Ubuntu Networking :: WiFi Dropping And Dropping Speed

Feb 25, 2010

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
Wifi configured via GUI

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?

CentOS 5 Server :: Login Via SSH Takes Over A Minute?

Nov 12, 2010

Just started to encounter this problem recently: after entering a valid password for a given user during an SSH login, it takes at least one minute to get to a prompt. It usually takes only a second to check the password and drop me to a prompt.

I haven't had this problem before - it seems to have started this week. Only thing I've done this week is run updates. Has anyone encountered this problem recently? Any ideas or fixes that may help solve this? Server info: not exposed to the Internet, only running SSH, fully patched version of CentOS 5.5 x86_64.

CentOS 5 Hardware :: NIC Dropping Packets - Zero On Errors

Aug 2, 2009

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?

Jan 25, 2010

I am new to linux and WAS a window user. boy am i glad i switched, but still have lots to learn. Any who, currently i am working on a server for some residents at my current job. I have DNS and everything setup right and it is working. Samba on the other hand is configured right but it keeps shutting down after about a minute. it says "Dead". Ill restart the service(rcsmb start), and keep checking the status, and after about a minute it shuts down again. I have done a restart, double checked my configurations and still cant find why this is happening. (config file somewhere?)

Now since im new, im not sure what info any of you would need to help me out, so please chime in, if there is a specific file or info you need to know, please let me know and ill try my best to get it.

CentOS 5 Networking :: Can Use Samba Share But Cannot Mount It

May 27, 2010

I am trying to mount a file server directory on a client machine. I tried using NFS, but could not mount the share on the client. Several respobses were given to a post on this problem. but I still was not able mount the NFS share. I decided to try instead to mount the directory as a Samba share because I can already access it using Samba from windows, or from KDE or Gnome using smb://fileserver as a desktop location icon URL. When I try to mount the Samba share I get error messages that nearly identical those that occurred with NFS. . Here are some of the setup parameters

CentOS 5.4 on client and server behind a D-Link router
server IP: 192.168.0.44 (can ping it client)
client IP: 192.168.0.101 (can ping from server)

[code]....

This is the only error message that these commands have produced in the messages log, secure log or smbd log for either machine. My immediate goal is to set up the simplest possible local mount that will allow Grsync to backup to the file server.

CentOS 5 Networking :: Windows Permissions On Samba Share?

Apr 30, 2009

I have set up a Samba share via my CentOS 5 server (the samba share is actually a mounted filesystem, not local machine space). I have been successful in adding permissions for my windows users within the smb.conf, but have an additional need that I cannot figure out. I would like for my Windows administrators to be able to create folders and assign permissions from their machines (and their Windows GUI). Ultimately I need the folders on the Samba share to behave correctly when Windows group permissions are applied by these administrators.

When the folders are created, the "Everyone" identity cannot be deleted and sometimes "Creator Owner" or "Creater Group" show up. I have seen several threads start down this path, but haven't seen a definite answer (I may have just missed it!).

CentOS 5 Networking :: Samba Share Access Restriction?

Apr 29, 2010

cannot restrict share access to a single user. I've played with the security and valid users options in the smb.conf and I can get it to mount if I remove the valid users option, but this does not provide the access restriction I need. I also left it open and tried making the folder permissions rwx for backupadmin only and that didn't work. I'm using a credentials file which I include below, but I've tried manually entering them in the command too.

[root@aaphst02 /]# mount -t cifs //aapsan01/aapxen01 /mnt/aapxen01 --verbose -o credentials=/root/smbcreds
mount.cifs kernel mount options: unc=//aapsan01aapxen01,ip=10.0.1.34,user=backupadmin,ver=1,rw,credentials=/root/smbcreds,pass=********

CentOS 5 Networking :: Get Samba To Share Files From Ntfs Drive?

Jun 12, 2009

The file permissions on the folder are RW for user,group and world.(umask=0000) My main problem is with SELinux, I've tried to audit2allow and that seemed to work, all I had to do then was chcon the directory and files to type samba_share_t but the tool fails with Operation Not Supported. Am I to assume you simply cannot share files from a mounted ntfs drive under SELinux? Because I've just spent 2 hours trying and I've just about ready to just give up and just go back to windows when I need to share those folders. There's no way i can copy the folder contents to my Linux partition, far too big for that. Has anyone EVER been able to do this? Do I have to disable SELinux to do it?

CentOS 5 Networking :: Samba Password Infinate Loop From Windows

Nov 12, 2009

I have just started a job as an IT tech, and have inherited a linux server running CEntOS 5.3 -- I have some experiance with linux, but am a little at sea. I'm using Webmin 1.490.The main use of the server is to samba share file space to windows clients, running XP.Everyone can happily connect to their home share, however the other shares have problems. One of the shares "staff" fails intermittently (to some staff members) and some of the other shares fail always.

The failure is that when a user tries to connect to the share, it pops up a username and password dialog (even if they just successfully viewed their home dir) then on entering correct details and clicking ok, the box refreshes with <domain><user name> (where braced values are replaced by literal values). If a user is connecting from outside via vpn (hosted though a different department's server) the domain is replaced by their computer name.If the password is re-entered, the same happens, in an infinite loop, and no access is ever given.When I say the staff share is intermittent, there likely is some pattern, but I haven't been able to work it out yet -- I think it may have something to do with how recently the account was set up, or physical location.

CentOS 5 Networking :: Samba Share Not Accessible From Windows Machine?

Feb 13, 2010

I have Linux installed on one machine with samba running and a second machine running XP. They are going through my router and I am using the same username/passwords for both machines and I have even gone to the point of allowing access to everyone for the share I created and the worgroup in samba is MSHOME just like my XP machine. When I view (or search) my workgroup computers my Linux machine shows up and so do the shares I created but when I try to open them I just get a message that permission is denied and I may not have permission to use this resource. I even tried setting access to the shared folder to 777 but still I can't open this share. Has anyone got any idea of why this is?

Networking :: Samba Setup - Windows 7 Host - CentOS Machine Using VirtualBox?

Jun 23, 2010

I am trying to set up samba in my CentOS virtual machine that is running on a Windows 7 host. I have found a tutorial in the How-Tos on this site but I'm not sure if they are exact and I'm paranoid about messing something up. The link to the tutorial is below. Is there anything that I should do different or anything that I should be aware of? Also, once this is set up, how do I transfer files between the two machines?

Ubuntu Networking :: Wifi Takes A Minute Before It Tries To Connect After Boot/suspend

Oct 16, 2010

Basically when I login back from a suspend or after I boot the pc, the wifi takes 30seconds to a minute before it starts to connect. This makes it very annoying to have to wait for no reason.

Basically the issue is caused by the wifi not having a script to search for a network after a suspend.

Ubuntu Networking :: Natty Netman Connect/disconnect Wifi Every Minute?

Jun 26, 2011

I was happily running Ubuntu 9 but since I cannot get security updates for it anymore I had to upgrade to 11. Now I'm on Natty, and the "NetworkManager" apparently cannot deal with my latop's wifi card which worked fine for years under ubuntu 9. The laptop is a Dell latitude D610 and the card is an intel ipw2200 minipci. I used to just run /etc/init.d/network restart after I logged in to get the wireless to come up, if it failed by itself, but now I get a message that that's deprecated. Nice.

I'm running WPA. If I don't create a wireless configuration in the network manager, wireless never connects. Ever. If I do create a configuration, the connection comes up for about a minute, and then drops. And then comes up. And then drops. And then comes up. And then drops. It's insane. Also, I get a series of "Auto <ssid>" entries in the NM settings area.I dug around in /var/log, but all of the wpa_supplicant logs are of size 0, except the gzipped backups, which are all size 20. Go gzip. The syslog has some messages in it about 4-way handshake failed, and association taking too long, but since the laptop has no network connection I don't have an easy way to post those here.I just want the wireless to come up, by itself, when I turn on the laptop like it used to. I don't want to have to deal with retyping the (long and complicated) WPA password every time I wake up the machine, nor deal with the "keychain." How do I get there?

Ubuntu Networking :: Network Connections Keep Dropping?

Jan 30, 2010

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

Ubuntu Networking :: Wireless Internet Dropping Out?

Feb 17, 2010

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).

Ubuntu Networking :: Wireless Dropping But Not Windows?

Feb 25, 2010

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

Ubuntu Networking :: Wireless Keeps Dropping At School

Oct 5, 2010

I'm running ubuntu 10.04 on my laptop with broadcom BCM4322 wireless card.Basically what keeps happening is my wireless will stop working, then network manager will notify me that I have lost signal. It will then try and reconnect, but it never seems to be successful. The only way I can get the wireless to work again is if I disable wireless then re-enable wireless (or do a complete system restart).

However, it does not seem to have this problem at home. The only difference I can think of from home and school is either encryption types (the university uses WEP, I use WPA) or the fact that at home there is only one access point and at university there are multiple access points all with the same SSID.Anyone have any idea how to make my laptop stop dropping connection all the time?
