i have installed linux debian in my computer but i have aproblem , i have a ping only on my computer itself , not to gateway or other computers on my network .
Ip : 10.0.88.9
Gateway : 10.0.88.1
dns :10.0.88.7
note:when i have installed system i have no internet connection so it is not installed updates
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?).
View 2 Replies View RelatedI 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 have ubuntu 10.4 running on both my desktop and laptop. Both machines are connected to the router in wireless mode with Wifi.I can access internet from both machines without any issues, however I cant ping one machine from another. (and vice versa)
View 4 Replies View RelatedI have installed Micro Core onto a usb of mine and am running it on my laptop. I have been able to successfully obtain a connection and valid ip with my router. As you can see below my wireless connection seems valid computer-end and on my router's page it comes under the list of attached devices.Although this is all fine and dandy, I'm am unable to ping my router or any other computer on my network, I am also unable to ping my laptop from other computers on the network. Also by the looks of it I have having no trouble transmitting, but I am not receiving any packets.

i have two linux machines(machine1(rhel client) and machine2(rhel server)) i am able to login the machine2 from machine1 but i am unable to ping machine1 from machine2 fire wall is stoped in both machine
View 1 Replies View RelatedI 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 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 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). But for some reason, I am not able to configure the network. I used both Dynamic and Static IPs (both work fine in Windows) but still no go. I am using Yast Control Center for this purpose. I can't even ping the default gateway when I am using custom settings. When I use dynamic settings, it says Unreachable Network.

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 am using a dhcp network. Problem is I can SSH/ping to my machine but can't SSH/ping to my machine from the remote one(In internal network of my lab). What to do? I understand this is very little information....but I dont know what to provide.
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.
View 1 Replies View RelatedI installed apache2 on my Ubuntu machine and I am trying to access the server from another subnet. The server is connected using ethernet and has a static ip address. I can ping from the server to any machine in the other subnet but non of the machine on that subnet can ping the server. iptables does not seem to be running
Code:
# service iptables status
iptables: unrecognized service
and its rules are
Code:
# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination

What is preventing my machine from being accessed from the other subnet?
I have eth1 and eth2 connected with back to back cable on the same machine.
I configure eth1 with 11.11.11.11 and eth2 with 11.11.11.14.
I use ping -I eth1 11.11.11.14, I get Destination Host Unreachable...
using tcpdump on eth1 shows ARP request broadcast being sent out
using tcpdump on eth2 shows ARP request received, no ARP reply being sent out
Not sure whether this config is supposed to work?
I am running ubuntu 10.04 on a VMWare Server virtual machine. I have assigned the ubuntu machine an ip address of 192.168.17.101. The ip address of my Windows machine hosting the Ubuntu VM is 192.168.17.100.
From the Ubuntu machine, I can ping all other machines on the local subnet. But when I try to ping the ubuntu machine, it does not get a reply.
I have a clean, plain install and the only software I have installed is Nagios.
This is the scenario: gentoo box (distro shouldn't be relevant here) and win7 box. Gentoo box is dhcp and dns server, via dnsmasq. From win7, I can ping gentoo by both ip and name. No problem there. From Gentoo, I can ping win7 by ip, but not by name. The dnsmasq log seems to receive the name ok, it's "Tere-PC". I have been looking around for many hours now and I know there must be something simple I am not taking into account.
Code:
dnsmasq-dhcp: 55480937 available DHCP range: 192.168.0.50 -- 192.168.0.150
dnsmasq-dhcp: 55480937 client provides name: Tere-PC
dnsmasq-dhcp: 55480937 vendor class: MSFT 5.0 .....
Code:
# ping Tere-PC
ping: unknown host Tere-PC
Is there any way that dnsmasq, which is supposedly a dns server, will link this name to the given ip?
I've a weird problem about my honeypot project.

View 1 Replies View RelatedI 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.
The NetworkManager applet on my desktop states that my router is 192.168.2.1 and that my first DNS server is 192.168.2.1, but I cannot ping any hosts on my network using by name. All my other computers are windows so the naming is netbios naming, but I don't know if that makes any difference to DNS. I take it that because the other computers are windows that I need a wins client or something on my Fedora laptop. I would rather not fill out my hosts file because the IP addresses of the windows boxes may change.

It seems whenever i create a folder it creates the folder as untitled folder, but i can't change the folder name it just says "you don't have permission to rename item" but yet i created the folder and it is there. One thing i have noticed is that once i enter a folder it won't even let me move the folder.

View 3 Replies View RelatedI'm trying to run Debian server in our network. We have SSG5 Juniper Firewall set up to route traffic from our trusted network 192.168.50.0/24 to our DMZ 93.153.125.224/28I can connect / ping all Windows servers which are in DMZ. When I try to connect my Debian server instead of one of the server's static IP I'm unable to connect or ping to it. The server itself is able to connect to internet resolve DNS if I allow connection to our trusted network I'm able to ping or connect to any computer in trusted network but still unable to ping from trusted to DMZ. The SSG5 policy is set up to allow any connection from trust to DMZ and interface is set up to route all traffic.I have tried to trace the ping It'll go through firewall right to the interface needed but then it'll time out as like the server is not connected at all.
