We are organizing an event for Open Source technology in college for 100 students and want to provide them access our corporate PC. Our aim is to provide them remote access to few 10-20 machines in our corporate to try out our product which runs on specific hardware.Anyone who can suggest me any secure colloborative tool which will let those students access concurrently.
View 2 RepliesThe 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 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 can not open the corporate intranet portal, runnnig on windows server 2008 with domain users. In Centos I could login just fine - firefox/konqueror just prompted me for my NTLM windows domain username and password - I typed those in and browers sucessfully loggem me in and I could surf the corporate portal. Note that NTLM authentication is configured as a fallback from kerberos authentication (so told me our portal admin)
However, in Fedora11 when I try to open the corporate (intra(not inter)net) portal, browsers just give me "Bad Request (Invalid Hostname)" error instead of prompting me for my domain username/password. I'm logged in on my F11 box as a local (not domain) user - as I did also previously on Centos Box.
I disabled SELinux, I disabled the firewall but still no luck. Not being able to open the corporate portal is a major showstopper for me, as I can not access many applications hosted there.
Migrating whole Corporate Windows stations to Ubuntu which is a huge thing so I'd like to do it right and as painless as possible to users.
Here's how it's done now: Main server are already running Linux for years with DHCP, DNS, IMAP, Postgres and SAMBA.
Windows machines are part of Samba PDC and when user logs in, Windows connects to the user profile on Samba server. When user logs out and logs to another computer, he/she has the same files and settings. Basically, nothing is held on local stations.
All printers on the network are printers with network cards, so they are not attached to any computer. The right printer is set with cmd script when user logs in, which makes it possible to make other printer as default if one is faulty.
I am currently reviewing what it means to switch over to Ubuntu and I have the following scenario. If I was to switch all the windows servers over to an Ubuntu solution. I already understand that file servers/ mail servers and resources can be provided Ubuntu 10.04. The issue comes with the user accounts access and control. In a windows environment, I have a domain with sub domain sites. I am able to control passwords in each site separately thought Active directory. I need the instructions on how to setup an LDAP server so that I can control access rights to different services located on different servers.
Example 1.
I have 5 mail servers and on the HR side, I have 2 email administrators. I wish to provide them access to only the relevant resources centrally. With out having to add users to different users repeatedly. For example, if I wanted to grant the two administrators access to all five servers. As I understand it, I would have to create the same user on every server and add a public key on every server, as well as set the administration rights for that user on each server individually.
I want to be capable of doing this like I am in a windows environment from some sort of domain controller equivalent. Things that I must be able to do, manage users public keys on each server centrally. Add and remove user's access to each server centrally. Finite control on what each user can do on each server. (i.e., add them to the sudo group or any other group for specific servers/server class I specify). To a lesser extent of requirement, I also need to be able to inform users they have to change there password every 3 months from when they change it. As well as enforce password rules, such as characters complication.
The project is to setup a corporate server that will bond 5 pci lan cards into one! The scope is to connect 5 ADSL routers and compine the speeds of all of them.
So i would have 5 routers each 2mbit ADSL would result on a 10mbit connection.
The problem is not only that.
Because this is a corporate network the server MUST also act as a router. This is necessary because people are remotely connecting from e.g. their homes to the network.
if this can be done with a Linux server or it is not feasilbe at all?
I am looking for solution that would allow multiple users distributed over several offices in several countries to access one corporate file depository. The features I am looking for, are as follows:
- There should be the way to establish user groups and then define for each folder access level (read/write) for every user/group. Every users is given his login and password.
- This file depository should be accessed from both Linux and Windows clients
- There should be a way how to sync certain folders/files on one's PC so that it is possible to work off-line and then sync back to the common depository.
Then I plan to launch some regular backup routine on that folder where all the files of depository are kept. I can imagine that the solution could be involving several tools, ie access for Windows users might involve setting up samba server, but I don't know how to establish all the limited access stuff for Win clients via samba.
In my company, they provide linux machines which has a 4 yr old Gentoo linux. Also the OS is loaded through Yukon PXE/netboot environment, and the users directory is mounted from an network location. Also they dont provide root access in these machines.
I would love to use the latest Ubuntu in this machine. Please let me know if it is possible to configure a ubuntu/xubuntu in this machine. I need to be able to login with my corporate user_id/passwd, because many of the tools use this for authentication. so just doing a ubuntu installation in this machine and mounting the n/w location would not help.
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'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.

View 4 Replies View RelatedI'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?

View 2 Replies View RelatedI 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.
