I try to use the "ping -a" command for getting an audible ping. But there is just silence The command "beep" works fine, so everything should be ok with the speaker (in the konsole).
View 3 RepliesI 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.

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 a debian server installed with a static ip. Now i am able to ping my ip, but when i try to configure a domain name with the nameserver as my ip, i am not able to ping the domain name
eg:
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.

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.
When i ping www.google.es, i get something like:Quote:

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:

Ping by IP - the responses come VERY quickly one after the other:

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 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.

To connect to net I have to first run dhclient3(learnt from this forum!).It gives me my ip but where is dns address sent I don't have and idea.
When I execute a command (ping or telnet or ssh) on ip 192.168.0.20 it is ok.
If I execute the same command on

ip 192.168.0.18 instead of
ip 192.168.0.20
And it's the same for others ip if I put a 0 ahead last byte.
If I type

should I receive a reply?
I have 2 windows PC and a linux as router in the linux there are 2 NIC eth0 and eth1. I created DHCP on eth0 and manually configured on eth1. My eth0 gateway was 192.168.26.253 and my eth1 was 192.168.22.253. I needed to ping the 192.168.26.x WinPC1 to WinPC2. What command I will use on linux so that the WinPC1 can ping to WinPC2.

View 3 Replies View RelatedLet's say I am pinging a host, and want to output to a file each reply and its timestamp of when this started.
I know that it can be done with a loop and a shell script. Something like this
DO
echo "$(date)" >> results.txt ###includes the time and outputs results to txt###
ping -c 4 HOST >> results.txt ###a total of 4 pings at a rate of 1 per second###
REPEAT UNTIL USER PRESSES CTRL-C
Now, my first issue is that I need to be able to see results real-time as well.
Is there a way one can print to BOTH a screen and output? If one uses the ">>" command, it is essentially sending everything to the file. Running another ping command in parallel is not an option.
how to write a command (for loop) that would ping a Class C subnet to make it so that it only replies once and does not show the statistics?

It can connect to internet via my wirelss rt2870 driver (Ralink, Belkin usb wireless). But I cannot ping any of my other computers in the home network (served by a Belkin N+ wireless router). Other computers can ping it.
I am also connected via ethernet directly to another desktop. Last night I can access the shared file (samba windows share) in this other computer, using ethernet (disabling wireless). Today I cannot. I cannot even ping it or any computer, or itself.

I have a NAS which I've re-installed with DEBAIN. Mostly its all working great but when I tell it to ping a NetBIOS name it takes 10 seconds per attempt rather than 1. Despite this it actually resolves the NetBIOS names very quickly (the first line from the ping including the IP address appears almost instantly) it just sits there for 10 secs every ping.

I'm really struggling to track down what may be causing this as it is strictly when resolving NetBIOS names yet it finds the IP immediately.
i am running debian testing and the last few days i was trying to ssh to another pc on my network and i was getting an error like there was no machine with that ip! then i tried pinging to it with no luck! ARP was the only tool that returned the MAC address of the machine and that is strange i think. i realised then that i could only ping the gateway and localhost (127.0.0.1 not my ip). after editing my /etc/hosts, i could ping my ip as well. what is so wrong? here are some useful things:
my new /etc/hosts:
jack@debian:~$ cat /etc/hosts
127.0.0.1 localhost
127.0.1.1 debian.local debian

How I can ping my debian computers on their hostname?
I have installed both samba and winbind and I have also changed the line in /etc/nsswitch.conf to:
Hosts: files wins dns
I have done the same thing on another linux box (ubuntu) just to see if that worked and it did - I could ping it on the hostname.
Also, I have trid to add the ip/hostname in /etc/hosts and even that didn't work.
The /etc/resolv.conf seems to be as it should.
In the /etc/hostname the hostname is updated.
I have tried to restart the samba service and the networking service and even the entire computer but none of it worked.
