having a bit of trouble…

urpmi --force --allow-nodeps teamviewer_linux.rpm

leads to an error...

by **doktor5000** » Dec 12th, '12, 00:34

And which error would that be exactly? My crystal ball is a bit foggy there unfortunately ...
Apart from that, what you probably want is

Code: Select all: urpmi --allow-force --allow-nodeps teamviewer_linux.rpm

as --force only assumes yes on all questions, but you want to install it even if the dependencies are not satisfied.

You may also want to take a look at viewtopic.php?f=7&t=1386

by **freetibet** » Dec 12th, '12, 00:38

this is the error

[root@CCTV cctvadmin]# urpmi --allow-force --allow-nodeps teamviewer_linux.rpm
unable to access rpm file [teamviewer_linux.rpm]
error registering local packages

I am trying to get a reliable VNC session… in Mageia 2 I used teamviwer but would love to use anything...

by **Ken-Bergen** » Dec 12th, '12, 00:46

If you're in the folder where your rpm is then

Code: Select all: urpmi --allow-force --allow-nodeps ./teamviewer_linux.rpm

If not in the folder give urpmi the complete path to the rpm.

Is there a VNC sever solution that is easy to set up with mageia 3 with M2 it was almost impossible…
I am on the command line remotely...

by **claire** » Dec 12th, '12, 13:19

You might want to try tigervnc or x2go, both are available in Mageia 2 or Cauldron.

I tried Tiger VNC but it seems it did not work or I did not set up correctly using urpmi on the command line what would be the procedure to set either of these up ?

by **djennings** » Dec 12th, '12, 15:42

x2go is very easy to set up. If you install it from the command line you will see some text telling you what to do.
On the client install x2goclient on the server install x2goserver and x2goserver-sqlite

There is also a mozilla plugin x2goclient-mozilla-plugin to view a remote desktop on a browser although I have not tried that myself.

x2go will use a lot less bandwidth than vnc because it only transmits changes in the appearance of the desktop over the link.

The X2go database keeps track of running/suspended/finished X2go sessions, mounted devices, etc. If you use SQLite as DB backend, X2go will run on one single server. For multi-X2goServer support use the PostgreSQL setup variant of X2go server. All files should be present for this setup. If not, please report it as a bug. ALTERNATIVE: PostgreSQL setup -------------------------------- This variant is for a setup of x2goserver that uses a PostgreSQL database backend...

Thanks I downloaded that and installed on the server and locally…
however the end user is not logged in… and I am 100 miles away..
it will be a server

I started a session…
[root@CCTV cctvadmin]# x2gocleansessions&
[1] 6485
[root@CCTV cctvadmin]#

but cannot connect as I guess the user is logged in so this may not be any use… no one can log in at the end site so I don't know what to do...

by **djennings** » Dec 12th, '12, 16:10

You do not need anyone logged in at the other end, and it does not matter if anyone is already logged in.
You have started the server, that is all you have to do apart from start ssh service.

If you are using ssh public key authentication you must tell the x2go client where to find the ssh key.

Oh and very important. The firewall on the server must not block ssh on port 22. If you cannot open an ssh session to the client, then x2go will not work either.

by **freetibet** » Dec 12th, '12, 16:15

SSH server is on… that is what I am using to communicate with it now…
the above session prompt is on ssh…
it fails to connect however…
Odd

What error messages do you see if you start x2goclient in a terminal?

by **freetibet** » Dec 12th, '12, 16:29

I am using the GUI version for Mac OS with quartz
this from client error log...

but it could be password negotiation..
seems only root user can connect ?
but when you try it fails authentication…
can I connect as another user somehow ?

OK actually I have got a bit further now…

Unable to create SSL tunnel:

can I see the same desktop they see at their end ?
This is actually what I need..
The program looks great, just need to get it working...

by **djennings** » Dec 13th, '12, 00:19

I know you can ssh as root OK, but can you ssh as the user? Depending on how your ssh is configured you might need to provide a public key for the user.
Also if you are using public key authentication be aware x2go does not work with a dsa key, only rsa keys work.

can I see the same desktop they see at their end ?

Not as far as I know. I cannot see anything about that on the project web site.

by **freetibet** » Dec 13th, '12, 00:27

yes actually I can't ssh as root I think Iogged in as a user and did su …
I don't know anything about dsa or rya keys..
in the client I have set not to try connecting with a shared key…

If I can't see the same desktop can I set up the user to automatically log in as a certain user ?
I really need to see the desktop at the other end...

If you have not set up any keys, then do not worry about it. Public key authentication is a more secure way of running ssh. It means you do not need a password to log in, and therefore cannot be hacked by someone guessing your password. On the other hand it complicates things for remote viewers like x2go or vnc.

In your x2go client configuration you have to set the user you want to log in as. root user will not work. It has to be a real user.

by **freetibet** » Dec 13th, '12, 00:49

yep I have done this and set as an ordinary user… it does not work, so something mist be wrong…
I have restarted the server but I read that there is no init.d script so I need to manually start it

it authenticates and comes back with…

Actually, playing with it a bit just now. Seems to be working OK. This was the install from the teamviewer website. RPM... Version 7. We use TeamViewer on all our servers. Just recently migrated several of them over to Mageia from Mandy. There were several hickups along the way like this. But overall Mageia servers seem to be going good.

And I also think the libxdamage1 was my big hangup at the time. The naming from libXdamage made searching for the package weird. Most the other deps equivalents are easy to find.

What do you use your servers for ?

by **lfields** » Dec 14th, '12, 07:11

What do you use your servers for ?

I've got all kinds of applications.

Web servers (lamp). These range from a couple of full blown web servers to several internal web servers for web application serving and data reporting. There are lots of great web applications these days for invoicing/client data/time keeping/etc... that can all run on 1 server. Then the rest of the office computers can be dumb with a browser and people just login via web.

Basic file servers. These range from industrial sites, to churches, to insurance companies. File shares, windows machines (my documents) shares, etc....

A few running as internet gateways/firewall/network-dhcp servers. These are small to medium lans, with squid/dansguardian content filtering. Many of the same places we have file servers running. And dansguardian works great, did a youth center and fine tuned it pretty well to let them surf but keep them out of trouble.

Have 2 working as Application/database servers in a couple of auto shops running AutoHouse, connected to several work stations at each location. AutoHouse is an application for generating work orders, using/ordering parts, generating invoices, etc.... All based around Auto Repair shops. You have a primary server with sql and autohouse running on it. Then workstations just run autohouse client and connect to the same database server.

And also several industrial control applications for data mining and reporting (scada) from the plant floor. All custom built applications and scripting wrote in house. Controls network, its mostly dedicated i/o, produced and consumed type data. We run a SCADA over the top of it to collect data, generate reports, and interface with plant floor machinery.

And yes, Mandriva/Mageia servers are at the top of all this running the show... So far Migrated to Mageia.
2 Web Servers
1 File Server
1 DataMiner / Reporter
1 Industrial Scada

And the nice thing about Linux, is I can make it what I want. I've got my own custom spin stripped down running on 512mb memory sticks / 256mb ram in mini wireless computers that monitor plant machinery vibration and bearing temperatures, all the way up to full blown file/web/gateway servers. Ive been running Mandrake/Mandriva/Mageia since 2000 I think. Version 6.0, still have the boxed set on the shelf. And the fun never ends.....
