I am working on a project and for that project I need a software which is on my university server. Before I was working in my laboratory. Due to some personal reason I had to leave the country. Before leaving I setup SSH and VNC on my host computer which is a linux machine with Centos distribution. After I left the country I used to access my host computer from my home country using putty and VNC viewer. Yesterday when I tried to SSH onto my host I got this Error: " Software caused connection abort". I asked the system administrator in my university and he told me that SSH is blocked for outside the country. The only solution for you is to be inside the university network first and then access the host using putty and VNC.
Can someone please walk me through how can I do this.
You will probably need to use a VPN that is located within the same country. That way the university servers think you are logging in from within the country.
For example, I am in Brazil, but when I use my US VPN most websites see me as coming from the US.
Hi I think you need to find a host in your university country and connect to that host first. Then login in to your university laboratory via that host.

I am trying to learn how to use SSH and it's kinda hard for me. I installed PuTTY (windows 7 32-bit). It asked for my IP so I searched 'What is my ip' and pasted it in. Then in the 'command prompt style box' I entered my username 'dell'. Now it's asking for password. I'm really confused because my laptop has no password and there's no password I know of. Can you guys help?
Entering nothing doesn't work:
Putty is just a command line interface, that will allow you to run commands like ssh.
However, if you want to SSH into your machine you have to install an SSH server on your machine.
There are multiple solution on the web:
https://www.howtogeek.com/howto/41560/how-to-get-ssh-command-line-access-to-windows-7-using-cygwin/
122.162.179.255 is likely the IP address of your network router / ADSL modem / etc and not your Windows PC (which won't have an SSH server installed by default).
There really is very little to learn about SSH itself, at least for basic day to day use.
If you want to learn how to use a UNIX-style command prompt then consider installing WSL or setting up a Linux installation on a separate computer (maybe a Raspberry Pi).

so I wanna be able to access my files on my Ubuntu 18.04 LTS machine from my other windows machine by typing its local IP address like this image
but I don't know how to setup apache to display the folders I want, all I'm getting when I type my IP address in the other machine is the apache Ubuntu default page, so how can I make this.
thanks in advance.
To access file system on remote server you can use SFTP to transfer file between systems.
Download Winscp : https://winscp.net/eng/download.php
Type your local ip address including username and password into setup then you can access your remote folders.

I made a server for a research project two days ago (Ubuntu 14.04 LTS, Apache2, PHP). I haven't set a domain name yet, so the webpage is only accessible via ip adress (in this case ipv6,inet 6addr at ppp0).
I asked a friend to try it, everything worked fine on her computer and mobile phone too. Later I asked some friends and colleagues to access the webpage but they were not able to do so. They got the 443 unreachable error message. My first friend was still able to access the webpage her computer and mobile phone. I run through some questions here and on other sites to solve this problem but nothing helped.
I asked the users to check their IP-s on https://www.whatismyip.com/. When using her ethernet and wifi at home, my first friend had ipv6 type IP address, she was able to access the site. The other users had ipv4 type address and they were not able to access my webpage. I asked my first friend to switch to the mobile internet provided by her telephone company. After this she wasn't able to access the site and she had ipv4 type IP address. After she switched back to her wifi she was able to access the page again.
What could be the cause of this strange problem? What can I do to solve it?
If the server has only IPv6 and the user has only IPv4 then they won't be able to communicate. More and more clients have both IPv4 and IPv6 these days, but unfortunately there are also many clients left that only have IPv4.
If you want your server to be reachable by them then you'll need to make it reachable over IPv4 as well as IPv6. There are free services that help you do that (cloudflare comes to mind)

Hi I just finished setting up my new apache web server from my laptop running windows 7. I created the server using apache, then port forwarded my laptops ip (port 80), and finally got myself a free domain using dot.tk. Ive added a few files and done some basic html stuff, and it is successfully up running and accessible to everyone through the domain. But i have a question. Lets say someone was to download files from the site. Is my local network's bandwidth consumed? If anyone can explain how this works that would be great.
Thanks in advance.
The data will run through all segments connecting the client (your end user) to the host (your hosted web server).
So if they need to get to your house where your laptop is to get to the web server, then your house's network connection's bandwidth will be used.
If you hosted it remotely on some shared server site like Amazon instead, then the bandwidth of remote clients accessing your server never uses your home connection's resources, it only uses the resources between their computer and Amazon.

I'm trying to set up an sftp on a networked server. I can access the machine through the outside world by first ssh'ing into a network login server through the following process:
ssh [network-username]#login.server.co.uk
then, once logged in
ssh [server-username]#[hostname]
Is there anyway to sftp into the networked server? I cant find a way to add the initial step into the login process.
Thanks!
You have not specified what SFTP client you are using.
In general, some SFTP clients DO allow SSH tunneling.
WinSCP for instance.
See Connect to FTP/SFTP server which can be accessed via another server only.
OpenSSH suite allows that too.
For example see Forward SSH traffic through a middle machine.
