When using gateway 196.214.15.X with ip 192.168.1.X all windows pc connect to internet and email but using the same range on rhel5 it cant even ping mailbox. Why is the ip masked, can u get software to trace the ip of the gateway from the windows pc, the 196 ip is I suppose a public ip as it is the ip of my lease line? How do I get the RHEL5 running internet using the same range as the windows boxes ??
View 2 RepliesSo, 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.

ADSL modem has been connect to one of windows xp machine and by running Analog proxy, we uses internet by mentioning that machine's ip address. But how do i ping the default gateway in this case? Is it possible or not? If yes then please tell me how, because if i says # ping <anysite.com> it not pinging; its says host unreachable; means i will not be able to run wget too.
I am trying to ping from OEL 5.3. In one of google link; i read that :Does PING work through the Proxy Server? No, ping uses the ICMP protocol to communicate. Proxy only supports TCP and UDP packets. Ping will resolve the DNS name but go no further.

I have a Linux server that has local mail service. There are few user accounts on this server. User may send the mail to each other but that only restrict to LAN environment only.
For example, I may
# mail user1
To send mail to user1. User are not able to send mail to public. Some service like hylafax using this local mail service to send notification of fax status.
I don't want to manage and maintain local mail service anymore. I have subscribed a package from ISP to host a public domain of my own. I wish to have my hylafax service to able to send the notification mails to public mail server, is that possible to do it? It is great if all mails that send to local mail server may forward to public mail server. That makes the local mail service serve mail forward only.
I can ping my IP, and other PC in the same LAN, but I CANNOT ping the gateway on my 10.04LTS ubuntu. Other PC in the same LAN(Ubuntu 10.04LTS) could ping the gateway and my IP. I thought that (1)network cable is OK because I could ping the other PC in the same LAN.(2)Gateway is OK because other PC could ping it. (3)setting of operating system might be somehow wrong.
I have tried to restart the network several times and still not works. I followed the HOW-To debug tips and following is the results. Any suggestions?

(We are running CyrusIMAP v2.3.16 on Slackware 13.1)The Problem:A user deleted a HUGE public Folder (>10000 Messages, >250 Subfolders), and now the Folder is in his "Trash" folder.Besides the obvious "Why did he have the access rights to do so in the first place??" question, I am honestly at a loss as to how the user did it:Trying to copy it back using Thunderbird failed utterly, TB crashes, or copies only a part, or nothing at all... (Tried 3.x on Windows and Linux Clients)So now I'm searching for a way to copy the folder back serverside.But web and manpages seem to offer few help:I don't want to move the folder to another partition, nor do I want to reconstruct or restore any corrupted data...All I want is to copy the folder from "user/USERNAME/Trash/HERE" back to "shared/archive/HERE".

I've set a two-node cluster using Pacemaker/OpenAIS. I have only one network and if I break this one, the communication between node is interrupted ... With a ClusterIP resource, when network is breaked, then each node start the ClusterIP => 2 same IP .. Is there a way to define the prefered location of a resource when connection between these nodes is broken ?
A <==> B
If one of the node lose the network, then follow a previously written rule : start resource on A (for example). B will know than it's not the prefered node and so, will stop to serve. Possible ? This is because if both node are connected, but a problem between these node occur and client can join both node ... then the split brain is problematic ... A better solution is to add a rule when the split-brain occurs : all node wich can't reach the gateway have to stop all resources ... And so, if it's A wich lose the network, service will start on B and only B without any problem ...

I installed openSUSE on one of my work system. The network port wasn't working when I was installing, but works fine now (checked in Windows).

I can't even ping the default gateway when I am using custom settings. When I use dynamic settings, it says Unreachable Network.
View 7 Replies View RelatedBack in April I set up a Ubuntu DHCP server and a multiple VLAN network [URL] to migrate our various servers, workstations, etc off the 192.168.1.1 /24 network that everything was on because we where running out of address space. I built out the new network and everything worked great except our AD server would never get an IP address from the DHCP server (static reservation) and even if I set the IP statically on the AD server it couldn't ping the gateway and noone could log in. After several attempts to resolve this, including bringing in outside help, we where never able to figure out what the problem was.
Now 6 months later I have time to revisit the issue without effecting the live network. I used Acronis and imaged the AD server last Friday, cloned it on to another box with the same hardware, and put it up on the new network that's been sitting unused for the last 6 months. Today when I statically set the IP on the AD server (which is what I want) it connects and I can ping it's gateway 192.168.1.1 and all the way across vlans to a test sales agent workstation at 192.168.8.xxx on vlan 800 but only if I statically assign the agents station an IP address. When I try to get an IP address via DHCP it fails as destination unreachable. Nothing has changed in the last 6 months on the DHCP server but now it for some reason can't ping its default gateway 192.168.1.1. All of the config files are the same as they where left from the post linked above aside from the vlan id's used where changed from 1's to 100's (i.e. vlan 3 is now vlan 300) /etc/network/interfaces
Code:
auto lo
iface lo inet loopback
auto vlan100
iface vlan100 inet static

why it can't reach the gateway, when I do a tcpdump I can see the DHCP requests come in on eth0 but the server never responds and I'm pretty sure its because it isn't "seeing" them since it thinks there isn't a network connection but I don't know how to trouble shoot to find out where the problem lies.

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.
Even ping google's ip address doesn't work. unknown host error using backtrack4 able to browse net with these settings.
