CentOS 5 Networking :: E1000e Driver And 80003ES2LAN Nic Dropping Connections?
Apr 7, 2009
After doing a clean base install of CentOS 5.3 on a test server, I started having problems with network disconnects. While SSH into the box, I would be intermittently disconnected from the SSH session. At first I thought it was my workstation, but after running ping tests from multiple machines on the network to the test box, it became apparent that the test box was dropping packets. When I lose my SSH connection, the pings also start timing out, for a few seconds, then start again. I increased the console logging and I can see when the ethernet port goes up and down when I physically disconnect the cable, but it does not go down or lose link when the disconnects occur. I changed the NIC ports being used and had the same result. I tried with a different switch with same result. I reinstalled CentOS 5.2 and the problem went away.
Upon further investigation, I found that CentOS 5.2 is using the e1000 driver for my NICs and CentOS 5.3 is using the e1000e driver. I resinstalled CentOS 5.3, and tried using the e1000 driver instead of the e1000e but it no longer detects my NIC's... apparently they moved the support from e1000 to e1000e. I have spent the last 3 days googleing for info on this problem and have not found a solution. Any recommendations? Should I submit a bug report?

Here is the layout of my network:My cable modem plugs into eth0 on my ubuntu server which acts as a firewall (shorewall) and dhcp server to my lan. A dd-wrt access point is plugged into eth1 and then a bridge connecting my xbox360 and another bridge connecting a desktop computer.Everything works pretty well, except a few times a day, my network will just shut down. The wireless on my macbook and my wife's laptop will just shut down, and if my xbox is running, it will lose connectivity. It will be down for maybe a minute or two, and then come back up like nothing ever happened.I never had this problem when I had just a dd-wrt router running everything instead of my server.When I ssh into my server afterwards and run dmesg, this is what I will get:
Code:
[398598.251548] martian source 169.254.1.255 from 169.254.1.33, on dev eth1

I just built some machines with the Intel 82574L gigabit ethernet chip, loaded Fedora 14, and discovered a problem with the e1000e driver dying after a few minutes. A little time spent perusing the web told me that the same driver had problems in Fedora 12 and Fedora 13 as well. Congrats to Fedora for the hat trick.As of kernel 2.6.35.10-74.fc14.x86_64, e1000e driver 1.0.2-k4 still had bugs.[URL]

Our school has a small 3-computer lab in the preschool department where the kids come in and simply use Firefox to access some educational websites. Due to logistics in the building they're in we had to go with a wireless solution in the following setup:
- Apple Airport Extreme WAP
- 3 HP DX2200 desktops running Ubuntu 10.10
- 3 Trendnet TEW-664UB USB wifi chips
All was running great until we got the computers installed on site and now they are constantly dropping the wifi connection if they are even able to connect at all (which is highly hit or miss).
10.10 picked up the USB wifi card as soon as we plugged them in and showed the available networks, but actually obtaining and keeping connections is a nightmare at the point. The computers are in very close proximity to each other (only about 2-3 feet between computers) and the WAP is in the next room (other computers and mobile devices are able to connect to the WAP with full signal from the same room/location). Thats about all the detail I have off the top of my head, could this be an interference issue with the wifi cards or does this sound like an Ubunutu issue? Again we have had multiple other devices in that room all able to connect seamlessly.

I ran into a problem that seems to be related to: [URL] with an HP Desktop. The desktop has a Intel 82567LM-3 on board gigabit ethernet adapter which on a fresh install of 11.3 would not operate properly. The e1000e driver was properly detected however on loading, the ethernet interface was never initialized. My solution was to get the latest e1000e driver from intel.com: Network Adapter Driver for PCI-E Gigabit Network Connections under Linux*

Here's the situation: I've got an eee pc 901 running Ubuntu 9.10 netbook remix. I'm using it to connect to a WPA-encrypted wireless network on a WRT54GL running dd-wrt. It mostly connects and works ok, but sometimes it just stops working for no apparent reason (the netbook still shows itself as connected), but you can't get anywhere until you manually disconnect and reconnect. Other times, it will drop the connection, and then quickly reconnect (or sometimes not). Obviously, this behavior is pretty irritating. At first I thought the problem was with the router, but I checked the logs there and they all seem fine, and other computers on the same router don't have this problem. Looking at "dmesg | tail" on my netbook, I see a lot of instances of the following error, which I'm thinking is probably the problem:
Code:
[11137.762233] ERROR!!! RTMPCancelTimer failed, Timer hasn't been initialize!
[11142.872797] ===>rt_ioctl_giwscan. 4(4) BSS returned, data->length = 440
[11152.883274] ===>rt_ioctl_giwscan. 5(5) BSS returned, data->length = 556

[11163.952056] ERROR!!! RTMPCancelTimer failed, Timer hasn't been initialize!
I searched for that error message and I found this Ubuntu bug report: [URL] that describes symptoms that match mine. In that report, a poster mentions that he compiled and installed a new version of the wireless driver from the Ralink website, and it fixed his problem. Do you think installing a new driver would be good? Or has that updated driver already been added to the kernel since that bug report was filed? I've never compiled a kernel module before.
One other thing, I also see repeated instances of these lines (or similar ones) in dmesg, which look like they could be related.

I was having trouble with my wireless connection, it was dropping every 5 minutes or so after upgrading to 10.04 and ran across a thread where someone recommended entering
Code:
sudo apt-get install linux-backports-modules-wireless-lucid-generic
After entering the command I have lost all ability to even use my wireless ability even if it was for 5 minutes. Now I am using a different kernel, internet still drops every 5 minutes, but would love to get my internet up and running again.
I am using a Dell Studio XPS Laptop
Code:

I did a clean install of OpenSuse 11.3 a couple of weekends back. Everything is working great except the SSH server.Once I installed ssh, it appears to accept my connection, allows me to log in, and then freezes Putty, not allowing me to type anything into the terminal.If I wait several minutes, I'll get a message saying that the connection was closed. After that, the server won't accept connections.Sometimes it'll start accepting connections again, but after a while, the connection will close on its own. Other times, I will be unable to get a connection until I restart the server.If you guys needs any more information, please let me know. What could be causing this odd behavior?

As soon as i'm starting to copy a large file enough file (>700Mb) to my ubuntu box (connected to an Asus router via wifi) from a Windows 7 client (connected to router via ethernet cable) i get a dramatic drop in speed. upload starts at 1,0Mb/sec with a ping to ubuntu box at <1ms, and in 2 minutes it drops to 200kb/sec with a ping of over 1000ms! The ping increases with every second in a linear progression.
To exlude router as a possible problem copying to a windows 7 notebook connected to router via wifi results in an average of 2,7Mb/sec with an average ping of 150ms.
MB Model: Asus P5B Deluxe wifi
OS: Ubuntu Server 9.10 + desktop installed

I am trying to use a rig with Gigabyte GA-880GA-UD3H mother board and Intel 82574L based NIC (EXPI9301CTBLK) under CentOS 5.5. Unfortunately I have issue with the NIC - during boot it fails to initialize:
[Code]....
I receive the same result with the original e1000e driver from the distribution, the latest elrepo driver and the latest driver from Intel site (as seen in the example). I have tried also 2.6.37 kernel version - with the same result. The adapter however works fine under Windows (MiniXP from Hiren's BootCD) and with Ubuntu 10.10 LiveCD.

I am struggling to install RHEL 5 in one Hp Compaq dc7900 machine. My network is not coming up with a message e1000e device eth0 does not seem to be present. lspci givens following message
00:19.0 Ethernet controller: Intel Corporation Unknown device 10de (rev 02)
Subsystem: Hewlett-Packard Company Unknown device 3035
Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B-

I could see /etc/modprobe.conf has a line "alias etho e1000e" present. In fact another machine dc7900, installed with Fedora Core 10, detects the card with e1000e as the module.

I wrote a small hello world type of character device driver. When I type echo -n "abcdef" > /dev/bond and do a cat /dev/bond then only last "f" of above input abcdef is displayed rest nothing is displayed. I asked this question earlier and some people suggested me some modifications I have done and experimented all that but I am unable to catch the error.
Here is the code

I'm developing a simple TCP server. 99% of incoming connections terminate correctly and the sockets disappear from netstat outputHowever, a few connections hang around for indefinitely in the FIN_WAIT2 state. Now, I know that the clients in this case are misbehaving by not sending a FIN,ACK to close the connection. However, regardless of client behaviour, the connections should only remain in this state for a maximum of 60 seconds (set globally by /proc/sys/net/ipv4/tcp_fin_timeout)

This is on Centos 5.3 by the way..... I had a DVD and, well, just wanted to test some things.. I'm aware that this is not the latest release.
And, by the way (I just read an earlier post) I've added the username and password with which I'm trying to login (..hello?).
I'm at work and I don't have a copy of my Vsftpd configuration file (don't wanna edit this whole thing - actually there is a copy, below). I've used Slackware for years and never had any issues with Vsftpd - it just works. I am trying Centos because I need help with upgrading my mail server (qmail) and there's not much help for Slackware users. Also, I used to run RHEL3 and had vsftpd working fine (had to copy some file to /etc/pam.d) but it worked famously. I compiled all my web server stuff (just don't like these default things where I have no idea how things are integrated) and I'm hung up on - of all things - vsftpd.
Anyway....When I try to log into my ftp server I get "KERBEROS_V4 rejected as an authentication type" and only the anonymous account works. Any other logins produce an error (incorrect login - see ya' later). I have SE Linux and the firewall OFF. I don't recall the directive, precisely, but my vsftpd.conf file is set allow local users to connect. I installed with yum and it added some lines at the bottom (one was about a user list and the other was about PAM). I've got a chroot list and a user list although it's not clear to me precisely where the user list should be placed. I actually uninstalled the RPM and compiled, too. I've done everything but call an exorcist. And I've found tons of posts regarding this on the net and none of the fixes worked. Man - on slackware you type "make" and "make install" (I build it with tcp_wrappers) and you're off to the races.
Actually - I did upload the vsftpd.conf file to work (where I'm at, now). Minus lines that were commented out it looks like this:
Could it, possibly, be something about how I am adding the user, the shell type, etc? I know that in Redhat I used to type "/usr/sbin/useradd -d /home/someuser joe". I've done it that way and I've also done it like so: "useradd -d /home/schmoe -s /bin/bash schmoe".

i've got a select based application that wants to support a large number of mostly idle connections. the code is java and works on windows, suse enterprise linux, mac os x. it does not work on centos 5.5 (32-bit, 2.6.18 kernel, 1G of memory).
i've read and followed the directions in various articles about tuning linux for large numbers of connections (including the C10K problem), and gotten the number of sockets up to 3200.
these didn't make any apparent difference:
[URL]
on windows, i can get up to around 78,000.
on suse enterprise linux (a few years ago), i got up to 90,000. that's where i got bored and stopped.
on my mac laptop with os x (snow leopard), i got up to 10,500.
i have used ulimit -n 10240
my current goal is 10k sockets.
the test is that i'm opening one socket at a time until it fails. when it fails, many of the sockets which have already been opened also fail, in one giant cascade. sounds like a buffer / memory problem.
each group of 64 sockets gets a thread to manage select calls for them. thus i'm only using around 61 threads total when it fails.

I have just installed a fresh copy of CentOS 5.3 and from the get-go, the NIC started dropping packets like crazy. I even closed the port on the switch,. moved the cable to a different port,. All yield the same "dropping packets" behavior. Zero on the errors, just dropping packets. Should I stick a diff nic instead?

We have a process whereby we used a rescuecd and partimage to take a snapshot image of one of our laptops, then we use it to lay down the snapshot on other laptops as requests for them come in. The image was created on an HP (Compaq) 8510, and has always worked laying it down on other 8510s.
So now we get a stack of HP Elitebook 8530s, which will be our new standard. So we're testing how laying down the old 8510 image will work laying it down on the new 8530s. As far as putting down the filesystem image, all looks great. However, we'reseeing the msg "bringing up interface eth0: e1000 device eth0 does not seem to be present, delaying initialization." Which I believe is his way of telling me "sorry, whatever driver you've given me can't drive this ethernet card." And needless to say, ifconfig -a doesn't even show anything on eth0.
I'm thinking (hoping) that if we get and install the proper driver to drive the ethernet adapter that's onboard the 8530, we can get this guy some network connectivity, at which point the rest of the tweaks we need to make should be comparatively easy.
how to get the proper driver and b) how to install it? Keep in mind this machine has no connectivity, so I'll have to sneakernet it over from my laptop to the machine.

I have a:
# lspci | grep Ether
02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 03)
Looks like the r8169 module that gets loaded is not a valid choice for this chipset. The main error that I see is:
r8169: eth0: link down
ADDRCONF(NETDEV_UP): eth0: link is not ready
I have verified the cable and it's good the windows machine next door is fine using it without packet loss.
The system is a HP Desktop, just CentOS 5.5 loaded on it (base, with no updates).

I'm using Ubuntu 9.04 64 bit on an Asus laptop and the wireless connection disconnects randomly for a while and keeps searching for the signal. When it finds it I have to put in my WEP key again to get it to connect sometimes only once or sometimes 2 or 3 times. This is getting quite annoying.

This is weird. I will be working on the internet with several tabs open and all of a sudden the pages won't update. I can't go anywhere - it's like I lost the connection. I am also downloading bittorrents with uTorrent running with WIne and that doesn't seem to be affected. I also have gPodder and I tried to update podcasts with that and it also hangs up as if it can't connect. The only way I have been able to solve this has been to reboot (which I just did).

Having major wireless issues with Linux. I have DSL and had a Westell router/modem combo and my wireless would stay up for no more than 15 mins at a time even while idle, and in order to get wireless back I have to reboot and then I can get another 5-15 mins of wireless before it drops. When it drops it prompts me for my wep key and wont accept it yet if I reboot it catches the wireless right away for a very short period. So I go out today and spend over $100 bucks on a Netgear dgn2000 thinking it would fix the problem... Nope I am still in the same boat as I was with the Westell.
I am not seeing my router model listed under the wiki link sticky.. (Edit) thought I installed ndiswrapper, it was it was in my downloads anyway I can't install it I get the following error (Not a valid driver .inf file.)I have tried 3 distros and have the same problem. I went to Netgears site in search of Linux drivers but all I found was the firmware updates. Could some one please shed some light on what I need to do to get up and running?This is a new laptop and I am pretty annoyed with myself for formatting it out of the box rather than reading up a bit more about Linux (been using for one month).I don't understand it Ubuntu 10.9 ran wireless perfect on my older system, (full install) and I have no trouble with my lap top that is running Windows.I really hope to get this resolved I really enjoy Linux and I don't want this to be the one handicap which would force me back to Windows, that would be very upsetting

Lately I have been using my window's partition due to the fact that 10.04 drops my wireless signal every 5-10 minutes, but today I downloaded the new updates and that seems to have fix the issue with the dropping of the wireless connection. Now the only problem is the internet is so slow when trying to go to webpages it times out. I have opened up firefox gone to about:config and changed the necessary lines, but still dreadfully slow.
