He's had several thoughts on how to get this done and I know very little about this kind of thing so I thought I'd ask some of you.
His first thought was to buy a multi port bridge, but he doesn't like any of the ones he's seen so far.The other thought was to connect all of the devices to a switch and then use a single bridge, but he isn't sure if this would work.
I'm running Ubuntu 10.04 on a HP Mini 1116nr as expected i have no Wireless access but i also seem to have no wired access either.
View 2 Replies View RelatedI boot linux off a USB stick on many different computers with different hardware. How can I determine in a script which devices eth0, eth1, wlan0 exist and which hardware devices they apply too? Sometimes a wireless card is wlan0, other times it is eth1 or even eth3! The proc/net/dev file does not inidicate which hardware is installed.

Can I connect both of the to the same network (if this network allows both connection) to increase the transfer rate between the PC/Laptop and the server???

View 3 Replies View RelatedI've got three network devices on a laptop:
1. Built-in ethernet LAN
2. Built-in ethernet WLAN
3. PCMCIA ethernet LAN
I installed Ubuntu Server on this computer without the last one inserted.I inserted the last one today, and it lights up when i put in the cable. To be sure if Ubuntu has found it, I tested with the install CD and could see that it found all three at the first part of the installation where I have to chose a primary device.I can't get my WLAN card working, neither do I get my PCMCIA LAN card working. The third card, this PCMCIA card, has worked on Ubuntu Desktop using another laptop. And as said, the setup finds all three.
I just loaded 10.10 on an Acer Aspire One D255. When I installed Ubuntu, network manager loaded and I was able to use both the wired and wireless cards. After I used update manager, the kernel was upgraded, and I also added some wireless applications (RutilT WLAN Manager, SWScanner, and WiFi Radar). Upon reboot, the network manager doesn't work, and it cannot find any of the devices.
View 9 Replies View RelatedThis may be more suited for the networking forums, but I figured Community Cafe would be well rounded enough for someone to tell me if this is even possible (with minimal configuration that is).There are a few places I travel where I only have a wired connection to the Internet (no wifi), but when this happens is there a simple way to create an adhoc network so wireless devices can route through my computer and to the network? Reason I'm asking is I'm thinking of getting an iPad or iPod Touch which have wireless connections, but in the cases where my laptop is using a wired ethernet connection and the wireless card isn't used, I'd like to create an adhoc wireless network that'll let such wireless devices work.
View 4 Replies View RelatedI'm having trouble getting my wifi devices to work on my 128bit WEP network. I have a new Thinkpad T400, with an internal Intel PRO/Wireless 5100 AGN. I also have some cardbus cards: a Lucent ORiNOCO Gold, a Linksys Wireless-G, and a TRENDnet TEW-421PC. I have them set up as interfaces eth2, eth1, and eth3. (The TRENDnet isn't recognised as a network card at all, so no interface for it.) I have installed the latest firmware for the Linksys card.
The /etc/sysconfig/network-scripts/ifcfg-* files are virtually identical for all of them, differing only in the HWADDR and DEVICE lines. So here's the behaviour:
1. The Lucent card comes up just fine.
2. The internal 5100AGN and the Linksys cards won't come up, and watching with iwconfig shows that they're either associated with my AP OR they've got an encryption key set -- but not both.
3. When trying to bring up the 5100AGN, I get the following messages:
iwlagn: index 0 not used in uCode key table
iwlagn: index 3 not used in uCode key table
/var/log/messages shows DHCPDISCOVER requests being sent, but they're bound to fail since the association with the AP with WEP isn't being completed. And yes, the ifcfg-* files really *are* identical except for the DEVICE and HWADDR lines. The /etc/udev/rules.d/70-persistent-net.rules file correctly maps the interfaces to the MAC addresses. So why does my antique ORiNOCO card work and thew newer ones fail? How can I track down what's being done wrong/not being done?
I'm working on a server and noticed that the to RAID5 setup is showing 4 Raid devices but only 3 Total devices. It's on a fully updated CentOS 5 system that only has three SATA drives, as it can not hold anymore. I've done some researching but am unable to remove the fourth device, which is listed as removed. The full output of `mdadm -D /dev/md2` can be see below. I've never run into this situation before.Anyone have any pointers on how I can reduced the Raid Devices from 4 to 3? I have tried
mdadm /dev/md2 -r failed
mdadm /dev/md2 -r detached
but neither work and since there is no block device listed I'm not quite sure how to get things back in sync so it's only seeing the three drives.

I'd like a way to see all of the devices on my local network and what their local IP address is. I recall that I used wireshark to troubleshoot a similar problem a while back, but it doesn't seem to have a way to see all of the devices- only the traffic. (I'd like to do this without having to physically interface with my router if possible, and I am in an encrypted network if that matters)

View 3 Replies View RelatedJust installed 11.3 kde. When running the live cd both wireless and ethernet devices appeared in the network connections manager utility. I even connected to a wireless AP.I just booted up for the first time and none of these devices are available. There is no network manager icon in the system tray, and when the network manager utility is maually opened the only connection type i can select is vpn.I know that opensuse should be able to recognize these devices since they were available and working via the live cd, so can anyone help me restore them?
One extra piece of info, is that I am sharing a home directory with a gnome ubuntu install. there were a few minor issues i dealt with initially, but i didnt need to change this user's UID like I have had to do in the past so that's good. Each time i open a terminal I get two pieces of output assuming from the bash startup saying something like.URL...I highly doubt that these problems are related, but figured I'd post. Also if someone knows the solution to that as well, that would save me a bit of googling.
I'm setting up a raid 5 on several hard disks with a layer of lvm on top for good measure.I know the recent kernels support growing software raid, but since centos runs 2.6.18, I wanted to make sure it'll work. Does the centos kernel support growing raid devices?

I am attempting to setup a network to network VPN tunnel between our main office and a temporary location. This location need full VPN access back to the main office's network.Anyhow we have spent about 3 solid days attempting to make this work without any great success. Here is our network scheme for these two devices.

External IP: 1.1.1.1 (obviously not the real IP)[code].....
I have installed CentOS 5.3, and updated with yum update. I have kernel 2.6.18-128.1.10.el5xen.
I can't get my wirelss network to work, I have AR928X wireles network adapter.
Do I need to install a newer kernel and install ath9k or can I just downlad a driver without updating the kernel?
I'm new to CetOS and Linux so I hope someone kan give me a step by step guide to what I can do!
I just upgraded from Ubuntu 9.04 64-bit, to CentOS 5.5 64-bit and my RT-73 USB network card doesn't seem to want to function. It always worked fine in Ubuntu by default (plug and play). Is there some setting I need to make to get this working?Even BT-3 (which is quite old) recognizes the RT-73.
View 19 Replies View RelatedI am trying to do 1Meg IO to one of the block devices but I can only get a maximum of 512K IO size. I can use the corresponding sg device to get 1Meg of IO. I was wondering if anyone knows why 1Meg IO to a block device is being broken down into 2 512K chunks? I have increased the /sys/block/sdg/queue/max_sectors_kb to 16384, but it has made no difference.
My uname is : Linux virgo 2.6.18-128.el5 #1 SMP Wed Jan 21 10:41:14 EST 2009 x86_64 x86_64 x86_64 GNU/Linux
I have created a number of network block devices that I would like to delete, but I have been unable to find any information to do this.
I am using Centos 5.6 and my kernel is 2.6.18-238.el5.
I have been searching the internet for two days now and have noticed some other UNIX systems do have utilities for deleting unwanted devices but nothing for linux.
I created these devices with the vmware supplied PERL script vmware-mount.pl which in turn calls mknod.
The commands would look like:
mknod /dev/nbd0 b 43 0
mknod /dev/nbd1 b 43 1
......
I have tried deleting them from /dev which works temporarily but they come back when I reload the nbd module i.e.
modprobe -r nbd
modprobe nbd
and also if I reboot.
There is a directory tree for each device under /sys/block and I'm guessing this is how /dev is getting repopulated. I cannot remove the directory trees from /sys/block. I get this when I try:
rm: cannot remove `nbd15/queue/iosched/slice_idle': Operation not permitted
rm: cannot remove `nbd15/queue/iosched/slice_async_rq': Operation not permitted
...... there are 25 lines like this ....
When I do a vgsan I see this:Reading all physical volumes. This may take a while...
