Red Hat :: Unable To Remote VNC To The Server
Aug 25, 2010
I would like to ask the expertise here about this issue which I am having at the moment. I am unable to VNC to my server. I have configured all the necessary steps to enable the vncserver. But there will be an error stating "main: unable to connect to host: No route to host (113". I have checked on my network side which I did not block any what so ever port on the firewalls and the switches. I am able to ping the server but the main problem is that I am unable to remote VNC to that server. I have several servers which I have configured with the same configuration and only that particular 1 server that could not VNC. This is getting frustrating.

I am unable to run remote desktop from my fc 13 server, to my laptop. I have read the remote desktop setup and added port 6000 to firewall, added host name of server to xhost (nick@192.168.1.110). Added the line to /etc/gdm/custom.conf like in fedora guide (DisallowTCP=false). But i still get the error
[nick@pc1 ~]$ xclock
No protocol specified

I recently did a clean install of Fedora 11 (from Fedora 10). In Fedora 9 and 10 I used a remote font server so that I could launch HP OpenView over a VPN tunnel. The procedure would go something like this:
*connect to VPN
*xset +fp tcp/<hp_ux_server>:7000
*ssh -X user@hp_ux_server
*launch OpenView
OpenView requires the fonts that are installed on the HP-UX server, hence the need for the xset command. Now since the installation of Fedora 11, I cannot get the xset command to work.
xset fp+ tcp/<hp_ux_server>:7000
xset: bad font path element (#23), possible causes are:
Directory does not exist or has wrong permissions
Directory missing fonts.dir
Incorrect font server address or syntax
I have turned off the firewall to make sure it wasn't blocking the request. But to no avail. I have also had two other people with Fedora 11 machines try this, they get the same error. Were there major changes in the X server from Fedora 10 to 11+?

Trying to get OpenbavoPOS to connect to my remote Postgresql database, but so far i've only been able to connect to the local postgres installation. I _am_ able to access the remote databases with psql. I've read literally dozens of pages, and am pulling my hair out. I'm trying jdbc:derby.//192.168.15.10:5432/bravo I get back java.sql.SQLException no suitable driver found for jdbc:derby.//192.168.15.10:5432/bravo If I use jdbc:derby./root/bravo - all is OK, using a local database created in /root I have jdk installed on the client; does it need to be on the server also?
Server = CentOS 5.4 PostgreSQL version 8.1.21
Client = CentOS 4.8 PostgreSQL version 8.1.4

I have a low powered headless box (DLINK DNS323) running linux that I keep in a back room at home to handle large file downloads. It does not have X installed. Everything is handled at the command prompt through an SSH link. In the most common case, I log in from a remote location (perhaps a coffee shop), start the download, then disconnect and go about my business.
If I try to download from a free account of rapidshare, filesonic, or some another file service there is a manual handshake process (decode a captcha, wait for 60 seconds, etc) that requires a graphical client to complete.
I would like to somehow navigate through the handshake using my laptop (running Firefox) (perhaps through a proxy on the DNS323), but direct the download directly to the DNS323 (i.e., not routed through the laptop) so that I can disconnect and expect that the download will complete without further involvement from me or my laptop.
Is there anyway to direct a download to a remote path? Any other suggestions for solving the problem?

I have a marmitek x10 remote controller that I had been using in opensuse. However I decided to upgrade my distro to fedora 12. I setup everything that I need to for mythtv however Im unable to get the remote to work. IRW doesnt return anything yet I know the driver is working as irrecord picks up the input. here are the steps Ive followed...
1) I can see the usb device ok....
> lsusb
Bus 001 Device 004: ID 059b:027a Iomega Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
[Code].....
2) I know it uses the atilibusb drivers, which Im able to prove by doing the following:
> irrecord -H atilibusb ~/lircd.conf
When I press keys on the remote I see the input is received on the screen.
3) I manually start lircd....
> lircd -H atilibusb
4) when I try irw, I dont get any output what so ever.......
I did modify my /etc/sysconfig/lirc however I had been trying gnome-lirc-properties to see if that could get it working, so Im not sure if its applied a wrong setting in the config file.

It asks me for the ip address and the port.

I have a box (boell) running Fedora 10 sitting behind a firewall at school. I am able to freely ssh to and from this box to other computers (minion) within that lan. Outside of this network I cannot directly ssh to boell - I must ssh first to minion, then I can ssh to boell. I've spoken with the sysadmin and he's verified that the firewall permits ssh freely - i haven't had any issues like this with other boxes of mine there, so this isn't any surprise.
I have verified that the hosts.deny file is blank, iptables permits ports 22 (and 80) and I didn't see anything obvious in the sshd_config. I tried a tcp dump on the external host and boell while attempting to ssh from the former to boell. The packets appear to be acknowledged by boell, but this fails to lead to a connection. I've tried this process with external hosts in different locations with the same result. I have made few modifications to the default installation for F10, so perhaps there is some default somewhere I have to change. In any case, below I have attached excerpts of germane files.
======== ssh from boell =======

I installed Ubuntu 9.10 on a friends computer when Windows died on it, and though she has had relatively few problems with it, she still occasionally has problems that are really hard to impossible to fix over the phone. She is also not very knowledgeable with computers, so I was trying to guide her through setting up so I could connect to her remotely and try to figure things out, but I cannot get it to work.
I personally don't use Ubuntu on my computer, I use openSUSE and KDE so that does add to the problem, though I have used Ubuntu and Gnome a lot in the past.
I had her go to remote desktop settings and allow connections from other computers and allow other users to control the desktop, and at first I had her require confirmation and a password but it didn't work without it either. When I try to connect, it just hangs for a while then times out. I tried using KRDC and just VNC in the terminal with the same result.
There should be nothing on my side preventing a connection, but I am not positive. I am not very familiar with remote desktop outside of a LAN either. I am just trying to connect using her IP address, I don't know if there is anything else I need to include. Is there maybe some other setting that needs to be changed or maybe her DSL modem/router is blocking me though I don't know why it would, especially since P2P programs work fine.

I have Ubuntu 10.04 installed on an older desktop and when I first installed Ubuntu I set up Remote Desktop Vino services and was able to connect just fine with my Windows XP, Windows 7, Leopard, Snow Leopard PCs and my iPhone using VNC all just fine. So I apply updates to my Linux box and now it's broken. I can not remote into my Ubuntu machine at all now. So something with the updates is broken. I don't really use my Ubuntu machine at all, all it is used for is for a dedicated Folding@Home server. I attached a screenshot as what my Remote Desktop settings look like.

My desktop is running 'buntu 9.10 and I have recently aquired a couple of half decent servers running Windows server 2003. I have a few windows app's that I use regularly for work that I have had limited success in running with wine or in vm's. I stumbled upon a how to to call apps in a vm to run seamlessly on the host desktop and did some playing and have succeeded in calling app's on my servers from my 'buntu desktop, the command I have set in my launcher for one of them (DIALux)
My question is, can I change the default application/file association in 'buntu with a custom command so I can double click on a file and have it open in one of these remote app's??If I can, what is the correct custom command to be using as using the above doesn't work at all, it just tries to open the file with rdesktop not the remote app.

I've got an uber simple test mail script in php on my awesome new dev machine running Ubuntu:
PHP Code:
Unfortunately, something is preventing mail delivery. I can't tell from this error log whether it's the remote machine rejecting me or whether it's my machine rejecting the self-signed cert on the remote machine:
Code:
I'm wondering what I could change in my postfix configuration to remedy this problem.
I tried setting smtp_tls_security_level = may = may but this did not change anything.

The issue is that my CentOS workstation is in a vlan from where the Intranet's DNS servers are unreachable. For browsing the web there is an ISA proxy server, which I presume resolves DNS for my firefox. However, wget, host, ping and aria2c fail to get any sort of DNS resolution since they're being run from command line.I have exported HTTP_PROXY value, which provides me internet access on console, but,only when I connect using IP address. It fails on name resolution.
My question is:May I redirect the DNS queries to my home PC which would be running a DNS server on a non standard port?I was thinking of putting nameserver 127.0.0.1 in /etc/resolv.conf and then put iptables rule to redirect 127.0.0.1:53 UDP to a.public.ip.address:3535 UDP..I don't know if I am shooting blanks or what, I am not very much aware of this kind of setup.My main need is to provide DNS resolution to console apps.I want to utilize my company's idle bandwidth for bulk downloads, so, using proxy, SSH tunneling through my Home PC is out of question.

I am not seeing what i am doing wrong here, but here goes:
From my server I need to run a command for backup on 25 remote servers (through a script). Now I have pushed the public keys for remote ssh connectivity on all of them and it works ( I can push files using rsync without the need to enter passwords on the remote servers), howver, I need to run the following command:
ssh odsadmin@10.139.111.1 'cp -a /var/www/life /var/www/life-v4'
when I run this command, I keep getting asked to enter the password, I even tried putting sudo in front of the cp, but still get the request to enter the password.
