View 2 Replies View RelatedGeneral :: Handle Bad Block In Mass Storage Device?
Nov 2, 2009* I am implementing mass storage device on a test board.
* It contains NAND flash.
* Using corresponding "udc driver" and "g_file_storage" I could make my test board enumerate as mass storage device on my Linux machine.
* my 16 MB pen drive (test board) is now ready for read/write.
But there are some Bad Blocks on the NAND.Hence copy is not complete. Although on Linux machine there is no error message. Now , what is there in a normal pen drive which manages the Bad Block or what am I missing so that such Bad Blocks are managed.
Here is the error I get on my test board :
mtdblock: erase of region [0x2c0000, 0x4000] on "Bon 2" failed
end_request: I/O error, dev mtdblock2, sector 5664
Buffer I/O error on device mtdblock2, logical block 708

View 2 Replies View RelatedUbuntu Servers :: Samba Permissions On Share Level
Oct 13, 2010I'm trying to set up my samba server so that all the shares are visible to everybody but that some shares can only be accessed by certain users. I have a folder Video that everybody can access without a username or password. I now want to create a share that only I can access called webserver.
This is my samba.conf
Code:
[global]
dns proxy = No
netbios name = DATABOX
guest account = nobody
restrict anonymous = no
browseable = yes
server string = server
workgroup = WORKGROUP
public = yes
security = share
[Video]
Writeable = yes
Path = /media/data/Video
Public = yes
[webserver]
Writeable = yes
Public = no
User = malteser
Path = /media/data/Webserver
Windows does not let me enter a username or password. I'm pretty sure this used to work.

Mar 9, 2011We have been using Ubuntu Server at our department since several months now. It hosts a website, e-mail and nfs(only intra).
It was set-up as RAID 0 with two 1TB Hard drives but I want to change it to RAID 1 for fault tolerance. Is it possible to change existing RAID level? If yes can someone point me to the proper place?
I tried "mdadm" documentation and level set option is available but no explanation available that whether it is only while creating the array or it can change the level too.
Ubuntu Servers :: WebDAV - Mountable But Empty Below 2nd Subdir Level?
Jul 3, 2011I am using Safesync from Trendmicro to backup my data. Since some time I am experiencing heavy problems. Normally my Backup should look like this: But when I am mounting it with WebDAV, it is looking different:
Code:
cdrewing@christian-desktop:~$ sudo mount -t davfs http://dav.trendmicro.safesync.com /media/Safesync
[sudo] password for cdrewing:
Gib bitte den Benutzernamen f�r den Server http://dav.trendmicro.safesync.com an; wenn du keinen angeben willst, dr�cke Return.
[Code]...
Note: When I am mounting Safesync with Nautilus, everything is functional and ok. But I need my command line access because I want to use rsync. A workaround could be to access the resource via the nautilus mount. Where can I find this via the command line?

View 1 Replies View RelatedFedora Servers :: Convert A Running System To RAID Level 1?
Sep 30, 2009I was recently requested to try and convert a running system to RAID level 1. I did not succeed in this task. However, I am still interested in accomplishing this task in a test environment.What I did was create a RAID device with a device missing e.g.
mdadm --create /dev/md0 --level=1 --raid-devices=2 missing /dev/sdb2
Once the RAID was up and running I created the /etc/mdadm.conf file so that it would activate the RAID device on boot. Once the device was created I copied all the data from the running root filesystem to the /dev/md0 device. The only directory that I didn't copy was the /proc directory. When I rebooted the machine I had a kernel panic and the system couldn't find /dev/root. I would greatly appreciate it if someone could provide some information/tips regarding the problem.
OpenSUSE :: Move Transparently Between Run Level 3 And Run Level 5 As Autologin User?
Aug 10, 2010I've been able to kludge a kill script which finds the correct pid for the kdeserver (or gnome server) after my system comes up in run level 5 so I can drop back to run level 3 mode. Lots of experimentation showed me that using telinit 3 and telinit 5 would occasionally leave the video memory in a mess and I would have the black screen of death.
I set the security parameter setting to autologin for me since I am the only user of my machine, but I still have to kludge the default setting under sysconfig (the DEFAULT_WM) under Window Manager to pick a certain window manager, so it takes time to manually switch the desktop.
Right now I can leave the gui and drop back to cli, but painful experimenting showed me that killing the X server is a no no. Right now I kill the kde server, which sends the SIGTERM to the X windows manager, which then figures out that it has to shut down.
Questions: Is there a better way of doing this? Apparently openSUSE figures that we have multiple users logging into the gui desktop, so the gui is always kept running and a login window with the desktop manager option forces the user to login in. With autologin, this never happens, but no choice of desktop is possible on the fly.
Can some type of script be set up to painlessly enable this to happen? And what is the best way of bringing either the Gnome or KDE desktop manager down gracefully? I do get lots of error messages as the system attempts to recover and X shuts down. It appears that apparently the single user with autologin is left out in the cold.

View 1 Replies View RelatedUbuntu Servers :: How To Block Torrents By Using Squid Or Firewall
Jan 5, 2010I've been all around the net and can't find a "simple" answer how to block our LAN users from downloading torrents. Is it really that difficult?
Here's our setup:
1. The Server's Configs:
2. sudo gedit /etc/squid/squid.conf
3. sudo gedit /etc/rc.local (to start Firewall rules on bootup)
4. Server NOT a DHCP Server
5. No other iptables rules are configured, just the above ones.
Before in a 1 NIC setup, I blocked Workstations MAC addresses in the Router + Squid Proxy Server (Not Transparent), it worked, but some Online Java Apps didn't work and users can't send/receive email so I abandoned the method.
Now, I installed transparent Squid Proxy with 2 NIC cards, it works, but workstations can still download torrents! I know Squid doesn't block ports, right? So the answer must lie in Iptables Firewall? I basically use Squid just to deny access to Facebook, Friendster, or other "unproductive sites".
Quote:
How to block torrent downloading by using a Firewall? Or is there another "simple" way?
I've heard that it's better just to allow regular ports (80, 22, 465, etc...) then block all the rest, this way, you can prevent unnecessary ports.
I'm not an Iptables/Firewall expert so can you pls. explain it a bit more detailed if that's the case.
I'm also aware of just telling our users NOT to download torrents, but I just want to prohibit it entirely.
I know I will be the most "uncool" employee in our office.
Ubuntu Servers :: Firestarter Doesn't Allow Anyway To Block Incoming Connection By IP
Sep 19, 2010What is the absolute quickest or easiest way to block an incoming connection by their IP address? I'm running an apache2 LAMP server on Ubuntu 8.10. For example, let's say I'm watching my server error logs and I see someone using a script to check for phpmyadmin and other such folders. Right away I know this is a hack attempt. Firestarter does not allow ANY way to block an incoming connection by IP (to my disappointment) and adding the IP to an apache configuration file requires an apache restart (way too much trouble and time).

Fedora :: Can't Switch To TTY Or Run Level 3 From Run Level 5
May 12, 2009Hi Guys,
here is my scenario:
I am running F10 x86_64 with Nvidia Quadro FX 3400.
I installed the drivers and it worked just fine. No errors generated according to Nvidia log files.
However, while in run level 5 when I try to switch to run level 3 by typing "telinit 3" or "init 3" the X server goes down and I get a blank screen. Same thing happens when I try to switch to a different tty session by <ctrl>+<alt>+F2 (or any F key for that matter).
I also noticed that when I shut down my system I can't see any more the screen where services are shutting down and their status ([OK] or [failed]).
Would appreciate your help on solving this issue.
