Networking :: Unable To Remotely Connect To X?
May 25, 2010
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.

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 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?

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 am trying to setup a dhcp server for my internal network. I have two NICs, a modem, and a wireless router. I have my server connected directly to my modem which is providing me with Internet access on eth1 and is working fine. I have dhcp and dns setup on eth0 which is connected to my router. The router shows that it is connected to the Internet but when the router gives a client computer an IP address, the client is unable to connect to the Internet but can connect to the router. I will post my configuration files below with my current configuration.

I just switched from Ubuntu to Fedora 13 because I was unable to get Ubuntu to connect to wireless networks. I tried everything suggested in help and forums, and kept getting "Bad Password" with WICD and Network Manager. Now, with Fedora...I still can't connect.
Problem #1: The guide says to "...make sure that the relevant wireless interface (usually eth0 or eth1) is controlled by NetworkManager," and that I do this via: System>Administration>Network
However, there is no Network option under System>Administration.
Problem #2: I open Network Manager, which displays a list of networks. I click on mine, configure it with WPA and the right password, and it fails to connect: "The network connection has been disconnected."

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'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.

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

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?

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 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 was having no problems (that I knew of) browsing the web since installing Ubuntu 10.10 a week or so ago. I was previously trialling Win7 as my customers will likely be using that in the future. Then I wanted to go to internode.on.net. Got the following: Quote: Firefox can't establish a connection to the server at internode.on.net. or Quote: Oops! Google Chrome could not connect to internode.on.net
As it was just after Christmas I thought it must be down, for upgrades or maintenance etc. I later tried to go to Freebsd.org; same error. I've been having a small number of other websites give the same error. I thought nothing of this until I tried it on my wife's macpro. I could log onto all the websites I wanted to and none gave any indication of having been down. Both boxes are on the same adsl connection. I still can't access internode or freebsd on 10.10 yet have been able to access every website on OSX. Now, I was only looking at them for info but am worried I won't be able to access something important. (so far everything I 'need' is working)
ping just drops out. edit: weirdest thing! I just retried and now can not emulate the problem for internode. freebsd still won't show. that is less than five minutes between problems and resolution! I hadn't even posted! But I still would like to have an idea of what is going on. Here is the ping error for freebsd: Quote:

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?

I've been using transdroid on my nexus one to access transmission successfuly for some time now. But transmission is just too limited for what I really want. I really like either deluge or ktorrent and want to use them but this far I haven't been able to access either one remotely via transdroid. I'd greatly appreciate and advice anyone can offer.
I'm at work right now but can go into further details once I get home if need be. I've set up the webui plugin via the preferences menu in ktorrents settings and just can't get transdroid to connect.

This issue was prompted by Groupwise MTA not communicating with a Post Office that I had migrated to our first Linux box. I found out why, because I cannot communicate with it at all, other than through ethernet. I'm not sure what the problem is. I've checked the firewall and opened up all the ports that I'm trying to communicate on.ve made sure Apache is loaded
