I am using D'link rouer DSL-2750U. I have installed raspbian jessie in Rpi 3 and connected it to router. Connected my laptop to router wifi. But when i try to connect putty using the IP address of raspberrypi which i have got from router admin panel it gives connection time out error. Also i have tried to adjust keepalive seconds in putty connection setting and enabled X11 forwarding.
I recommend you to check if ssh is enabled in your device:
sudo raspi-config
then navigate to ssh, hit Enter and select Enable or disable ssh server. Now reboot raspberry and try again.
Please Open you RaspberryPI terminal and run the command "sudo service ssh restart". Try connect again from putty
For everyone who is getting a network error from Putty even all of their network settings are okay, you just follow a single step:
Just go there in Connection and set the time for 10 sec or more.

I was able to get the Pi to boot up and connected to WiFi. I am able to ping it from my laptop, but not able to SSH into it as root. I keep getting the ssh: connect to host <raspberry-pi-ip-addr> port 22: Connection refused error.
Scanning with Nmap shows no ports are open.
How do I get the SSH server to run?
Or at least enable logs and write to SDCARD such that I can look at what is going wrong.
I've purchased a RaspberryPi 3 B+, booted a NOOBS Raspbian and I've been trying to open a ssh connection via an Ethernet connection for the last couple of days. My goal is to be able to access the Pi via ssh while also sharing my Wifi connection to the Pi. My machine is running Ubuntu 18.04.01.
So far I've tried creating a new Profile for the Ethernet connection but without success. The only way the connection can be "successfully" created is by checking the "Link-Local Only" box, which will add "169.254.154.221" to my IP addresses. However, the Pi can't be found on the local network (pinging raspberrypi.local fails and an nmap scan doesn't return any good results).
Also, when I was first trying to connect the Pi, I was able to see it by executing "arp -a" in terminal, but now it is gone.
I've also tried connecting the Pi to my friend's Macbook and the Pi gets a local IP address, but it is still not possible to share the laptop's internet access to the Pi.
Even with the ssh enabled, I cannot connect my Windows 10 machine to the pi. When I try to login with PuTTY, it says "Access Denied". Any ways to fix this?
I'm use Linux server with vsftpd connection created successfully but i can't retrieve the files
Your screenshot shows that the connection timed out when trying to transfer something (LIST) after switching to Passive Mode (PASV). In my opinion, probably your firewall is not correctly configured for Passive Mode and therefore is blocking the connection.
Try allowing incoming (inbound) connections on port 40000 to 50000 for all IP address or the IP address of your FTP client. Configuring firewall is firewall-specific, therefore, I cannot give you detailed instruction on how to do this.
sudo ufw allow 40000:50000/tcp
sudo service vsftpd restart
I had setup FreeRADIUS V3 on a virtual-box that runs Ubuntu 16.04 with the using of MySQL as a database.
Also, another virtual-box running Mikrotik RouterOS to simulate a connection between the PC and router. I have configured Mikrotik as a hotspot with FreeRADIUS through the Ubuntu virtual OS.
It was running like a charm.
Now I got a physical Mikrotik router and have connected it to the ISP router's Ethernet port to replicate the connection I created previously, but when connecting to the Mikrotik router through WiFi, and after entering username and password, I get the following error message:
Radius server not responding
I opened the debug mode in radius freeradius -X, and I found radius got the Mikrotik request and replied "Access-Accept"
I had to catch my problem using the secret key which I set it up in clients.conf.
The NAS (Network Access Server) table in database is not trusted as somehow FreeRadius stops reading from it. There is some option in SQL module that makes radius read it while starting FreeRadius. Therefore, I could not use it while I am using FreeRadius. I had to restart FreeRadius to get the modified/new records.
