General :: Remotely Accessing A Mounted SD Card?
Jul 1, 2011
The why behind this is a little long winded so let me get to the technical question. I have a 16 GB SD card in my netbook as additional storage to the 16 GB SSD drive. The SD card is formatted fat32 (by a utility from sdcard.org which is supposed to and does make the card read and write faster than if it was formatted by the OS). The card mounts when I login to the netbook. The entry from mtab shows
Quote:
/dev/sdb1 /media/SD16 vfat rw,nosuid,nodev,uhelper=udisks,uid=1000,gid=1000,shortname=mixed,dmask=0077,utf8=1,flush 0 0
If I look at the permissions on SD16 I find
Quote:
ken@taylor13:/media$ ls -l
drwx------ 3 ken ken 32768 1969-12-31 19:00 SD16
sudo chmod 777 SD16 does not change the permissions.
The problem is I need to connect to the machine with a different user (due to a security hole in gnome-commander). As the card is formatted fat I cannot assign group permissions to it and my second user cannot access it.
I had previously had the card formatted as ext3 and it was so slow as to be unusable. It needs to be formatted fat. I am stumped.

I am trying to set up a ssh server on my desktop computer. It runs Ubuntu 10.04 with Win 7 (dual boot). I want to ssh into my desktop from any other machine (from anywhere), and I'm not sure if setting up a ssh server is the right thing to do. Also, is it secure? what kind of encryption does it use

I have an application running on a centOS machine that needs to access a database on a CentOS server. I granted access to all users with a certain user name and password.i opened up port 3306 as well with the following command: /sbin/iptables -A INPUT -i eth0 -p tcp --destination-port 3306 -j ACCEPTbut whenever i try to connect from my machine i get an error:ERROR 2003 (HY000): Can't connect to MySQL server on '172.16.102.129' (113)I am using mysql version 5.0.77 on centOS 5.5.

I have two machines. Desktop and X61s. I have a drive on Desktop called Ianthe. This is in /media. This is remotely mounted on my X61s machine (a laptop), as /media/Ianthe. It automounts when I boot it up. BUT, the same drive looks different when viewed on the remote machine. An example is a certain directory, which when viewed on Desktop has 21 files in it, but when viewed on X61s has on 7 files in it.
If, on the X61s machine, I go to Network > Windows Network > LBBARNET > DESKTOP > Ianthe and navigate to the relevant folder, I can see all 21 items. But if I mount it, I can only see the 7. I have tried rebooting X61s, but it remains the same. The permissions on all the files in the folder on Desktop are identical, so I can't see any permission reason why this should happen. And, if I copy one of the files on the Desktop which doesn't appear on mounted view on X61s then the copied version appears immediately on both views.
fstab on Desktop
Code:
# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>

I have an HP laptop with a recently installed copy of Mint 8 KDE Community Edition. I created the initial admin user account ("joseph") when I installed.
I had an existing home directory under a different name from another installation, so I added a user with that name ("joe") and imported a copy of the original home directory. The user "joe" didn't have the same admin privileges as the initial "joseph" account, so I added "joe" to the sudoers file and the same groups as the initial admin user.
Everything works perfectly under this arrangement, for the most part. Now here's the problem:
I have a T-Mobile G1 phone that uses Android. I've rooted and ROM-modded the G1, and have the microSD card in the phone set up with two partitions. The vfat partition stores all the photos, music and other stuff the phone needs. The ROM mod allows me to store apps on the SD card, so that second partition uses ext3 for its file system.
When I'm logged in as the admin "joseph" account and I insert the SD card in the laptop's card slot (or plug the phone into the USB port), the SD card can be mounted, and I have full access to both card partitions. I can see all folders. I do this to backup the contents of the card to an external drive (especially the apps in the ext3 partition, since that's been trashed on me once before on the phone).
However, when I log in as "joe", I cannot view the contents of the ext3 partition at all. I can see the vfat drive fine, and the ext3 partition mounts, but with user/group "joseph/joseph." When I open Dolphin to view the mounted ext3 partition, I get the error "could not enter folder /media/disk-1" at the bottom of the view window in Dolphin.
Here are the relative entries returned when I run "mount" to view the mounted drives:
/dev/mmcblk0p1 on /media/disk type vfat (rw,nosuid,nodev,uhelper=hal,uid=1001,utf8,shortname=mixed,flush)
/dev/mmcblk0p2 on /media/disk-1 type ext3 (rw,nosuid,nodev,uhelper=hal)
Note that the uid listed on the vfat mount is 1001, which is the gid for the "joe" account.
I know there must be a configuration setting somewhere that will allow the ext3 partition to automount under the "joe" user account. I suppose that using the admin account to change the permissions would be the easy way to do this, but there must be something that would do it automagically. I've ripped through all the config files I can find, but can't seem to find anything that would help.
All I'm looking for here is enough access to be able to copy the directories on that mount to my external drive.

I've tried to search online but I can't find anything that works on our netbook. The netbook has a default Squeeze installation. After inserting the microSD card (via a "microSD card adapter" into the built-in slot), when I double-click on "Computer" on the Gnome desktop, it shows "Multiple Card Reader", but I can't access it. fdisk -l doesn't show any new devices, but dmesg does show the following:
[ 2532.101119] usb 1-5: reset high speed USB device using ehci_hcd and address 8
[ 2542.344135] usb 1-5: reset high speed USB device using ehci_hcd and address 8
[ 2558.588138] usb 1-5: reset high speed USB device using ehci_hcd and address 8
[ 2558.836073] usb 1-5: reset high speed USB device using ehci_hcd and address 8
[Code]....
I can't mount /dev/sdb or mount /dev/sdb1 (fdisk only shows "sda1-3"). The system simply reports that "special device sdb does not exist", although during one attempt I did get a message saying "block device sdb (or sdb1) something...".
It's imperative that I can access this microSD card. It will be put into my mobile phone so I can have the Star Trek: The Next Generation theme tune as the ringtone. I'm sure you all - as will all of humanity - realise the importance of this endeavour

since upgrade from SUSE11.1 I have been having problems with SD-Card Not Mounting. I have an internal card reader on the USB bus. From lsusb: Bus 001 Device 027: ID 0bda:0151 Realtek Semiconductor Corp. Mass Storage Device
I upgraded to SuSE 11.2 in the hope that this would fix it but it was the same. I have noticed that if I physically disconnect the card reader and reconnect it, then the card works perfectly once. If I then remove it without dismounting it the system seems to detect its removal but the light on the card reader stays on.
The Umount/eject button does not appear in the devices pop-up until I have used the pop-up to open the card in a program. If I then close the program and use the eject button to umount the card it all works fine.
I therefore assume that there is a problem with the automatic unmount or in detecting stale mounts when trying to remount the card. could it be that this is related to the post sd card on pci not recognised - openSUSE Forums.

The Motorola mounts in 10.04 but I can't tell the size of the available disc space so don't know if it's some internal memory or the 16 GB microSD card. It shows some files and a setup.exe so I suspect it's not the card and don't want to screw anything up.

Does anyone know or recommend some software or a script to remotely power on a PC from standby to on, or even better from completely off?
I guess the completely OFF to ON is much more complicated - would probably require an extra piece of hardware(?)

I'm not terribly new to Linux, but I am new to the forums, so hear me out! I am in the process of creating an electronic mapwall for our meteorology program, and have designed the computing system from scratch. I have two Linux Boxes, each with capabilities for 6 attached monitors...a total of 12 displays driven from two machines. My intention is to have one machine be the master...it has a touchpanel control. The inputs to the touchpanel will then trigger events for the both the master and the slave machine to display. Each of them has a specific IP address (DNS entry), and are not on a subnet.
Now...is there a way to remotely login to the slave machine and have it display on it's OWN monitors? The code is Java and which works on the master machine to animate directories of .gifs for each of the master's attached monitors. I will most likely have Java execute shell commands for the remote login (ssh), but I believe the answer lies somewhere in the X-configuration. Do I have the machines in an adverse configuration (creation of a subnet would be better)? Lots of questions...lots of desire...few answers!

I set all of my family members up with Linux Mint so that their computers would stop punching themselves in the face, but I'd like to be able to control those computers when my mom calls up and wants to know how to "put her favorites in the drop box." I've got Parallels with WinXP, and Ubunutu VMs, so my OS isn't really a concern (although I'd prefer to use OS X if there was a slick GUI app). What's the best or most practical approach to getting access to these computers from across the country?

I am using some software that uses CUDA to run some stuff on the GPU.
If I am using ssh to connect to the box, or vnc even, and I try to run the program I get an error that no CUDA device is enabled. I have to go over to the machine and physically log in, and type "startx" to get it to detect the device. It can also be another use on the box using an X session, but one has to be started soemwhere on the box to get CUDA working. Is there a way to "startx" over an SSH session so that this will work and I dont have to go over and log in?

I have a machine with several IP addresses with eth devices like eth0, eth0:1, eth0:2, eth0:3. Can I restart only eth0 without bringing down eth0:1? It would be really convenient to be able to log in via SSH on eth0:1 and restart eth0 without locking myself out or not being able to bring the network back up.
If I stop eth0, will that automatically stop all the others?

I'd like to have my Linux box (a QNAP TS-210 NAS) send the order to go to sleep (or hibernation) to my main Windows 7 computer.As the NAS is running Linux, I can't use psshutdown from SysInternals' PsTools. Is there any Linux equivalent? Or some "magic packet" that can order the Win7 computer to sleep.I know I could install a SSH daemon and trigger a shutdown command from the Linux box using ssh, but ideally I do not want to install anything on the Win7 computer. I can install Linux software on the NAS, no problem about this. PHP, python and perl are also available on it.

I use TextMate on Mac OS X to develop. The files I need to edit are on a Linux machine, and I have the Linux filesystem mounted on my Mac OS X. Opening the files and saving them in TextMate is not a problem.What I want to do (from my Mac OS X) is be able to...SSH <linux>cd <folder>mate <filename>I want that to open up the file in TextMate on my Mac OS X (thus, shifting focus from my Terminal.app to TextMate.app). How can I achieve this effect?

I'm using Window-XP and need to remotely connect to a CentOS-5.X server.
UPDATE: I'm looking to visually, securely and with as small a footprint as possible manage a remote Linux system via an GUI. It's not clear to me if Linux has a default method for streaming the desktop. Before installing something on the remote Linux system, is there a grep or find I should run to see if there's existing support on the computer? looked at Xming, but couldn't tell what it's doing; meaning if like WinSCP it's just creating an interface on my end and running CMDs remotely, or if it's streaming the desktop.

For routine tasks i have to execute commands on machines running both winxp and linux. I usually do it via telnet. But the process is very manual as i have to authenticate for each machine then specify the command.
Is there any way that i could automate this job using a script or so?

I just narrowly passed another exam on UNIX Academy. Their DVDs are incredible. While I made some mistakes here and there.I was really stumbled upon a question that was formulated something like "SNMP for managing Linux machines remotely".I can't remember the exact definition. I'm not sure what it was about.I was under impression that SNMP it is a carrier protocol for commands like "ping" and "traceroute". I was trying to read about it online but it is way too broad and technical, they're loosing me on very first page. I suspect there's some kind of product or technology that uses SNMP in some way to handle Linux, I'm not sure.
