I have created a /tftpboot directory and chmod it to 777 I have put an image 'uImage' on my Debian box under /tftpboot In directory /etc/xinetd.d/ I have created file tftp:
Service tftp
{
disable = no
socket_type= dgram
protocol= udp
wait= yes
user= root
[Code]...
I keep geting timeouts although uImage is on the debian box and it appears the tftp server is running.
I am using an virtual machine. where I need to ping from one machine to another. earlier I was able to ping. But after going to google.com once, I cannot ping back to this machine.
But if I gave ping -I eth1 <IP> then I can ping.
I cannot install any package, so tell me solution which includes not installing any package.
When I try to pxe boot a Sun X4100 (which actually has a RHEL OS on it right now) I get the message TFTP open timeout. All traffic is allowed for port 69 udp in both directions. I do get a dhcp address. I see that both on the server and the client it gets an IP. After that I get this message in the logs:

Ive got a problem on my server ....installed Debian 5 , Webmin and than syscp settung up syscp ready ....
I try to ping "localhost" ansver ping: unknown host
I try to ping "localhost." there is a host with IP 127.0.0.1
I need it to change it in "localhost"
Is that the bind9 maybe?
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 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.
Configs below:
Ping by hostname - there is a 5-6 second delay between each one of the responses:
Code:
Ping by IP - the responses come VERY quickly one after the other:
Code:
/etc/resolv.conf:

rev.0.168.192.in-addr.arpa:

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.

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.
I have been using another Linux distro(Xandros) for 3 years on one computer and have just installed Ubuntu 10.04 on a different computer. I am trying to network the 2 computers via simple ethernet cards and a crossover cable so that I can gradually migrate applications, data and peripherals from Xandros to Ubuntu. I am completely new to Ubuntu and I am really struggling to get NFS to work. Each computer
can ping the other, so the hardware connectivity seems OK. I have shared the relevant directories from each computer. I have followed malco2001's ellent HowTo guide and have now reached the stage where Xandros, as client, can mount directories on Ubuntu, as server, and see the files but I cannot get Ubuntu, as client, to mount directories on Xandros. When I attempt this from Ubuntu, using the command
# mount -t nfs 192.168.1.2:/home/richard /mnt/PC2_richard
(I have already issued from Ubuntu: # mkdir /mnt/PC2_richard)
I get the message:
mount.nfs: mount to NFS server '192.168.1.2:/home/richard' failed: RPC Error: Success
The configuration of various files etc. is as follows:
Ubuntu
IP address: 192.168.1.1
[Code]...
I should mention that Xandros does not have nfs-kernel-server installed; instead it has nfs-user-server.I am sorry if I have omitted or done something really stupid but I have spent best part of a week on this with only partial success.

I have connected xp and fedora through crossover cable . xp has ip address 192.168.0.1/24 (manually assigned) fedora has 192.168.0.2/24 with default route equal to 192.168.0.1
I can ping fedora from xp computer but i can't able to ping xp from fedora computer.
I have manully edit the /etc/sysconfig/network-scripts/ifcfg-eth0 file with correct subnet mask and ip address because when i tried to give ip address manully in network manager the subnetmask is replaced with gateway address don't know why.
Now i want to share internet through crossover cable . xp is connected to internet through wireless usb adapeter.

This applies to my 2 opensuse PC's, my Windows PC is fine.I can ping a hostname, say "PC1" but I can not ping PC1.domain.local (even the host PC can not ping it's own FQDN). When I ping just the hostname the ping stats even list the FQDN.Onto the next issue, since all my PC's, have the domain prefix domain.local, my Synology can not. I can ping it's IP and that is it. I can resolve it's name with nmblookup just fine tho and that is what is killing me. How is this not resolving.Even weirder, I can browse to "Synology" in Network Servers under places on the slab.

View 9 Replies View RelatedI 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.

I have an IBM Bladecenter HS21 with 3 blade servers. All 3 blade servers were initially installed with RedHat Linux 4. I then installed ixMOS on one of the blade servers, and Mandriva Linux was also installed (over RedHat) automatically along with ixMOS.
Now, I have some network problems. The other 2 servers with RedHat can ping each other, but it appears that the server with ixMOS/Mandriva Linux is isolated, that is, I can't ping the other 2 servers from it, and I can't ping it from the other 2 servers.
Does anyone have any ideas on what is wrong and how I can solve this problem? One more thing, my installation of Mandriva Linux has no GUI, so I have to do everything using the command line interface.

When we use ping, the option -i is referred as the interval time between sending each packet. Is this interval is the same as 'Inter Frame Gap(IFG)'?? As far as I have heard, IFG is introduced in the Physical layer. So using this option can we really change the Inter Frame Gap??If I use 'ping -i 0' which means that the interval is 0, I still get some value of 18.3 or somethin as ipg in the ping output. So IFG and 'ping -i' are same or not??
