Networking :: Can't SSH From Gnome Terminal To Any Machine - Router

Jan 5, 2010

I have WiFi router at home and connected two computers running ubuntu linux connected to it. One connected through WiFi, second through LAN. So what is the problem: I can't SSH from Gnome terminal to any machine. Be it local computer on the same router or be it distant computer. SSH session hangs just after successful login. I've read a lot about it and it should be related to DNS, MTU or whatever, but not in my case ! PuTTY client works without problem to local or to distant PC. SSH session from Gnome terminal works also just fine if.... I connect two comupers directly by not using router. So it seems SSH installation is ok, configuration is ok, but somehow router is not ok. I looked at packet sniffer of router itself and I see that packets successfully go from one computer to router and then to other computer and returns back. Firewall working ok. And its not about packet forwarding because I have the same problem if I try to SSH to router itself.

So the question. What theoretically might be wrong with router packet management ? Why PuTTY and Gnome terminal SSH packets differs ? What is the difference ? Where should I search for some sollution? I ran SSH in debug mode, but it was no so informative. It successfully logins and hangs on this line: Code: channel 0: open confirm rwindow 0 rmax 32768

Ubuntu Networking :: Access SSH Machine Through Router?

Nov 15, 2010

I have two laptops with me here at school, one bigger one [home computer], and one smaller one [netbook]. I take the smaller one with me to class and when I'm out and about, however, I keep all of my things on the bigger one. I would really like to be able to set up some sort of SSH port forwarding for the bigger machine so that, when I'm out and I realize I left file X on my home machine, or I want to listen to a certain song, or whatever, I can just scp it to the netbook. The issue is, at my dorm, I'm stuck behind a firewall and can't just set up a SSH daemon and port forward through the router, I need a more clever solution. I do have a home server (not with me at school), which I commonly use for transferring files. Basically, I'm wondering if there is some way I can SSH into my server box, with reverse port forwarding so that, when I am out and about, I can just log into my server and copy files from my home computer for use on my netbook. I've tried a couple of solutions which come up from google "reverse ssh" but haven't been able to get them to work. A step by step guide to doing this would be great. Again, the setup is:

Home server [ssh-able]
Home Computer [behind firewall, can't ssh into at the moment]
Netbook []

Want to be able to SSH from Netbook to Home computer, probably using Home server.

Ubuntu Networking :: Use Machine As Wireless Router?

Jun 10, 2011

i did googled for that for a while now, but didn't found anything relevant so far, or did i missed something? i need to share a pppoe connection, using an infrastructure wifi network, how can i do that in ubuntu?

forgot to mention, ad-hoc just won't do it for me, the other devices, either dosen't support it, either get a password error. also, i would need some help for establishing the pppoe, i previously did that on another machine, but that was long ago, and it was a big head ache, it would only dial on startup, and no redial or disconnect posibilities whatsoever.

I have three machines say A B and C. I want to make machine B as a router for A and C, so that the ping packets from C to A should be going via B. I have directly connected two interfaces(eth4) of A and B and similarly two interfaces(eth5) of B and C. I have even set up a route between B and C. 1. But I am not able to set a route between B and A.2. If I ping A from eth4 of B(viceversa) it works. When I ping B from eth5 of C it work but not the viceversa.3. Also, if I ping from C to A, B receives the packets, but not A.

Ubuntu :: Bash Broken, Lost Functionality In Terminal (gnome-terminal)?

Dec 10, 2010

Linux-goers. I did some research on this, but I am still fairly new to Linux. In Ubuntu 10.10 (Maverick), I accidentally overwrote my "/bin/bash" file. Dude, using "sudo" with a small typo can work disasters. Bash is now broken in the Terminal (gnome-terminal). Terminal itself still works fine, technically, but bash is still hosed/broken. Here is what I did to try to fix it: Booted from Ubuntu 10.10 live CD. Mounted my Ubuntu partition and manually copied the good/fresh "bash" file onto my hard drive. Verified copy was successful. Didn't help, as you see. Reinstalled "gnome-terminal" using synaptic package manager. Tried to reinstall bash via synaptic, it failed with error, "E: /var/cache/apt/archives/bash_4.1-2ubuntu4_i386.deb: subprocess new pre-removal script returned error exit status 2"

In Terminal, all basic commands work as far as I can tell. ("ls", "pwd", navigation, etc.) Here are some problems:My "username@computername" does not display in the prompt; only the $ sign. Bash keyboard shortcuts such as uparrow and tab do not work. Instead, each inserts a key code. I can't even move the cursor left/right. Aliases (a function of bash and .bashrc) are broken, of course. My sanity level decreases when I use Terminal now. For what it's worth, even with "sudo" I get a "permission denied" error when trying to run Google Chrome! I read something about a ".bashrc" file being a possible problem, but I don't know how to make it work, or the file's proper locations in Ubuntu 10.10. Is there something I can do with a "make" or "apt-get install" command or something?? Could this simply be a permissions problem? Is the link to "/bin/bash", "/bin/sh", or a ".bashrc" file broken? Guide me, oh Linux gurus.

P.S. I always wondered what exactly bash was and how it was different from the basic terminal. LoL, this is an excellent way to demonstrate the difference, and I WANT IT BACK!

Ubuntu :: Can't Turn On Terminal Bell In Gnome-terminal Using Remote Screen Session With Irssi

Nov 6, 2010

I'm using 10.04, and gnome-terminal GNOME Terminal 2.30.2 . I have irssi running on screen session on remote host. And I've been struggling for quite many days to configure it to produce either visual feedback or ring terminal's bell when I receive a private message or one of those that are highlighted.

My compiz settings window in General tab has 'Audible bell' checked.

My GNOME terminal has 'Terminal bell' checked.

I also added 'set bell-style audible' to my ~/.inputrc

And I also tried to manually load pcspkr module into my kernel.

No of the above helped or at least I haven't been able to notice any difference.

I also used some commands for irssi to produce bell sign.

OpenSUSE Network :: Nfs/Nis Using OS 11.3 Machine As Router

Dec 2, 2010

I had an OS 11.3 machine running as an Nis server with Nfs, also providing dns, squid, samba shares and running apache

Internet connection provided by a netgear router at 192.168.0.1, server at 192.168.0.2, clients at 192.168.0.3, 192.168.0.4, etc. The clients all being configured to use the server for dns the squid running on it for their proxy, logging on with Nis using the exported server's Nfs /home share as /home on the clients

Everything was setup through Yast with some conf file editing being done later for samba and apache and all working brilliantly

Until ...

I added another network card to the server machine and set it up as a router, where they will be placed once ready the router providing the internet connection doesn't have gigabit ethernet

So I figured if I had gigabit cards in the clients and a gigabit card in the server set up for the internal zone and providing routing, then the clients using it as their router the local stuff would be more responsive, especially as they are using an nfs share for /home

I set the clients up to use the server at 192.168.1.1 for their router and changing their own local ip addresses to suit, i.e. 192.168.1.2, 192.168.1.3 etc and rebooted

Nis and nfs were no longer working, so I logged on as the local user, ecky, who's home directory isn't in the nfs share but at /ecky, the internet connection worked fine and so did everything else, dns, proxy, etc

I tried changing the nfs share and nis server to the internal card's ip, 192.168.1.1 and that didn't work either

Samba shares work at both 192.168.0.2 and 192.168.1.1, so my problem is that nis logons and nfs mounts don't work from either address

I've tried to give as much info as possible on what I've done without being too confusing ... don't know whether I succeeded

Darned annoying cos it took me a day and a half to get the gigabit card to detect properly in one of the machines...

Networking :: Setting Up Linux Box As IPv6 Router To Replace Netgear WNR1000 Wireless Router?

Jun 18, 2011

I want to set up a Linux box as a wireless router to replace our existing Netgear WNR1000 router, as I believe the Netgear does not support the coming IPv6 protocol. Unfortunately, it is not flashable with OpenWRT or DD-WRT presently.

As we have Comcast, our cable modem acts as a dumb modem according to the customer support guy I talked to, and our router is the one that asks for the IP address from DHCP. Thus, when Comcast switches over to IPv6, I don't believe my existing router would work, correct?

My idea is to take a Linux box and put two NICs and a wireless adapter in it, using IPCop or Smoothwall to set up a router. I could then enable IPv6 support for when we have IPv6 with Comcast. Is that possible? Would there be a way to get BIND to hand out private IP addresses in the same subnet on the both the LAN NIC and the wireless card?

Networking :: Set Up A Laptop As A Router To Connect Wirelessly To ADSL Router?

Nov 6, 2009

I have a desktop PC running Ubuntu 9.10 and Windows 7, and a Eee PC 701 laptop running EasyPeasy Ubuntu 9.04. I'd like to connect the desktop to the laptop with a wired connection (eth0), then the laptop to my ADSL router using wireless (ath0).

I have a crossover ethernet cable (I bought on ebay). I have set up my laptop with a static IP address on my LAN and it uses OpenDNS.

I have added this to /etc/sysctl.conf on the laptop:

net.ipv4.ip_forward=1

Then I tried this on the laptop:

sudo iptables --table nat --append POSTROUTING --out-interface ath0 -j MASQUERADE
sudo iptables --append FORWARD --in-interface eth0 -j ACCEPT

This is a variation on what I found on other sites describing how to set up a router. I don't understand iptables very well, but I gather that the above two lines should set up forwarding so that traffic from my router to the laptop will be forwarded to the desktop, and vice versa.

But this doesn't work. The connection doesn't even establish between the laptop and the desktop.

Networking :: Network Setup - Router - Wireless Router Card ?

Apr 24, 2010

I'm having trouble getting my network set up the way that I want it/had it. You see, when I first set up my network, I just had my cable modem going directly to my standard wired router (A D-Link DI-604), which had DHCP,and was connected to all of the computers on my network. I had one switch hooked up to one of the ports of the router, but this was a regular switch, and it would not try to assign IP addresses, it would just pass through the DHCP info as I wanted.

Now however, my network setup has changed. My room mate and I both got laptops, and we decided that we wanted to have wireless access so we didn't have to constantly plug in to the router.

Now my network is set up like this: The modem is hooked up to the router(DI-604), which is hooked up on the LAN side to our computers, our switch (which is hooked up to 3 more computers), and to a wireless router card (A Gigabyte GN-BC01).

The wireless router card has two jacks for ethernet. One for WAN, and one for LAN. The LAN side we have plugged only into the computer in which the card is installed.

Now the problem is this: The wireless router card comes with DHCP by default, and it's assigning addresses to the laptops and to the computer hat it's in, and worse, the IP addresses are on a different subnet than that of the main dlink router. The Main (dlink) router assigns addresses from 192.168.0.1 (itself) to 192.168.0.254, while the wireless router card assigns addresses from 192.168.1.1 to 192.168.1.254 (itself).

Because of this, I cannot access services on the wireless network from my wired network or vice versa. The first thing I tried was setting the card to assign addresses from 192.168.0.12 to 192.168.0.253, however it just said "internal error" when I tried to do this. I decided that this may be because it sees that it was being assigned an address on it's WAN side on the same subnet. So the next thing I tried was disabling DHCP and setting the "LAN IP Address" to 192.168.0.12, hoping that the DHCP would just go through the card, like a switch. I would have set the LAN IP address to be assigned by DHCP, but this was not an option, so I decided that'd be the best thing to set it to.

Once again however, setting the LAN ip address to an address on the same subnet as that of the IP assigned to it's WAN side caused it to report an "internal error". I verified that this was the issue by setting the LAN address to several other private IP addresses to test (I.E. 10.0.0.1, 192.168.3.1, 192.168.5.12).

My question then really is: How do I set up both routers so that I can access services and computers from each network from the other network. Should I set them with different subnets and set the gateway on the wireless network to the main router? To the wireless router card? Should I put them on the same subnet? Will it know how to communicate?

Here is a link to (picture) my network diagram. Network Diagram

Debian Multimedia :: Xcompmgr 'master' - Rounded Window Borders Don't Draw And Redraw Properly When Using The Terminal (gnome-terminal And The LXDE And Xfce Ones)

Aug 26, 2011

I find xcompmgr more than adequate for making a desktop look pretty modern, and I don't like the more extravagentCompiz gimmicks - but there is one thing that irritates when using xcompmgr which someone here might have worked round.

Rounded window borders don't draw and redraw properly when using the Terminal (gnome-terminal and the LXDE and Xfce ones) or system monitor and moving them from their default place. You get this little white botch at the corners. I'm not massively technical and I'm ambivalent about how much more I want to learn as I have plenty of creative outlets already, but I would like to solve this. Somehow xcompmgr is treating these programs as a different class? It's capable of drawing the window borders properly as it is just these two programs that get botched. Possibly this doesn't get noticed as maybe people usually use xcompmgr with openbox and LXDE and their square window borders. I did do a search but there was nothing matching what I saw.

Ubuntu Security :: Stopped Forwarding All Ports To Machine In Router

Mar 1, 2011

This morning I was looking at the router's log file and noticed a certain IP address was able to gain LAN access on port 2222. That just happens to be the port my SSH server is listening on! A whois search revealed that IP address is in Germany. As soon as I found this out I stopped forwarding all ports to this machine in my router.

how to tell what had happened, what information this person was able to obtain, and if he left any goodies behind that could hurt me? I've read through some of the logs on my computer and haven't been able to find much at all. I did have some personal information on the hard drives, but that information is encrypted. I'm thinking if they were able to get my SSH password then that information probably isn't safe either (assuming they have some of it).

Networking :: Old Router Behind New Router - Configuration ?

Oct 30, 2010

I've moved a linuxbox from being my gateway (nat, etc) to behind a new gateway (a DD-wrt router). For transparency purposes, I'd like to continue using the old box services, and just have the gateway in front of it.

Here's what I did:

The newgateway is setup for class C, 192.168.0.0

This configuration works, but sometimes it doesn't and I haven't figured out why yet.

At sometimes, clients on the LAN get throughput rates with very little speed loss (using speakeasy speed test). They will run at 33M on the LAN, running through both the newgateway, and the oldbox, and get about 35M with directly connected to the cable modem.

Other times, it seems nothing can talk with anyone, and I am not sure why.

I know what I have done is a little unconventional, but it's a transitional thing, and I am not sure it is the cause of the problem, although it was the last things changed.
