Networking :: Connecting To My VNC Server ?
Jul 3, 2011
I am having problems connecting to my VNC server. The host machine is running fedora core 15.
In the past I have been able to connect to the machine, but for some I no longer can't.
I have done the following but still am unsure what problem is
1. Verfied the VNC server is running
2. Verified my user "trb" is in the vnc users list
3. I have checked that my port is open (at least i think). i launched a terminal and did "telnet 127.0.0.1 5902" and successfully connected.
My vncservers config file which is located in /etc/sysconfig/vncservers
Code:
Here is the log file from my latest connection attempt.

I connected two machines, I have their given of the addresses ip in a static way and not with DHCP. I gave to the machine server the address: 192.168.0.1, and in the machine client the address 192.168.0.2.

I have a home server that I have setup to connect to via SSH. All is working well with that. I would like to have the home server access the internet through a VPN. However, if I do this, I am no longer able to connect to the server via SSH, even though I know what its IP address is.

We have a mac book connected to our network. It can surf the web and even get into our network files. However, these network files are on linux, and finding the open files (not password protected) is fine. But we need the mac book to get into the protected files to edit our media. When we connect to the linux server, there is a pop-up asking for a login. We enter the correct credentials that work for everyone else to get into our protected files, but these credentials don't work... There is a message that pops up: "This operation cannot be completed because the original file '<file_name_here>' cannot be found." But it found the other open files...? what do we do to get this to work? The macbook is 'os x' and the linux server is 'fedora 10'

I have the following setup: An ADSL Router (192.168.4.1) which plugs into my server (that has 2 network cards) Server(eth0-connecting to the ADSL Router) = 192.168.4.2 Server(eth1-connecting to the windows XP PC) = 192.168.4.3 And the windows XP PC = 192.168.4.4 if I delete the entire routing table and add a default route route add default gw 192.168.4.1 dev eth0 I get an error (I can't remember the error, the PC's at work) however if I unplug the cable going from the PC to eth1, I can then successfully add the default route, and I can ping the router, however when I reconnect the cable to the PC and Server... I can still ping the router (from the server) but I cannot ping the PC
if I try and add another route such as: route add -net 192.168.4.0 netmask 255.255.255.0 gw 192.168.4.4 it wont let me add the rule I have a feeling i am doing something really stupid here with the addressing scheme,

I want to use centos as a developer server on my desktop before deploying my stuff to the internet.
I have a netgear DG834G router. It's IP address on my local network is 192.168.0.1 and connected to the adsl line. The router is set up to act as an dhcp server too. On the router I have reserved ip address for the nics per their mac addresses.
My server is on a dual boot desktop. The other boot is XP and works fine, picks up dhcp.
I don't know how to connect Centos to the router.
I have tried to play with the network manager but to no avail.
I can ping localhost, interface eth0 is there, but i can't ping to the router.
I have set the manager system/administration/network to get dhcp automatically.
I can't activate the eth0 although the hardware device says it is OK.
I've looked at firewall and iptalbes.

I've been experiencing some home web-server slowdown issues lately, and I wanted to see if it's a problem with the server itself. I'm not sure if this might be the problem, but upon checking netstat -tn, I see over 15 instances of the following:

where 192.168.2.9 is the server's local address, the local address port varies, and the foreign address is the server's web address. If anyone knows what might be causing this and/or how to fix i

I want to connect my linux laptop (Mandriva 2008.1 x86_64) to my windows small business server. My issue is that I am not sure what I can and can't do in terms of any windows config changes. Can linux (I assume using Samba) connect normally?

I'm trying to connect to a data server (basically a big hard drive) in my lab with my computer. On the Mac that's at the workbench next to me, you enter Go -> Connect to Server. From there, enter the IP address that I have (I can't find a server name--just the IP.). It asks you which subsystem you want, queries you for a user name & password, and then opens a window with all the files. Meanwhile, on my Ubuntu machine, I have a "Connect to Server" option under "Places" on my main menu. But when I choose that, I need to select what kind of server it is, from several options that don't seem right. (It's not FTP, it's not SSH, it's not a form of HTTP, and that leaves "Windows share?") I've tried several things, but usually get back 'Cannot display location "smb://<IP-ADDRESS>/" The specified location is not mounted'. I've tried many ways of mounting this drive, but it usually gives me permission denied errors (even though I *know* I have the right login and password--I've logged in using the aforementioned Mac).

I have setup an ubuntu gateway server by using four NIC cards.
eth0 :210.212.235.107 is connected to the internet
eth1 :192.168.1.222 is connected to the local network
eth2 :192.168.2.222 is connected to another network
Here 192.168.1.222 is the gateway for 192.168.1.0 network and 192.168.2.222 is the gateway for 192.168.2.0 network.These network configurations are working fine, but i want to block inter network communication ie from 192.168.1.0 network to 192.168.2.0 network,i want to block the communication for securing the local networks more.I know iptable rule is enough for this purpose .But i cant find the apt rule for this purpose.

My flatmates are all able to connect. However, I am able to connect from work both wirelessly and through an ethernet cable.

I just installed Ubuntu server edition on to an old Dell desktop. The only problem is that I can't get the Internet to work. I have tried the following and I guess it doesn't work:
Code:
sudo ifconfig eth0 192.168.1.52/24 up
sudo route add default gw 192.168.1.1
Each of those commands don't give me any error and it would seem like everything works fine, until I try to ping google or any website and I get an error that tells me that no host was found. I am using version 10.04 of Ubuntu server.

I'm attempting to get 10.04 to connect to an SBS 2003 pptp vpn server, but for the life of me have been unable to find or implement a working solution. System previously had 8.x and 9.x and had no difficulty connecting to same server, but on a fresh install of 10.04 cannot connect.
tail -f /var/log/syslog shows the following:
Code:
Sep 10 15:19:32 ubuntu NetworkManager: <info> Starting VPN service 'org.freedesktop.NetworkManager.pptp'...
Sep 10 15:19:32 ubuntu NetworkManager: <info> VPN service 'org.freedesktop.NetworkManager.pptp' started

I'd document here the way to get to eDesktop through linux (debian, ubuntu) at the University of West Florida (UWF), since they appear to only support Windows through their documentation on the University web site, and the link through Argus (the secure web site) doesn't work in Linux. This is sometimes needed to use the University resources (libraries and computer programs) from remote locations, and otherwise a google search is fruitless. I had to have a guy in the computer science department show me how to do it. This may apply for other Universities with similar setups. It was impossible for me to figure it out on my own, I had to go back to my old 9.04 partition to get the info...
1) Open Terminal Server Client (Applications>Internet>...)
2) Insert as follows:
Code:
Computer: eDesktop.uwf.edu
Protocol: RDP
User Name: YOUR USERNAME
[code]...
3) OPTIONAL BUT RECOMMENDED click Save As and save it as a quick connect so you don't have to refer to this again.
4) Flip through the other tabs and configure as desired, and click Connect!

But from command line, using pppd dialing,i am unable to connect to server.I get only the following messages in /var/log/messages always.
Log:

Is there any specific VPN client using which i can establish a connection with the following information in hand ?

i installed unix services for windows 3.5 on a windows xp pro box and it installed fine. I configured nfs on the debian box and exported the ip of the client computer and forwarded port 2049 correctly. I followed the instructions for setting up teh nfs client on windows. However whenever i go to tools->map network drive and type in the server-domain-name:/file-address it says it cannot connect?

I'm having a bizarre problem with FTP transfers from my CentOS 5.3 boxes, All of my CentOS boxes appear to be limited at ~10kb/s when connecting to any FTP server outside of our network. We have no network infrastructure which would cause this, however when I use a windows based machine it is able to connect fine.
I took my laptop running Vista, and rebooted it onto a CentOS 5.3 LiveCD, and same issue.
I have checked our iptables, cleared the rules, removed the kernel modules, checked CBQ/TC it looks like nothing is limiting this. Also, other protocols work fine. Both the windows and linux boxes used passive transfers for it.
Is there anything other than iptables/CBQ which would be on a out of the box install of CentOS I should check? Is there any kernel settings for NAT connections which may cause this?

I ran a yum update this morning on my Fedora 10 box (i386), which updated the 'nfs-utils' package from 1.1.4-4.fc10 to 1.1.4-6.fc10. Before the update I was able to connect to the fedora NFS exports just fine from my Macbook Pro running latest version of Leopard on a simple home network. After the update, when I try to connect to the NFS export it waits for a while at leopard's "Connecting to Server" dialog box, and after about a minute I get a message saying "Could not connect to the server because the name or password is not correct" (though my UID's are the same on both systems). My /etc/exports and /etc/sysconfig/nfs files were unchanged by the update. I tried restarting the nfs services as well as shutting down iptables and setting SELinux to permissive, etc. with no success.
I get the following in /var/log/messages (192.168.1.102 is the address of my macbook):
I was able to download the RPM for the older version of nfs-utils and then do a 'yum localinstall' to revert to the older version. This fixed my issues completely and my setup works as it did before. However I am curious to know why the latest version of nfs-utils breaks my setup, and whether it is a problem with my setup or if I should just wait for the next version to come out and see if the same thing happens.
Here is my /etc/exports file. If I understand this correctly it should allow connections from anyone with an IP address on my local network.

To configure webmail in linux5, I�ve followed below procedures:
-Squirrelmail-1.4.2.tar.gz and unzipped under the folder /var/www/html
-cd squirrelmail-1.4.2
-cd config
-within this directory, ./conf.pl
-From main menu, I did choose 2 for domain (i.e. arafapparels.com). This is my official domain
-Then save and exit
-For IMAP setting, I did choose D
-Selected uw and save, then exit
-Then from command line, I wrote chown �R apache.apache /var/www/html/data (I created folder data in the above path)
-I created a folder named as attach to keep attachment in /var/www/html i.e. /var/www/html/attach
-Then typed grep �R apache /var/www/html/attach
-Then typed chmod 730 /var/www/html/mail/attach (Here squirrelmail-1.4.2 directory has been moved to mail directory)
-Then from web browser/Internet explorer, I typed http://localhost/mail/
-Here Username & Password appears. Previously I have created username.
-But when put Username & Password, below error message displays
Error connecting to IMAP server: localhost
13: Permission denied
But I gave permission by chmod 777 /var/www/html/mail and by using 555 but no result.

I'm using Postgresql 8.4.2-2. I'm trying to remote into my server securely. I figure I could do so with ssh. Apparently I figured correctly, as per, [URL] and [URL] I setup the ssh tunnel. ssh -L 5432:serverip:5432 Then I setup pgadmin3 to connect as follows:
host: localhost
port: 5432
user: postgres
maintenance db: postgres
And I receive the following error:
An error has occurred: Quote: An error has occurred: Error connecting to the server: server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request.
I'm not sure what the problem is. I can connect with Code: psql from the cli after connecting to the terminal via ssh. So I know that I'm using the correct password.
