  • what's the difference between /etc/init.d/sshd start and /usr/sbin/sshd?

    - by jasono
    I'm having issues with passwordless ssh. I've checked, double checked and checked again that I have everything set up correctly. Both machines are RHEL6 and when the destination machine first boots up passwordless ssh does not work. If I stop ssh (service sshd stop or /ect/init.d/sshd stop) and then start it directly (/usr/sbin/sshd) passwordless ssh works fine. If I start ssh via the service (service sshd start or /etc/init.d/sshd start) passwordless ssh does not work. Just for testing I've tried commenting out the entire start() function in /etc/init.d/sshd and replace it with /usr/sbin/sshd - that still fails to allow passwordless ssh. I believe that this means that something in the /etc/init.d/sshd file is causing the screw up but I don't know enough about linux to narrow the issue down.

  • What ufw allows/denies by default?

    - by mgibsonbr
    I was accessing a server running Ubuntu 12.04 Server using SSH and managed to lock myself out of it. I'm still wondering how that happened: The firewall was enabled by default; sudo ufw status did not show any rules (but I could SSH to the server normally); I tried explicitly allowing ports 80 and 443 using the commands: sudo ufw allow 80 sudo ufw allow 443 sudo ufw status now showed something like: Status: active To Action From -- ------ ---- 80 ALLOW Anywhere 80 ALLOW Anywhere (v6) 443 ALLOW Anywhere 443 ALLOW Anywhere (v6) (Recalling from memory and seeing some examples; I can't access the server to see the exact output, so I might be mistaken) After logging out of SSH, now I can't log in anymore (connection timeout). What just happened? There were no DENY rules previously (AFAIK), neither I introduced any. How could SSH be previously available and now it's not? Does ufw (or more precisely iptables) allow everything by default, unless you explicitly allow something, then it denies everything by default? Or did I do something wrong, that broke the existing rules somehow?

  • Security Pattern to store SSH Keys

    - by Mehdi Sadeghi
    I am writing a simple flask application to submit scientific tasks to remote HPC resources. My application in background talks to remote machines via SSH (because it is widely available on various HPC resources). To be able to maintain this connection in background I need either to use the user's ssh keys on the running machine (when user's have passwordless ssh access to the remote machine) or I have to store user's credentials for the remote machines. I am not sure which path I have to take, should I store remote machine's username/password or should I store user's SSH key pair in database? I want to know what is the correct and safe way to connect to remote servers in background in context of a web application.

  • Is there any way to abstract IP address during ssh?

    - by Vivek V K
    I have a server which is in the middle of a forest. It is connected to the Internet via a microwave link and an ADSL link.Hence it has two different static IP addresses. Now if there is heavy rain, the microwave link breaks and I should use the much slower ADSL link. And I ping the microwave ip time to time to check if it is up again . But at times, I end up using the very slow ADSL link even if the microwave link is back up. Hence I need a way to automate this in the following way. 1.I need to abstract the IP address of the machine with some other name which when I use ssh or sftp, will poll both the IP and connect me to the best one. so for eg: if I say ssh -Y name@server, It should first try to connect to the microwave link if it cant, then connect to ADSL. 2.Suppose the first time I connect, the microwave link is down so it connects to ADSL, I need it to dynamically change to the microwave link once it is working again. Is this even possible?

  • How do I get the F1-F12 keys to switch screens in gnu screen in cygwin when connecting via SSH?

    - by Mikey
    I'm connecting to a desktop running cygwin via SSH from the terminal app in Mac OS X. I have already started screen on the cygwin side and can connect to it over the SSH session. Furthermore, I have the following in the .screenrc file: bindkey -k k1 select 1 # F1 = screen 1 bindkey -k k2 select 2 # F2 = screen 2 bindkey -k k3 select 3 # F3 = screen 3 bindkey -k k4 select 4 # F4 = screen 4 bindkey -k k5 select 5 # F5 = screen 5 bindkey -k k6 select 6 # F6 = screen 6 bindkey -k k7 select 7 # F7 = screen 7 bindkey -k k8 select 8 # F8 = screen 8 bindkey -k k9 select 9 # F9 = screen 9 bindkey -k F1 prev # F11 = prev bindkey -k F2 next # F12 = next However, when I start multiple windows in screen and attempt to switch between them via the function keys, all I get is a beep. I have tried various settings for $TERM (e.g. ansi, cygwin, xterm-color, vt100) and they don't really seem to affect anything. I have verified that the terminal app is in fact sending the escape sequence for the function key that I'm expecting and that my bash shell (running inside screen) is receiving it. For example, for F1, it sends the following (hexdump is a perl script I wrote that takes STDIN in binmode and outputs it as a hexadecimal/ascii dump): % hexdump [press F1 and then hit ^D to terminate input] 00000000: 1b4f50 .OP If things were working correctly, I don't think bash should receive the escape sequence because screen should have caught it and turned it into a command. How do I get the function keys to work?

  • Keyring no longer prompts for password when SSH-ing

    - by Lie Ryan
    I remember that I used to be able to do ssh [email protected] and have a prompt asks me for a password to unlock the keyring for the whole GNOME session so subsequent ssh wouldn't need to enter the keyring password any longer (not quite sure if this is in Ubuntu or other distro). But nowadays doing ssh [email protected] would ask me, in the terminal, my keyring password every single time; which defeats the purpose of using SSH keys. I checked $ cat /etc/pam.d/lightdm | grep keyring auth optional pam_gnome_keyring.so session optional pam_gnome_keyring.so auto_start which looks fine, and $ pgrep keyring 1784 gnome-keyring-d so the keyring daemon is alive. I finally found that SSH_AUTH_SOCK variable (and GNOME_KEYRING_CONTROL and GPG_AGENT_INFO and GNOME_KEYRING_PID) are not being set properly. What is the proper way to set this variable and why aren't they being set in my environment (i.e. shouldn't they be set in default install)? I guess I can set it in .bashrc, but then the variables would only be defined in bash session, while that is fine for ssh, I believe the other environment variables are necessary for GUI apps to use keyring.

  • How To Remotely Copy Files Over SSH Without Entering Your Password

    - by YatriTrivedi
    SSH is a life-saver when you need to remotely manage a computer, but did you know you can also upload and download files, too? Using SSH keys, you can skip having to enter passwords and use this for scripts! This process works on Linux and Mac OS, provided that they’re properly configured for SSH access. If you’re using Windows, you can use Cygwin to get Linux-like functionality, and with a little tweaking, SSH will run as well.What is a Histogram, and How Can I Use it to Improve My Photos?How To Easily Access Your Home Network From Anywhere With DDNSHow To Recover After Your Email Password Is Compromised

  • How to run a GUI app from ssh shell?

    - by karramba
    I can access my linux box by ssh and by vnc. I want to run a GUI application, but directly from ssh, I don't want to access through VNC and click around. So, after logging in using ssh, I want to issue a magic command, so that when I log in through VNC I will see my GUI app running. How can I do this?

  • How do I mount a remote Linux folder in Windows through SSH?

    - by Jared
    I'm a blind student currently in a system admin/shell programming class. Although ssh works fine for executing commands like ls, pwd, etc editors do not work well with my screen reader and an ssh session. I was wondering if it is possible to mount a Linux folder over ssh so it appears as a windows drive? This way I could edit any files I needed to with accessible software and not have to constantly use SCP to send files back and fourth.

  • chef clients behind firewall

    - by tec
    I am currently learning about chef. What I understood so far: I have to install chef-server on an own server or use the hosted chef. I have to install chef-client on the servers that I want to manage aka nodes (manually or using knife bootstrap). I installed several chef tools on my own PC that I can use to manage the nodes, e.g. knife. Now in my case the specialty is that the nodes are behind a firewall/load balancer/proxy. The nodes can access servers on the outside via NAT (http works and I can configure chef-specific hosts to work as well). However they can only be contacted from the outside via a ssh tunnel. There is really much documentation about chef available but I did not find an answer to these questions: When using knife, is it enough when I set up a ssh tunnel manually on my own PC or does the chef server need to contact the nodes? When using knife, can I configure it to setup a ssh tunnel automatically? When using the chef server web ui can I configure it to connect to the nodes via ssh tunnel or do I need a setup where I setup the tunnel myself e.g. using monit? Is this even possible with hosted chef? Instead of using knife or the web ui: Can I issue the same management commands directly on the nodes using chef-client? What solution would you recommend? Thanks a lot for taking your time to help and answering one or more of these related questions

  • How to port forward https traffic via ssh and/or remote desktop to through several networks and PCs?

    - by donttellya
    I have the following environment: In company X I develop a application on a pc A in network A with ip address 192.168.100.50 which has to do an https request to an http server located in the intranet of company Y In company X is another pc B in network B with ip address 192.168.200.100 pc B (of company X) can access the intranet from company Y via ssh tunnel (putty) pc A (of company X) can ping pc B (of company X) note: pc A can also do a remote desktop connection to pc B) pc B can ping the http sever pc A can not ping the http server How can the https request from pc A of company X get to the http server of company Y? On which pc must be putty configured? And which settings for host, port forwarding etc. has to be done in putty? So finally the https request should go from PC A - PC B - Http Server in company Y.

  • Autossh startup on Ubuntu 10.04 - fails after powering off

    - by grant
    I'm using upstart to keep a reverse ssh tunnel alive using auto ssh similar to Using Upstart to Manage AutoSSH Reverse Tunnel. This works fine, except after a manual power down I can no longer connect to the machine through the "central server" using the tunnel. I receive "ssh_exchange_identification: Connection closed by remote host". The autossh process is running on the client. I can connect again after re-starting networking. I'm trying to figure out why this is failing consistently after a manual shutdown. Is it possible that I need to do some cleanup on startup that would allow the tunnel to work in this situation, or are there some other debugging/troubleshooting steps I can take to determine the problem? Machine A is the client machine, using autossh. This machine sits behind a firewall and uses the following command in upstart to create an ssh tunnel: /usr/bin/autossh -fN -i /keyfile -o StrictHostKeyChecking=no -R 20098:localhost:22 user@centralserver Machine B we'll call the "central server", which sits in the cloud and is the host. This machine is "centralserver" in the command above. When Machine A is hard powered off, and back on, I cannot connect to it by SSH'ing from my machine (C) to Machine B in the cloud, then using the following command to get to Machine A: ssh -p 2098 user@localhost Again, after a reboot of the client (A), this works fine. It is only after a hard power down that the problem occurs. There are autossh processes that are running on the client machine (A) after powering down and back up, but they just don't seem to doing their job.

  • how to know which display number for the variable DISPLAY to be exported when ssh to server

    - by insidepower
    When i ssh to server using -X, i always confuse about which display number i should export. It seems to me sometimes the display number has been used by something, so what i can do is only export DISPLAY=localhost:0 && xclock export DISPLAY=localhost:1 && xclock export DISPLAY=localhost:2 && xclock export DISPLAY=localhost:... until the clock appear. Then i will use that display number. Each time log in to the server, the display number which is able to tunnel the gui data correct would be different. I know many of such similar questions has been asked and answer. However I couldn't find answer to my question, anyone know about it? Thanks!

  • How do I check if a process (Firefox) has quit?

    - by Al_Jehle
    I am using Ubuntu 12.04 64-bit, with all updates installed. I made a simple shell script that starts a SOCKS5 tunnel and launches Firefox (with correct network proxy settings) to use the tunnel. How do I recognize when Firefox has ended (when I close it) so that I can close the tunnel? Also, it would be awesome if I could run this in the background, but not necessary. #!/bin/sh ssh -fCN -D 10000 server.com firefox //To lauch firefox using Ubuntu ? Code to determine when firefox has quit Code that kills the tunnel

  • Can't connect to a remote server with Nautilus and a private key

    - by Desmond Hume
    The remote server requires a private key and passphrase for authentication. I tried putting username@server in the "Server" field and leaving "User name" and "Password" fields blank, putting the passphrase in the "Password" field, but it still says "Permission denied" and it doesn't ask for the private key at any point. I also tried ssh-add path/to/privatekey, but it says "Could not open a connection to your authentication agent.", however I'm not sure if ssh-add is even relevant. I can ssh into the server from the terminal just fine with the key/passphrase.

  • How can the maximum number of simultaneous users to log in to Ubuntu server be increased?

    - by nixnotwin
    I use ubuntu server 10.04 on a fairly good machine, with 2.40 duel-core processor and 2GB RAM. My users login with ssh or samba. I have setup LDAP with PAM to sync user accounts between unix and samba. When I allowed about 90 users to login over ssh at once the server refused login for many users. I am using dropbear as ssh server. Even samba logins failed for many users. I need to allow at least 100 users to login at once. Is there anyway to do this?
