Fedora Networking :: Login To Remote Machine Through VNC Client
Apr 14, 2009
I am using VNC to login to remote machine (vncserver). My question is; How can I login to remote machine (vncserver) through VNC client, without having to login to vncserver first physical. For better explanation here is an example: If john wnat to login to vncserver remotely first he has to login the vncserver physically then he can login remotely.
Running Ubuntu 10.04 to 10.04 over LAN; I can SSH -X into my server just fine, and am able to launch various applications (Nautilus, Gnome-Terminal, Disk Utility, etc) but I'd really like a Gnome desktop. When I've tried the various StartX commands and gnome-session, but something just isn't clicking. Is there a way to have a 'second' Gnome session running on the client over the first?
To pre-empt some obvious solutions; I don't wish to use VNC, the lag drives me nuts, and I'd like to keep my gnome session running on the client machine if possible. If it's not possible, that's fine; it just seems like there'd be a way to do it?
Is there a good terminal services client available I can connect to my Windows boxes from Fedora12? I am willing to pay for a commercial license if there is a good one
I have recently installed fedora 14 and configured vpn to access my work network. I need to access some windows machines which although I can ping I cannot remote desktop into. When I go to Applications>Internet> Remote Desktop Viewer and put in the machine name (either just the machine name or the FQDN including the domain name) I get an error "Connection to <machinename> was closed".
i have a udp server running at port 60178. when i connect to it from localhost there is no problem. when i use the client from a remote host i am not able to connect. I changed my server firewall settings[Fedora 11] and added "udp 60178" to trusted ports but still nothing happened. I ran wireshark and observed that packets are coming to the server machine but server returns a "Port Unreachable" ICMP message and doesnt give the packet to the application.
No sure exactly what the problem is here? I am trying to get a X app running from a remote site on my desktop. I am using this proceedure:xhost +remote host xauth on local host the get 'Cookie'.
scp Cookie to remote host xauth merge Cookie into .Xauthority ssh to remote. export DISPLAY=local host:0 xfig xfig fails with "Error: Can't open display: local:0"
If I start another X using '-ac' ( not authinaction) and put to local:1 , all is well.
I have a mate who runs the IT in his office. He has recently set up and secured the network but now has an issue logging in to the network from home. Here is the message I got from him regarding the set up and what he is having specific issues with.
I was really pleased with the results on my Pen Test; the office itself is a pure MS environment but the testers all use Ubuntu 9.10 to hack with. The main tools of choice are Nessus and Ophcrack with a bit of NMap. It's pretty scary what you can do with just these tools. I had a Wireshark trace running all the time and it's fascinating to watch how these guys crack open a system. The only really major change I've had to implement on my network is to force the use of SSL as a transport layer for our remote desktop sessions. This has forced me to start using MS RDP Client 5.2 because it can use certificates on the session. The problem I've got now is that the Terminal Client in Ubuntu can't do this so I can't remote in from home on my Ubuntu laptop.
I have a number of Ubuntu machines running. Our NAS is FreeNAS. I am typing this on an Ubuntu 10.04 desktop that is successfully connects to an NFS share on the FreeNAS box every day. In addition, we have 3 10.04 server machines that also stay connected to the share successfully, Yesterday, I installed a new 10.04 server machine using IP 192.168.0.11. Everything works except connecting to the NFS share. It always returns with: mount.nfs: mount to NFS server '192.168.0.13:/mnt/amrd0s2/public-NFS' failed: timed out, giving up
Here's what I have checked: I can ping 192.168.0.13 (obviously) The NFS export mask is set to 192.168.0.0/16. The other machines are all on the same subnet as this problem machine (192.168.0.*) nfs-common, nfs-client, and portmap are all installed and running correctly. portmap is running correctly showmount -e 192.168.0.13 give the proper response:
Export list for 192.168.0.13: /mnt/amrd0s2/public-NFS/ 192.168.0.0 iptables isn't even installed (these machines are segregated in a private network behind a hardware fire all) There is nothing related to NFS is any of the syslogs. dmesg has one entry: [6.025966] FS-Cache: Netfs 'nfs' registered for caching which is insignificant. how to at least debug the nfs-client short of downloading the source and actually stepping through the code.
I've just set up NIS on my home network (probably not necessary on this scale, but I wanted to try it out). The server and the clients are all running Debian Lenny. I've got it up and running and have my NIS users on the server logging into graphical desktops on a client machine.My problem is this: The users cannot access a lot of services that are native to the client because they're not members of the right groups (for example, they have no sound because they're not members of the audio group). I figured it would be easy; just add users to groups with the usermod command but the response I get is that the user in question is not present in /etc/passwd. If I understand NIS correctly I'm not supposed to add my users to /etc/passwd on the client machines.
I can ssh from my local machine (Ubuntu 10.4 64bit) to a remote Linux server. When I try to copy a file back to my machine (or just ssh to my machine) I get the following error - "port 22: No route to host".ifconfig on my local machine gives one ip address for "lo Link encap:Local Loopback" and one for "wlan0 Link encap:Ethernet"; I tried ssh both.I work on a laptop with a wireless router (which is also the modem)
when i ping a remote machine to 172.16.1.55 then i get this result...how can get normal packets......
64 bytes from 172.16.1.55: icmp_seq=1 ttl=128 time=0.468 ms (DUP!) 64 bytes from 172.16.1.55: icmp_seq=2 ttl=128 time=0.448 ms 64 bytes from 172.16.1.55: icmp_seq=2 ttl=128 time=0.469 ms (DUP!)
I'd like to access a samba/SSH server which itself is connected to a VPN Server, therefore acting as a VPN Client. As soon as the VPN Connection is established, samba and ssh connections to this VPN Client get a timeout. But not all of them.
To get a better understanding I made an overview. The first one is a general network overview, without any VPN Connection, the second one with the VPN Connection established.
Network Overview without VPN I can access the server in several ways: *From the router via ssh (router runs ipcop with busybox) *From the laptop via ssh (putty via Windows 7) *From the laptop via samba *From the internet via ssh (port forwarding to the ssh server)
Everything is working as it should.
Now the server that runs ssh and samba service connects to a VPN Server on the Internet, this is also working fine. Now it gets weird. The only samba/SSH connection that is still working is ssh directly from the router to the server. Everything else gets a timeout: *From the laptop via ssh (putty via Windows 7) *From the laptop via samba *From the internet via ssh (port forwarding to the ssh server) Network Overview with VPN active
Why is that? It seems from the little understanding I have of vpn and networking, that incoming packages (like samba request from the laptop) don't get send directly back over eth0 but over the vpn connection. This seems somewhat logic, BUT ssh from the router is still working. Why from the router and not from the laptop? I really can't get my head around it.
Configuration Overview
tldr; One Client acts as VPN Client and samba/SSH Server. As soon as the VPN Connection is established samba/SSH stop working, but only partially.
I have set samba domain. I am able to add win 7 and xp clients. All r working fine. But I have a doubt. If I shutdown the samba pdc server, I should be able to login the client machine with the same profile (which I had, when the samba pdc server was up). Now , if I shutdown the sambapdc, I am able to login the client machine, but new profile is being created. How to avoid this.
How to say to samba that the client machine should load the same profile which was created when the server was up and running. I do not want the client machines to create new a profile when the server is down bcoz in windows domain, when the windows domain is shutdown, the client machines are able to login with the same profile (the profile which was created when the domain was up). I wish to have same thing in samba pdc also.
I am trying to get a mount in my root directory to a folder on a remote machine so that a log in is not required to access it. I seem to be having some problems with permissions though.
So far I have: - added the machine to my /etc/hosts file - added remotemachine:/data /auto nfs ro,soft 0 0 to my /etc/fstab - added remotemachine:/data /auto nfs rw,soft,addr=10.112.33.4 0 0 to my /etc/mtab file - added /hostmachinefolder mymachineip(rw) to the host /etc/exports file
However when I mount -a on my machine I get: mount: remotemachine:/folder failed, reason given by server: Permission denied
I have a Fedora 11 Server which act like a Internet gateway for our LAN. I have my own iptables andt squid. We daily starts up & shuts down the server. Since last few days I am facing a unique problem. When we starts the server we are able to brows the Internet on the Server but from the client machine we are unable to do so but we can ping any internet sites/Static IP from the Client machines. After 2-5 times of startup and shutdown of the Server. We are able to browse internet from the client machine.
I have looked for clues in the sshd.conf etc. But I can't really find anything that give me a hint of why fedora 14 keeps blocking my access.I get all the way into the ssh interface.
So it's not a firewall problem and the port forwarding is working fine. I am using putty to access the machine remote.Anyone have any ideas of what I need to set in ssh or sshd.conf. I am expecting to login with password not with keys.
I have had a look at the the information on the ubuntu forum about this but am having trouble getting the server to do what i want it to do.
I have a VPS running ubuntu 9.10 and i am trying to set it up to redirect port 25 to a remote machine via a VPN connection (remote machine connected via VPN)
i have tried setting this up in the firewall using webmin but it is not working.
i have a problem........ How to redirect local http port to remote ip ddress(192.168.10.64) using iptables..my destro is Centos 5.3 my rule is this iptables -t nat -A PREROUTING -s 0/0 -d <my local ip> -p tcp --dport 80 -j DNAT --to-destination 192.168.10.64
I am accessing a remote DB using JDBC from inside a java program. is there any terminal command with which I can see the remote machine's ip/mac address?
I have Fedora installed on a netbook. I customarily mount several NFS shares on this machine, from both a desktop system running F11 and a small server running FreeBSD. On the server side the shares are write-enabled. On the server side the shares are write-enabled. In the past this has worked fine.
However since upgrading to F12, my configuration no longer works as before. Reading from the NFS shares is no problem, but as soon as I try to write to one, either in Nautilus or from any other program, including on the cmd line, all hell breaks lose. Nautilus crashes, and I am unable to remount the shares. Usually rebooting the client is the my only recourse.
There are no clues in dmesg on either the client or the server. In terminal trying to remount a "trashed" share I see this:
Code: $ sudo mount -v venus:/media/disk8 /media./disk8 mount: no type was given - I'll assume nfs because of the colon mount.nfs: timeout set for Sat Feb 20 17:34:59 2010 mount.nfs: prog 100003, trying vers=3, prot=6
[Code].....
The NFS versions under F11, F12, and FreeBSD are the current ones (all updates applied).
I just started to run Fedora/Linux on my laptop... I was using XP and using putty to connect to Linux servers at work. I am assuming I can use the terminal editor supplied with Fedora to connect to remote linux server? Can I uses the terminal to connect to remote linux server? How do accomplish this?
I am at a loss. I can not access my work remote desktop via the terminal server client on my wired box running Ubuntu 10.10. My wireless laptop is able to connect right away once I established the VPN connection. The VPN connection is established on both boxes with no problems.
When I tried the Terminal Server Client on my wired boxed, it says it can not establish a connection. Yet my wireless box gets connected immediately!
I check the /etc/dhcp3/dhclient.conf and the /etc/resolv.conf to see if there were any differences, but they are essentially the same. When I have the vpnc connection, they both recognize it and I am able to ping the IP address shown when I do a "ifconfig" on the terminal.
What can be the problem? Anything I need to configure on a wired computer versus a wireless one? What else can I check?
When DNS server is configured on Windows server, it will automatically detect and catch computer names and IP address. With Linux (BIND), I have to enter each clients manual under zone file. example (computer1 IN A 10.10.1.4). is there anyway to make Linux detect client automatically as windows does?
