I would like to ping all my virtual hosts in virtual machine server with a oneliner. For example like this:
Code:
for i in $(seq 1 20); do if [[ $(ping host$i.virtualhostserver.com -c 2 2>/dev/null | grep "2 received") == "2 packets transmitted" ]]; then echo $i; fi; done
The problem is, that I'm afraid my if-sentence is somewhat wrong because it never gets a match even if I know, that host is up.
Not long ago I lost all sound, but I got it back eventually-the system wasnt snesing my usb speakers.
Now its stopped recognising them again and I cant remember how I got it back before.
How do I find a list of USB devices?
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.
I get ubuntu 10.04 LTS installed on my PC and laptop , and I tried ubuntu one.It worked and I want to have a test, so I removed the two devices that already subscribed to my ubuntu one account, after that, I found I can't get them subscribed back.Everytime I start ubuntu one preference , I'll get the error message: got empty result for devices list.How can I add my two devices back to my ubuntu one account (I googled a lot and found that someone pointed that delete the ubuntu one's key will work, so if this is the right solution, how to delete it?

View 4 Replies View RelatedI have been administering linux systems for years now, but usually they are commodity boxes and as a result I rarely have driver problems, short of needing to install some "restricted" or "proprietary" driver package, or manually installing the nvidia binary drivers back in the day. However, one question to which I have never picked up a straight answer regards common troubleshooting practice. Will lsusb and lspci list device for which a system has no drivers (kernel modules)? I am trying to install a webcam on a SiS-chipset laptop and though I can see a physical webcam, neither lsusb or lspci are showing me that any webcam-like device exists. What I want to know is if it would show anything, or if it needs drivers in order to show a device?

I have an old pentium 3 computer that has ~7 NICs installed. These NICs are attached to modems and other networking equipment. According to the linux ping page on computerhope.com, it seems that one could send a ping from a certain specified NIC. How would one go about this?
View 6 Replies View RelatedIs there any way to implement a simple ping script in C (unix)? I'm programming simple OpenWRT scripts.
I have found some examples of ping in C:
[URL]
However, nothing happens, nothing is sent.
When I look at the code, in the portion where the socket is created, I can see that the socket is not binding to any interface:
Code:
if ((sockfd = socket(AF_INET, SOCK_RAW, IPPROTO_ICMP)) == -1)
{
perror("socket");
exit(EXIT_FAILURE);
}
setsockopt(sockfd, IPPROTO_IP, IP_HDRINCL, &optval, sizeof(int));
Instead, it uses "setsockopt" to set some options.
My guess is that it is trying to send packets over the eth0 interface instead over the wl0 (wireless) interface (which is the one I want to use to send pings).
Now, my question is: Is there any other way to send pings in C by binding to an interface?
Just i want to ask doubts in c programming. I dont know whether this is the right place to ask doubts in c. If this is not a correct place, may i know where can i get help for c programming?is there any active forum or mailing list for c programming?

I'm trying to build a custom setup that requires a flash drive and a CD to both be mounted to root. Applications, boot data, and other static directories are on the CD, while /home, /opt, and /tmp are on the flash drive. Is there a special option I can enter into fstab to allow this? If not, I intend to modify my kernel to allow this, but I'll need to find the sources that control this function.
View 4 Replies View RelatedI'm trying to do the following. from a php webpage click on a link, that opens a shell/cmd and runs an open ping to the device. so it must actually open a shell (for linux) or cmd (for windows) and run a ping to the specified ip.

How to get this working?
View 1 Replies View RelatedI would like to make a script, where I specify my Cisco devices IP addresses as arguments to the script and then this script automatically logs into every one of them and does "show version" and "exit" in every Cisco device. I have public/private key authentication system with my Cisco devices- thats why I'm using ssh-agent and ssh-add. I did something like this:
Code:
#!/bin/bash
if [ -z $1 ]; then
echo USAGE:
echo "$0 IP1 IP2 IP3 IPn"
[code].......
However, it logs nicely into the first device(I'm able to execute IOS commands in this first Cisco device etc) and then does nothing further.
Is it possible to create threads in BASH? I need a script with will ping a network to find out unused IP. in a for or while loop the pinging process is taking a very long time. I was wondering if it is possible to send multiple ping on the same time so this will speed up the scanning process.

View 3 Replies View RelatedI want to disable mounting usb storage devices except some devices based on its vendor id. I tried by adding below udev rule in debian wheezy
Code: Select allACTION=="add", SUBSYSTEMS=="usb", RUN+="/bin/sh -c 'for host in /sys/bus/usb/devices/usb*; do echo 0 > $host/authorized_default; done'"
ACTION=="add", ATTR{idVendor}=="054c", RUN+="/bin/sh -c 'echo 1 >/sys$DEVPATH/authorized'"
But it disabled all usb devices(USB keyboard and mouse). How can I allow other devices except storage devices.
you have to read from many devices separate devices and make it look like a single one. It sounds very much like a device driver to me, perhaps... but getting my hands dirty with kernel code sounds like a daunting task for me that I've never done it...

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.
