Debian Configuration :: Can't Ping Windows Xp Machine
Jan 23, 2010
I recently did a clean install of Debian 5, and a backup program called BackupPC. Both machines are on a small local network served by a router. Both machines have statically mapped IP addresses, done by the router via matching MAC addresses in a table of corresponding IP addresses (192.168.0.2 (HP-PC-XP), 192.168.0.3 (Debian). I configured Backup PC correctly (I think)...Upon running Backuppc, the first thing it tries to do when its time to run a backup is to ping the machine to be backed up. The name of the PC is stored in a backup pc config file. (I believe BackupPC does a DHCP request with the machine name to get the ip address, but not sure). Running the backup results in BackupPC tells me that it can't ping my xp machine. If I open up a terminal window in debian, i can successfully ping my xp machine when i use the ip address. 92.160.0.2 If I ping using the host name of the xp machine (e.g. HP-PC_XP), the ping command displays some ip address i've never seen...something like 63.123.155.104....how is it getting that and how can it be corrected?
I recall that nslookup looks at the local hosts file first to resolve the name....i look in my hosts file and found no such address (only contained localhost)....now what?

I have two machines, one has XP service pack2, second one has CentOS 5.3 (Linux), they are connected through crossover cable. I have configured everything fine but don't know why till now can't ping!
A. Windows machine settings as follows:
IP Address: 192.168.1.3
Subnet Mask: 255.255.255.0
Default Gatway: 192.168.1.1
+ Firewall is turned OFF.
B. For Linux machine, I will list everything stored in network files, logged as [root@localhost ~]# :
1. /etc/sysconfig/network:
ifconfig eth0 192.168.1.4 netmask 255.255.255.0 up
route add -net 192.168.1.0 netmask 255.255.255.0 eth0
route add default gw 192.168.1.1 eth0
NETWORKING = yes
NETWORKING_IPV6=no
HOSTNAME=localhost.localdomain
2. /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"
IPADDR="192.168.1.4"
NETMASK="255.255.255.0"
ONBOOT="yes"
BOOTPROTO="yes"
3. /etc/resolv.conf
nameserver 192.168.1.4
search locadomain
4. I restarted network service using this command:
/etc/init.d/network start
everything is fine. When checking using ifconfig command. I get the following:
eth0 Link encap: Ethernet HWaddr 00:08:0D:EE:19:66
inet addr:192.168.1.4 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr:........
[code]....
I mean I assigned the IP: 192.168.1.4 to Linux machine (Eth0). I did everything above and can't ping till now, when pinging from windows or Linux I get a message "destination host unreachable" restarted Linux many times but same result. NETWORK CABLE is working fine I tested it.

I'm running kernel release 2.6.26-2-686 on a i686 and are trying to share files between my machine and some Windows 95/98 machines. When I enter smb://ip_number/share_name in Nautilus, it works. I can browse the files. When I try the same with smbclient or smbmount, it complains.
smbclient -I=ip_number -L=//server/share gives cli_rpc_pipe_open: cli_nt_create failed on pipe srvsvc to machine tf_calibration. Error was ERRSRV - ERRerror (Non-specific error code.)

I am setting up Ubuntu to be a firewall type device for a windows computer. (I later want to use Internet sharing or something like that.) The Ubuntu machine has two NICs. The internet NIC works but one light is always orange (even when there is no patch cable connected to it). I can access the Internet fine from the Ubuntu machine. I have a cross over cable connected to the second NIC. This cable connects to the Windows laptop. The windows laptop can ping the Ubuntu machine. But I cannot ping the windows machine from the Ubuntu machine. When I try to telnet to the Ubuntu machine from the Windows machine (over port 23 or 80) it says "cannot connect."
From the Ubuntu machine I issued this command:
# iptables -A INPUT -p tcp --dport 80 -j ACCEPT
I used ufw status and found that the firewall was not enabled on the Ubuntu machine. The default gateway of the second NIC is the IP address of the Windows machine. The default gateway of the Windows machine is the IP address of the Ubuntu machine.

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
[Code]...
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.

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

I've been using Debian for about 6-7 months now. I've had a bit of a major networking problem for the past 4 months or so that I've been trying to fix - specifically, it started when I upgraded to Jessie. I can connect to wifi just fine, and sometimes I can even use the internet for brief periods of time (exceedingly rarely). Then... nothing. No network access, period. I can't ping any outside servers, I can't ping other computers on my network, and I can't even ping my router. Pages I try to load just stay "connecting" for all eternity, network printing fails, and so on.
So after four months of searching online (I've read through way more wireless documentation than I care to say), I finally gave up and admitted that maybe I screwed something up during upgrade to Jessie (as a matter of fact, I did, I had to do the upgrade in two increments [somehow] because my root partition was too tiny by mistake) and I did a clean install. Since I had /home on a separate partition, I was able to keep all my user files, but all settings regarding networking were wiped. So after installing firmware-iwlwifi so I can use my wireless card, I tried connecting to wireless! Success! Then I tried connecting to the internet... success! Briefly. The next morning I tried using the internet again, and it failed in exactly the same pattern as before.
I don't know much about what's going on here, but here's what I do have available:
I do have to use firmware-iwlwifi, which I installed by doing apt-get install firmware-iwlwifi. I don't think it's an issue with the wireless card itself (hardware-wise), the laptop dual-boots Windows 7 (that I never use anymore), and Windows 7 is able to connect to the internet just fine. Connecting directly to my router by ethernet cable works fine, I have perfect internet/network access then.
I can confirm that my laptop is receiving an IP address and that it is using ARP correctly to get the MAC address of my router (I confirmed this by doing the arp command, it has the MAC address correct, I checked from another computer with my router's config page) All other computers on my network work perfectly with my router. To confirm the router/its configuration isn't at fault, I did a full factory reset of the router, but to no avail.
Out of curiosity I tried installing Wireshark (using an ethernet cable to download it) to monitor what happens when I try to access a webpage. I'm no expert on networking, but I noticed something out place when I compare a capture from the affected computer to a capture from one operating normally - there are a lot of STP packets showing up. I did some checking around, it looks like STP is involved in bridging and more complex networking setups (involving switches, for example)... but it shouldn't be found on a home network, especially where there's no bridging whatsoever. These STP packets don't show up on packet captures done from any other computer. I've attached a packet capture from the affected computer here, since the forums won't let me attach a .pcapng file.
Here's the output from a few commands I ran during past troubleshooting sessions:
Code: Select allsudo ifconfig
eth0   Link encap:Ethernet HWaddr e0:db:55:b5:fe:06Â
     UP BROADCAST MULTICAST MTU:1500 Metric:1
     RX packets:12455 errors:0 dropped:0 overruns:0 frame:0
     TX packets:7781 errors:0 dropped:0 overruns:0 carrier:0
     collisions:0 txqueuelen:1000

I would like to ask something. Today my network Internet access suddenly slowed down, after inspecting the problem the hard way we disconnected one of our servers(ip=190, debian squeeze) from network and the network was alright again. When we plugged it back in, following symptoms were observed: computer 190 pinged gateway app. each 6th time. gateway(debian lenny) pinged computer 190 app each 6th time whole network Internet access was slowed down, local network functioned just fine
While pinging themselves, i ran iptraf on icmp packets on gateway and I saw what i thought was ping attack, lots of echo request coming from external address to computer 190. Blocking that address in iptables didn't help but restarting the gateway did, network Internet conenction is at full speed and gateway and computer 190 ping just fine.
My question is, what steps should I undertake in similar case (it's second time in 2 months) - to debug similar problems. Is it even possible for ping DOS to this kind of damage?

I have an ubuntu kk laptop connected via wireless to my mixed network (xp, win7, other ubuntu), but i can not ping said machine or connect via ssh. Internet and smb-browsing ON this machine work, as does pinging FROM it. If this was a windows machine, I'd say a firewall is in the way, but since it's a vanilla karmic install, this should not be the case (or should it?).

I have a very strange problem.ometimes, yes sometimes not all the time, I get a Destination Host Unreachable when I ping a computer on my network. If I switch to root using su I can ping that same computer. Here is a screen shot:

I've tried disabling ip6, disabling avahi and adding options single-request to my /etc/resolv.conf - problem remains. If it helps when installing Squeeze was prompted to install firmware-realtek, which I didn't have. So downloaded onto usb from another machine installed once setup was complete.

I have known for a while that my puny Celeron 633 box is running an SMP kernel but I didn't care until now. I do not remember installing any SMP kernel. It would not have made sense.What should I do to make sure I'm running a uniproc kernel? I wanted to edit config-2.6.26-2-686 and change all the lines ending in SMP=yes to SMP=no but am not sure what this will do.

I cannot remote desktop to the Debian machine from anywhere,hether within the same network, or on a different network elsewhere. Also, the personal wiki I set up on it to be viewed via a normal web browser cannot be accessed, either. Both time out when attempting to connect to them. I can still ping the Debian machine when on the same network, though.
This started some time ago when we had a failure occur on our main server.had to powercycle everything in order to restore things back to normal, the Debian machine included. Since that time, this problem started to occur. This is a major thorn in my side in attempting to prepare for our website to move,I've been unable to figure out how to fix it.Originally, I thought it would be something in between the Debian machine and anything else, which would mean something like our firewall box or our hardware switch was the problem. But the tech support people who maintain those for us confirm that there is nothing wrong with them, so now I'm not certain anymore.

My sid machine currently can't access debian.org, through apt hitting the repositories, surfing through Epiphany or Iceweasel, or pinging the server directly. It was working fine until about four days ago. However, if I type in the IP address, I can access the website, so it must be some sort of DNS issue. My home server, running Squeeze, can access debian.org just fine. Any suggestions for how to fix it?

I've installed newest Debian (Squeeze) and then on fresh system made instalation of VirtualBox OSE as it is written on http://wiki.debian.org/VirtualBox.
I've also created virtual machine, however when I try to run it I got error message:
RTR3Init failed with rc=-1912(rc=-1912)
Please install the virtual-ose-dkms package and execute 'modprobe vboxdrv' as root
And later on code...

I am setting up a mail server on debian. Once it's done, I'd like to have an indentical server on another machine, where debian will also be installed. The solution has to be hardware agnostic, so source machine is different than destination machine. I was reading on some wiki page that one can simply copy the root filesystem via rsync to the computer that he'd like to install the system on, then chroot to it and test if everything works. I'm guessing I'd have to change a couple things before, like :
- The network config
- The /etc/fstab file (disks and partitions may be different)
This article is about using rsync to transfer a copy of your "/" tree, excluding a few select folders. This approach is considered to be better than disk cloning with dd since it allows for a different size, partition table and filesystem to be used, and better than copying with cp -a as well, because it allows greater control over file permissions, attributes, Access Control Lists (ACLs) and extended attributes.

I'm trying to install the openconnect VPN client on a server machine, Debian 7 Wheezy, and APT is trying to install a lot of dependencies. I think it's trying to install the whole desktop environment.I was searching the web but all articles are for desktop machines and nobody mentions my problem with the dependencies. I also have openconnect installed in two Gnome desktop machines without problems.
This is the output:

I'm attempting to use a network bridge to connect my virtual machine, like so:
[Code]...
The issue is that when I type the following command, I get the further following horrible error message that doesn't seem to really point me to anywhere and I can't seem to find any relevant information to my problem on the web:
root@darkstacks:~# qemu-system-i386 -hda test.img -m 128 -curses -net nic -net tap,ifname=tap0 warning: could not configure /dev/net/tun: no virtual network emulation
Does anyone have any idea what I need to do here? My processor does not have the vmx flag, as it's a 2.4GHz P4. I don't know if that might have something to do with it.

I do not know if this is really something I should worry about. I am running Debian testing on my laptop (HP Pavillon dv6). Today, the aptitude update---aptitude upgrade gave me a new kernel (2.6.39). However, if I boot with that kernel, I get a warning (do not know if that is the way I should call this) telling me that the machine failed to get the i915 symbols so turbo graphics will be disabled.I have not done any serious test, but at first sight I do not notice any difference performance-wise with respect to the previous kernel. what am I supposed to do to fix this?

Have installed fedora 14 on a HyperV virtual machine, have added a Legacy network adapter in the Hyper-V settings for this virtual machine that fedore pics up as eth0. I'm pretty sure this card is able to pick up an IP address from a DHCP server on our network but I'm unable to ping any boxes from this fedora virtual machine or ping the fedora machine from another box on the network. I have tried to disable the firewall and SELinux incase it was that stopping the pinging each way but that didn't help.
