Recently, Putty keeps intermittently freezing and locking me out of the system (i.e. I can't stop the session and I can't re-login via ssh again until I've gone to the machine and pressed "reset").
So far, it mostly occurs when opening a file in VIM, but it does sometimes occur when using tab to auto-fill a file or directory name at the command prompt.
i have an asus eeepc that i recently upgraded from ubuntu 9.10 to 10.04. the wireless networking has worked great up until about 2 weeks ago. now it occasionally drops the connection (can't ping the gateway), even though the "blue bars" still say connected. my current solution is to click the bars, do a "disconnect", and then reconnect.i've ruled out the router being a problem (all 17 other wireless devices in my house remain connected), and i've ruled out a laptop hardware problem (when i dual boot into win7, i never lose my connection).
i'm new to linux (installed 9.10 back in february), but not new to computers/networking. i run a major campus lan [windows based] and have worked all aspects from the early mainframe days to client support to server admin to helpdesk - after 17 years, i'm now in management, so i've lost my edge a little... plus, being brand new to linux, i'm feeling a little lost in the troubleshooting aspect of this.i do believe that i've narrowed my problem down to "almost exactly" when this occurs. the wireless connection drops out as soon as i start to do "network intensive" stuff like watch a videos video, play a facebook flash game, or (and here's the kicker), try to run the update manager. unfortunately, this means that i have not been able to update for a few weeks now. i'm up to about 150mb worth of updates that are waiting.
Our home broadband (TWC/RoadRunner/San Diego) intermittently drops out for minutes at a time. In WinXP, I had a logger that would ping one or more sites (e.g. Yahoo.com), log the ping times, and display the data in an interactive graph. This was very useful in showing the ISP tech (I didn't know about Shibboleet then).The problem is still unsolved after two visits, but now I'm using Ubuntu 10.04. I'm looking for a similar tool. I'm a Linux newb (i.e. "just write a script" isn't helpful at this point), so I'm hoping for something user-friendly with a GUI.Can anyone recommend a Linux utility that...Logs ping timesDisplays results graphicallyDoesn't require advanced Linux skills to set up

View 1 Replies View RelatedOn my Acer laptop, I have Ubuntu 8.04.4 LTS and a static version of the Skype Beta 2.1, specifically version 2.1.0.81. I recently made the upgrade to it from an earlier version because I needed to have the screensharing feature to work. Previously Screensharing from others was showing up in a tiny window I couldn't resize. But the Skype Beta 2.1 works fine regarding screensharing.
But the problem I'm having now is that the sound intermittently goes away, but only for Skype. It seems to go away if I walk away from my laptop for a long time. When this occurs, I cannot hear or record sound through Skype, but it works fine through other applications. If I shut Skype back down once it is in this failed state, and come back in, then it remains in this failed state. The only resolution is a reboot, and then it's fine again.
The only thing I can think might be the issue is the Gnome Power Manager, perhaps? I mean, my fan on my laptop spins down if I walk away for a long time, so I know some kind of laptop power management is engaging.
I tried following this guide:

And it suggested removing PulseAudio and using esound instead. Well, I tried that and rebooted, and my desktop wouldn't boot properly. So, I did CTRL+ALT+F2, logged in, and then did "sudo apt-get update; sudo apt-get install ubuntu-desktop". All was well again, but unfortunately it brought back PulseAudio again.
I have 2 computer: 1 computer install ubuntu v9.10, in this computer already installed openssh-server and openssh-client, and 1 computer install windows. In computer with windows , i used putty connect to computer with ubuntu, but i can't connect. I don't understand what's error.
In the Putty , i configured:

This is error: "Network Error: Software caused connection abort"
In computer with windows, i can ping computer with ubuntu and in computer with ubuntu i can ping computer with windows.

View 7 Replies View RelatedThis app embeds putty and allows you to save ssh and telnet connections (including post login commands). You can also save the connections and sort them however you like. It's great for organizing linux clustered servers etc... Tabs are also a plus (yes I know konsole does this part as well)So to the point at last. I finally upgraded to OpenSuSe 11.2 and I was looking for an app that does much the same thing.
View 2 Replies View RelatedI got a new low power file server (Atom 330 with ion), but didn't enjoy it since.
I installed Ubuntu server 9.10 64bit.
I randomly experience connection drops. As I'm installing and testing, there are lots of ssh windows open, I transfer much data using scp from my laptop to the server (all connected to wired lan).
Connection drops are as follows: ssh windows terminate with "connection reset by peer", but not always all the ssh windows terminate. For example, I edited a mediatomb config using nano, that stayed open even with scp and all other ssh windows cut.
I also have apache2 installed because I'm running urd (a usenet download tool). It seems that when I start the deamon, connection drops. So I killed apache2 to try out but that didn't solve the problem.
I left ping run all the time, and the server is pinging back all the time, which is really strange as I thought that a connection drop means the whole network interface going down.
When this drop occurs, I have to wait 2 minutes until I can ssh back into the server.
I also installed mediatomb, but it isn't really fun to stream a video to my ps3 as it always hangs after 5 to 10 minutes.

I've had a computer running Ubuntu connected to my TV for a few weeks now, but as of yesterday, I can't get it to keep a connection to the Internet. Everything works well for an hour or so after a reboot, but then no WAN connections work. When this happens, no sites load in Firefox or Chrome, I can't ping Google, I can't SSH to the box from work, and none of the pages I have running on apache load from remote computers. However, all local area connections seem to work fine. SSH from within my LAN takes much longer than usual, but it does still connect.

when I try to connect via PuTTY from a windows machine I get " PuTTY Fatal error connection timed out. I try to do so via a router redirecting IPadr:86 to local adr:22 on the Linux machine.
I seems not to be a routing issue since the router is setup to redirect apparently correctly.
Well I have stopped iptables and selinux is disabled. The sshd deamon is running. I can logon with ssh locally "ssh webcamATlocal adr".
I am trying to play my audio files at work from my home computer over ssh. The computer I use at work is windows and so I use Putty to make that connection. However when I mplayer file.mp3, the file starts to play, but I am assuming it's playing on my home computer.....so, I am wondering, how do I forward the audio to my remote computer?
and no, can't use a CD... I work in a car with no CD player, and the computer is a Panasonic Toughbook with no CD-ROM... options are limited.
Hello, I've installed OpenSwan with xl2tpd on my server, and set it up for roadwarriors connecting using certificates.
My server is Debian 5.0.8, I am running xl2tpd 1.2.0, and Openswan IPsec 2.4.12, my clients are all Windows, and I am testing my setup on a Windows 7 client.
I have no problem connecting to the server, but after some time the connection drops. I removed the idle option from the ppp config but it does not make any difference.
Even when I create constant traffic with ping -t the connection drops also.
I have no problems reconnecting right away.
I have been hacking at this for a couple of days, reading every post I can find, but I have not found a solution to my problem.
Here are my configs and logs:

I had Ubuntu guest installed on VMWare. The Host OS is Windows 7. But now I want to migrate it to Virtual Box. I migrated it, but it does not allow PUTTY to connect it. It says "connection refused". On VMWare on same host and same guest, PUTTY connection is successful. But it does not allow on Virtual Box. It says connection refused. Both on VMWare and Virtual Box, the guest Ubuntu is configured using NAT networking.

I'm having problems with my mobile connection. This has been working fine for months, but in the past few days it has connected OK, I've been able to transfer data, but after 30s the connection closes. Setup is Acer AA1 with F12 connecting via bluetooth to Nokia 3110c on O2.
So to try and figure out what's happening I put the bluetooth dongle in my desktop PC, also running F12, made a connection and again it dropped out after 30s. Then I fired up windows on the AA1 and made a connection using the same dongle, this time it held up OK. This leads me to think that something has changed recently in F12 to upset it.
Can you find my blind spot? I had PuTTY up & running untill I did a reinstall of Fedora13.I can ping 192.168.1.163 fine. SELinux is disabled. Firewall is default (SSH allowed on p22).I have just disabled the firewall with same result)

In order to get my shares working I first have to connect to the windows shares from the Ubuntu machine. Then I can connect to the Samba shares from the windows machine. If I don't continue to use the shares. It'll drop the connection and I have to unmount the windows shares and start the process over. The wireless network still shows as being connected but I get an error on the windows machine if I try to connect. I've Googled this and it appears to be a Windows problem. I know this is a ubuntu forum but thought I'd ask for any info. I believe that this is also what is giving me shared printer issues as well.
View 2 Replies View RelatedI'm having a really strange problem with my wifi connection on my laptop. The ethernet connection works fine and so does the wifi connection - as long as I sit within one meters range from my router! As soon as I take the laptop further away the connection drops. The router is still being found by network-manager and the signal is just below 100%, but when I try to establish a connection it fails.
I'm sitting here on a fresh Ubuntu 10.04 install, and I had exactly the same problem with 9.10. That time I went through a lot of different procedures, and in some strange way the problem was solved. I haven't been that lucky this time though, I've tried reinstalling network-manager, using ndiswrapper, installing the wireless backports package, tried all kinds of drivers.. nothing works.
There shouldn't be any problem with the connection itself; I've had a perfect connection downstairs but now I can't even connect if I stand two metres from the router! Has anyone experienced anything like this and managed to fix it? My wireless card is Atheros AR2413. This is an example from daemon.log

I have an Acer Aspire One ZG5. 160GB HD, 1GB RAM model. I've done a fresh install and an upgrade of 10.04 and have the same problem both ways. I am able to connect to my wireless connection but it is dropped after about 5 minutes and have to wait about the same time to reconnect. I've had to roll back to 9.10 being that I use the netbook for work and school on a daily basis.
View 1 Replies View RelatedI have had this issue for a while on my centos 5.4 dedicated server with 1and1. If I reboot my system, my connection starts and then drops in about 10 seconds after the system has booted.I connected through the serial console and noticed there was only one thing that seemed suspicious while booting. named could not start for some reason. So my question is - are these 2 problems related? If not, what could be the reason for my connection to drop?At the moment the only way of getting the connection back up is by running dhclient. This works until the next reboot.
View 1 Replies View RelatedI could not find a solution to this problem anywhere. I use a ubuntu server to play (stream) mp3s and movies to other computers on my network. It works most of the time, but sometimes in the middle of a movie or a song it will drop/hiccup--saying it is "not reachable". I am not overtasking the server at all, and merely playing an mp3 that takes up less than 10% of the bandwidth, yet it drops it for a split second.
I have a WRT160N router (DD-WRT of course) with 4 clients connected (2 of which are wired). The ubuntu server is connected via ethernet and all machines have the same issue. It can't be the router because another Windows machine works just fine for streaming these files. I just can't understand how it can lose connection for a second or so. It may just be the file-system or some service that is hiccuping, but I have no idea...

View 9 Replies View RelatedI have a server running Ubuntu 10.04. I use it for mysql as well as samba file sharing across 10 computers. It had been working out great. I only ever needed to restart after I would install updates and to sort of thing. Starting this week however, it has started kicking all the computers off of both mysql and the samba shares every few minutes. It is very strange. The mysql connection can be restored just by closing the database and reopening it. The file shares are only a problem if you try to access them though a program other than your file browser (e.g. save a file you are working on in word to the server). The server never shuts down and all services can be reconnected immediately. It is very strange. I do believe that the server installed some automatic updates at the beginning of this week when this all started happening. I am not sure if one of the updates is causing the server to do this or not.
View 1 Replies View RelatedHaving struggled to get the wireless connection at least working I find it drops out after 15 minutes or so. When I check for wireless connections I can see none at all and the "Disable/Enable wireless conncection" has disappeared, the Network one is still there. I get an auto reconnection if I reboot and all is well for another 15 minutes. Is there any way i can recover the situation without a reboot? I am trying to install the hplip-3.11.5 driver for my new wireless printer,the program take a while to install and by the time it has started looking for the printer the connection has dropped out. I can't be sure but I don't think it was dropping out before I connected the printer using my wired pc. All good fun but I'd like to get it sorted so I can get the engine back in my motorbike, the sort of technology I prefer!
