I've a question about SSH reverse tuel. I've an ubuntu server with sshd installed. I open ssh reverse tuel from a remote machines, on that machine the coection is restarted every time the tuel is interrupted. Whenever a tuel is opened, on the SSH server i can see two coection using netstat. One listening to the interal server port. Then other on an exteal port. The latter one is the SSH tuel. As example. given 138.10.20.10: my ssh server and 10.34.23.12 my remote pc, 5000 the port on my remote pc i would like to access to ssh -R 1122:localhost:5000 [email protected] Now server side i've two listening coections, which looks like this tcp6 0 :::1122 :::* ...

I know that this is a common problem with a known solution. A quick web search tus up many results that point you toward the ServerAliveInterval (or less commonly the server-side ClientAliveInterval) configuration options. Setting one of these to some arbitrary value such as 15, 60, or 120 will solve the broken pipe issue. My question is why? Why does this happen in the first place? Who is closing the socket? I have my doubts about the OS killing the coection due to inactivity, given the fact that the TCPKeepAlive option is enabled by default, which causes TCP keepalive messages to be sent in order to detect clients dropping offline. So the OS won't see the coection as inactive anyway. In th...

Right now I'm ruing a java app by SSH-ing to a VM on Google Cloud Compute. I issue a command to run the app and it loads a console. As soon as I terminate the SSH coection, the app shuts down. I assume this is because the console has been closed. I would like this app (which is a server) to persist after I terminate SSH, and, at any point, I would like to be able to recoect to the console and issue commands on the server. Thank You!

I've tried to use them with combinations of command control and alt, but nothing seems to work. It would be a total hit on my productivity that I can't delete or use navigation in ssh...I didn't notice this problem before so I suspect something changed it and made this now not work. I'm using openssh on the windows box but cygwin is also installed too. Let's block ads! بخوانید...

I have a server that I ssh into all the time. I have ssh keys set up, but I'm noticing a strange behavior with video files that I'm trying to edit with VLC. As most know, with a program like Thunar, you can open individual files with VLC by double clicking in Thunar and you can also drag a selection of files onto a ruing instance of VLC to add them to a playlist on the fly. This works as expected with local files on the localhost. However, when browsing the remote server with Thunar, I'm able to open individual files with VLC by double clicking a single file, no problem...But, when I try to drag and drop a bunch of files into a ruing instance of VLC, I get a prompt that reads: Please enter ...

I'm ruing ConEmu on Windows, and would like to have task that opened a new console tab and run vagrant ssh automatically. Right now, I have this, which works, but produces a lot of output: "%ConEmuDir%..Gitgit-cmd.exe" --no-cd --command=usr/bin/bash.exe -l -i -new_console:s30Ht:'tests' -exec "vagrant ssh". The output looks like this: Here it seems to print a lot of the commands it does, before ruing vagrant ssh, and then logging in on the vagrant machine. Is there a way to get rid of all the output? My default console is the Git bash. Let's block ads! بخوانید...

I have a two months old: Seagate Desktop SSHD - 2TB Im ruing this SSHD as a secondary drive (have an SSD ruing as boot), being a "backup" drive. I've created two partitions with it: one with 1.5TB one with 300GB'ish Suddently whenever requesting anything from that drive, the response time is VERY slow. At a point it was slow and next day alright again, however the last 4-5 days it has been consistantly slow. I experience the following: When clicking through folders and (usually) reaching some 2-3 ier folder index, the SSDH stops up and VERY slowly loads (with progress bar) before the folder renders Writing to a file (like .txt, .php, .js /whatever) *saving work - takes 3-4 secs everytime ...

I have added Host Only Network as the second network interface on VirtualBox 5.0.24 on Mac. Here are the relevant vb networks vboxnet0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500 ether 0a:00:27:00:00:00 inet 192.168.7.1 netmask 0xffffff00 broadcast 192.168.7.255 vboxnet1: flags=8842<BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 ether 0a:00:27:00:00:01 vboxnet2: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 ether 0a:00:27:00:00:02 inet 192.168.59.3 netmask 0xffffff00 broadcast 192.168.59.255 But none of those addresses are recognized on the guest itself (can not ping).

I'm very confused. Every manual I read the last 15 minutes tells me this should work but it does not: $ ssh-agent -s SSH_AUTH_SOCK=/tmp/ssh-syXn9Tk09V9P/agent.16332; export SSH_AUTH_SOCK; SSH_AGENT_PID=16333; export SSH_AGENT_PID; echo Agent pid 16333; $ eval `ssh-agent -s` Agent pid 16362 $ ssh-add -l The agent has no identities. $ ssh-add .ssh/[email protected] Enter passphrase for .ssh/[email protected]: Identity added: .ssh/[email protected] (.ssh/[email protected]) $ ssh [email protected] Enter passphrase for key '/home/iras/.ssh/[email protected]': In the ssh config there is an entry for server.de with another identity.

known_hosts file looks not trivial. On Windows I see it contains hostname, ip address and some RSA key. On linux I see it contains several keys separated by bar. Who manages this file on Windows? How to add some host as "known" to this file on Windows? Can Putty do this? If Putty has some host as known, can I copy this host record from Putty database to ~/.ssh/known_hosts on Windows?

As you seem to understand, shell built-in functions such as echo are processed by the ruing shell and therefore do not require a new process to be started in the foreground (normally). However, if you send them to the background, they need to be controlled by a distinct shell and will consequently start a new shell process with the command in question. This should be fairly easy to observe in bash as sending a process in the background will show the new process id next to the job number such as: $ echo 'hi' & [1] 19536 hi In this case, process 19536 is a new bash instance.

An exteal command was have new pid on executed as background process using & character, But The inteal command was not done as separated process on normal execution because it done with shell. but what happen if the builtin process was executed to back ground, like, echo test& or echo cd& thank you, Let's block ads! بخوانید...

So I got used to a lot of things which are changed now, and I want to know why they are changes. The main problems are: When I exited vim it's contents would disappear, now they are still on the screen, and are pushed up as with normal lines. When using the mouse's scroll wheel, I could scroll up to see past commands. Now it goes through past commands like the arrow keys. Let's block ads! بخوانید...

I would like to login to a remote server by executing sth. like ssh remoteServer. The remote server can only be reached via a login server (which there are two of). There are two routes I would like to be able to take (in case one login server caot be used): A → B → D A → C → D Some info: A: my local computer B: login server; only allows useameB/password login (no key file); I caot make changes (save key file etc.) C: login server; allows key file login; I can make some changes (not a superuser though) D: target server; can only be reached from B or C; allows key file login I'm using a password protected private key file (on A and C; the same one) which I can use to log in to C and D.

I have 3 servers (Ruby, Sapphire, Onyx) that I have been trying to setup passwordless (host based) authentication between for all users. I've configured the machines to use host based authentication and have modified the ssh_config, sshd_config, shosts.equiv, and ssh_known_hosts per this guide. I'm encountering this error however when I attempt to coect from one of the machines (Ruby) to one of the others (Sapphire): get_socket_address: getnameinfo 8 failed: Name or service not known get_socket_address: getnameinfo 8 failed: Name or service not known Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password,hostbased).
