  • Remote server's x menus without vino, vnc etc

    - by Fredde
    A question where both google searches, as well as askubuntu and ubuntu forums searches fails though rephrasing the question a number of times. Have a Lubuntu server with some storage and functions and a lubuntu laptop. Previous when running winXP, I had Xming, could start a x-session on the server, got the lxpanel on the laptop, switching, running x-programs without a hitch though the lxpanel menu. A very neat and convenient solution. However the winXP crashed, me moving to lubuntu also for the laptop. still things work, I ssh into the server and can start x-programs without a hitch. But, as with all graphical desktops, I at times need access to the lx menus on the server to find programs and here the problems arise, most finding I got talk about installing VNC, vino etc overkills, avoiding existing X-integration between the servers. I'll like to do as I did with Xming, see the menu system on the server, in my "client's" xwin? Just to see the servers installed software without colliding with the laptop X-server, just using it as normal X-apps.

  • Locale variables have no effect in remote shell (perl: warning: Setting locale failed.)

  • I deleted all files and folders (including hidden) from /home/username/ now in big trouble

    - by jeffery_the_wind
    I am logged into a remote ubuntu server, and I accidentally erased the entire /home/username/ directory for the current user. The only thing left is a hidden directory called .gvfs. I don't need anything of the Documents/Music/etc. Now it is not letting me cd into the /var/www/ directory, which has permissions 666 and it is owned by the current user. I am afraid to disconnect from my ssh session because I don't know if I will be able to get back on. Have I permanently created a problem? Is there a way I can replace the most important files to the /home/username/ directory? Thanks! ** EDIT ** Thanks everyone for the help. I figured the problem with cd into the /var/www/ was actually my permissions in the /var/www/ directory. It was set to 666, changed it to 755 and everything was good again. It doesn't look like anything systematic was ruined by deleting the contents of the user folder.

  • Routing for Two Hosts Behind a IPSec Tunnel

    - by Brent
    Network A 10.110.15.0/24 Firewall is .1 Host A is .2 Network B 10.110.16.0/24 Firewall is .1 Host B is .2 Two Cisco ASA's. IPSec tunnel with a crypo map that secures 10.110.15.0/24 <- 10.110.16.0/24. Let's say two hosts, 10.110.15.2 and 10.110.16.2 need to talk to each other. Normally I have to enter a persistent static route on a each host along the lines of: route add 10.110.16.0 mask 255.255.255.0 10.110.15.1 metric 1 -p (on the "A" box) I also have to enter another persistent static route on the .16 host in order for the traffic to know how to get back to the .15 network. Note that the default for each machine IS the firewall, so .1. I have no problem adding persistent routes on Windows/ESX/*nux machines but what about a smart switch in the .16 network that I want to manage from the .15 network. Do I need to run a routing protocol? Do I need to have Reverse Route Injection enabled on both ends of the IPSec tunnel? Should I add a route on the firewall? If so, how do you formulate it? Does it get a metric of 1 and my default route 0.0.0.0 get a metric of 2?

  • How to route all traffic over site to site VPN tunnel?

    - by Hutch
    I have a site to site VPN configured between our main site (Site A) and a remote site (Site B). Site A is 10.60.0.0/16 Site B is 192.168.99.0/24 The firewall in Site B is a Juniper SSG running ScreenOS 6.3 and I'm using a route based VPN. The tunnel works perfectly in that from Site A you can reach 192.168.99.0 via the tunnel, and from Site B you can reach 10.60.0.0 via the tunnel. However, we want it so that if you're in Site B and want the Internet it goes via the firewall at Site A, and right now on the Juniper 0.0.0.0 has the ISP router as next hop. My understanding is that on the Juniper, I can set a route for the /32 public IP at our main site that the VPN tunnel connects to to the ISP router via ethernet0/0 (the SSG's external interface), and then modify the 0.0.0.0 route to use our main site firewall via tunnel.1 (the VPN tunnel). Not sure I've explained that so well but is my understanding correct? Thanks

  • How to set up vpn tunnel (ipsec) connection

    - by Alfwed
    I'm working with a client who wants to set up a vpn tunnel between their network and ours. They're in charge of the tunnel and to give us the access they are asking me my public IP and my LAN IP. This is what i've got when i do an ifconfig on the server i will use to connect to the vpn $ ifconfig eth0 Link encap:Ethernet HWaddr d4:ae:52:cd:xx:xx inet adr:62.210.xxx.xxx Bcast:62.210.xxx.xxx Masque:255.255.255.0 adr inet6: fe80::d6ae:52ff:xxxx:xx/64 Scope:Lien UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Packets reçus:55255032 erreurs:0 :779628 overruns:0 frame:0 TX packets:5419527 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 lg file transmission:1000 Octets reçus:5598164393 (5.5 GB) Octets transmis:1034297288 (1.0 GB) Interruption:16 Mémoire:c0000000-c0012800 lo Link encap:Boucle locale inet adr:127.0.0.1 Masque:255.0.0.0 adr inet6: ::1/128 Scope:Hôte UP LOOPBACK RUNNING MTU:16436 Metric:1 Packets reçus:45923382 erreurs:0 :0 overruns:0 frame:0 TX packets:45923382 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 lg file transmission:0 The inet adr:62.210.xxx.xxx is my public IP but it seems like i dont have any LAN IP. Can the connection work without LAN IP or should I create a private network somehow?

After some debugging, I was able to narrow it down to a few things. For some reason the sshd daemon is running as root:www-data (apache user) instead of root. My ftp connection works but ssh over terminal fails. I have no idea whether it is getting caused due to suPHP or not (because that is the only place where user permission's etc. change). I really need to narrow it down and fix it asap. Thanks a lot!

  • Connecting git to github on windows 7 without bash

    - by George Mauer
    I'm setting up git on my new Windows 7 machine and I'm hitting a roadblock when it comes to getting github to acknowledge my ssh key. I am doing things a little different from the standard script in that I would rather not use cygwin and prefer to use my powershell prompt. The following is what I did: I installed msysgit (portable). I went to C:\program files\git\bin and used ssh-keygen to generate a public/private ssh keypair which I put in c:\Temp I then created a directory named .ssh\ in c:\Users\myusername\ (on windows 7) I moved both the files generated by the ssh-keygen (id_rsa and id_rsa.pub) into the .ssh directory I went to my account on github, created a new public key, copy-pasted the contents of id_rsa.pub into it and saved I now go to my powershell prompt, set-alias git 'C:\program files\git\bin\git.exe' I try to now do a clone [email protected]:togakangaroo/ps-profile.git which rejects my authentication: Permission denied (publickey). fatal: The remote end hung up unexpectedly Past experience says that this means git is not recognizing my key. What steps am I missing? I have a feeling that I need to somehow configure git so that it knows where my ssh keys are (though it would seem it should look there automatically) but I don't know how to do that. Another possible clue is that when I try to run git config --global user.name "George Mauer" I get an error fatal: $HOME not set I did however set up a HOME environment user variable with the value %HOMEDRIVE%%HOMEPATH%

Any advises are welcome. btw, I have read first 3 pages on google about this problem.

  • I Cannot connect to remote MySQL database using SSH tunnel

    - by Scott
    Brand new server, brand new MySQL 5.5 install on Ubuntu 12.04. I can log in to the database as root from the command line. I can log on via Navicat MySQL or Sequel Pro as root on port 3306 from my Mac. I cannot log in using an SSH tunnel to the server and then to the database as root. I have tried both localhost and 127.0.0.1 as server for the local connection part. My password is fine. root is currently defined at %, 127.0.0.1, and localhost. I have set up this same type of connection at least 30 times before and never had a problem. The SSH connection gets made with no problem, and then it just hangs trying to connect to the DB and finally times out. The only thing I changed in my.cnf was to comment out the bind-address = 127.0.0.1 line. Any help? Any Ideas?

  • IPv6 tunnel broker setup

    - by fred basset
    I'm working on a solution to allow remote Linux nodes that are behind firewalls to be accessible for SSH and web server. Can anyone suggest an IPv6 tunnel scheme that would work with NAT firewalls? And what software would be needed on the remote nodes and the central server? Also I do not believe the ISP at either side does native IPv6. A solution where we could have static IPv6 addresses on the remote Linux nodes would be ideal. Thank you, Fred

  • Remote Debian System Preventing Logon

    - by choobablue
    I have a dozen or so single board computers on a network running Debian (squeeze) and access them via ssh (ssh server is dropbear). To give an idea of the hardware of these computers they're 1.2 GHz x86 processors, 1GB of RAM and 4GB flash drives formatted as ext2 (I avoided ext3 to prevent the added flash write stress from journaling), there is also a swap partition on the drive. Normally the setup I'm using works great and I can access all the computers. Every once in a while one will prevent access. What happens is I try to connect via ssh (putty) and it gives me the login prompt, I enter the username and password and it responds 'Access Denied' and it will also refuse any public key in ~/.ssh/authorized_keys. The credentials are correct as they worked previously. The computer responds to pings and putty recognizes the server public key, which implies to me the system is still running. Restarting the server fixes the problem and I can log in again. (I tried a temporary fix of putting shutdown -r now in the root crontab but this doesn't seem to reliably be run once the hang happens) Once I restart however there doesn't seem to be any information in any of the system logs to indicate what happened, the logs are simply empty for that time period, as if the system had crashed. There is some custom software running on the system which appears to stop working (which is why I wanted to ssh to begin with). I'm assuming that this program is the source of the problems but I'm unsure of how it would cause it and how to debug what is happening. The most likely explanation I can think of is that there is a memory leak in the other program that then prevents dropbear from spawning a new login shell (and crontab from executing shutdown) as there is not enough free memory. But looking at memory usage of the other (working) computers there doesn't seem to be any meaningful increase in memory to indicate a leak (unless it's a very big, fast acting and rare leak). I would think that when the OS ran out of memory it would restart the system or kill processes (the Linux kernel restarts right?). The other thing I wonder about is if the fact that they are running off a flash drive could have some effect, especially the swap partition (which I think I should remove to prevent wear of the flash), but the flash drives are young (~1 month) and I don't think that wear would be a factor yet. Does anybody have an idea of what could cause these symptoms, if it could be done by a memory leak, or something else I haven't thought of. And does anybody know of a method to try to debug the problem and find out more information about what's going wrong?

  • Remote Scripted Installation of Sun/Oracle JRE

    - by chrisbunney
    I'm attempting to automate the installation of a Debian server (debian 6.0 squeeze 64bit). Part of the installation requires the Sun JRE package to be installed. This package has a licence agreement, which has to be accepted. I have a script which uses the following lines to accept and install the JRE: echo "sun-java6-bin shared/accepted-sun-dlj-v1-1 boolean true" | debconf-set-selections apt-get install -y sun-java6-jre This works fine when executing the script locally. However, I need to execute the script remotely using the ssh command, e.g.: ssh -i keyFile root@hostname './myScript' This doesn't work. In particular, it fails on apt-get install -y sun-java6-jre. It would seem that in spite of me setting the licence agreement to accepted, when run remotely in this manner it is ignored. Despite setting the value to true, I still get prompted to manually accept the agreement when I run this command: ssh -i keyFile root@hostname 'apt-get install -y sun-java6-jre' I suspect it is something to do with environment that is taken care of when running a proper terminal session, but have no idea what to try next to fix it. So, what do I have to do to get this command (and hence my deployment script) to run correctly when executing it remotely? Or is there an alternative way that allows me to install the JRE remotely by another means? Edit 0: I have compared the output of env when executed remotely via ssh and when executed via a local terminal session. The only difference between the outputs is that the local terminal session has the additional value TERM=xterm.

  • Enable PasswordAuthentication on OpenSuse 10

  • Kerberos & localhost

    - by Alex Leach
    I've got a Kerberos v5 server set up on a Linux machine, and it's working very well when connecting to other hosts (using samba, ldap or ssh), for which there are principals in my kerberos database. Can I use kerberos to authenticate against localhost though? And if I can, are there reasons why I shouldn't? I haven't made a kerberos principal for localhost. I don't think I should; instead I think the principal should resolve to the machine's full hostname. Is that possible? I'd ideally like a way to configure this on just one server (whether kerberos, DNS, or ssh), but if each machine needs some custom configuration, that'd work too. e.g $ ssh -v localhost ... debug1: Unspecified GSS failure. Minor code may provide more information Server host/[email protected] not found in Kerberos database ... EDIT: So I had a bad /etc/hosts file. If I remember correctly, the original version I got with Ubuntu had two 127.0. IP addresses, something like:- 127.0.0.1 localhost 127.0.*1*.1 hostname For no good reason, I'd changed mine a long time ago to: 127.0.0.1 localhost 127.0.*0*.1 hostname.example.com hostname This seemed to work fine with everything until I tried out ssh with kerberos (a recent endeavour). Somehow this configuration led to sshd resolving the machine's kerberos principal to "host/localhost@\n", which I suppose makes sense if it uses /etc/hosts for forward and reverse dns lookups in preference to external dns. So I commented out the latter line, and sshd magically started authenticating with gssapi-with-mic. Awesome. (Then I investigated localhost and asked the question)

  • rhel configure: limit root direct login to systems except through system consoles

    - by zhaojing
    I have to configure to limit root direct access except system consoles. That is, the ways of telnet, ftp, SSH are all prohibited. Root can only login through console. I understand that will require me to configure the file /etc/securetty. I have to comment all the tty, just keep "console" in /etc/securetty. But from google, I found many peoples said that configure /etc/securetty will not limit the way of SSH login. From my experiment, I found it is. (configure /etc/securetty won't limit SSH login). And I add one line in /etc/pam.d/system-auth: auth required pam_securetty It seems root SSH login can be prohibited. But I can't find the reason: What is the difference of configure pam_securetty and /etc/securetty? Can anyone help me with this? Only configure /etc/securetty could work? Or Have I to configure pam_securetty at the same time? Thanks a lot!

  • Using Windows as a gateway to the internet

    - by James Wright
    My customer currently blocks outbound RDP and SSH, which means that none of their employees can get access to external Windows and Linux boxes (at the console level). However, a need has recently arisen to give access to an assortment of RDP and SSH endpoints scattered throughout the internet. The endpoint IP addresses are a moving target, and an access list exists to define what those IP addresses are. So now my customer wants to have a single Windows Server that they control as the sole outbound point for RDP/SSH to the internet. Consider it a jump box to the internet. If one of our admins have an access to this Windows box then they can log on, and from there bounce around to RDP/SSH endpoints on the internet. Is a standard Windows 2008 box going to work as a jump box? For example, I seem to recall that Win2k8 limits the number of users that can log on simultaneously, which means that the jump box may not be accessible if lots of users are on it. Advice as to how to make this work..?

  • Rsync root files between systems without specifying password

    - by xpt
    This seems very tricky to me. I've set up my two systems so that I can rsync files between them as me, without specifying password. Now the the problem is to rsync files that belong to root. On both of my systems, there are no root passwords. The only way to become root is via sudo. So I can neither give a password for sudo rsyn local root@remote:, no use my ssh-agent to supply pass phrase. I don't want to set up a root password on any systems; and I do need the files to be owned by root on both systems. EDIT: Using the files that belong to root is just an example, I need a way for my unprivileged account to read/write system (including root-owned) files easily. One example is to copy my configured /root environment into the freshly-installed system. The two systems are actually two VMs under a single host, so it's not a big concern for me to copy root-owned files between them. EDIT 2: If I only want to copy my configured /root environment into the freshly-installed system, I can use tar: sudo tar cvzf - /root | ssh me@remote sudo tar xvzf - -C / But I do need rsync to update from time to time. Any easy way to make it happen? EDIT 3: Formally formulate the question Alright, it all began with the question, how to rsync files that belong to root between two systems as a normal unprivileged user, without specifying password, under the condition that, The root account is locked on both of systems. I.e., there are no root passwords. The only way to become root is via sudo (recommended security practice, see http://help.ubuntu.com/community/RootSudo) I don't want a completely passwordless sudo but don’t want to be typing passwords all the time either. The normal unprivileged user has entered their ssh pass phrase into the ssh agent. Thanks

  • Route specific HTTP requests through pfSense OpenVPN

    - by DennisQ
    Hi, to start, I have very little knowledge on routes, iptables, etc. That said, here's what I'm trying to accomplish and where I think I'm stumped: Problem: We have an external website which we recently firewalled so it only accepts traffic from our office IP addresses. This works well at the office, but doesn't work for remote access through VPN as we don't route all traffic through OpenVPN. I would rather avoid forcing everyone to route all traffic through just to accommodate this one site. Environment: Main router box is running pfSense. Em0 is internal IP, Em1 is external. Internal net is 10.23.x and VPN is 10.0.8.0/24 I believe what I need to do is add a route to the VPN server config to send all traffic to that IP over the VPN tunnel. I think that part's working, but I don't get a response back, so I'm assuming that I need some NAT config on the VPN server to route the response back over the tunnel? What I've found so far is to try the following, but since this is a pfSense box on FreeBSD, I can't run iptables, etc. Make sure ip forwarding is enabled: echo 1 /proc/sys/net/ipv4/ip_forward Setup NAT back out: iptables -t nat -A POSTROUTING -s 10.0.8.0/24 -o em0 -j MASQUERADE Am I on the right path, and if so how do I accomplish this through pfSense UI or FreeBSD CLI? Thanks!

  • Vagrant ssh fails with VirtualBox

    - by lukewm
    vagrant up fails when it gets to the ssh part: myterminal$ vagrant up [default] VM already created. Booting if its not already running... [default] Running any VM customizations... [default] Clearing any previously set forwarded ports... [default] Forwarding ports...

Please verify the VM successfully booted by looking at the VirtualBox GUI. Then when I subsequently try and connect using vagrant ssh or vagrant reload or similar, I get this: myterminal$ vagrant reload [default] Attempting graceful shutdown of linux... SSH connection was refused! This usually happens if the VM failed to boot properly. Some steps to try to fix this: First, try reloading your VM with `vagrant reload`, since a simple restart sometimes fixes things. If that doesn't work, destroy your VM and recreate it with a `vagrant destroy` followed by a `vagrant up`. If that doesn't work, contact a Vagrant maintainer (support channels listed on the website) for more assistance. Please help! I'm really stumped. Kind regards, Luke
