I'm using crunchbang (jaunty) on an old desktop at home that I intend to use as an ssh server. I have everything set up and ready to go, I can ssh just fine if I'm on the same network (on my laptop) as the server, but when I tried remote access, I realized that I had the general IP (192.168.1.100) and that I needed to change the IP address to ssh remotely.I have tried to manually change the /etc/network/interfaces file but have only gotten confused.The question is what do I change and where in order to get a unique IP address for my ssh server to ensure a successful remote connection?
I use GNU MAC Changer. It changes my local network connection mac adress properly. But it does not changes my wireles mac adres. I try it with sudo ofcourse the error which i get is : "ERROR: Can't change MAC: interface up or not permission: Too many open files in system". I disable the wireles connection and then try to change the mac but i get the same error. I try these commands :
# ifconfig eth0 down # ifconfig eth0 hw ether 00:80:48:BA:d1:30 # ifconfig eth0 up
I have setup a machine with Ubuntu 10.04 server and i have installed a KNC card for Streaming the channels. Everything is good so far and here is the real deal .. i wanna change the MAC address of the KNC card to try different things. I know how to change the MAC address of the LAN card but not sure about the KNC card. I tried few things by installing macchanger.. but didn't work out. Can any one tell me whether its possible to change the MAC of the KNC card and other tricks.Here is a little info:-
[ 11.344208] saa7146: register extension 'budget_av'. [ 11.344704] budget_av 0000:04:01.0: PCI INT A -> GSI 22 (level, low) -> IRQ 22 [ 11.344739] IRQ 22/: IRQF_DISABLED is not guaranteed on shared IRQs
As I try to change my if0 MAC address either from /etc/networking/interface, or from GUI application, when I try to reconnect (through GUI) the application automatically creates some sort of alias interface with the default MAC every time, and leaves the one with the changed MAC aside.
I have followed some instructions to change to a static ip address and have now lost my connection to my router. The mistake I made was not copying the original "interfaces" file before making changes.The file originally had: auto wlan0 iface wlan0 inet (something - I thought it was loopback but didn't work when I added it).
The instruction told me to put: auto eth0 iface eth0 inet static address 192.168.1.100 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255 gateway 192.168.1.1
Which I did, using my own ip numbers, except for "broadcast". I didn't add that in because I didn't have a clue what to put there. When it didn't work, I tried putting it back to what I originally had except I can't rememebr that last bit. I added dhcp instead of what I thought it was but this didn't work either.
Now I'm not too clued up about networking and IP addresses. However, I know that I have an IP address for my router (which is dynamic) and then all of my machines have internal address e.g.
192.168.0.2 192.168.0.3 etc...
My server, had the internal address of 192.168.0.4 but now has changed to 192.168.0.7 what causes this to happen? I have to change my port forwarding on my router to allow access to my server from outside my network.
My Ubuntu One account. I had intended to change my email address, but after entering the second address, I find I cannot delete the original. I have the second one set to my primary, but I can still log in with either. I'd like to be able to permanently delete the first.
My laptop has an internal Broadcom wireless adaptor. It works fine for basic Internet access, but I cannot change the MAC address with ifconfig. I would like to be able to change my MAC address. Since this is a laptop, the only option for me to do this is a USB wireless adaptor. But compatibility is very hit-or-miss. I've already tried two USB adaptors that had been stated to be compatible with Linux, and while both worked for basic functionality, neither allowed me to change the MAC address.
For whatever reason, this information seems very, very difficult to find. I have spent upwards of ten hours cumulatively searching forums (including this one) and other resources, and have found only vague, outdated, or outright false information regarding USB adaptors that support this. I believe I will be doing a great service to other users like myself by getting this question directly and conclusively answered for once, and the more responses, the better.
Questions: Do you have (or know of) a USB wireless adaptor that actually allows you to change the MAC address?
If so, what is the specific brand and model number, and what steps were necessary to install the drivers?
Im running ubuntu server 10.10 on my wirtual mashine at home. For now i have few service installed and configured:apache with phpand mysql support,ftp,phpmyadmin.. My ip address is not static, i tryed to configure by following some guide but without success.
First i edit this in /etc/network/interfaces (changing dhcp to static
Code: # The primary network interface auto eth0 iface eth0 inet static
change my WLAN0 MAC address in my Kubuntu Natty 64 bit at every boot. I have done quite a bit of searching and found some procedures that appear to have worked back in 9.04 and before days but I have been unable to get anything to work for me in my 11.04 install. I have tried adding a script to if.pre-up.d and also tried adding a bootmisc.sh and either I did them wrong or they are not working. I want to make sure that every time I bring the wireless up in Kubuntu that I have the changed MAC address. I usually keep wireless disabled and turn it on just when I need it.
Background so you don't think I am doing something nefarious... I am going on a cruise soon. The cruise line sells wireless internet subscriptions for the duration of the cruise but they tie it to a MAC address. I am bringing my CDMA android phone that unless I use VOIP will be unable to call at all or at least with very high charges. But I also want to be able to browse the internet with my laptop. I figure it will be easier to spoof my phones MAC with the PC than the other way around. I just need to turn one device off if I am using the other. I need the MAC address to be semi permanent so I don't turn it on by mistake and have forgotten to change the MAC.
I changed my ip address to a static one. Hope did it correctly. Now when I try to ssh or sftp I get this.The authenticity of host '192.168.1.28 (192.168.1.2' can't be established.RSA key fingerprint is 6b:31:28:58:ee:2b:77:36:08:64:a1:33:85:3c:f1:1f. Are you sure you want to continue connecting (yes/no)?
Some people may need to change the mac address of their ethernet network cards. This can be easily done with fedora with command line. Just follow the steps below:
1. Log as root on a textual console (ctrl+F2) or through "su -" command in your console
Here, eth0 is the ethernet interface of your system. The mac address is put in red.
3. Change your mac address using the following syntax
ifconfig eth0 hw ether 00:18:8BA:7E:90
The new value (in green) must be hexadecimal
4. if you have a dhcp server that distributes the adresses automatically, then request a new adress for your eth0 interface
[root@localhost ~]# dhclient eth0
5. Now, your interface is up and have a new mac and IP addresses. This feature may be useful if the network administrator ban you according to the mac adress, for example .........
I have a dual-boot laptop where both are configured as clients for bacula (backup software). Since it is a laptop and it gets used outside the network where the backup is done, I can't just assign a static IP and be done; it really needs to accept an address via DHCP.
Changing the MAC address is easy:
Code:
But if you do this manually, then you'll need to restart your connection. I don't want to do that, I want the laptop to just come up with the correct address in the first place because one day I will forget to change it and the backup system will be very confused (and I will be very sad when I find myself needing that backup).
The solution is to run an init script prior to starting the network. Below is the script I am using, with someone marginal comments. It is based on the network script in /etc/rc.d/init.d, heavily edited. You will need to add one parameter to your ifcfg-ethX configuration file to set the desired MAC address. That parameter MACADDR does not seem to be used by any of the init scripts. You will find it in some of the scripts in network-scripts, but it is not used as an input parameter, but rather set by querying the NIC, thus this use does not conflict.
I've just reinstalled F14 with KDE rather than Gnome and I'm finding that I'm unable to assign a static IP address to my wired connection.
KDE automatically connects via DHCP, but when I go into KDE's network manager, the eth0 connection isn't listed. In fact, no wired connection is listed. If I manually add one with the correct settings (including a static IP), it switches back to DHCP upon rebooting.
How can I get around this? Should I install the networkmanager-gnome package?
I need to change my Mac address to be the same as another computer. My university for some reason only allows 2 computers per jack i think! and i have 3. for some reason when i plug my 3rd PC in i lose connection on my other two. i have a win 7 laptop and a Ubuntu laptop. I want to setup a small server since my school blocks all ports off campus i can't use it off campus but i want to use it on campus.
My 3rd PC is a ubuntu Desktop is there a program i can use or a command i can use to spoof the mac address.
I have an old Suse 8 installation on a vmware-host, where I had to change ip-addresses. Now something isn't working as it shouldn't: - Proftpd isn't recognizing the old pw's (coming from a my-sql db) I am not a real expert on linux, where is the address "192.168.1.37" configured on my machine? The Mysql daemon is running on this IP.
I can ping it: Code: web10:~ # ping 192.168.1.37 PING 192.168.1.37 (192.168.1.37) from 192.168.1.37 : 56(84) bytes of data. 64 bytes from 192.168.1.37: icmp_seq=1 ttl=64 time=0.024 ms 64 bytes from 192.168.1.37: icmp_seq=2 ttl=64 time=0.023 ms ifconfig result: Code: web10:~ # ifconfig -a eth0 Link encap:Ethernet HWaddr 00:0C:29:79:47:DF inet addr:88.198.100.35 Bcast:88.198.100.39 Mask:255.255.255.248 inet6 addr: fe80::20c:29ff:fe79:47df/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:563 errors:0 dropped:0 overruns:0 frame: TX packets:272 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:58845 (57.4 Kb) TX bytes:23467 (22.9 Kb) Interrupt:19 Base address:0x2024
I purchased a Dell Notebook n4030, that came with the wireless adapter from Broadcom BCM4313. It's been a while since I've been battling with the Broadcom driver to make it work perfectly. I did it!
But some servers I work with wireless in my town and I need to always be changing the MAC Address of my wireless adapter. Whenever I make the change, which is in the Linux distribution is already using it, when I enter the command:
Come to me the message:
Then I give an UP interface, but after that the adapter does not get the IP address of the network.
I'm using comcast, and I setup my server, everything works fine.But later I found out that the server inet address is changing everyday, and it makes my server almost not accessible.Is there anyway to fix that problem??
In order to change the MAC address I do: ifconfig eth0 down hw ether ff:ff:ff:ff:ff:f0 When the ff:ff:ff:ff:ff:f0 is the new MAC address. Now how do I cancel that change and return it to the real MAC address of my NIC?
I have just changed my gateway address,now I can access internet with my browser but unable to run add/remove software as it says no network connection available,system updates are not working as well. What should I do make these working?
Despite what the man page says, and what I have read out on the web, I cannot get the mail command to let me change the "from address" I have tried to change the reply address (-R my@address.com) I have tried to change the from address (-f my@address.com) ..... and so on Anyone have any luck, from the command line (as I am setting up cron jobs) in changing the "from" address? echo test | mail -s "This is a test" user@domain.com (this is the basic command I wish to use, but change the "from address")
