Ubuntu Networking :: Lucid: Samba Causes Very Slow Shutdown (eventually By Timeout)?

Sep 11, 2010

Samba doesn't seem to disconnect on shutdown except by timing out, causing a loooong Lucid shutdown. (I can disconnect manually before shutdown by unmounting the Samba shares, and shutdown is then very fast.) Apparently Network Manager is somehow involved. I've installed a NM shutdown Samba script which works for the first user account, but not for the second user account (which was created and then put into the admin group).

Ubuntu Networking :: Lucid - Accessing Samba Shares Incredibly Slow From Win7

May 16, 2010

Since "upgrading" (ha!) to lucid I have had a number of problems that I am working my way through. The latest is accessing samba shares from a Win7 PC. It takes minutes to open the requested share from the Windows 7 PC. File transfers, once the directory is accessed, can be measured in bytes. It is an absolute trickle.

AFAIK the smb.conf is unchanged and, in any case, there is no problem accessing the shares from another linux PC.

Hardware :: Ata_piix Timeout On Flagstone SATA / Repeating Error Until Kernel Eventually "panics"?

Apr 9, 2010

When trying to install RHEL 5.4 on a Flagstone SATA (encrypted hard disk), linux timeouts while loading the ata_piix module.

ata2.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen
ata2.00: cmd 81/00:08:00:00:00/00:00:00:00:00/e0 tag 0 data 4096 in
res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout)
ata2: soft resetting port
ata2.00: configured for UDMA/33
ata2: EH complete

The above message is repeated several times until the kernel eventually "panics".If I use a non-encrypted SATA (Maxtor, Fujitsu, etc), the install works. It only fails with Flagstone SATA encrypted hard disks.

Ubuntu Networking :: Samba Not Working On Lucid 10.04

May 20, 2010

I had Samba shares (a public folder and a printer) running fine on Jaunty 9.10, when upgraded to 10.04 it stopped working.

I've tried several tips and following different threads to no avail.

when I run smbclient -L localhost or else smbclient -L I get:

session setup failed: NT_STATUS_NO_SUCH_DOMAIN
when I run smbclient -L TKA I get:
Connection to TKA failed (Error NT_STATUS_CONNECTION_REFUSED)
Here is my current smb.conf:


I installed samba4 but did't do any difference, so I uninstalled that. Reinstalled SAMBA and the config tool for samba several times. No difference.

Debian Configuration :: CIFS Mount Causes 90-sec Timeout Delay During Shutdown

Nov 17, 2015

I'm using Debian 8.2 from a very recent download of the latest NetInst (less than 2 weeks). I'm sort of new to Linux - More accurately, I've used Unix and Linux extensively in the past, so most of my knowledge is dated. In particular, the whole systemd / systemctl paradigm is completely new to me.

Problem: I've added an entry to /etc/fstab to mount a NAS drive as CIFS. When I do a system shutdown or reboot, the system hangs for 90 seconds trying to unmount the NAS. If I manually umount the NAS prior to shutdown / reboot everything works fine.

I've done a fair amount of investigation and web searches, but haven't found a fix yet. Apparently several people were encountering similar problems about a year back, and it seems pretty clear that the root cause what ordering of steps in the shutdown process, e.g., WLAN being turned off before unmounting filesystems. This seems to have been resolved for most users (no one is discussing it any more), but I'm now running into the same issue. Ugh.

I tried to add a shell script to /etc/rc0.d to umount the NAS first in the shutdown process. This had no effect. I assume this is because the new systemd / systemctl paradigm supplants the old /etc/rc model of runlevel control, though it is rather baffling (to me, at least) as to why /etc/rc* still exists if the system is no longer using it...?

Here's some things I'd like to try, but how to proceed:

1. In the new systemd / systemctl paradigm, how do I examine and change the ordering of steps in the shutdown process? I've seen a lot of documentation on systemd, but nothing tells me how to do what I used to be able to do with /etc/rc with a simple rename of a symlink. If I knew how to look at the order of shutdown and change that ordering, I'm fairly certain I could identify and resolve this issue.

2. Is there some other way to mount my CIFS NAS other than editing /etc/fstab? Is it possible that my manual edit to /etc/fstab is the cause of this issue? My research into systemd indicates that it IS supposed to be compatible with /etc/fstab. I have not yet found documentation describing how to mount a filesystem at boot WITHOUT editing /etc/fstab ...

Ubuntu Networking :: Very Slow Samba Share Browsing From Mac

Jun 27, 2011

I'm running Mac OS on a home network that includes a Win 7 machine and a Ubuntu box (Ubuntu 11.04 (GNU/Linux 2.6.38-8-generic i686)). Connecting to, and browsing the shared drives I have on the Ubuntu box (which acts as my server) is extremely slow from the Mac, it seems that the icons especially take ages to load. I've found a few suggestions on the net that I've implemented to no avail i.e.
Are there any other settings I should play with, or is there an alternative to samba that will work faster on a mixed network and be compatible with everything?

Ubuntu Networking :: 10.04 Lucid Lynx Network WiFi Slow Speed

May 18, 2010

A lot of people have the problem to find themselves with Lucid Lynx 10.04 and experience massive issues when connecting to wireless - me too. As a service, here some relevant links which promise relief:


I tried all of them, and none reliably worked. Every solution which required re-association wtih the AP helped for some time, but nothing helped for long. First, don't let yourself fool by the disable IPv6 trap - while it is "enabled" it is acutally not used by Lucid! I have a clean install of Kubuntu 10.04 on an AMD64 Laptop with Broadcom STA driver: 03:00.0 Network controller: Broadcom Corporation BCM4328 802.11a/b/g/n (rev 03) However I can reliably stabilize my connection for some time either by manually disabling WiFi with the hardware switch or disabling WiFi by software means and re-activating. This brings speed at par with Kubuntu 9.10 until some time. Can anybody confirm this behaviour?

Ubuntu Networking :: Lucid Wireless - Web Pages Consistently Slow To Load

Sep 21, 2010

Laptop: HP 6910p Wireless Card: BCM4312 NO issues with wireless in 8.10 (intrepid) - fwcutter driver. Performed clean install of 10.04 (lucid) onto a brand new hard drive (July 2010) - fwcutter driver. NO issues with wireless in 10.04 (lucid) until a few days ago, when. my laptop shutdown because the battery died and I safe-upgraded to 2.6.32-24-generic. Currently I have chronic wireless connectivity issues - slow to non-existent. Ping tests (ping -c6 google.com or ping -c6 sometimes reveal 0% loss, sometimes 100% loss, sometimes "unknown host" - within 5 minutes of each other. Regardless of ping results, web pages are consistently slow to load. Skype will also cut out from time to time as the wireless connection vacillates. I have a MacBook Pro which I am using as my (wireless and consistently well-connected) control - and from which I am currently forced to draft this note.

Networking :: Slow File Transfers Using Samba?

Feb 2, 2010

I am running Samba on a debian Lenny box on a wireless home network. I find that file transfers to the samba share are very slow. It takes over a minute to copy a 40MB file to the linux box, but only 20 seconds to copy the same file to a windows XP box on the same network.

Anyways, I could use a little direction on how to proceed with this, I'm really not sure where to start,

Ubuntu Networking :: File Server On 10.04 Machine - Slow Samba

May 22, 2010

I'm trying to set up a fileserver on my 10.04 machine, and access the files from Windows 7 via wifi. I can see everything alright, but the transfer speed to Windows never gets higher than 70KBps. Both computers can access the web at 800+KBps. I've also checked with an OS X machine on the same network, which was also extremely slow, so I'm fairly sure that the problem is on the server's side.

Fedora Networking :: F14 Samba Server With Slow Write Speed

Aug 4, 2011

I had a F14 samba server working flawlessly now for a quite time. Unexpectedly about a month ago the write speed slowed down around 64kbit/s and that's really slow. I haven't changed any configs, only updated the server. I've troubleshooted this from many angles:
-It is not a network issue because sftp writes are good.
-It is not a RAID1 issue because write speed from another directory (locally) are good.
So basically samba is the only thing left.

Here's example from smb.conf:
comment = My share
path = /mnt/RAID_share
writeable = yes
browseable = yes
writelist = +smbuser

Here's a snip from logs today:
[2011/08/04 09:04:27.509273, 1] smbd/server.c:267(remove_child_pid)
Scheduled cleanup of brl and lock database after unclean shutdown
[2011/08/04 09:04:47.526336, 1] smbd/server.c:240(cleanup_timeout_fn)
Cleaning up brl and lock database after unclean shutdown
[2011/08/04 09:17:57.634660, 1] smbd/server.c:267(remove_child_pid)

[2011/08/04 09:18:17.635196, 1] smbd/server.c:240(cleanup_timeout_fn)
Cleaning up brl and lock database after unclean shutdown .....

There's a restart that is not software related.

Ubuntu :: Lucid Server - Fail To Login With A Timeout Error When Logging In Via Ssh

Jun 28, 2011

I have multiple computers set up in my home (self education on networking) with one used as the main machine, and the others set up as a variety of server types. The main machine is running Lucid, as gui based os. The others are all running the server version. NO Domain controller is installed, no DNS server is installed.

ALL of the server machines boot to a login prompt, allow user name and password entry, and then will fail to login with a timeout error. After anywhere from 8-15 tries, the login will eventually succeed. Error also occurs when logging in via ssh.

Ubuntu Networking :: Internet Keeps Stalling Then Eventually Just Disconnects

Mar 13, 2010

I just installed Ubuntu this morning and don't have much time to detail my problem before my internet goes out again. I am currently running Ubuntu 9.10 (Karmic Koala?). I just got this laptop earlier this week with windows 7 and decided to put ubuntu on it via Wubi. Anyhoo, I login and then enter my wifi password and eveythings fine. I can surf the internet for a bit and everythings fine. but after a while, the wireless indicator on the keyboard begins to flicker on and off (between a connection and no connection) then starts to stall. The first thing I did was install google chrome (always the first thing to do) and I accidentally downloaded the wrong version A-OK. After I saw I downloaded the wrong version, I downloaded the correct, 32-bit version and installed it. During the download it said I had a 750kBs speed, but took much longer to download than had it been downloaded at a consistent 750kBs speed. I then tried to use update synaptic and it began to download reload all 44 packages and stalled around 38 or so. My internet then disconnected (wouldn't reconnect) and the download failed. I went back into windows uninstalled Ubuntu and then reinstalled it. After going through the first few steps again I began to update via update manager and surfed the web. After a few minutes of surfing the indicator began to flicker than just went off. I then connected to my neighbors internet, continued surfing and then the internet just crashed. I've found that when its just lightweight surfing, everythings okay, but during a download or any 2.0 surfing, then things start to get funky.

Ubuntu Networking :: Windows Not Getting Along - Wi-fi Router Eventually Disconnects

I have two computers and a wi-fi router. A notebook with Ubuntu 10.04 and a desktop with Windows 7. Whenever the notebook is on, the desktop starts having horrible Internet speed, and eventually disconnects. If I turn the notebook off (or disconnect from the network) it starts working fine again. Both computers connect to the router via wi-fi. I should also note that the connection runs flawlessly on Ubuntu.

Server :: Nameresolution Timeout After Longer Samba Runtime

Nov 3, 2010

We are running several server with SLES10SP3 and samba. After the service is running for a while we are getting timeouts for 15-20 seconds during a ping on the fqdn before he can resolv the name, same happens with traceroute and ssh. ping on a ip is successfull at once and nslookup is not showing any errors.

After a restart of the smb, nmb and winbind services the nameresolution is functioning normally again.

I honestly dont know where to start looking, this is a virtualized system and i checked the hypervisor (vsphere) logs but those turned out clean.

CentOS 5 Networking :: Samba "net Rpc Shutdown" Remote To Vista

Nov 4, 2009

This is most likely a Vista config thing, but basically I'm using "net rpc SHUTDOWN -f 192.168.xxx.xxx -U username%password" to remotely shutdown both XP and Vista machines.
The XP machines shutdown fine. They have the same local user account names and passwords as the Vista machines. The Vista machines repond with NT_STATUS_LOGON_FAILURE.

I've checked (way too many times) that my usernames and passwords are correct, Ive disabled the Windows Firewall in Vista, and I've been googling for two days and can't really remember all the other things I've tried.I'm sure it's probably some kind of security thing in Vista, but I barely ever use Vista and don't know where to go from here.

Ubuntu :: Lucid (10.04) Wont Shutdown Computer?

May 2, 2010

My ubuntu won't shut down, it stops at the ubuntu logo (with the dots under it). It seems like the OS completely and successfully shuts down, also the harddrive spins down too, except for the computer. I belive this might have happened after I updated my bios. (due to hybrid gpu trouble)I did search on the internet, and found that it might be some ACPI related issues, and that I have to edit the grub's menu.lst file and add acpi=force.However my menu.lst file is blank, there is nothing in there.

I have tried to shutdown via the terminal too, but the same happens there. Last time I checked it successfully reboots, and standby works correctly. For me to shutdown this laptop, I have to remove the battery and the power cord for it to shutdown, or hold the power button for 10 secs, which is really annoing
