Allright, I bought a new dedicated box about two months ago. For most of the time, I have had major intermittent latency and downtime.Pings and traceroutes would always work, <70ms. However, all daemons would be inaccessible for periods of time spanning from 5 minutes to hours, at which point I would have the box rebooted and it would work again.After having hardware tests done numerous times, they kept saying it was software related. No logs showed problems.Finally, tonight a tech found that the network cable was frayed or something of that nature. "Noticed that your connection to the switch was exposed and replaced the cable"Would that create symptoms I've described above?
im not quite sure how to succintly say what is happening. the general idea is that my internet stopped working and I dont know why. I have a netbook that i am using while i am backpacking through asia. it has both ubuntu netbook ed, and winXP dual booting on it. out of the blue, i could not aquire an ip address through dhcp. This was true in both windows and linux, AND true while using either a wireless or wired connection. ok, that is odd, but not a big deal, i will just set the ip / subnet mask / gateway / dns manually. After doing this the computer reports properly connecting to the internet (did the same tests and got the same results in both nix and winxp), however I could not do anything on the internet. could not ping, nor do a dns lookup much less anything else.
scraching my head I looked around the internet for a solution and came across 'netsh int ip reset' this is a command I typed into the windows command line. I'm not sure what it does, but it worked so far as now
Can Cat5e RJ45 connector crimper be used for Cat 6 connector because I heard cat 6 connector is different from cat 5e connector and also same question for cable tester can cat5e cable tester be used for cat 6 cable?
Warning: NooB typing this. Two days ago I replaced an old version of Kubuntu with Squeeze. (This is not the computer/system I've written about in two recent threads.) Installation went smoothly, but one very early boot (I think the very first after installation) halted very early on, with:Waiting for /dev to be fully populated... [ 4.051267]ACPI: I/O resource 0000:00:1f.3 [0x1c00:0x1c1f] conflicts with ACPI region SMBI [0x1c00-0x1c0f]I stared at that for a very long time, used another computer to google for clues on what to do about it, couldn't find any text that I could understand -- I don't have a degree in anything computer-related, I'm just Joe Blow who wants to get things done on a computer without malware scares -- and eventually gave up and rebooted.
The reboot went well and I hoped there'd just been some kind of fluke. Just now, however, booting -- for perhaps the second or third time since the frozen mis-boot -- brought an elegant message telling me of a kernel failure and asking me if I wanted to inform whoever of it. (Yes, I responded.) The computer seems to be working fine: I haven't rebooted it since that error message, yet here I am browsing and posting away.Unlike this person, for example, I don't know what the hell I'm doing. (Well, I do know that he's using SuSE, I'm using Debian Squeeze, and they're not the same.)The computer's a circa-two-year-old laptop; I doubt that it's flaky because I there were no (visible) boot problems with Kubuntu just last week. I haven't installed anything other than from debian.org's squeeze repository. The mouse that's plugged in now isn't the same as the trackball plugged in yesterday, but that's the extent of any "hardware changes".If this computer fails to boot one time in four and at other times gives scary error messages that I can safely ignore -- well, I can live with that. But my guess is that it's more like an oil pressure warning light in a car: that I ignore this stuff at my peril.
how I could file share, or make the whole Hard Drive (HDD) accessible to another computer. The two other computers I have are a Toshiba Laptop with Ethernet and USB, and a iMac Intel with Firewire, USB, and Ethernet. Putting these to use along with:
Three Ethernet Cables Two Printer Peripheral USB Cables The Two Computers A 2GB Flash Drive
That is all I can think of right now. I do not want to use CDs. In a way, I would like to do a network boot. So, how do I get the whole HDD visible to the others computers (either/both) and be able to write to it? I want to put Xubuntu on it, and earse the rest of the Hard Drive. The computers getting this are the iMac G3s and the eMac G4. The eMac has 256MB RAM, 40GB HDD, and a 700MHz processor. Two iMacs have 128MB RAM, 40GB HDD, and a 600MHz Processor. The other iMac is the same as the rest but has a 500MHz processor.
I run 64 bit ubuntu 9.10. I recently rebooted my computer with a flash drive plugged into a USB port. My question is, could I have got a boot sector virus because of this? What are the symptoms of a boot sector infection? After the incident, I scanned the flash drive with clamav and it didn't detect any viruses. Also, in the BIOS, the hard drive is higher up in the boot sequence than USB mass storage drives. These two things suggest to me that a boot sector virus is improbable. But, recently, when I tried to boot into ubuntu, I got an error message saying that /dev/disk/uuid<some characters here> didn't exist.
Is this a symptom of a boot sector virus? So, I ended up re-installing ubuntu and I believe grub was written to the MBR. Will this have erased any boot sector viruses that were on my system? Can a boot-sector virus affect linux too? How can I check to see if I have a boot-sector infection? I also have windows xp on my computer. For some reason, windows xp isn't letting me install any updates, but this has been going on for since before the above incident with the flash drive and therefore I don't think that is due to a boot sector virus.
It feels like it is a keyboard problem because the symptoms always show after pressing a key.
In most instances, a line I am typing in "gedit" at the correct place in the text is unexpectedly continued a few lines downward even though no arrow key has been pressed. In another instance, I click "new thread" in Linuxquestions, a new window opens asking for a title, after entering the title I click "Click Here to Find Similar Threads", a new smaller window opens on top of the existing one and shows the existing options but as soon as I select (click on) one of these options, the main Linuxquestions window disappears and there is no option of "going back" to it and no "back" button to click.
If the keyboard needs cleaning, how do I do that? I found a few cleaning hints about separate keyboards but nothing about laptops.
I just got connected to Charter Cable Internet service a few days ago and I'm having a weird problem with my home network. Prior to this my network worked fine. On my network I have a desktop running Ubuntu 9.10/64 and Virtualbox with WinXP installed, an HTPC with Ubuntu 9.10/32 installed and a laptop dual booted with Ubuntu 9.10/32 and WinXP. The desktop and HTPC are hard wired to a wireless router and the laptop is wireless. The cable modem is hard wired to the router. I have samba installed and UFW is disabled. The problem is: with the cable modem turned off or on standby, all machines connect to each other and can transfer files, etc just fine but when I activate the cable modem all of the machines can connect to the Internet but the machines running Ubuntu can't connect to each other on the home network. If I boot the laptop into Windows, it can connect to the Linux machines just fine but if I boot it into Linux, it won't connect to the Linux machines but it can connect to the Internet and as far as the desktop, Ubuntu won't connect to the network but Windows running in the Virtualbox with bridged networking can connect to all of the machines.
I have a 2-floor house, with a single ethernet cable from the ground floor to the 1st. Downstair there is my ADSL modem, which is connected to the router upstair through this one cable. Now, I would like to have some more ethernet ports on the ground floor, but there's no room left to run another cable between the floors, so here's the big question: can I run both the modem-router connection and my regular LAN (which are on different subnets) through that one cable, with a switch at both ends?
To make it a little more clear, here is my present configuration
I am working on h/w device having linux kernel version 2.6.27 with busybox installed. I observed below problems while working on jffs2 image is flashed on the board.
1)When the board is powered-up with n/w cable is connected, it doesn't get IP address automatically, I have to use "/etc/init.d/networking restart" in init script(/etc/init.d/rcS) to get the IP address.(I am using dynamic addressing)
2)When the board is powered-up with n/w cable is unplugged and plugging-in once the device is started, I get "link up" message from the system, but still the IP is missing in eth0 interface.
I have udhcpc(v1.14.1) installed. Giving below commands manually, get the IP for device:
Code: ifdown eth0 /etc/init.d/networking restart but It is not pretty solution for me !
What I want is, the device should get IP address automatically once the n/w cable is plugged-in. (as we get in desktop m/c's). Am I missing some scripts or configuration parameters?
I normally use a cable to connect to the Internet, but I also use the wireless network regularly. So I'd like Ubuntu to automatically use the wired connection except when there isn't any.
I also have the unlock keyring problem (because of auto login and wireless Internet), does anyone know a solution to that problem? (It's quite disturbing to get that window each time you start the pc even if you aren't going to use wireless Internet)

I want to setup my Dell 1525 laptops to download DVR Recordings and Record Live TV with my Scientific Atlanta Explorer 8300HD Cable DVR.I purchased a USB "A to A" cable, but it states this cable cannot be used to connect PC to PC/Cable Box?Can I connect to the DVR directly and with what kind of cable (USB, S-Video, HDMI)?Do I have to use some kind of "Video Capture Box"?Can anyone point me in the right direction?
I can't get a certain harddrive out of its mounting (screws too tight) , but I want it connected to a different computer. Is it possible to have the harddrive's powercable connected to one computer, and its SATA cable connected to another computer's motherboard? (The powercable is too short to connect it to the other computer.)
Linux box could act as a router? I have one machine running ubuntu, another running windows 7, a cable modem and a switch. Is it posible to share the connection between both computers by making the linux box a "router"?
I'm having trouble connecting to the internet... I'm using Ubuntu 10.04 on a PC with Windows XP installed. When I click the little network icon at the top there's an option called "auto eth1" but when I click it, it just says "Wired Connection: Disconnected - you are now offline."
I am using ububntu 9.10,and have a cable modem internet connection. All I have is an ethernet cable given to me,and when plugged in a windows machine and fire a browser am redirected to default login page where i can login, but when i plug it into my linux machine,i cant get the same done. In network connections it doesnt shows my autoeth0, i have deleted my existing dsl settings(not autoeth0),made a new wired network,i doubt what should i put into MAC addrs field(i have put my machines mac given by lshw -c network.) What should I put in DHCP client id? Anyways when i click on network connections it says under my wired connections-device not configured properly.
I thought id give 11.04 a bash and i cant connect to internet via wifi i have a broadcom network adapter built into my hp530 laptop , and my network port is broken so cant use cable connection , so i thought id go back to 10.04 , guess wat i need to d/l the drivers again ... and again i have the same problem ? i have another laptop running win 7 , anyone know how i can get the drivers or what i can do ... ? its a broadcom BCM4311 802.11b/g
I have a Verizon wireless/wired router that I access the internet through. I have a desktop computer running Slackware 13.1 i386, but it is in a place where it would be impossible to run a network cable to. Would you buy a USB wireless card? Would it work with Linux? Is there another way I can get my computer networked that I am not thinking of?
I have a vista computer that is connected to a router via a ethernet cord. The router is connected to the internet.I have a computer installed with Debian that does not have a ethernet port in the back of it. Is there a way that I could connect my Debian computer to the internet through my vista?
At the outset I would like to tell everyone that I am still relatively a newbie in linux. I use a usb mobile broadband data card to connect to the internet, and I recently purchased another desktop for my wife. Both of us do not share any files, but I do not have a router and was wondering if I could share my connection with her using a crossover cable.I did a lot of Googling around and tried various different things, I even followed another thread in the same forum but the most that I have got is my network manager saying that connection has been established. I am however not able to see her computer under my windows network and don't know how to proceed.I don't know where I am going wrong, and considering that my knowledge of networking is at below basement level, I would really appreciate any help in this regard.
I ended up inheriting an IBM Intellistation Z Pro desktop with Red Hat 2.6.9-78.0.17.EL, that used to be part of a company network (hard IP, domain, etc). I'm trying to boot and connect to my home internet provider.With or without ethernet cable connected, the boot process seems to timeout on a number of steps (system logger, NFS Statd, automount5) and eventually get's stuck in NFS quotas.I started looking at /etc (in single user mode) and of course there are a bunch of files (hosts, resolv.conf, etc) with hard IPs, domains, etc.My questions are:- how hard is to change network setting to use soft IP and be able to connect to my provider
I have a laptop, and the wireless and cable worked fine for a while, but one day, for some odd reason, the wireless and network cable just stopped working. I'd connect to the web, and I would get output using "ifconfig" and the GUI wireless signal. When I hook up the wire, it detects it. However, no matter what I can't load any web pages. The wire does work in another house, and my windows partition utilizes these devices well. Any ideas?Additionally, I am able to log into my wireless router and change configurations, but that's about it :/.
I've got a Laptop with wireless broadband connection which needs to be connected to a desktop machine so that the internet connection could be shared. Both has got Ubuntu 9.1. I don't have a router or a switch. I just need direct connection with a cross over cable.
I have a wireless connection with static ip 192.168.10.150 to connect to Internet through a modem / router ADSL ip Lan 192.168.10.1. I connect with no problems. I have a wired network in the office 172.16.17.0/24 to work with the servers. the router is 172.16.17.1, my connection eth0 with static ip 172.16.17.150 work, but Internet by Internet nothing. If i disconnect the cable i have Internet from wireless. ?? What i have to do to ,to received internet by wireless and be connected ate same time to my wired network by eth0 too.
I recently installed the vt6656 wireless pci card that came with my zotac motherboard. I can associate with my ap and get an ip address successfully. When I disconnect my ethernet cable, however, my wireless interface stops responding (can't ping it). The box itself is in a place where I don't have a monitor connected to it so I cant see anything since my ssh session gets killed as soon as I disconnect the ethernet cable.
What would be the reason why the ehternet cable being unplugged, disconnects my wifi card as well? Does something get triggered? I did some testing with iptables, blocking the 8080 traffic to the wired interface, and noticed that the 8080 traffic also gets blocked to the wifi ip. I'm afraid that this never worked properly to begin with.
I am trying to run a cable from my wireless router over a 75ft cat6 cable to my bedroom. I don't get any connection on my end and I don't have any other ideas. I did setup a m0n0wall box just to try. I got the network led on my server to light up in my room but nothing more than that. Lastly, I tried adding a 5 port switch in my room and then connecting that to my server and nada.
I've been reading too much and understanding too little. What I have: Lucid laptop & desktop. Both have ethernet > hub > internet. What I want: connect them directly by the serial ports so the laptop can access the desktop's drives, and the desktop can be retired from the internet. I've got an old DB-25 null-modem, last used for multiplayer Doom. The laptop's dock has DB-9, so the connections is desktop > null-modem > Belkin DB-25 - DB-9 cable > laptop.
I had hoped this post would get me somewhere:[URL].. No such luck. When I ping 'grin.local', the connection is through the internet. If I disconnect the hub, i cannot ping.
Dunno if there's something more I should do to enable serial connection in Lucid, or if my null-modem is no longer good. I'm also rather curious how "grin.local" manages a connection through my ISP's system. These are DHCP. Shouldn't that have required the full numerical IP?
(It's nothing to do with the hub. Checked that by connecting a third box to the hub. My ISP only hands out two IP. I couldn't ping the third box.)
I'm trying to get my Ubunutu and OSX systems to connected via a cat5 cable to transfer some large files around very quickly. Now i know normally this would require a crossover cable as it's a direct connection but the macbook/OSX can handle changing the wires round to make it work like a crossover cable as I've done it before. However the macbook creates a self-assigned IP or as I've tried I've set it to : IP:10.10.0.1 Subnet: 255.255.255.0
Then I've setup the Ubuntu system both through the System>Admin>Network panel as: IP:10.10.0.2 Subnet: 255.255.255.0 and my /etc/network/interfaces file is the same; #lines added to get static crossover cable working auto lo iface eth0 inet static address 10.10.0.2 netmask 255.255.255.0
Yet when I run ifconfig in the terminal eth0 isn't present Code: htpc:~$ ifconfig lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:912 errors:0 dropped:0 overruns:0 frame:0 TX packets:912 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:371613 (371.6 KB) TX bytes:371613 (371.6 KB)
htpc:~$ ifconfig eth0 eth0 Link encap:Ethernet HWaddr 90:fb:a6:e4:c0:b0 BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:23 Base address:0xe000
Also even when I try and ping 10.10.0.2 either from my OS X or the actually Ubunutu machine all I get is: Code: ping 10.10.0.1 PING 10.10.0.1 (10.10.0.1): 56 data bytes Request timeout for icmp_seq 0 Request timeout for icmp_seq 1 Request timeout for icmp_seq 2 Request timeout for icmp_seq 3
Yet the Ubunutu machine is also connected to Wifi and when I ping it's own address I get the expected response. To me it just seems like eth0 isn't being recognised somwhere or it's not turned on yet I can't seem to find any toggles or settings for it anywhere. Further more if I check >System>Admin>Network Tools the IP for eth0 is 0.0.0.0. What could be going wrong and why no IP set correctly?
