I had had my internet connection working using PPPoE, but after I did some tweaking and configuring on the machine (configuring Samba), I wasn't able to connect to the internet and on the syslog said:Code:Cannot determine ethernet address for proxy ARPI'm using dynamic IP address on my internet account. Is this problem related to Samba server configuration that is running?
View 2 RepliesI'm just an undergrad with duck tape and google searches to hold this place together. Anyways on to my question. Where I work, we have a tape library but no way to configure it, the backup software simply talks to the robot to load and unload tapes. There is a network port on the library and I do have the software, but have been running into problems getting access. I was wondering, is there a way to determine the ip address of this machine by plugging in a cross over cable with a laptop and scanning it? What tools could I use to do this?

View 9 Replies View RelatedI have a usb device that is setup to use a networking interface. When I connect the usb device, ifconfig automatically shows a new interface "usbX", and it has an assigned IP address, e.g. "192.168.X.1" - yes, the "X" is the same number between the address and the interface name. Each time I connect the usb device, it gets a different ip address...
192.168.9.1, 192.168.10.1, etc (actually the device address ends in .2, the PC is .1)
How do I configure this device to always have the same address? Or maybe it's more accurate to ask, how do I configure linux to always assign the network address with this device?
have a doubt about the multicast address.I have read that IP and ethernet multicast address have the same last 23 bits. While an ethernet multicast address always starts with 01:00:5E. Changing the last 23 bits of the IP address into hexadecimal form and "adding" them to the first 24 bits we find the ethernet address but what about the missing bit??? For istance I have: 230.11.111.10 = 11100110.00001011.01101111.00001010 So converting the last 23 bits I have b:6f:a The final ethernet address will be 01:00:5E:b:6f:a . And what about the missing bit?

I've just arrived at uni and to set up my wifi apparently I need my "media access control which is listed as the phsyical address for ethernet adaptor local area connection." on windows you can find it by using the command ipconfig /all but that didn't work when i put it into terminal.

2. What can be the major obligations of such a change?

I have an HP Laserjet 3.I can use it in normal Windows mode, or as a Postscript printer.it is an older printer, but it is still listed in the driver database. The cups setup tool cannot autodetect this printer. Also, if I select the actual driver for this printer, the cups tool still reports that no printer has been selected. I cannot add that driver for some reason. So, now I have to become an expert in cups configuration. Where is the cups HOWTO? Not in the SuSE howto section. Online? A little support there, but not SuSE specific. Does this local printer need to be a "network" printer? If so, how to I determine what internet address to use?

Most of the article suggests to parse the output of ipconfig /all on windows and ifconfig on linux.

Code:

What is the Linux command to clear IP address of an interface without bringing it down and/or restarting network services. Seems strange ifconfig is able to change IP address but has no option to clear it, or am I wrong?

View 4 Replies View RelatedI have a local proxy server running on my computer, but I want to add a twist to it. I have multiple connections going through the proxy, but what I'd like to is that all outgoing connections Mac Address' will be different from the one the connecting systems. Mask or even alter them, if possible.
Yes, I know the idea itself sounds weird, but I'm attempting a few ideas for a project I'm working and I ran in to this problem. Please note that it's impossible for me to change the MAC Address' on the systems connecting through the proxy (they're gaming consoles, to be specific.)
I'm currently running the latest version of Ubuntu.
I am using CentOS 5.5, I installed squid3 in that machine. From my users machine i am not able to use our webmail address. Outlook shows pop3 error.cannot ping webmail address inside proxy.

View 2 Replies View RelatedI want to configure multiple virtual ethernet interfaces over a single physical ethernet interface (eth0) and for each virtual interface the MAC address must be unique and the IP address must be Static.Finally all the virtual interfaces must be able to communicate both internally and externally and the traffic should be captured using wireshark.
I need to have such kind of setup to communicate devices individually using one physical ethernet device.
Because I was fiddling with few kernel modules like MACVLAN and MACVTAP and successfully enabled those modules and rebuild kernel. Using macvlan and macvtap I can configure virtual interfaces with unique mac address and static IPs but while capturing packets using wireshark interfaces behave weirdly.
For example say on HOST machine I have 1 physical interface and created 3 virtual interfaces as shown below.
Interfaces :
eth0 (physical ethernet interface)
IP: 192.168.A.A
MAC: aa:aa:aa:aa:aa:aa
[Code] ....
First from above interfaces I started pinging eth0 internally from host machine in which it worked as usually.
Second I did same externally from other machine which is connected to the same network of Host machine, and this did work as usually.
Third I pinged first virtual interface veth0 both internally and externally and this also works and after that I did check source and destination MAC address using wireshark tool-where both showed up there respective MAC address.
Now triggers the issue, where I pinged second virtual interface same like I did for first one, but this time ping was success and where as in wireshark tool the MAC address for veth0 is picked by veth1. This is where I got stuck and this issue happened for all the remaining virtual interfaces.
I couldn't see any virtual interface showing their respective MAC address, as of the remaining except the first virtual interface has been picking the first veth0 mac address.
How can I determine full compliance:

I tried rebooting a couple times and once that fixed it. Usually it does not. I reloaded (gasp) Windows Vista on it and it worked ok.This last time, I reloaded CentOS it hung on the bootup (ASK ??), I reset it, it rebooted and everything looks ok; for now.
The system says it is presently using driver r8169
