Hey guys

I have a little permissive issue on my owncloud clint where i have mounted a NFS share.

Server setup.
Debian proxmox
ZFS Share

Code:

I need the right chmod and chown setting for this share, i added the no_root_squash so i thought i could chown the mounted folder, but i cant.
What am i doing wrong?

I use this for setting up my webapp
find /opt/lampp/htdocs -type d -exec chmod 755 {} \;
find /opt/lampp/htdocs -type f -exec chmod 644 {} \;

Have a nice weekend :)

[server] Home Server not accessible

Hello - this is my first post here and I apologize if it seems elementary, but this is something I have been working on for a week and still have not been able to get it to work. I've installed Ubuntu 14.04.3 on a Dell machine and hooked up the ethernet port directly to my Comcast router. My goal and purpose is to create and manage my own personal website. I've also downloaded and installed Plesk v. 12.0.18. My issue is that I can access my website directly on the server itself, but not from without and I'm not sure why. I suspect it is a DNS issue. My domain is registered with GoDaddy.com and I'm using freedns.afraid.org to point my domain to my server. But something still is not right. I suspect it is with the IP of the router and the internal IP of the server. I'm including several commands below and their results as a way to assist in troubleshooting. Any advice or guidance would be greatly appreciated!

HP Pavilion Internet Connection ALWAYS goes off.

Hello everyone, I hope I'm in the right sub-forum.

I have a really big problem. I have bought a HP Pavilion Laptop without an OS about a Month ago. I installed Ubuntu 14.04 on it and for some reason the Internet connection stopped working every few minutes. (The wifi icon was showing that it is connected but the pages would load really really slow and then say that the connection isn't working.)

I then installed all drivers (I think, via termina.) this stopped made it a little better. The connection now works to about an hour and then stops again. If I want the connection to work again I have to restart my Laptop.

Anyone knows what is going on and what I should do? It's really a big issue because I work on my Laptop and I need to have a good working internet connection to be able to work. I'm also new to Ubuntu so I don't know how to fix it myself. :(

Thank you so much everyone!

Hello Community my Blue-tooth is not working !

Rx and Tx bytes are counted but hcitool scan cant find any available device.
Wlan is working on the combo chip-set and the Blue-tooth icon is in the task-bar
I think wlan and blue-tooth use the same antenna because they use both 2.4GHz
No Blue-tooth errors in dmesg

Thanks in advance for any help !

Can I not use usb phone tethering without wireless card?

Hi. I am using another laptop which doesn't have wireless. I know it's dumb, but that is the way it is. I have successfully installed my usual phone tethering software and open it successfully. The phone says connection is established, but computer-side there is no internet. What could be the possible problems? I don't see why I would need a wireless card to have a usb connection.

Thank you

Been gone from here for a while, as not had any problems to speak of. NOW we have a problem. Was running 12.04 and my internet speed on wired was HORRIBLE compared to the 90mb with my Win 7 (separate computers with same MB/Memory .. FireFox browsers on both). So updated to 14.04 (took a while, but the install went with just a few minor hicups. AND the speed increased to 30 .. why not 90? What am I doing wrong? Anyone with a clue?

Installing wifi on Asus f205ta

Hello Everyone,
i am a newbie, but so far have successfully installed Ubuntu 15.04 next to Windows 8.1 on my Asus f205ta. Now im trying to get the wifi working following this guide: https://wiki.debian.org/InstallingDebianOn/Asus/X205TA
I have upgraded to Kernel 4.1.5, but whenever i try the last command ( cp /sys/firmware/efi/efivars/nvram-74b00bd9-805a-4d61-b51f-43268123d113 /lib/firmware/brcm/brcmfmac43340-sdio.txt ) Ubuntu can not find the nvram-file. In fact there is no file in the efivars-directory beginning with nvram (i have used "ls /sys/firmware/efi/efivars/" for this, i hope that is right).
Can anyone try to assist me please? By the way, could it have anything to do with a rather complicated installation of grub in 32bit efi mode for 64 bit ubuntu (installing windows in 64 bit is not possible since the drivers are only available for 32 bit)? also, my model is called f205ta instead of x205ta, but the specs are completely the same(i guess i got the european version or something like that). Wifi is working flawlessly in Windows. Any help would be much appreciated.
here some things that might be of interest to you:

[ubuntu] Wireless networking - I have to restart network-manager after booting and logging in

For some reason when I first boot I have to restart network-manager to get my wireless working on my machine. I upgraded from V 14 a week ago and this just started. I get the following in `dmesg` when I login:

Code:
IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready
When I do `sudo restart network-manager`, I see:

Code:
IPv6: ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready
Sometimes I have to restart it a couple of times for it to work.

Here is my system info, let me know what else is needed:

Code:

wifi driving me nuts, connection keeps dropping, need to reboot to reconnect

I have a Ubuntu 15.04
Toshiba Qosmio
Intel(R) Core(TM) i7-4700MQ CPU @ 2.40GHz
800.000 MHz
memory 32349mb
network controller:
intel dual band wireless AC 7260
ethernet contoller: qualcomm atheros AR8161 gigabit ethernet rev10

And every day and it can happen constantly during the day or night for no reason, the wifi connection just gets dropped, the computer does not try to reconnect, and I usually have to reboot to get the connection back again.
its not the router as I have just purchased another new one an ASUS RT-AC3200 and am using 2.4Ghz, and 2, 5Ghz bands, this has been happening for a few months now.

[SOLVED] Xubuntu 14.04.3 x 64: I removed network-manager and network-manager-gnome

August 16, 2015, 8:53 am

Hello. I just made a mistake, and now i want to repair it. I used this command sudo apt-get remove network-manager network-manager-gnome, and obviously now i have no internet connection. What are the options that i have to access the internet again?

I found a solution somewhere, but i don't know how to apply it. It was:
Step #1 = Boot an ubuntu livecd in "try without installing". (Make sure you are connected to the internet.)

Step #2 = In terminal type "sudo mount --bind /dev /chrootlocation/dev". (you will need to replace "chrootlocation" with the appropriate location of your ubuntu install, typically the label of the partition it's installed on. The partition must also be mounted so that you can access it.)

Step #3 = In terminal type "sudo mount --bind /proc /chrootlocation/proc".

Step #4 = In terminal type "sudo mount --bind /sys /chrootlocation/sys".

Step #5 = In terminal type "sudo cp /etc/resolv.conf /chrootlocation/etc/resolv.conf".

Step #6 = In terminal type "sudo chroot /chrootlocation".

Step #7 = In terminal type "sudo apt-get update". (If you don't you'll likely get an unable to connect error.)

Step #8 = In terminal type "sudo apt-get install network-manager".

Step #9 = In terminal type "exit". (This exits you from the chroot)

Step #10 = In terminal type "sudo reboot".

I am stuck at step 1, because i don't know what to write instead of chrootlocation.

I tried to reinstall it with this command: sudo apt-get install --reinstall network-manager, but unfortunately the file was not in my cache anymore

I am using a PC with wired connection only

Hello, I have setup my VM ubuntu server and real machine ubuntu server. However, they seems like blocking all the incoming connection, I can install the programs fine, which proofs it isn't network problem. I have attached screenshots from VM Server.

Incase your wondering, I haven't configured anything, it is just a fresh installed computer.

[ubuntu] Wired connection not working probably

When i plug in my ethernetcable, it says that it is connected and i have a VERY slow connection (takes like 5 min to open google, when it doesen't give up), then there was an update that fixed the problem, and i was able to use my ethernet for gaming. Then a new update was released and the problem occured again. I've tested the Ethernetcable on a windows laptop, and it works perfectly, also worked on my laptop before installing Ubuntu. The wireless internet in my house is very weak, and its almost impossible to play Counter Strike without the ethernet. I'm very new to Ubuntu and the terminal and all that, so if you need some information, please tell me what to input in the terminal :)

[ubuntu] Systemd dbus-org.freedesktop.nm-dispatcher.service continuously reloading

In looking at the syslog, I found the following. What I don't understand is why it continues to cycle through this every 1 minute or so. It seems to succeed when it runs, so I wonder why it gets inactive and active again.

Code:

I did a bunch of systemctl status until I found the service going from active to inactive:

Unfortunately,

Any idea on how to troubleshoot this?

But if I open the sub-folders of the share folder, it says: Access Denied (both CLI in the fileserver and Windows 7 gives same error)

even opening a file, i got same message.

Code:
root@dc:~# smbclient //alphaone.local/jdrive -Ualphagroup -c 'ls 2015/*'
Enter alphagroup's password:
Domain=[ALPHAONE] OS=[Unix] Server=[Samba 4.1.13-Ubuntu]
NT_STATUS_ACCESS_DENIED listing \2015\*


i am really puzzled of this issue because same config of samba i used, but doesn't work. is there something wrong with ubuntu 15.0.4?

or is there something to do the file system? i used ext4 though but still the same last file server i setup...

anybody can give a solution please?

please help.. thanks.

AMD-Vi IO_PAGE_FAULT errors, network goes offline until restart

So I recently upgraded the internals of my Ubuntu Server so that it's running a new motherboard, new processor, etc. And ever since then, I've been getting errors that look like this:
Code:
AMD-Vi: Event logged [IO_PAGE_FAULT device=02:00.0 domain 0x001d address=0x0000000000003000 flags=0x0050]
Sometimes they don't appear to do anything, however sometimes after encountering this, the network stops working properly.

I've searched for answers regarding this, however most are either unresolved or involve hardware that isn't relevant here (such as the graphics card causing the fault, and issues starting the desktop environment). Running
Code:
sudo lspci -vnn | grep 02:00.0 -A9
confirms this and lists info about the ethernet controller:
Code:
02:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10ec:8168] (rev. 0c)
        Subsystem: Micro-Star International Co., Ltd. [MSI] Device [1462:7969]
        Flags: bus master, fast devsel, latency 0, IRQ 87
        I/O ports at e000 [size=256]
        Memory at fe900000 (64-bit, non-prefetchable) [size=4K]
        Memory at d0800000 (64-bit, prefetchable) [size=16K]
        Capabilities: [40] Power Management version 3
        Capabilities: [50] MSI: Enable+ Count=1/1 Maskable- 64bit+
        Capabilities: [70] Express Endpoint, MSI 01
        Capabilities: [b0] MSI-X: Enable- Count=4 Masked-
I've also read that there is probably an issue with IOMMU, however I have no way to control whether or not this is turned on in the BIOS (there is no option), and adding
Code:
iommu=pf
or
Code:
iommu=soft
doesn't have any effect on the problem. Is there anyone that could shed some light on this? The server is currently unusable, since the problem happens usually within 5 minutes of booting, and only a reboot can fix it.

[ubuntu] Ubuntu Trusty Tahr - Wifi not working

Hello all
I hope you can help us!

My husband has a desktop computer (It's a Dell Vostro 400) with Trusty Tahr installed on it.
It was running fine until this afternoon when the wifi just stopped working. He uses a usb wifi stick (TP-Link 150Mbps) to connect to our wifi.

We have two sticks and have tried both.

But now when he plugs in the wifi stick it says that there are networks available but does now show or connect to any of them.
No settings have been changed. It's like the router is just ignoring him!

I can connect to the wifi fine with my netbook. Nothing has changed for me.

We have a cable that he can connect with, but it's pretty short and terribly inconvenient to have it inserted.

I hope that someone can help!

Thanks

[ubuntu] Samba share doesn't show all files

I'm on 14.04. I have a Netgear router that has a (readyshare) USB port where I keep a 2TiB drive as our home backup. It works well, I am able to mount it in Ubuntu and access it on Windows boxes with _almost_ no issue. On Ubuntu, it doesn't seem to list all the files in the folders. It lists an odd number, like 141 in one folder and 148 in another. And I can verify by accessing them on other machines or hooking it up directly to my machine, that it has much more than that.

Any thought on what samba issue could limit the number of files shown?
