Ubuntu :: Connect To Remotely Prior To Logon
Aug 30, 2010
I'm running Ubuntu on a Zotac home theater PC. I wish to connect from another PC prior to login. The reason is that the home theater system has no convenient display. I've succeeded in getting a connection prior to logon from a PC using TightVNC. I've also tried Teamviewer running in Ubuntu without success. I'm now experimenting with X windows, but it seems complicated.
TightVNC is working well ecept that it opens a new session and I'd rather share the same session on Display 0. how best to connect to my Ubuntu home theater PC prior to logon and share the same session.

Is there anyway to prevent a user from being able to logon at a machine (Terminal and XWindows) but allow that user to logon remotely using SSH? This user is for remote capture of logs only - on a private network (no internet access).

Our system is based on RH4 and is using pam_tally and faillog to record failed attempts and to lock users out after 5 attempts. We have a requirement to provide a normal (non-root) user logging onto our system, with information regarding the number of failed logon attempts made on their account before the current successful logon (similar to the functionality provided by HP Protect Tools on Windows). My first idea was to add 'faillog -u $USER' to the bashrc, however by the time the bashrc is run - the user has been successfully authenticated and the faillog has been reset back to zero.

I have 5 PCs running windows XP and I want to remotely connect to a server that has Ubuntu.
I want all of them to have their own passwords and own desktops something like Remote desktop in windows and each one can run his programs separately.

I am new to Ubuntu and have been trying to make a remote connection to my home server. I think I almost there. Here's what I have done:
1) Installed Ubuntu Server 10.0 on a Pentium 2 with 256K
2) Installed SSH, MySQL, desktop GUI and enabled remote access
3) Port forwarded my Lynksys to 5900:22 and 80
4) installed Putty and TightVNC Viewer
5) Obtained a DynDDS account
My interanl IP Addy = 192.168.x.yyy
My External IP Addy = 76.xxx.y.zzz
When I run Putty, the connection times out (which I am guessing that my server may not be setup correctly). Since I am configuring all this at home, I am unable to simulate a true remote access unless I go to an outside location. Is there a way to test my connection from outside my network rather than waiting to login remotely from a place other than my home?

I have been using TightVNC (on XP) to remotely connect to my Ubuntu machine at home while in the office. This just worked. After upgrading to 10.10, I no longer can connect. Errormessage: Failed to connect to server (my ip) Looked at remote desktop settings, but these are not changed. Port forwarding is working and I use an internal fixed ip, so I can't imagine this being a problem (I doublechecked it anyway!). Anyone seen similar behavior> And, more interestingly, anyone know of a way to fix this?

Every couple of hours I am unable to ssh or vnc in to my system or anything else. I can remote into another PC on my LAN and everything works fine. The only things that fixes the problem is restarting the system. Could someone point me in the right dirrection to start trouble shooting this problem? I am still learning where all the log files are and I am generally new to linux

Just throwing in a quick question to see if anyone got any ideas about this.I'm unable to create a remote X session with TightVNC viewer. The local computer is a windows XP box and the remote server is running Slackware 13.
Using Putty on the XP box to connect to Xvnc through a ssh tunnel works just fine. However, when I fire up TightVNC viewer and try to connect to 127.0.0.1 as I'm used to, TightVNC viewer is unable to establish a connection to X. I'm puzzled.
This has worked when I used another XP box as local computer. I'm running all within my LAN. Can this be a firewall/iptables issue? I've obviously posted this in wrong forum category. Sorry about that. Starts this thread in server category too.

RedhatEL5(as guest) in Vmware ace, installed Samba, when:
#links http://localhost:901 ENTER
It works
but not with
#links http://127.0.0.1:901 ENTER
hence can't connect remotely from XP(host Computer).
Restarted accordingly, xinetd, with IPtables stop, #/etc/xinetd.d/swat file(disable = no) etc. How to fix this?

I just succesfully installed Centos 5.5 64bit with following package:
- httpd 2.2.3-43
- php-mysql 5.1.6-27
- mysql 5.0.77-4
and all these packages are running ok.
My question is how do i connect from Centos to another MSSQL server using PHP? I had read several article but cannot find the best way to achieve this because most of the instruction seems to be quite complicated. I found somewhere in this forum that all it need just this simple command: "yum --enablerepo=extras install php-mssql freetds". While others article said that i need to install "FreeTDS" and some ODBC driver. I'm a little bit curious since most of that article are using an older version of Centos and PHP.

I am having an issue with Ubuntu 10.10 and VNCServer. I can connect to my Ubuntu box remotely with VNC, but if I type any character anywhere, it closes out the window I was typing in. I dont seem to have a problem clicking and opening windows and applications, I just cant type anything into them without the window closing. Has anyone seen this behavior and know what the fix is?

I keep getting this error trying to connect to newly installed postgres server on Amazon EC2 running Ubuntu Maverick Meerkat....
Could not connect to server: Operation timed out Is the server running on host "....ap-southeast-1.compute.amazonaws.com" and accepting TCP/IP connections on port 5432?
I've updated config files, as follows...
pg_hba.conf
added
host all all 124.168.242.0/24 trust
where 124.168.242.0 is the IP range of my ISP
postgresql.conf
listen_addresses = '*'
port = 5432
I am attempting to connect with pgAdmin 3 client. I don't think the problem is the client.

I'm running vsftpd-2.2.2 on Slackware 13.1 and I'm behind a NAT with a dynamic IP. I'm using pasv_address, which makes it necessary to have a crontab that checks whether my IP has changed, and if it has, edits the conf and restarts vsfptd. It's hackish but it works. I have also enabled FTPES on the same port that normal FTP runs. I have allowed only the 5001:5003 ports and I am aware that the recommented is 50 ports. However I never had an issue with the transfers since I'm the only user and have at maximum two simultaneous transfers.
I can connect remotely with FTP and FTPES with every client I tried but I'm having issues locally. FileZilla refuses to connect on FTP and FTPES. WinSCP can connect on FTP but not FTPES. Issues are gone if I enable pasv_promiscuous, which the manpage strongly recommends not to use unless "you know what you're doing". I don't. Why is this happening? And, can I fix the local connections without resorting to pasv_promiscuous?
Here is my config and log files from a failed local attempt.
vsftpd.conf
Code:
anonymous_enable=NO
local_enable=YES
write_enable=YES
local_umask=022
[code]....

In this particular example I am using NoMachine's NX, although the behaviour also occurs when running VNC for instance. I'd like to connect from my laptop (1 physical screen), to my desktop at work (2 physical screen) via NX. It all works but the following problem occurs: When I connect with my laptop to my desktop I (almost) always am connected to the 2nd physical screen, whereas all windows appear on this first screen. I can interact with my desktop, use the task manager etc, see which windows are running, but any application I start, starts on the first screen (which I cannot see) and for the life of me I cannot move them from screen1 to screen2 without dragging them (which obviously is impossible since I only see screen2).The obvious workaround is: *before* you connect disable the second screen via the display manager but for me this is a non-pratical work around because it requires a lot of actions before heading home. how I can connect from a single-head desktop to a dual-head desktop without crippeling my desktop experience?

Tried turning firewall off, i tried port forwarding tcp port 22, but it still doesn't work. Also am unable to ping modem over WAN, i can ping the modem locally though. Tech support claims pinging and ssh is not part of the internet so they wont support it in any way.

I have a server at home running as a file server and DHCP connected to a switch with a wireless AP in there as-well. with this setup I can access the files and do some configurations via SSH on the actual server anytime I'm able to get the wireless signal, now lately I felt the need to be able to do the same but this time over the internet. I've read somewhere already that I'm gonna need a router with port forwarding and NAT, then know the IP address of the server but my problem is once you start talking about routers then you need broadband connection which is something I don't have. Getting a router is not much of a problem but without ADSL like connection I guess its useless, what do I need to do?

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'm having issues with my SSH server.The server is running on a Slackware 13.37 machine, using the default SSH server software, which I believe is OpenSSH.On my Windows machine, I've tried connecting to my Slackware machine but can only do so using the external IP, not the LAN IP, instead I get a "Connection Refused" error using PuTTy. I've forwarded port 22 for both UDP and TCP packets to my Slackware machine.I don't really know what information you need so just ask me and I'll respond to the best of my abilities.

I am thinking about upgrading, again, from Wheezy to Jessie. When I had Jessie installed, prior to a crash, I noticed that some of the Gnome games in Jessie are not as esthetically pleasing as they were in Wheezy. Also, some of the games (eg. mines) were slower and seemed to use a lot more CPU resources. So my questions are:
1. If I pin those programs that I want to keep will that also pin the dependencies for those programs?
2. If those dependencies are pinned, how might that impact other programs, in Jessie, that might depend on later packages?
3.If I don't pin those programs that I want to keep is it possible to install those programs from Wheezy after I upgrade to Jessie, without causing issues with Jessie?

I have a Canon MX320 printer/scanner/copier/fax to install on Sabayon 5.1. I have a choice of downloading a .deb file, a .rpm file, or a tar.gz source file from Canon Inc. Where do I have to put the file prior to install, will the files automatically end up in the correct place? (I haven't done this on Sabayon before, bet you couldn't tell!)
