• Boot menu doesn't show up

  - by Zloboo

  I found some topics about dualbooting, but nothing was exactly what I need, so: I have Win7 and I installed Ubuntu 12.04 LTS from a flash drive. Everything went smoothly and I was given the "for installation to finish, need to reboot" screen. I removed the flash drive, the PC restarted. I was expecting to be greeted with the menu where I choose the OS I want to launch, but instead the Windows happily starts.

• When will fglrx work on latest Xorg server 1.9?

  - by user9032

  As many laptops with an ATI Radeon (5470HD) in it, mine is having issues too when installing the proprietary driver fglrx (screen hangs on startup). I read somewhere that these issues appear because the latest fglrx driver doesn't support the latest Xorg server 1.9 yet, which is installed on Ubuntu 10.10. So my question is whether any of you know when ati will support the latest xorg server? Thanks in advance!

• Live CD works OK. Is it OK to assume a new install will work?

  - by ign

  I've got a Toshiba a505 laptop and tried the live CD with great results. However, I haven't found any reports on this PC working 100% OK on Ubuntu 10.10 yet. I do have seen (and tried installing myself) some reports that 10.04 didn't work (without some dirty hacking). In regular circumstances, is it OK to assume that a new install will work if the live CD works? Are there any tools I can run to check compatibility? Thanks!

• Assigning shortcuts (accelerators) to Nautilus 3

  - by abruski

  I want to assign some shortcuts to menu actions in Nautilus 3.2.1 running under Ubuntu 11.10. I followed the steps shown here How do you create a "new document" keyboard shortcut? but it did not work for me. Switched to gnome classic so I can get the normal menu, hovered over the desired action pressed the desired keys but nothing happened (restarted nautilus, re-logged and nothing). Any suggestions or ideas on how to assign custom shortcuts to actions in Nautilus 3

• Can I move the unity launcher in 12.10? [closed]

  - by Linds

  Possible Duplicate: Can I move the Unity launcher? I've just recently downloaded ubuntu 12.10, and just like everyone else using the Unity Launcher I would like to move it to the bottom of the screen. I know there are patches for 11.10, and I think for 12.04, but I haven't been able to find anything to solve this problem on 12.10. Is there a way, or is everyone else with 12.10 waiting for a solution as well?

• Where is "open with..." in Nautilus?

  - by perebal

  In Ubuntu 11.04 I usually edit my *.fig files by clicking on the icons. The application (script) which opened the file was texfig. This script was chosen by "open with..." in nautilus. But now there is no possibilities to choose other applications than the predefined ones appropriate to the mimetype. How can I define a default application (or a self made script) in nautilus for the x-xfig mimetype?

• Can't install NPM after installing Node on EC2 Linux instance?

  - by frequent

  I'm trying my first attempt on getting a node server set up on an amazon ec2 linux instance. I think I made it quite far. First problem I ran into was when trying to make Node the connection timed out after a while, so I need three attempts until I got this: LINK(target) /home/ec2-user/node/out/Release/node: Finished touch /home/ec2-user/node/out/Release/obj.target/node_dtrace_header.stamp touch /home/ec2-user/node/out/Release/obj.target/node_dtrace_provider.stamp touch /home/ec2-user/node/out/Release/obj.target/node_dtrace_ustack.stamp touch /home/ec2-user/node/out/Release/obj.target/node_etw.stamp make[1]: Leaving directory `/home/ec2-user/node/out' ln -fs out/Release/node node Which tells me, "Node is done", although I'm not sure it is also working as it should. Following this,this and this tutorial, I'm now stuck at installing npm. I think I first cloned into the wrong folder, which always gave me error 127, but even if I'm doing this: cd ~ git clone git://github.com/isaacs/npm.git cd npm sudo -s PATH=/usr/local/bin:$PATH make install I'm still getting this: #after cloning# make[1]: Entering directory `/root/npm' node cli.js install bash: node: command not found make[1]: *** [node_modules/.bin/ronn] Error 127 make[1]: Leaving directory `/root/npm' make: *** [man/man3/start.3] Error 2 Question:: Since I'm pretty much a newby at everything I'm trying here, can someone please tell me what I'm doing wrong and how to get npm to install? Also, in case I cloned into the wrong folder, is there a way to remove the "false clone" or is this not written to disk until I call make install and I don't need to worry? Thanks for helping out!

• Iptables blocking mysql port 3306

  - by valmar

  I got a Tomcat server running a web application that must access a mysql server via Hibernate on the same machine. So, I added a rule for port 3306 to my iptables script but tomcat cannot connect to the mysql server for some reason. I need to reset all iptables rules - Then tomcat can connect to the mysql server again. All the other iptables rules work perfectly though. What's wrong? Here is my script: iptables -A INPUT -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT iptables -A INPUT -p tcp --dport 24 -j ACCEPT iptables -A INPUT -p tcp --dport 80 -j ACCEPT iptables -A OUTPUT -p tcp --dport 80 -j ACCEPT iptables -A INPUT -p tcp -s localhost --dport 8009 -m state --state ESTABLISHED -j ACCEPT iptables -A OUTPUT -p tcp -d localhost --dport 8009 -j ACCEPT iptables -A INPUT -p tcp -s localhost --dport 3306 -j ACCEPT iptables -A OUTPUT -p tcp -d localhost --dport 3306 -j ACCEPT iptables -A INPUT -p tcp --dport 443 -j ACCEPT iptables -A OUTPUT -p tcp --dport 443 -j ACCEPT iptables -A INPUT -p tcp --dport 25 -m state --state ESTABLISHED -j ACCEPT iptables -A OUTPUT -p tcp --dport 25 -j ACCEPT iptables -A INPUT -p tcp --dport 587 -m state --state ESTABLISHED -j ACCEPT iptables -A OUTPUT -p tcp --dport 587 -j ACCEPT iptables -A INPUT -p tcp --dport 465 -m state --state ESTABLISHED -j ACCEPT iptables -A OUTPUT -p tcp --dport 465 -j ACCEPT iptables -A INPUT -p tcp --dport 110 -m state --state ESTABLISHED -j ACCEPT iptables -A OUTPUT -p tcp --dport 110 -j ACCEPT iptables -A INPUT -p tcp --dport 995 -m state --state ESTABLISHED -j ACCEPT iptables -A OUTPUT -p tcp --dport 995 -j ACCEPT iptables -A INPUT -p tcp --dport 143 -m state --state ESTABLISHED -j ACCEPT iptables -A OUTPUT -p tcp --dport 143 -j ACCEPT iptables -A INPUT -p tcp --dport 993 -m state --state ESTABLISHED -j ACCEPT iptables -A OUTPUT -p tcp --dport 993 -j ACCEPT iptables -A INPUT -j DROP My /etc/hosts file: # nameserver config # IPv4 127.0.0.1 localhost 46.4.7.93 mydomain.com 46.4.7.93 Ubuntu-1004-lucid-64-minimal 46.4.7.93 horst # IPv6 ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters ff02::3 ip6-allhosts Having a look into the iptables logs, gives me this: Jun 22 16:52:43 Ubuntu-1004-lucid-64-minimal kernel: [ 435.111780] denied-input IN=lo OUT= MAC=00:00:00:00:00:00:00:00:00:00:00:00:08:00 SRC=127.0.0.1 DST=127.0.0.1 LEN=60 TOS=0x00 PREC=0x00 TTL=64 ID=52432 DF PROTO=TCP SPT=56108 DPT=8009 WINDOW=32792 RES=0x00 SYN URGP=0 Jun 22 16:52:46 Ubuntu-1004-lucid-64-minimal kernel: [ 438.110555] denied-input IN=lo OUT= MAC=00:00:00:00:00:00:00:00:00:00:00:00:08:00 SRC=127.0.0.1 DST=127.0.0.1 LEN=60 TOS=0x00 PREC=0x00 TTL=64 ID=52433 DF PROTO=TCP SPT=56108 DPT=8009 WINDOW=32792 RES=0x00 SYN URGP=0 Jun 22 16:52:46 Ubuntu-1004-lucid-64-minimal kernel: [ 438.231954] denied-input IN=lo OUT= MAC=00:00:00:00:00:00:00:00:00:00:00:00:08:00 SRC=127.0.0.1 DST=127.0.0.1 LEN=60 TOS=0x00 PREC=0x00 TTL=64 ID=48020 DF PROTO=TCP SPT=56109 DPT=8009 WINDOW=32792 RES=0x00 SYN URGP=0 Jun 22 16:52:49 Ubuntu-1004-lucid-64-minimal kernel: [ 441.229778] denied-input IN=lo OUT= MAC=00:00:00:00:00:00:00:00:00:00:00:00:08:00 SRC=127.0.0.1 DST=127.0.0.1 LEN=60 TOS=0x00 PREC=0x00 TTL=64 ID=48021 DF PROTO=TCP SPT=56109 DPT=8009 WINDOW=32792 RES=0x00 SYN URGP=0 Jun 22 16:53:57 Ubuntu-1004-lucid-64-minimal kernel: [ 508.731839] denied-input IN=eth0 OUT= MAC=6c:62:6d:85:bf:0e:00:26:88:75:dc:01:08:00 SRC=78.92.97.67 DST=46.4.7.93 LEN=64 TOS=0x00 PREC=0x00 TTL=122 ID=23053 DF PROTO=TCP SPT=1672 DPT=445 WINDOW=65535 RES=0x00 SYN URGP=0 Jun 22 16:53:59 Ubuntu-1004-lucid-64-minimal kernel: [ 511.625038] denied-input IN=eth0 OUT= MAC=6c:62:6d:85:bf:0e:00:26:88:75:dc:01:08:00 SRC=78.92.97.67 DST=46.4.7.93 LEN=64 TOS=0x00 PREC=0x00 TTL=122 ID=23547 DF PROTO=TCP SPT=1672 DPT=445 WINDOW=65535 RES=0x00 SYN URGP=0 Jun 22 16:54:22 Ubuntu-1004-lucid-64-minimal kernel: [ 533.981995] denied-input IN=eth0 OUT= MAC=6c:62:6d:85:bf:0e:00:26:88:75:dc:01:08:00 SRC=27.254.39.16 DST=46.4.7.93 LEN=48 TOS=0x00 PREC=0x00 TTL=117 ID=6549 PROTO=TCP SPT=6005 DPT=33796 WINDOW=64240 RES=0x00 ACK SYN URGP=0 Jun 22 16:54:44 Ubuntu-1004-lucid-64-minimal kernel: [ 556.297038] denied-input IN=eth0 OUT= MAC=6c:62:6d:85:bf:0e:00:26:88:75:dc:01:08:00 SRC=94.78.93.41 DST=46.4.7.93 LEN=40 TOS=0x00 PREC=0x00 TTL=52 ID=7712 PROTO=TCP SPT=57598 DPT=445 WINDOW=512 RES=0x00 SYN URGP=0

• How can I set up a touchscreen as the non-primary monitor in a dual monitor situation?

  - by bazzjedi

  I have been looking for information about using a second monitor, and thought of using a touchscreen. Will a touchscreen monitor work in a dual setup if it is not the main monitor? I haven't found any information on this; I've only found information about the touchscreen being the main monitor. That is, except at this SU question (snippet below): If you mean do the touch screen features still work on the other machine, the answer is yes. Past that, you can even see some of the touch screen features on a non touch screen monitor (just not the multi touch features!) For example, on the taskbar, click (without releasing) on any icon and then drag the mouse up, and you will see that it does the same as using your finger and dragging up. I have a HP 2510 for the main monitor. I'm thinking of adding a HP 2310ti (the touchscreen) as the secondary. My graphics card is a geforce gtx 295. I'm running Windows 7 Professional.

• CIFS Mounting Permissions

  - by malco

  I have an issue that I;m going round in circles with, I hope you can help. The Set up: Server 1 (CIFS Client) - CentOS 6.3 AD integrated uing Samba/Winbind & idmap_ad Server 2 (CIFS Server) - CentOS 6.3 AD integrated uing Samba/Winbind & idmap_ad All users (apart from root) are AD authenticated and this, including groups, etc works happily. What's working: I have created a share on Server 2: [share2] path = /srv/samba/share2 writeable = yes Permissions on the share: drwxrwx---. 2 root domain users 4096 Oct 12 09:21 share2 I can log into a Windows machine as user5 (member of domain users) and everything works as it should, for example: If I create a file it shows the correct permissions and attributes on both the MS and the Linux sides. Where I Fall Down: I mount the share on Server 1 using: # mount //server2/share2 /mnt/share2/ -o username=cifsmount,password=blah,domain=blah Or using fstab: //server2/share2 /mnt/share2 cifs credentials=/blah/.creds 0 0 This mounts fine, but.... If I log su, or log onto server 1 as a normal user (say user5) and try to create a file I get: #touch test touch test touch: cannot touch `test': Permission denied Then if I check the folder the file was created but as the cifsmount user: -rw-r--r--. 1 cifsmount domain users 0 Oct 12 09:21 test I can rename, delete, move or copy stuff around as user5, I just can't create anything, what am I doing wrong? I'm guessing it's something to do with the mount action as when I log onto server2 as user5 and access the folder locally it all works as it should. Can anyone point me in the right direction?

• Smart card driven membership and door entry system

  - by Rob G

  I'm looking at putting in a smart card driven system at my local sports club (which doesn't have oodles of money), and since they're willing to pay for hardware, and I'm willing to do the technical setup, I was wondering if anyone had any experience in setting something like this up. Writing any software needed is not the problem, I've pretty much got that covered with various open source projects out there and custom code I'll write, but it's more the hardware side I'm not too sure about and I'm looking for advice from people out there. I'm sure there are numerous complications, but on the surface it looks fairly simple. I'd basically like to enable members to swipe/touch a smart card at the door to gain entry to the club, walk up to a touch screen PC and swipe/touch a card reader there to "login" to the system I create, which will allow them to book club facilities etc. I may even want that same card to then activate things like lights or music when they enter the room they've booked. Pretty Eutopian I know, but still, we'd like to get as close as we can. As I said, the software shouldn't be a problem, and on the hardware side, so far I'm looking at: All in one touch screen PC running Windows 7 or Ubuntu USB card reader (not sure which one to buy) Smart Cards (again, never bought these before) Door/lighting hardware that could be triggered (not sure here either) If anyone has any advice on implementing something like this - especially the items I'm not sure about above, and of course anything I've missed out that's crucial, I'd be most grateful. Recommended hardware that you've used for something like this would be fantastic!

• On Ubuntu, how do you install a newer version of python and keep the older python version?

  - by Trevor Boyd Smith

  Background: I am using Ubuntu The newer python version is not in the apt-get repository (or synaptic) I plan on keeping the old version as the default python when you call "python" from the command line I plan on calling the new python using pythonX.X (X.X is the new version). Given the background, how do you install a newer version of python and keep the older python version? I have downloaded from python.org the "install from source" *.tgz package. The readme is pretty simple and says "execute three commands: ./configure; make; make test; sudo make install;" If I do the above commands, will the installation overwrite the old version of python I have (I definitely need the old version)?

• [OpenCV] cvFilter2D works very very slow in Ubuntu 9.10 amd64?

  - by Hong

  Hi, has someone tried the cvFilter2D under 64bit linux? Recently when I was trying to port some code to the amd64 version of Ubuntu 9.10, I just found that the cvFilter2D works really slow. The version is Opencv 2.0. The code is as follows: CvMat *mat_src = cvCreateMat(128, 128, CV_32FC1); CvMat *mat_dest = cvCreateMat(128, 128, CV_32FC1); CvMat* mat_kernel = cvCreateMat( 25, 25, CV_32FC1); // initialization ... cvFilter2D( (CvMat*)mat_src, (CvMat*)mat_dest, (CvMat*)mat_kernel, cvPoint( (25-1)/2, (25-1)/2)); // I needs approximately 100ms to finish that... My CPU is Intel 2.4G However, the Opencv 1.1pre only cost me 3ms for the same code...

• Why doesn't a 32bit .deb package install on 64bit Ubuntu?

  - by codebox_rob

  My .deb package, built on 32-bit Ubuntu and containing executables compiled with gcc, won't install on the 64-bit version of the OS (the error message says 'Wrong architecture i386'). This is confusing to me because I thought that in general 32-bit software worked on 64-bit hardware, but not vice-versa. Will it be possible for me to produce a .deb file that I can install on a 64-bit OS, using my 32-bit machine? Is it just a matter of using the appropriate compiler flags to produce the executables (and if so what are they), or is the .deb file itself somehow specific to one processor architecture?

• Build .deb package from source, without installing it

  - by Mechanical snail

  Suppose I have an installer program or source tarball for some program I want to install. (There is no Debian package available.) First I want to create a .deb package out of it, in order to be able to cleanly remove the installed program in the future (see Uninstalling application built from source, If I build a package from source how can I uninstall or remove completely?). Also, installing using a package prevents it from clobbering files from other packages, which cannot be guaranteed if you run the installer or sudo make install. Checkinstall From reading the answers there and elsewhere, I gather the usual solution is to use checkinstall to build the package. Unfortunately, it seems checkinstall does not prevent make install from clobbering system files from other packages. For example, according to Reverting problems caused by checkinstall with gcc build: I created a Debian package from the install using sudo checkinstall -D make install. [...] I removed it using Synaptic Package Manager. As it turns out, [removing] the package checkinstall created from make install tried to remove every single file the installation process touched, including shared gcc libraries like /lib64/libgcc_s.so. I then tried to tell checkinstall to build the package without installing it, in the hope of bypassing the issue. I created a dummy Makefile: install: echo "Bogus" > /bin/qwertyuiop and ran sudo checkinstall --install=no. The file /bin/qwertyuiop was created, even though the package was not installed. In my case, I do not trust the installer / make install to not overwrite system files, so this use of checkinstall is ruled out. How can I build the package, without installing it or letting it touch system files? Is it possible to run Checkinstall in a fakechrooted debootstrap environment to achieve this? Preferably the build should be done as a normal user rather than root, which would prevent the process from overwriting system files if it goes wrong.

• After upgrading to 12.04 the scanner from Brother Printer MFC-290C does not work

  - by Lorenzo

  I upgraded Ubuntu to 12.04 from 11.10. The printer works, but the scanner doesn't now. In 11.10 I had to install a special driver from Brother. The printer's model is Brother MFC-290C. The computer is a Toshiba Satellite. How can I get the scanner working? Update: I have a 64-bit installation on the Toshiba Satellite. Thank you for your instructions, Chad--24216.

• Commands don't have permission when using absolute path

  - by Markos

  I have folders set up this way: /srv/samba/video getfacl /srv/samba/video # file: srv/samba/video # owner: root # group: nogroup user::rwx group::--- group:sambaclients:rwx group:deluge:rwx mask::rwx other::--- default:user::rwx default:group::--- default:group:sambaclients:rwx default:group:deluge:rwx default:mask::rwx default:other::--- That means, user deluge has rwx to folder /srv/samba/video. However, when running command as user deluge, I am getting weird permission errors. When in folder /srv/samba/video: sudo -u deluge mkdir foo works flawlessly. But when using absolute path: sudo -u deluge mkdir /srv/samba/video/foo I am getting permission denied. When running sudo -u deluge id, I get output uid=113(deluge) gid=124(deluge) skupiny=124(deluge) which shows that user deluge is indeed in group deluge. Also, the behavior was the same when I gave the permissions also to user deluge not just group deluge. When executing as non-system user, it does work. The reason that I want to use absolute paths is that I am using automatically triggered post-download script which extracts some files into the folder. I have spent way too many hours to solve this problem myself. mkdir isn't the only command that fails, touch is doing the same thing, so I suspect that it's not mkdir's fault. If you need more info, I will try to put it in here, just ask. Thanx in advance. Edit: It seems that the root of the problem is acl set on perent folder /srv/samba, which indeed does not grant permissions to deluge (but neither denies it). getfacl /srv/samba # file: srv/samba # owner: root # group: nogroup user::rwx group::--- group:sambaclients:rwx mask::rwx other::--- default:user::rwx default:group::--- default:group:sambaclients:rwx default:mask::rwx default:other::--- If I grant the permission also to this folder, it suddenly starts to work so I believe that the acl on /srv/samba is somehow denying the permissions to deluge. So the question is: how do I set acl to both /srv/samba and /srv/samba/video so that sambaclients have access to whole /srv/samba and subdirectories and deluge has access only to /srv/samba/video and subdirectories?

• Blank screen after Switch User or Resume

  - by matt wilkie

  About half the time when I switch users or resume from standby or resume the screen goes blank (black). If I work the cursor keys I can hear the system bell when it gets to the end of the user list. I can also successfully login, going from memory, but screen stays black. Sometimes closing and re-opening the lid will light up the screen again. Pressing the special Function key to enable/disable external monitor connection has no effect [Fn]-[F5],[Fn]-[F6]. If none of the previous work I need to put the computer into hibernation or full power off to restore screen function. If I watch closely when switching users I think I can see the screen initially start to light up and then quickly fade to black. The computer is an Acer Aspire 3500, model ZL6, running Ubuntu 10.10 installed 2 days ago. No proprietary drivers are in use. I'll provide a list of hardware details as soon as I can figure out how to generate that (didn't there used to be an entry for hardware details under the System menu?). Possibly related questions: No resume after Hibernate or Standby When I resume from suspension - the screen is blank Switch user fails to complete successfully For what it's worth, blank after resume also used to happen occasionally when the laptop was running XP-Home, but nowhere near as often, perhaps 6 or 8 times a year. UPDATE: I found System Administration System Testing and ran the Monitor test. It went very very dark, but the window elements could be discerned, and the whole screen flashed (from very very dark to black). On the third repeat of that same test the screen went to full blaupck and stayed there. Moving the mouse, via touchpad, or touch keys did not wake it up again. I had to close the lid and put the computer into hibernate, and press the power button to restore it. UPDATE2: output of lshw: http://pastebin.com/q7n8676r, lspci: http://pastebin.com/6ujzVK4r UPDATE3: sometimes I can restore the screen by flipping to console 1 with ctrl-alt-F1 and then back to graphical with ctrl-alt-F7.

• can ping, but not SSH

  - by Matt

  So I have NetworkManager, connected to an AP on wlan1. I have wlan0 connected to a AdHoc network. I have Firestarter sharing my inet on the Adhoc. I have my ipod connected to wlan0, IP 10.42.43.101. wlan0 Link encap:Ethernet HWaddr ac:xx:12:81:7f:xx inet addr:10.42.43.1 Bcast:10.255.255.255 Mask:255.0.0.0 wlan1 Link encap:Ethernet HWaddr 00:xx:b3:98:f2:xx inet addr:10.0.1.61 Bcast:10.0.1.255 Mask:255.255.255.0 Now, I can ping my Jailbroken, SSH-enabled and running ipod touch: matt: ~ $ ping 10.42.43.101 PING 10.42.43.101 (10.42.43.101) 56(84) bytes of data. 64 bytes from 10.42.43.101: icmp_req=1 ttl=64 time=168 ms 64 bytes from 10.42.43.101: icmp_req=2 ttl=64 time=256 ms 64 bytes from 10.42.43.101: icmp_req=3 ttl=64 time=151 ms ^C --- 10.42.43.101 ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 1999ms rtt min/avg/max/mdev = 151.465/191.979/256.316/46.003 But I cannot SSH it: $ ssh [email protected] -vv OpenSSH_5.8p1 Debian-1ubuntu3, OpenSSL 0.9.8o 01 Jun 2010 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug2: ssh_connect: needpriv 0 debug1: Connecting to 10.42.43.101 [10.42.43.101] port 22.

• Am I misunderstanding chown and chmod?

  - by isomorphismes

  I want to either extend the size of my guest partition or figure out how to copy stuff from the guest partition to my normal /home directory. (Because of some other problems I can only run Xorg as guest, but I can log into virtual console as myself or root.) Here's the motivation: I want to torrent a large file. It's larger than my guest filesystem. But I have plenty of space on my real drive, I just can't log into it graphically. So I tried to set up a "pipe" to get the file out of the tmpfs. I did: su -u myself #catch mkdir ~/receiver_dir sudo su cd /tmp/guest-lkj567UIO/ #throw ln -s mario_pipe /home/myself/receiver_dir chown -R guest-lkj567UIO /home/myself/receiver_dir chown -R guest-lkj567UIO /tmp/guest-lkj567UIO/mario_pipe chmod -R a+rw /home/myself/receiver_dir chmod -R a+rw /tmp/guest-lkj567UIO/mario_pipe su -u guest-lkj567UIO cd /tmp/guest-lkj567UIO cd mario_pipe touch something #success! However, when I try to torrent to /tmp/guest-lkj567UIO/mario_pipe, Transmission says I don't have write permissions. But it looks like I just wrote there? And that everybody (a+rw) can write there in fact? Maybe this indicates I don't actually understand chown and chmod but nothing from their man pages pops out.

• Samba new file ownership, permissions configuration

  - by Martin Melka

  I have recently installed Samba on my server. Now I have a question about permissions and how to set it up. Currently I mount the Samba shared drive to my laptop with this line in /etc/fstab: //<host>/share /mnt/melka-server-data/ cifs username=<usrname> password=<passwd> _netdev 0 0 This works, as I can read from the files and create them (as root). The problem is when I want to create files as a regular user. I always get a Permission Denied error. These are ll outputs of the mounted folder: magicmaster@magicmaster-kubuntu:/mnt$ ll total 8 drwxr-xr-x 3 root root 4096 lis 11 14:15 ./ drwxr-xr-x 26 root root 4096 ríj 26 11:01 ../ drwxrwxrwx 8 magicmaster magicmaster 0 lis 12 22:12 melka-server-data/ and the inside: magicmaster@magicmaster-kubuntu:/mnt/melka-server-data$ ll total 4 drwxrwxrwx 8 magicmaster magicmaster 0 lis 12 22:12 ./ drwxr-xr-x 3 root root 4096 lis 11 14:15 ../ drwxrwxrwx 5 magicmaster magicmaster 0 lis 12 09:35 downloads/ drwxrwxrwx 2 magicmaster magicmaster 0 ríj 28 12:57 lost+found/ drwxrwxrwx 15 magicmaster magicmaster 0 lis 12 09:45 movies/ drwxrwxrwx 2 magicmaster magicmaster 0 lis 1 21:15 newest/ drwxrwxrwx 3 magicmaster magicmaster 0 lis 2 23:14 photos/ drwxrwxrwx 2 magicmaster magicmaster 0 ríj 30 12:44 software/ -rw-r--r-- 1 nobody nogroup 0 lis 12 22:12 zdar I called sudo chown -R magicmaster:magicmaster melka-server-data/ to try and change all the files to belong to me. Then the file zdar was created by magicmaster just by calling touch. I got the Permission Denied, but it was still created, though it belongs to nobody and I can't write into it. When I create a file as root, it still belongs to nobody, but at least I can write into it. What am I missing? I didn't notice anything in Samba config that would be related to this and I don't like the idea of having to log on as root in order to copy files.. Thanks

• Download lastfm tags into mp3 comment or genre tag

  - by Meng Tian

  for a long time I dream to have a songs lastfm tags in my music library, so I can use them to quickly generate playlists. There used to be a way to do that in amarok 1.4, but it never was stable. Than there is MusicBrainz Picard's lastfm/lastfmplus plugin. It is partially fine, but I cannot manage to make it look ONLY for the lastfm tags and put them into comments/genre/whatever but it always hast to tag everything. And it isn't particularly good with it, especially with small bands, songs without album etc. My music library is rather well organised. Most of the tags are correct. I also have quite some songs without an album. And I don't want it to find the albums for those songs, since it'd mess up my album view. So it must not touch the fields track name, track number, artist and album. All I want is that the most popular lastfm tags get into the genre or comments tag of the mp3, separated by semicolons, commas or whatever. I think I remember a script that did this job, but I cannot find. Does anybody know if there is anything like this? Would it be to hard to write this, for example as Banshee plugin? Thank you
