Slow ping and ssh from ubuntu; fast from windows
- date: April 17, 2012
I have googled the issue and most suggest that this is a problem with ping's reverse DNS lookup and an -n option will solve this. However, ping is not the only problem but ssh as well.
To illustrate, I have 2 clients on the same network: let's call them UBU(10.0.0.106) and WIN(10.0.0.103) -- Ubuntu 11 and Windows 7 respectively. The following settings are the same for both machines:
DNS: 10.0.0.1, 10.0.0.50
Pinging a FQDN from WIN is fast as expected but from UBU, it is verrry slow. This can be sped-up by disabling reverse DNS lookup of ping:
~ $ ping -n example.com -c 4
64 bytes from x.x.x.x: icmp_req=1 ttl=49 time=210 ms
64 bytes from x.x.x.x: icmp_req=2 ttl=49 time=206 ms
64 bytes from x.x.x.x: icmp_req=3 ttl=49 time=208 ms
64 bytes from x.x.x.x: icmp_req=4 ttl=49 time=220 ms
An ssh connection from WIN to the same FQDN is also fast, but from UBU, it is painfully slow (the server responds after about 10-60 seconds). I also already turned reverse
ssh for that pesky windows installation of yours

At work I have to use windows for this and that reason and the other day I started to think about the fact that I don't have the command 'ssh' there.
Sure, I have putty and with it the cmd-compatible plink, but they don't respond when I call for 'ssh'.
As it turns out it is fairly simple to fix this little annoyance, and by doing so, calling home to your beloved ubuntu machine will feel a little bit more natural.
Firstly, there are aliases in windows. You'll have to fiddle about a little bit in the registry, but if you add the key:
And set the default string to your path to putty:
You'll be able to put 'ssh' into the run-dialog and have it start putty. Putty will also take an address as an argument, so putting 'ssh host' into the run dialog will work as expected! =D
That takes care of the gui, but what if you're in cmd and wa

How can I attach to the server from Windows?
I've disabled ftp to all but the web-server so I think I need SSH. My Ubuntu laptop is working fine with SSH, even in Nautilus.
On Windows however, PuTTY is a strain on the eyes and Filezilla doesn't seem to allow a file move on the server without brining it local first.
Anyone know of a better way to attach the worlds most powerful operating system to little old Ubuntu? Ideally a transparent SSH plugin for explorer that would allow my wife to also attach her work machine for backing-up to the server.
unable to ssh from windows with public/private keys
location: ubuntuforums.com - date: March 26, 2011
i'm using ubuntu server 10.10 and i have an ssh connection active on port 22. i connect from my laptop client with username and password, which is insecure. i've been using ubuntu server for about 3 years now, but i was unable (like ever) to create a private/public key connection to my server.
i followed so many tutorials, i don't remember. none of them are working. the last ones were: http://www.wowtutorial.org/tutorial/22.html and http://linux-sxs.org/networking/openssh.putty.html
every time i'm trying to connect to ssh with putty, it says: 'putty server refused our key'.
today i've tried http://linux-sxs.org/networking/openssh.putty.html made the following steps:
- generated keys with sudo ssh-keygen -t rsa and saved them to my ~/.ssh/ directory
- copied id_rsa.pub like this: sudo cp id_rsa.pub authorized_keys
- edited sshd_config: sudo nano /etc/ssh/sshd_config
- the config is:

I am using Bitvise Tunnelier on the Windows Vista box. Can someone step me through exporting the keypair from my Maverick desktop for import into Tunnelier? I tried:
ssh-keygen -e -f id_rsa
But it looks like that only exported the public key. Don't I need the pvt key also? How do I do that?

HOWTO: Tunnel VNC through SSH from a windows machine
location: ubuntuforums.com - date: January 19, 2005
VNC is a utility that allows you to remotely control your PC from another networked PC. VNC has been around a long time and works well enough on high bandwidth connections however by default it passes everything in the clear and is not secure. This HOW TO walks you through tunneling VNC through SSH to secure the traffic.
NOTE If you need to use your machine remotely FreeNX is MUCH better than VNC, however if you need access to your already logged in session VNC works well enough. If you need help jdong has a great HOW TO for FreeNX located here: http://www.ubuntuforums.org/showthread.php?t=1968
On your Ubuntu desktop click computer->Desktop Preferences->Remote Desktop to bring up the VNC properties.
check the following boxes:
Allow other users to view your desktop
Allow other users to control your desktop
Require the user to enter this password *Enter your connec
