Debian Hardware :: Don't Get Disconnected But After It Freezes Can't Even Reach The Router By Its Ip?
Apr 18, 2011
For some time my wireless was working perfectly but now if I do something that uses more bandwidth - the connection freezes. Takes a minute when using torrents @400kb/s. Wireless starts to work for some time if I reconnect to router but stops again if the load is same. I don't get disconnected but after it freezes I can't even reach the router by its ip. Any ideas?02:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)

As the title say, I'm having this odd problem, consistently, if I disconnect the USB keyboard from the box, it hangs after initializing md0 (raid of 10 sata disks).. The cursor blinks, but it never gets further, I've had it hanging like that for a day (I started the box before I went to school, and when I got home, I found that it never booted completely)
If I connect the keyboard, the box boots fine..

This has probably been beaten to death, but I can't find anything that fits my exact situation (maybe I'm using the wrong keywords, sorry).
Server:
eth0 - external NIC, DHCP IP from ISP
eth1 - internal NIC, static 192.168.0.1
DHCP running on eth1
IPTABLES set up to masquerade on eth0
I have a computer connected up via server's eth1. It's IP is 192.168.0.201 (/etc/init.d/networking restart) gives me a DHCPOFFER and everything, so DHCP seems to be working fine.
Server:
can access internet I can ssh into 192.168.0.201 (even though it seems to take longer than usual)
192.168.0.201:
can ping server (well duh, I ssh'ed in from the server) cannot access internet for DNS on the internal NAT I'm using the same DNS servers as the router, so the server's
resolv.conf:
nameserver 69.169.190.211
nameserver 208.72.160.67

I'm currently moving a lot (200G) from an external hard drive on one pc to an external hard drive on a laptop and I'm using scp to do it. I have a bt home hub 2.0 and as luck would have it my laptop keeps getting disconnected from the network.I'm worried that this will result in data loss or corruption as this has happened about 5 or 6t times just that I was aware of.

Whenever I disconnect the LAN cable from my Linux box or reset the router the IP doesn't seem to get renewed and so I'm unable to SSH into it or connected to the webservices it is running.When it boots up it gets an IP fine from DHCP on the router but once the system is up and something changes like the router reboots or cable is disconnected, then this is when the problem occurs.sometimes if you go back to the actual Linux box in my loft and open a terminal and runcd /etc/init.d/./networking restartthis will cause it to get a new IP from the DHCP server but this isn't very convinient and a bit haphazard.

How to enable wifi? I downloaded and installed Debian 6.00 and as I couldn't get online with my Tenda USB Wireless Adapter. I downloaded Debian 6.00 again, this time the CD Net Install version with Firmware included. However, the added firmware version of Debian does not find my wireless either. My wireless adopter is shown as Bus 001 Device 003: ID 148f:3072 Ralink Technology, Corp. RT3072 Wireless Adapter. There is a Network Icon in the Panel which when clicked shows "Create New Wireless Network". I have put in my ISP related network and my password and rebooted, but all I get is the message on my desktop:
"The Network Connection has been disconnected."
That isn't very polite, is it? Who has disconnected it and why remains a mystery to everyone except the culprit(s). I think I must have missed a basic step in the Wifi Enabling process. I checked the Use Permissions and everything is fine there, as User I have permissions to use modems and do networking and so forth. Also I should like to try "modprobe" but I see the package isn't in Synaptic Package Manager.

I'm trying to give some windows users a permanent connection to a samba share behind a firewall over the public Internet. I know I can give them access with something like winscp (which they have done) but really I'd like to do it with a VPN so it seems seamless to the user. However I have no idea how to set up the server to support this and am finding the documentation a bit confusing. The samba share is on a Debian box and the firwewall is a Linksys WRT54GL.

I did a search and found this link however I remember this being an issue almost two years ago when I installed Debian with a GUI. I have always used it for a server so I never realized this was still an issue until I got my new PC today and went to load Debian / Gnome on it. It showed I was disconnected however I was able to browse the web fine. It appears that so many people have complained about this problem andI am trying to understand if there is a work around and a fix in the near future

I'm trying to get some photos off a Canon Powershot SX110IS that uses an SD card (right now there is a Gigaware 4GB one in it) but this computer does not have an SD card input, so I am trying to mount the device through USB. This has worked with a handful of other cameras I've used in the past.
When I connect the camera to the computer and power it on, I get
usb 1-5: USB disconnect, address 7
usb 1-5: new high speed USB device using ehci_hcd and address 8
usb 1-5: New USB device found, idVendor=04a9, idProduct=3192

usb 1-5: Product: Canon Digital Camera
usb 1-5: Manufacturer: Canon Inc.
usb 1-5: SerialNumber: DA9C3D5C2D7F4E3EA806AA70BCDF3E28
So the kernel is at least aware of it. I tried letting thunar mount it, but it complains
thunar-volman: No property info.capabilities on device with
id /org/freedesktop/Hal/devices/usb_device_4a9_3192_DA9C3D5C2D7F4E3EA806AA70BCDF3E28.
I also tried letting dolphin automount it (yuck), but didn't get any messages about it. I checked the fdisk output and there was no ~4GB device, so I'm not sure that I can mount it manually.

Unfortunately, when I try to install Debian off the DVD, the wireless gets disconnected right when it tells me to choose my method of connecting to the net. It then gives me three choices of connecting - wired, unknown, and wireless. I must be missing something, because when I choose wireless, it says it fails, and cannot find anything to connect to. I input the SSID and password manually and it says its not there. So I quit the install and go back to the desktop and reconnect no problems.

I'm configuring a debian computer to act as a router for my home network. I want to split my home network into two parts and define different firewall rules for these parts. I also want to use dhcp to make sure every time a computer logs in it gets the same ip but is still able to log in somewhere else. The biggest problem now is that I have to make some functions able to someone that has never worked with linux before.
I've worked with software routers like pfsense before and I would like a similar web frontend to this. Does anyone know if there is such a piece of software? I'm not using pfsense itself because I don't want to virtualize it and I need some things like the software raid5 and some htpc software I don't want to try to get working on pfsense. I've previously used webmin untill it was hacked because of an exploit in it so I preferably don't want to use that one. I've been working with the dd-wrt software and something like this would do the trick perfectly!

Because of the configuration of my house, I need two routers.I have a DLink ADSL router as my main router and the Belkin N1 as my repeater.I have set up the IP address in the Belkin to be 10.1.1.10 - my DLink is 10.1.1.1. I have disable the dhcp in the Belkin and set the DNS as ISP provided. [URL]..I have set the channel to 11 and in the Ubuntu Network Manger I have set the IPV4 to Link Local Only. I can see the Belkin and connect with my PC.but it will not take me through to the internet.

I want to set up a Linux box as a wireless router to replace our existing Netgear WNR1000 router, as I believe the Netgear does not support the coming IPv6 protocol. Unfortunately, it is not flashable with OpenWRT or DD-WRT presently.
As we have Comcast, our cable modem acts as a dumb modem according to the customer support guy I talked to, and our router is the one that asks for the IP address from DHCP. Thus, when Comcast switches over to IPv6, I don't believe my existing router would work, correct?
My idea is to take a Linux box and put two NICs and a wireless adapter in it, using IPCop or Smoothwall to set up a router. I could then enable IPv6 support for when we have IPv6 with Comcast. Is that possible? Would there be a way to get BIND to hand out private IP addresses in the same subnet on the both the LAN NIC and the wireless card?

I'm running stock Debian 8.2 with GNOME DE on an Acer ES1-512 series laptop. Whenever I attempt to go into suspend, either by closing the laptop lid or holding ALT when clicking the power button in the top-left system menu on the desktop, my laptop briefly flashes the default GNOME lock screen, fades to black, and then hangs there. Usually, when my laptop would actually suspend, the power indicator light would change from blue to orange and slowly fade in and out. However, now it just sits on blue. There is no way to re-awaken the laptop from this state, and I have to force shutdown by holding the power button.

This usually took place when I switch back to console from X (Ctrl+Alt+F1).After I start typing in the console, the characters started showing up one by one slowly and more slowly. Finially the console was completely frozen before all the characters were able to show up. This took place in less than 5 seconds. And I couldn't switched back to X either.Sometimes this happened even when I didn't log into X

I have a desktop PC running Ubuntu 9.10 and Windows 7, and a Eee PC 701 laptop running EasyPeasy Ubuntu 9.04. I'd like to connect the desktop to the laptop with a wired connection (eth0), then the laptop to my ADSL router using wireless (ath0).
I have a crossover ethernet cable (I bought on ebay). I have set up my laptop with a static IP address on my LAN and it uses OpenDNS.
I have added this to /etc/sysctl.conf on the laptop:
net.ipv4.ip_forward=1
Then I tried this on the laptop:
sudo iptables --table nat --append POSTROUTING --out-interface ath0 -j MASQUERADE
sudo iptables --append FORWARD --in-interface eth0 -j ACCEPT
This is a variation on what I found on other sites describing how to set up a router. I don't understand iptables very well, but I gather that the above two lines should set up forwarding so that traffic from my router to the laptop will be forwarded to the desktop, and vice versa.
But this doesn't work. The connection doesn't even establish between the laptop and the desktop.

I'm having trouble getting my network set up the way that I want it/had it. You see, when I first set up my network, I just had my cable modem going directly to my standard wired router (A D-Link DI-604), which had DHCP,and was connected to all of the computers on my network. I had one switch hooked up to one of the ports of the router, but this was a regular switch, and it would not try to assign IP addresses, it would just pass through the DHCP info as I wanted.
Now however, my network setup has changed. My room mate and I both got laptops, and we decided that we wanted to have wireless access so we didn't have to constantly plug in to the router.
Now my network is set up like this: The modem is hooked up to the router(DI-604), which is hooked up on the LAN side to our computers, our switch (which is hooked up to 3 more computers), and to a wireless router card (A Gigabyte GN-BC01).
The wireless router card has two jacks for ethernet. One for WAN, and one for LAN. The LAN side we have plugged only into the computer in which the card is installed.
Now the problem is this: The wireless router card comes with DHCP by default, and it's assigning addresses to the laptops and to the computer hat it's in, and worse, the IP addresses are on a different subnet than that of the main dlink router. The Main (dlink) router assigns addresses from 192.168.0.1 (itself) to 192.168.0.254, while the wireless router card assigns addresses from 192.168.1.1 to 192.168.1.254 (itself).
Because of this, I cannot access services on the wireless network from my wired network or vice versa. The first thing I tried was setting the card to assign addresses from 192.168.0.12 to 192.168.0.253, however it just said "internal error" when I tried to do this. I decided that this may be because it sees that it was being assigned an address on it's WAN side on the same subnet. So the next thing I tried was disabling DHCP and setting the "LAN IP Address" to 192.168.0.12, hoping that the DHCP would just go through the card, like a switch. I would have set the LAN IP address to be assigned by DHCP, but this was not an option, so I decided that'd be the best thing to set it to.
Once again however, setting the LAN ip address to an address on the same subnet as that of the IP assigned to it's WAN side caused it to report an "internal error". I verified that this was the issue by setting the LAN address to several other private IP addresses to test (I.E. 10.0.0.1, 192.168.3.1, 192.168.5.12).
My question then really is: How do I set up both routers so that I can access services and computers from each network from the other network. Should I set them with different subnets and set the gateway on the wireless network to the main router? To the wireless router card? Should I put them on the same subnet? Will it know how to communicate?

I wonder what is your opinion about the best method for using an ADSL modem. Router or bridge? I did read some articles that say "that the bridge mode gives you more stability and has higher speed". Is that true?
Furthermore, you suggest any alternative to "pppoeconf"? I've been getting this errors ( in the plog), related to "PAD packet loss" and also errors in "PPPOE Discovery", even when I am connected. When this things starts to show up on the log, my connection "pauses" for some seconds. I do not feel very safe with this program.

I've just bought a Linksys WRT610N router and I ran through various problems during the configuration, that brought some questions.Here is what I did to configure it (following the short manual that I got with the router)1. plugged the router in my modem and in my computer via ethernet cables2. entered its IP address (given on the manual) on my browser and logged in with the factory login3. changed the login passwordAfter this the problems that I have encountered are that:I set up the administration of the router to be disabled via wireless and enabled locally via https, but when saving those settings I either lost the connection (the browser telling me the server was not accessible) or asked confirm a security certificate after being (logically) redirected to the https version of the administration pageafter trying to loggin again, I wasn't able to login via https but only via http even if after logging those parameters were still as I set them (wireless administrative login disabled and local administrative login enabled only via https)
via https when getting something else than "the server is not responding or could be too busy", I was prompted the untrusted connection site, saying that"192.168.1.1 uses an invalid security certificate.The certificate is not trusted because it is self-signed.The certificate is only valid for Linksys.The certificate expired on 01/01/71 01:21. The current time is 19/04/11 22:56.(Error code:sec_error_expired_issuer_certificate)"I noticed that after loosing the connection and not being able to reach the router either with http or https, the only way I was then able to reconnect to it was to go into (I am using firefox 4 on squeeze) edit > preferences > advanced > encryption > view certificates > servers and delete the linksys certificate

I am trying to get more control of my small office network. It consists of several windows workstations, a debian box, and a ZyXEL P-660HW-D1 router, Right now, the only way to reach the debian box from other computers is to type in its ip address.
The goal is to be able to reach the box by just typing ://debianBox into my browser, though ideally I want to set it up to be something like ://debianBox.officenet, and to also reach other people's computers by typing ://mattBox.officenet and ://fredBox.officenet
The Zyxel router has a LAN page with a DHCP Setup tab with fields setup like so In the past I was able to mange this using an Orange router, but now I have to use the ZyXel.
So I installed dnsmasq on the debianBox, but I do not know how to configure it to get the results. I want and still get internet fromthe Zyxel router.
In the etc/hosts file of the debian box I added 192.168.69.15 debianBox, and for testing on my windows machine I set the primary dns entry of the Ip4 connection to 192.168.69.15 as well, but typing ://debianBox in my browser still gives me not found.
