I am running centos 4.5 Kernel. 2.6.18
My ifconfig is broken. and i dont know how to fix it.
I go into /sbin and i see the file but when i try and execute the command is says bash: ifconfig: command not found.
The permissions on the file are as follows:
I'm a relatively inexperienced with Linux, coming from a Windows background, and I struggling to solve a troublesome issue attempting to set a static ip address to a Live Debian USB Key. I know it is possible to utilise the 'ifconfig' function to set a static ip address and use 'route' to set the gateway, e.g.
ifconfig eth0 10.0.0.40 up
route add default gw 10.0.0.130 eth0
..however in both cases I need to explicitly set the 'eth0' to point at the appropriate adapter. However, this is where my problem is...
I'm creating a persistent USB key using the Debian Live CD, I'm going to create an image and then duplicate that image to a load of other USB keys. Again, not a problem as such but there are cases where I need to specify a static IP address and gateway rather than using DCHP.
And here's where problem raises its head.
Because I've created the key on another machine it has allocated 'eth0' to a specific MAC Address (assigned in /etc/udev/70-persistent-net.rules) but when I place it into machine with a different network adapter it is assigning to 'eth1' (and this increments up).
a) call 'ifconfig' and 'route' without having to identify the adapter or
b) change the script that is creating '/etc/udev/70-persistent-net.rules' so it overwrites the 'eth0' entry with the only applicavle network adapter for the current hardware.
Following is my ifconfig output code...
I want to do some thing grep that I see the IP corresponding to each LAN card?
Is that possible?
I have to change my MAC address in order to get an IP lease via DHCP. But almost no installer CDs have ifconfig and dhclient.
ifconfig eth0 down
ifconfig eth0 hw ether 00:22:15:C0:27:23
ifconfig eth0 up
dhclient eth0
Is there any way to change a MAC address within Debian or Ubuntu installer CDs?
When i type 'ifconfig eth0 192.168.25.1 255.255.255.0' the outcome is 'SIOCSIFADDR : invalid argument', but when i check the ip address using /sbin/ifconfig i see the ip address is updated to 192.168.25.1 and is up. When i restart the linux box,the /sbin/ifconfig is reset to 192.168.100.1 .what should i do so that the linux box /sbin/ifconfig should not change when am rebooting.

View 7 Replies View RelatedI would like to create several aliases to eth0, but have the addresses assigned by DHCP instead of being set to static IP's. Is this even possible? All the examples I've seen assign a static IP using the command:
ifconfig eth0:0 192.168.1.11 up
I am usually sshed into different boxes and i forgot what ip I am logged into sometimes. Is there a command I can type to give me the ip on the box I am on.

bash: ifconfig: command not found
When I try execute a variety of basic commands (including ps, ls, ifconfig, locate), I receive the error 'no such file or directory'.
Here are some suggestions that I've found online, that I have tried without success: I did a 'whereis ps' and found the file in the /bin/, and have checked that '/bin' appears when I do 'echo $PATH' I did a filesystem check which showed my hard drive as being clean I tried doing a 'sudo chmod 777 ps' but was told that I dont have permission. I don't think permissions for these files would have changed though (and I can't check as I can't run the 'ls' command).
On my system (OpenSUSE 11.4 - kernel 2.6.37) ifconfig indicates different interrupt number for eth0 than proc aqd sys file system.
ifconfig indicates 17:
proc fs indicates 43:
sys fs indicates 43:
Relevant part of lspci -vv output for irq 17 (this belongs to wlan0 and not to eth0):

where are the interface configurations (set by ifconfig, not the static ones) stored? I'm asking because I'm trying to understand, more broadly, the order of IP address lookup. If I ping the local machine (localhost, or one of the interfaces) no messages get sent out (at least according to wireshark), so some local lookup must be taking place.

1)PC1 "ifconfig eth1 down" on linux shell.
2)Check the "ifconfig eth1" on PC2
3) The running flags are unset first(disappear)and set(Re-appear) on the eth1 interface on PC2.
4) unset and set toggling happens with in short period of time about 1 or 2 secs.
This is clearly observed in linux 2.4 kernel with some time delay for the toggling, but 2.6 kernel this will happen every quickly..

i know this is crazy, but im using a [URL] and have loaded a copy of "red hat linux 7" on the computer. i have no idea what kind of hardware config/spec stuff i should have in my immediate vision, and if i did i'm not sure how i would make sense of it all. linux loaded fine. didnt save drivers. eth0 not showing in ifconfig report, but lo is connecting to network, other host cannot ping linux and vice versus
can mount a cdrom, but not a usb flash dont quite understand how the load methods work involving /mnt/cdrom/"usbutils-0.86tar.gz" eth0 problems and gnome rpm stupidity keeps me from upgrading sys from old version to a newer version, cant even find the cmd to show me that info, sorry. have usb files i want to mount, dont know how to loAD THE CDROM FOLES, SO EVEN THAT ISNT WORKING OUT HAVE DISCS WITH howtos just need to stay focused on steps to get desired end result, while trying to learn too much info for what im currently doing between all the f!@#@ing windows i have open.
I'm trying to install a Linux driver for my wireless network card (D-Link DWL-G510) on my Red Hat Linux 7.1 machine with a 2.4.37.9 kernel. I downloaded the serial monkey driver from the sourceforge site and was able to successfully compile the rt73 module and load it into the kernel. The problem now is that everytime I issue the command ifconfig wlan0 up it keeps returning with the following error message: wlan0: unknown interface: No such device.
I'm at a loss as to what to do here. I specifed wlan0 as the alias for the rt73 module in the modules.conf and also tried to load the driver with the command modprobe rt73 ifname=wlan0 (this specifies the interface name according to the instructions packaged in the driver), but the error message still keeps coming up.
Is there something else I need to do in Linux to configure the wlan0 part or is the module not recognizing the wireless network card? It would be quite strange if it is the later since all information from the Internet is indicating this is the linux driver I should be using for mentioned wireless card.

View 8 Replies View RelatedI have seen this in fedora 8/9 systems :- when I configure the eth0 card and give it a ip address using the ifconfig command from the terminal window and then check out the card from the network config GUI subsequently, it doesnot reflect the ip address as configured through the ifconfig command. However, the ifconfig command continues to show the new ip address as usual. If I need to change the ip address of the eth0 interface which should be the prefered mechanism - the ifconfig command or the GUI. Ofcourse I understand that, for the ifconfig command mechanism a line would have to be added to the rc. Local file so that the change is effective on every subsequent bootup.

Here it's the output of ifconfig on VM's interface in just 10 seconds interval:

I have a command that I run to renew my mobile broadband connection. It works from the terminal, but not in my crontab. My connection usually drops out after being connected for a week or so. So I tried to make a cron job to check the connection every 15 minutes (when there is an IP address on interface ppp0, then it is connected, so if there is nothing, I restart network-manager and it reconnects)
works from my terminal, but not when run as a cron job. If the schedule the above script to run every 15 minutes, it restarts network manager every 15 minutes, so I think ifconfig isn't working from cron. Is there some caveat about ifconfig in cron?
I have a problem with the network. Worth two network cards and Ian wan. Do not take the ip. When the system boots not included until you do the command ifconfig eth0 up. The network card is connected to a router, he does not see it. Router working, tested. Network card is working well, tested on Windows. RX RT packages go, withheld support for ipv6 and packages no longer go.

when I get the routing table, the gateway is setten to the 10.64.64.64 and when I look my Ip address global I found it's 175.157.64.119.
I'm using Debian Jessie (with YunoHost v2). Recently the PC on which I had installed it stopped working (power supply dead) so I put the hard disk in another PC. The system seems to start up correctly but I cannot see the ethernet and wlan interfaces in ifconfig (only lo).
The old PC was an Asus EeePC 1001 HA. The new one is an Acer 5920G. I ran Linux (Mandriva) on it in the past with no difficulty.
lspci shows this:

I read on the Web that BCM5787M uses for driver tg3 and this appears in lsmod:

I cannot seem to create a tun device using ifconfig, even though the module is loaded, and the node tun is present in /dev/net and appears to have correct access permissions, trying to use nstx which requires the tun device. Only thing I can think of is adding an alias, but not sure where, since there is no /etc/modprobe.conf or /etc/modules.conf in SUSE 11.3.
View 2 Replies View RelatedI have created my own distribution with susestudio.com , based on jeOS template and it works well But I have some problems with network configuration. I make a default configuration with susestudio ( configuration -> General -> network ) and I put for example 172.16.0.185 address. I also put a script which configures IP address with different informations coming from for example a serial port to make my own IP address. This script make the new address and call the ifconfig system program. For example, the script calls "ifconfig eth0 172.16.0.182". And now, I can ping the two addresses, 172.16.0.185 and 172.16.0.182. Is this normal ? I thought the new command "ifconfig eth0 172.16.0.182" would overwrite the old value ( 172.16.0.185 ). It works as this on other distribs ( like ubuntu ) but not on opensuse.
I know that I can have 2 addresses but using the following syntax : "ifconfig eth0:1 A.B.C.D" (if kernel supports aliases ) , and I don't know if it is normally possible to have 2 address from the same subnet. How can I overwrite the default config , and not to have the first address available ?
To get internet access on my second computer I have to follow the manual routine detailed below:
sudo ifconfig eth0 down
sudo ifconfig eth0 hw ether ..........
sudo ifconfig eth0 up
sudo ifconfig eth0 ....... netmask ........ broadcast ........
sudo route add default gw .........
where the various ........ represent the relevant addresses. This is necessary because my ISP only recognizes one computer - my first one. The above works fine, I simply copy and paste the above from a text document, but I would like to know which files I can alter/create so that all the above is achieved automatically when I boot my second computer.
I am trying to manually set up a number of static IPv6 addresses to one of the physical network interfaces on my 8.04server box.
I tried to use the "ip" utility like that:/ip addr add [myIPv6addr] dev eth0 label eth0:0
which was accepted by ip (no errors) and the IP address was correctly assigned to eth0. But using "ip addr show" I do not see any reference to the label I defined and "ip addr show dev eth0 label eth0:0" does not come back with anything (empty output).
This seems to contradict the information I found on the ip manpage and I wonder if this is a bug or a misconfiguration on my side. Did anyone successfully used the label functionality with ip?
I manage to get Ethernet over Firewire working between my Windows XP desktop and my Ubuntu 10.10 laptop.However, I am getting tired of having to manually issue the ifconfig command every time.How can I automate it so that the command is done at bootup?
