I can't select it, though, by hitting X = (where X is the number).</p> <pre><code>/home/nitrodist&gt;ls /h #hits esc + = 1) home/ 2) homeroot/ #hits 2 + = for the 'homeroot' dir 1) home/ 2) homeroot/ #hits just the '=' key. 1) home/ 2) homeroot/ </code></pre> <p>Any ideas? I've <code>su -</code>'d to another user who can actually do it with their PuTTY session and I can't do it there, which makes me think it's a PuTTY configuration issue.

I logged in through a pre-existing SSH connection, but the window froze up and would not let me do anything. Then after a few seconds, it gave me the error message saying that PuTTY had timed out. I tried logging in multiple times, and even to different servers, but sadly, each time yielded the same result.</p> <p>I was able to connect to the network a few weeks ago, but not yesterday. This is a school network and no changes have been made to it recently. I have made no significant changes to my computer recently either. I have no idea what to do beyond the instructions my professor gave me, and that is how I have been trying to do it.</p> 0 PuTTY Network Timeout Error Magpie101 2016-10-30T10:13:49Z 2018-12-02T02:02:35Z <p>I'm using PuTTY on my Windows machine to use SSH on my university server. I run analyses that take up to 3 days to complete. I can connect and start the analyses but eventually get an error message 'PuTTY Network Error: Software caused connection abort'. I have problem solved this - the issue lies with the period of inactivity on PuTTY where it is running the analyses. The network connections ect are all fine. At the moment the only way I can get the analyses to complete is to press enter every couple of hours. This really is annoying as I have to get up during the night! </p> <p>I'm not a computer whizz whatsoever and would really apprentice if anyone could suggest a solution. </p> <p>Thanks :) </p> 0 PuTTY ssh tunnel port forwarding through management server with private key Nikolai 2018-10-30T09:53:39Z 2018-11-30T08:43:35Z <p>I'll try to be as detailed as possible.</p> <p>I try to connect to a server running ActiveMQ and want to forward the port 8161 to port 8162 on my local machine in order to prevent problems when I run a local instance of ActiveMQ on my machine.</p> <p>But to Access the ActiveMQ server I have to first connect to the management server which provides me with access to the network.</p> <p>On both the management and the ActiveMQ server are my public key for authentication on those servers using my private key.</p> <p>I am using Pageant in order to not always having to type in the password for the private key.</p> <p>Path: Local Machine -> Management Server -> ActiveMQ server</p> <p>Since I have to administrate and monitor many other servers this way, I wrote a batch script to access all those server directly with my private key.

On entering the IP address it remains idle for a while and says Fatal Error, Connection Timed Out. I tried disabling my firewall and turning off my anti-virus(K7 total security) but still no use.

I did not yet check whether the default configuration forbids root login. I exited the SSH session and restartet Putty to login as root.</p> <p>The access was denied and after restarting Putty again to login to the account which I usually use, the host seems to have changed its key and Putty warned me about this.</p> <p>Between setting the root password and getting the warning from Putty about the changed host key, less than two minutes passed. Also, I mostly trust the client machine, it is a quite freshly set up Windows 10 machine I got from my employer for work.</p> <p>Should I be concerned, that someone cracked my server in such a short time (I couldn't do it nearly that fast)? It would not make any sense to change the key after already having root access.</p> <p>What would be the best to do now? Should I contanct the data center operator to physically shut down my machine? Or should I just connect via SSH anyway?</p> 1 How do I stop Kitty from doing naughty AutoRelogin after resuming from Windows Sleep? I recall my Putty didn't do this. Where is password cached? htfree 2018-02-17T07:57:39Z 2018-11-27T18:20:40Z <p>I recently switched from Putty to Kitty (on windows7) and now I notice that after Windows Resumes from Standby/Sleep that it Automatically logs me in again. I see in the SSH kitty shell window:</p> <pre><code>Using username "myusername". myusername@myip's password: Send automatic password </code></pre> <p>I have configured KITTY to use files instead of Windows Registry and am using the kitty_portable.exe binary. I have logging enabled but I always have "OMIT known password fields" CHECKED. So I would like to know WHERE is my PASSWORD being CACHED? And how can I disable this feature so that my password is no longer cached? Under Connection->DATA there is nothing set for Auto-login username and when username is not specified its set to PROMPT. Auto-login password is also NOT set. So would appreciate any help to disable password caching.</p> 0 SSH into EC2 instance: Operation timed out Robert 2018-11-26T15:51:42Z 2018-11-26T18:20:15Z <p>I'm trying to ssh into my ec2 instance in order to deploy my MEAN-stack app but no matter what I'm receiving a timeout error.

I'm trying to connect to my server via PuTTy; however, when I entered the ip address of my server and hit enter, it gives the error "network is unreachable". I think that this problem's related to the server being ipv6 because I have never experienced a problem with ipv4 servers I bought from the same site.

Archimedes Trajano 2012-09-20T09:52:30Z 2018-11-20T06:01:00Z <p>I am trying to use Putty to connect to a Linux server that has a file system that contains unicode characters (specifically Japanese)</p> <p>My goal is to make it work the way it worked on Mac OS X Terminal app or the standard Gnome Terminal on Linux Mint.</p> <p>So what I have done successfully so far was connect to the server and get it to display properly when I use "MS Gothic".</p> <p>However, I "lose" my backslash character as MS Gothic maps it as a yen character.

Since I got it a couple weeks ago, I have been having trouble staying connected via SSH. I am able to connect just fine, but it will seemingly randomly disconnect (at different intervals). After being disconnected, I usually have to wait a minute for it to allow me back in. I've used screen to keep my screen session up, and once I get in I can reattach to the screen without issues.</p> <p>I have tested it on three different networks on three different machines, two running Windows 10, and one running CentOS. On Windows I have tried using PuTTY, WinSCP, a Python SSH library called paramiko, and Git Bash for Windows. On CentOS, I just used the CLI ssh command. All with the same results. I have tried SSH-ing into different user accounts, but the issue persists. I have even tried on my phone (Android 6) using ConnectBot. No luck.</p> <p>PuTTY says: "Network error: Software caused connection abort"</p> <p>CentOS CLI says: <code>packet_write_wait: Connection to port 22: Broken pipe</code></p> <p>I've tried setting Keepalives in PuTTY but this has no effect. Once I lose the connection, I am unable to ping the server, even from a different host. I.E. if I am SSH-ing into the server from Machine A, then I get disconnected, then I immediately go to Machine B and try to ping the server, I get no response. That seems to me like it's the server's fault. On the other hand, if I manually disconnect (cleanly), I <strong>can</strong> ping it.</p> <p>The Virpus support team says my SSH settings are fine and that they were able to keep a connection (on a Linux box) for at least an hour without problem, after which they manually disconnected. In other words, they can't replicate the problem.</p> <p>In an attempt to solve the issue, they changed the public IP of the server, but this didn't fix it. Their next step was to redeploy to another node, which seemed to work for a little bit, but now I'm still having the same issue. They told me all they could do now was to redeploy to another node. Since, they've already done this, I'm thinking that won't fix it.</p> <p>Does anyone have an suggestions?

PuTTY will partially display the output, hang for awhile, before showing the error.</p> <p>The second way is to open up vi/vim/nano on a 9kb config file with 263 lines and hold the pageDownKey/RightArrowKey for some seconds. In this case, PuTTY also hangs before showing the error.</p> <hr> <p>However, the disconnect can be avoided when i use <code>less</code> instead of <code>cat</code>. Similarly, it can also be avoided by pressing the pageDownKey/RightArrowKey slowly, one key at a time.</p> <p>My guess is that there could be a problem in the bufferring, transmission or display, where a larger amount of input/output than usual being send/received in small bursts might be causing the software error.</p> <p>Does anybody face the similar issue?</p> <p>Are there any configurations or workarounds that can potentially solve this issue?</p> <hr> <p>Update 1:</p> <p>I used the windows built in ssh client to no avail.</p> <p>Openssh-server 1:6.7pl-5 on an OMV3 image (debian jessie) doesn't have this issue.

I again use Putty to connect to the internal Ubuntu server using the socks proxy above.</p> <p>Now I want to get the server GUI using VNC, but I am unable to connect with the socks proxy. I tried forwarding the ports, but since I am newbie to this, I may have done it incorrectly. So how can I run VNC from my Windows machine to access the remote VNC server?</p> <p><a href="" rel="nofollow noreferrer">This article</a> did not help me to connect using <code>vncserver</code>. RDP isn't working, either. The VNC session is on a different server accessible only from <em></em> as a socks proxy.</p> <p>Note: I am able to SSH to the internal servers using the configuration above with the <em></em> as socks proxy in Putty.</p> 4 How to name openssh public and private key pairs? I-GaLaXy-I 2017-09-06T15:25:38Z 2018-11-12T16:01:39Z <p>I am using public/private key pairs for a long time now. And nearly the same time I'm asking myself over and over again, which file extension I should use. It seems to be that at least for the public and the private(openssh) keys is no convention at all?</p> <p>I mean in PuTTy there is a special extension <code>.ppk</code> for "PuTTy Private Key" and the public key is stored either without an extension, or with <code>.pub</code>. I personally prefere not to use <code>.pub</code>, because Microsoft is using this extension already for MS Publisher. So for PuTTy I store both keys with the same name and add <code>.ppk</code> to the private and nothing to the public key. And for that case I can live with that. I can identify which key is the public and which the private one and that the private one is for PuTTy only.</p> <p>But what should I do with the private openssh key? Just store it without an extension? Or use something like <code>.openssh</code>? Also if there is no convention really, if someone just thought about that and sorted out some sort of concept for himself, I would also appreciate that...</p> <p>Thanks in advance!</p> 1 CentOS 7 Minimal Installation on Hyper-V: X11 forwarding using Xming and PuTTy error, xhost: unable to open display ":0.0" Mario Echeverría 2016-01-23T16:00:42Z 2018-11-12T12:23:10Z <p>Before telling me that there are a lot of post relates to X11 forwarding error, let me put you in context of the things that I have done:</p> <p>I have installed the following packages:</p> <pre><code>yum install -y xorg-x11-app* yum install -y xorg-x11-server-utils yum groupinstall -y 'X Window System' yum install -y xorg-x11-xauth xorg-x11-fonts-* xorg-x11-utils xterm yum -y groupinstall fonts </code></pre> <p>Also I uncommented the following setting in<code>/etc/ssh/ssh_config</code></p> <pre><code>X11Forwarding yes </code></pre> <p>On my Windows 8 PC, I ran Xming. Then I checked "Enable X11 forwarding" on PuTTy, and set the X display location to ":0.0". Then I opened PuTTy again and connected to my virtual machine. Then I ran the following:</p> <pre><code>xhost + export DISPLAY=:0.0 xclock </code></pre> <p>This is the resulting error:</p> <pre><code>Error: Can't open display: :0.0 </code></pre> <p>Does somebody have an idea what I am doing wrong or what else do I need to fix that problem? Let me tell you that I have done this before but only for CentOS 7 Desktop Installation and it wasn't hosted on a Hyper-V VM.</p> <p>Thanks in advance.</p> 0 Putty not connecting via command line - Network error: connection timeout [duplicate] Rogério Dec 2018-11-12T12:15:45Z 2018-11-12T12:15:45Z <div class="question-status question-originals-of-duplicate"> <p>This question already has an answer here:</p> <ul> <li> <a href="/questions/1298580/putty-shortcut-using-target-how-to-specify-port" dir="ltr">PuTTY shortcut using target: How to specify port?</a> <span class="question-originals-answer-count"> 1 answer </span> </li> </ul> </div> <p>I can usually connect my server via SSH using the Putty.exe interface:</p> <p><a href="" rel="nofollow noreferrer"><img src="" alt="enter image description here"></a> <a href="" rel="nofollow noreferrer"><img src="" alt="enter image description here"></a></p> <p>But when trying the same via command line:</p> <pre><code>"C:\Program Files\PuTTY\putty.exe" -ssh </code></pre> <p>I get this error: </p> <p><a href="" rel="nofollow noreferrer"><img src="" alt="enter image description here"></a></p> <p>What's wrong?</p>  Microsoft office activator |  windows activation crack |  windows product key |  windows 10 product key |  windows 7 ultimate product key |  windows 7 keygen |  activate office 2010 |  office Project keys |  project professional product key |  office 365 office 2016 office 2013 key |  office 2016 office 2013 key |  windows 7 professional product key |  windows 8 professional product key |  windows 10 professional product key |  office 2016 professional product key |
