Hi :)
I have a Cable Internet (Assigned IP etc) to connect to internet and I want to connect another computer to same line of cable as well. Both in Same room. Any suggestion, affordable solution please?
While establishing mirroring without witness at last step i am getting an error:
One or more of the server network addresses lacks a fully qualified domain name (FDQN). To start mirroring without using a FQDN, click "yes". To specify the FDQN, click "no". Then specify every TCP address by using the syntax for a fully qualified TCP address, and click Start mirroring again.
TCP/IP are in enabled mode in Computer management.
How to rectifity this error?
I've got an Acer Aspire One running Linux. When I connect to my building's wifi, everything seems fine for a short period of time (I can google a few things or start downloading an Apt package), but then other devices on the network lose their IP addresses. Shortly after that, my computer also gets disconected. My computer is set to use DHCP.
What causes this, and do you know how it could be fixed? Am I causing a broadcast storm?
So, I am sitting in my office with four computers on the same network and internet connection.
Two of the computers can visit this particular website. Two of the computer get a message "Google Chrome could not find". I have tried FF and IE also with the same problem.
I can view the site 90% of the time on two of the working computers although the site seems slow and sometimes I also get the same errors as the other two computers.
I have flushed the DNS, reset the router, tested the site on other peoples computers with success.
Is this likely to be a site issue, an ISP issue, a hosting issue?
Any advice is greatly appreciated.
Here is the ping from the working machine:

I'm total newbie at tcp/ip and I was experimenting with Wireshark.
What this mean:
1824 578.194204 xxx.xxx.xxx.xxx yyy.yyy.yyy.yyy UDP Source port: 17500 Destination port: 17500
In data I can see that my user pc name is sent (happily it's a generic name): does this mean someone is trying to hack my pc ?
My computer is already connected to a 100Mbps LAN.
I can use wvdial to connect to internet using a modem when I have my LAN disconnected.
Now, I want to share this modem
internet to one of the ip address
available on LAN say 10.100.99.56..
First of all, can it be done?
How do I go about doing that?
Hi, I would like to mount a remote file system (A) using SSHFS, but sometimes I have IP address, access from which is not allowed. So my plan is to access it via another machine (B) in that network. Do I need to mount A on B and then to mount B (and A) on my local computer? Is there a better way to do it?
My httpd server has stopped working, within /var/log/messages I got the following error:
May 10 08:08:30 linuxbox kernel: httpd[25353]: segfault at b7fb7991 ip 009ca63b sp bfec3d50 error 7 in libapr-0.so.0.9.12[9af000+1f000]
Can anyone shed light on how to fix this, i've tried ghosting the drive, then removed apr and re-installed, but the error keeps coming up.
This is similar to some other questions, but I have a specific need which is not covered in the other questions.
I have an Ubuntu server (11.10) with two NICs. One is built into the motherboard and the other is a PCI express card. I want to have my server connected to the internet via my NAT router and also have it able to wake from suspend using a Magic Packet (henceforth referred to as Wake-On-LAN, WOL). I can't do this with just one of the NICs because each has an issue - the built-in NIC will crash the system if it is placed under heavy load (typically downloading data), whilst the PCI express NIC will crash the system if it is used for WOL. I have spent some time investigating these individual problems, to no avail.
My plan is thus: use the built-in NIC solely for WOL, and use the PCI express card for all other network communication except WOL. Since I send the WOL Magic Packet to a specific MAC address, there is no danger of hitting the wrong NIC, but there is a danger of using the built-in NIC for general network access, overloading it and crashing the system.
Both NICs are wired to the same LAN with address space 192.168.0.0/24. The built-in ethernet card is set to have interface name eth1 and the PCI express card is eth0 in Ubuntu's udev persistent rules (so they stay the same upon reboot).
I have been trying to set this up with the /etc/network/interfaces file. Here is where I am currently:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 192.168.0.3
netmask 255.255.255.0
network 192.168.0.0
broadcast 192.168.0.255
gateway 192.168.0.1
auto eth1
iface eth1 inet static
address 192.168.0.254
netmask 255.255.255.0
I think by not specifying a gateway for eth1, I prevent it being used for outgoing requests. I don't mind if it can be reached on 192.168.0.254 on the LAN, i.e. via SSH -- it's IP is irrelevant to WOL, which is based on MAC addresses -- I just don't want it to be used to access internet resources.
My kernel routing table (from route -n) is
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 192.168.0.1 0.0.0.0 UG 100 0 0 eth0
169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 eth0
192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1
My question is this: Is this sufficient for what I want to achieve? My research has thrown up the idea of using static routing to specify that eth1 should only be used for WOL on the local network, but I'm not sure this is necessary.
I have been monitoring the activity of the interfaces using iptraf and it seems like eth0 takes the vast majority of the packets, though I am not sure that this will be consistent based on my configuration. Given that if I mess up the configuration, my system will likely crash, it is important to me to have this set up correctly!
I migrated a VM running Windows 3.11 for Workgroups from VMware Workstation to ESXi 4.0U1 and the networking inside the guest machine has stopped working.
I reinstalled the network card driver, and changed the VM to use a static IP but it doesn't help.
Pls help me.
My hosting environment using Server version: Apache/2.2.14 (Unix) and I am modifying ./usr/local/apache/conf/httpd.conf to set environment variable and restarting the server .
SetEnv XML-RPC-IPs 193.45.32.21
I did set it as a first entry in the file and restarted the server . But even restarting if I try to print it is still getting me black , Am I missing any thing ?
echo "My IP address ".$_SERVER['XML-RPC-IPs'];
Thanks for your help Regards Kiran
I asked if proxies really provide anonymity, and would like to know how hackers do it when they try to attack government websites and such.
They hack PCs making them zombies and them controlling them, using their victim's IP address for example? They connect to it using a VPN, what?
(I'm just curious)

This might be a dumb question but DRAC/ILO both have HTTP server interfaces.
If I were trolling IP's port 80 on and I came across such a page I'd know it to be a high value target in the sense that if I can crack it, I can take control of the server to some extent (potentially installing another OS).
Other than changing the port, what are the best practices for securing DRAC/ILO on public Internet facing machines?
I'm on my localhost PC. I need to add an entry that maps our public site to our dev server.
I tried several things with no luck:
192.168.1.40 oursite.com // where the IP here is our internal dev server
or
devserver oursite.com
oursite.com devserver
I'm not sure what I'm doing wrong here.
I sometimes gets an ip address of 169.254.111.111 received for my laptop (instead of one in the 10.0.0.x range). I thought it was a problem with my Ubuntu system, but after I dual-booted I got the same problem under Windows Vista with the same laptop.
What's the problem, why does it happens only sometimes, and how can it be solved?
For the record: I'm using a Linksys WRT610N wireless router.
Assuming port forwarding is done on router, can the router forward if the data is coming from local machine, rather than remote.
For example: Sender targets ip like:88.251.xxx.xxx, port 8999.
Receiver listens to that port.
Router, forwards 8999 to receiver.
They are all on local network.
Should it run well?
After installation of nginx webserver, i run my website in firefox. It works good in firefox, i can see my website template is looks good, but in internet explorer it is not working properly, i can't see my webpage has text and images and every content in bad style. Like images are not loading, may be css is not working. Please help me to sort out this problem.
Before this i was running my website on apache with different ip address and moved to nginx.

I want to create a Windows Powershell script to extend my partition through WMI (remotely), IP Address of my host id 10.10.10.10
$pass = convertto-securestring "abc123#" -asplaintext -force
$mycred = new-object -typename System.Management.Automation.PSCredential -argumentlist "10.10.10.10\Administrator",$pass
Invoke-Command -ComputerName 10.10.10.10 -Credential $myCred -ScriptBlock {"rescan","select volume 2","extend" | diskpart}
Do we have any method with use of Invoke-Wmimethod
How do we configure two (2) LAN cards on one computer. One LAN card is connected to the internet via the DSL through a router, configured as DHCP. The other LAN card is to be connected via our office's IP/VPN (for email and other office online processes). I know it could be done, but I do not know how. By the way, the operating system is Windows XP.
Hi,
I'd like to start a service with monit but only when I have the correct ip bound to the host. Can this be done somehow with the normal config? For example I want to start a process xxx with pidfile xxx.pid, but only if host currently has 10.0.0.1 bound to some interface.
I'm have trouble transfering files again from my work PC, which is a linux machine to my home windows PC.
My work has changed it so I now need to SSH twice before I can access my PC.
So I need to:
ssh [email protected]
password: xxxxx
I then need to do it again.
ssh computer_name
password: xxxxx
I've tried accessing directly via my computers IP but to of no avail.
Is there a way I can use pscp or file zilla to ssh twice so I can transfer files?
Hello everyone,
Does anyone know the solution to this problem?
I checked my zone file and there are 2 A records
mydomainname.com. 14400 IN A ip.address.x.x
localhost 14400 IN A 127.0.0.1
I'm On CentOs 5.2, by the way.
Thanks for the help!!
I've been wracking my brain the last few days trying to setup DJBDNS on my server. I haven't been having too much luck. I have been following the guide provided by the creator of DJBDNS: http://cr.yp.to/djbdns/run-server.html
Here is a run-through of where I am:
Both services are up:
[root@Happycat tinydns]$ svstat /service/tinydns/
/service/tinydns/: up (pid 18224) 74454 seconds
[root@Happycat tinydns]$ svstat /service/dnscache/
/service/dnscache/: up (pid 2733) 2184 seconds
My /etc/resolv.conf file:
nameserver 127.0.0.1
My $PATH:
[root@Happycat ~]$ echo $PATH
/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin:/sbin:/usr/sbin:/var/qmail/bin/:/usr/nexkit/bin:/root/bin
My tinydns/root/data records:
..:69.160.56.65:a:259200
.ns1.benwilk.com:69.160.56.65:a:259200
.ns2.benwilk.com:69.160.56.65:a:259200
.56.160.69.in-addr.arpa:69.160.56.65:a:259200
.56.160.69.in-addr.arpa:69.160.56.65:b:259200

+www.openbarrel.net:69.160.56.65:86400
+www.benwilk.com:69.160.56.65:86400
Tiny dns can recognize the records set:
[root@Happycat root]$ tinydns-get a benwilk.com
1 benwilk.com:
78 bytes, 1+1+1+1 records, response, authoritative, noerror
query: 1 benwilk.com
answer: benwilk.com 86400 A 69.160.56.65
authority: . 259200 NS a.ns
additional: a.ns 259200 A 69.160.56.65
But then it comes to a grinding halt:
svscan /service/tinydns/

I'm assuming I have to set something with DNScache, and to be honest, it gets a bit confusing. I'm not sure whether to set it's IP address to 127.0.0.1 or one of the other IP addresses on the system. What am I missing from here?
Is there any problem or pitfall including ISA server into domain after ISA was installed and configured and worked for a while?
All the rules at the moment are based upon IP addresses, All Users.
Addendum 1
ISA is an edge firewall, so it is connected to one Internal network (this is where domain is) and to the Internet provider (External Network).
Addendum 2
I'm absolutely sure ISA should be a member of the domain.
