CentOS 5 Hardware :: Accessing Live CD Remote GUI?
Apr 10, 2010
I have been using the Centos 5.4 live CD to do volume resizing etc for root volume which can't be readily dismounted. I have also been using it to clone systems. It is a really great tool - even offering the same GUI interface I have come to know and love...One added feature which would be great for me would be to package "nx server" and/or "webmin" with it so it can be used to maintain remote and "headless" servers.
That way - when heavy duty maintenance is required on a remote system - the sysadmin (me) could ask the site owner to boot with the live cd - and do the rest remotely. Also it would make maintenance of headless servers easier.I'm not sure whether the live cd is inherited more or less complete from the upstream provider - or whether it is completely re-packaged at centos. I'm also not sure how technically difficult it is to re-package a live cd with extra services.

I cannot access a remote server(Ubuntu) using ssh or even using sftp from my ftp client. I've been accessing this server regularly for many months with no problem until now. There is a web server running and that's OK, so no problems there. I asked the owner of the server if he could access using ssh from within his LAN, which he could! So openssl is working from within the LAN, but not ouside of the LAN. I access the remote server by using one of [URL] free domain names. I'm aware that this service requires renewal or activity at least once a month and as far as I know this is up to date and working OK.
Is this a router gateway problem? I suspect that port 22 has been blocked, but what could block this port? It's been working well for so many months. As far as I can tell the owner of the server/LAN has not been tampering with the router, so what could be blocking port22? I'm currently accessing the server using vnc4server.
Another really weird thing is that when I access the terminal on the remote server via vnc4server and I ssh back to the server using one of [URL] free domain names, it works! So as I understand ssh is accessing itself by going out of the LAN and back to itself. This would suggest that port22 on the gateway router is working. But when I try to ssh from a pc outside of the LAN, I just get timed out!
* openssl working from within the LAN but not outside of the LAN.
* sftp not working.
* domain name from dyndns.com working and up to date.
* Web server is working OK.

I had remote desk running on a machine and I went downstairs the other day, turned it on, and someone was controlling the machine. Of course that's partially my fault since there was -zero- rd password set. However, my question is how did this person figure out my IP and get past the router to the machine? I don't have any forwarding setup. My router admin password is (has always been) strong. I guess my question now is: Is there anyway to restrict rd access to the local network?

I run a system that users may log into either remotely or physically. Multiple users may be logged in simultaneously because of the remote access, but only one user can be physically logged in at a time.With the current setup, however, if the physical user inserts a flash drive (which the OS mounts automatically) then the remote users gain access to the removable media.

in attempt to dualboot w7 and opensuse i manage to screw windows boot loader. I was hoping that with opensuse live cd i'll successfully save my data but i was wrong. I can't browse any of partition with any of browsers inside liveCD including dolphin. When i try to access it says: There is no application installed that can open files of the type block device (inodelockdevice). Do you want to try to install one? Is there another option to access partitions because I can't install another browser on live cd.

I would like to experiment a "green" idea of virtual desktop where multiple users are served by a single powerful machine.
I have a server running 24/7. The monitor of this machine is turned off most of the time and the OS is on the login screen.
Other users, in the same local network, use less powerful machines, which could be a thin client or an old Pentium 3 machine. They access their accounts remotely and work with the GUI as if they were sitting in front of the server. Each user sees their own desktop (different themes, screen resolution, etc.). And of course it can happen that several users could log in at the same time.
The usage is modest: mostly web browsing and the usual default applications (office, wine, gimp, etc.). In particular no games or any demanding applications. The users want to use their desktop in graphical mode only.
Question: How do we call this way of using a server? Is it possible with Ubuntu? And how to implement it?

i find this is an issue which might be tiresome for everyone except for those experts. Esp. for the computers which are dual booting(both windows xp and centos installed in the same computer), that when we are in CentOS we need to switch onto windows immediately. and vice versa. i see this is possible only by shutting down the centos/windows and then restarting onto the other OS.
Can anyone tell me the the solution to work simultaneously both xp and centos without the need of shutting down and restarting There maybe or may not be the solution...but i find the pleasure to know if there is for example, remote desktop connection in windows xp, is there any solution, we can work on windows via centos or vice versa ( in the same machine),

I have a small network with my Centos 5.6 box and a Win XP PC on it.I can access the files on the PC from the Centos box by bringing up the RUN window (ALT-F2 in Gnome) and typing smb://192.168.1.X/C (where X is the address of the PC), and I get a window with the C: drive from my PC. I can then drag/drop files between the Centos box and the PC. Here are my questions:
1) I want to script the file transfer, so how do I do this from the command line?
2) On the PC, I have 2 drives C, and E. They appear to be set up the same, but the E drive looks empty when I do this using the interactive method above.
I found this tutorial http:[url]..... but I can't get my PC "visible" in the smbtree.Really, I just want to write a script that does a backup on the Centos box and copies it to the E (External) Drive on the PC. (I'm a novice when it comes to administration)

I tried to reinstall Centos, and the reinstall failed due to a flash disk being pulled out in the middle of the operation. I am left with an un-bootable system and I want to access my data, if possible.
Prior to the reinstall the disk info was:
== BEGIN cat /etc/fstab ==
/dev/VolGroup00/LogVol00 / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
tmpfs /dev/shm tmpfs defaults 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
[Code]...
So, The disks are still intact (I hope) but the LVM information is gone.is there anyway I can access /dev/sda2? When I try mounting it from the Rescue environment the command hangs, i.e. nothing happens.

I have a webservice which runs under Apache Tomcat. The service is started via a script in /etc/init.d. During the course of the Web service processing, the software must make use of the two NVIDIA GPUs on the computer to do some graphics processing. When this system is booted but not logged in, the web service is accessible but the software cannot access the software cannot access the X server to do it's processing. However, when I am logged in, the user can access the X servers and run correctly. I have tried various solutions but I always have to be logged in to run the software. I seem to have permissions problems but I'm unsure how to resolve them
Is there any way to grant permissions to root (the tomcat service is started as root) to allow it to run the software without logging in?
I am running CentOS 5.4 with Gnome display manager.

I have set up VNC on my Centos5 Server via the instructions here:
[URL]
I am able to log in via VNC through a browser (on my Window laptop), however when I try to access my USB hard drive on the Centos Server, it says:
Error org.freedesktop.DBus.Error.AccessDenied
Does anyone know of any step by step instructions so that I can be able to access my USB Hard drive?
I have found a few posts on the internet about this, however the fixes are either vague/hard to understand etc?

I have set up two identical websites and want them to access the same mysql database. I've entered the username/password/db name in the website database.inc file. However, one database works fine and displays correctly, the other just gives a blank page. I've tested apache and it can display a different site (one that does not access any db). So is there a configuration that i'm missing. Do i have identify the two different websites that access the db?

I'm currently in the last steps of migrating a CentOS mailserver to the x64 version.However, under the old 32 bit version, I was using XRDP to access the Centos box from my Windows boxes.However I can't seem to find the XRDP package in the standard repos so this is prompting me to look at possible alternatives (XRDP was incompatible with my windows 7 box anyway soI had to RDP to another server of ours running 2003 to RDP into the mailserver which was far from ideal).Basically, I'd like to be able to seamlessly access the Centos box with a standard RDP client.
I know VNC Server/Clients would be an option but RDP gives me the freedom of any windows box being able to access the server on the same adress/port without installing software on any windows box I encounter.Are there any viable alternatives to XRDP ?There's no "add-on" to VNC server that could enable it to accept RDP connections ?
