Also, when I do nslookup name.local or dig name.local, the return with no errors.
Why is it that I can't use the name of the server to access it and that only the ip address works?
I have installed Centos 5 on a virtual machine (esx4i). I set it to obtain an IP address from the DHCP sever, which is a broadband router, it has been given an IP address of 10.10.11.159 the router is 10.10.11.1 but I can't ping the router and I can't get any access to the network! I have a SCO Openserver server on the same physical box and it works fine so I know the network card & cable is ok.
View 9 Replies View RelatedI just installed my first EVER bind DNS server. I am running bind9 on Ubuntu 10.04. Everything seems to be working great except one thing: If I ping a host that I have set up in bind by its HOSTNAME the pings take 5-6 seconds to reply/print to the screen between each echo response. If I ping by the host's IP address, they echo back very quickly.
I have read that IPv6 can cause this, but I have disabled it in /etc/sysctl.conf and the problem still exists.
I know everyone says this can't be a DNS issue, but this never was an issue with dnsmasq (which i was using prior), and it doesn't make sense that the ping are ONLY slow when pinging by hostname and not IP.

Ping by hostname - there is a 5-6 second delay between each one of the responses:

I have Mandriva One 2009.0 (192.168.1.100) on one box and Mandriva Free 2010.0 (192.168.1.118) on the other. I can ping router (192.168.1.1) from both of these boxes but I can't ping one box to the other and the other way around. What's going on?.
Do I have to change some settings in router?. Or is it firewall issue on those two machines?. Both of these boxes are connected by cable. Symbol of the router: TL-WR340G.
It resides at 65.211.112.135 There are numerous domain names on this ip [URL]s Those are a few of them. Now if you try to ping 65.211.112.135 it does not respond, if you ping "www.barrierfree.us" it says pinging 65.211.112.135 but it also does not respond. BUT if you point your browser to one of the above domain names it will work, but it is quite slow.
