How to proxy SpringBoot application via Apache HTTPD

First we need to add the following to virtual host definition.
ProxyPass / http://127.0.0.1:8080/
ProxyPassReverse / http://127.0.0.1:8080/

Enable the following modules:
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so

Run SpringBoot application. Note that it starts on 127.0.0.1 interface. Also note that we pass extra parameter allowing for non-blocking entropy source.
/opt/jdk1.8.0_101/bin/java -Dserver.address=127.0.0.1 -Djava.security.egd=file:/dev/./urandom -jar spring-boot-app.jar &

Restart webserver
systemctl restart httpd

That's all folks!

Hardening OpenWRT - adding non-root user account

I have at home an OpenWRT on TP-Link 1043ND. As I'm most of the time out of my home, I use this for two functions:  - as reliable WiFi Access Point  - as last resort remote access device  - as a box used to wake up other Ethernet enabled devices @ home. As this box is exposed to Internet via IPv6 address, I decided to harden it a little. 1. Adding extra non privileged user account: root@OpenWrt:~# opkg update root@OpenWrt:~# opkg install shadow-useradd root@OpenWrt:~# mkdir /home root@OpenWrt:~# useradd -D GROUP=100 HOME=/home INACTIVE=-1 EXPIRE= SHELL= SKEL=/etc/skel CREATE_MAIL_SPOOL=no root@OpenWrt:~# useradd -m -s /bin/ash bart root@OpenWrt:~# cat /etc/passwd root:x:0:0:root:/root:/bin/ash daemon:*:1:1:daemon:/var:/bin/false ftp:*:55:55:ftp:/home/ftp:/bin/false network:*:101:101:network:/var:/bin/false nobody:*:65534:65534:nobody:/var:/bin/false bart:x:1000:1000::/home/bart:/bin/ash root@OpenWrt:~# passwd bart Changing password for ...

Dropbear SSH keys and autossh on OpenWRT

Image
I have a box on Amazon EC2. And I want to have my OpenWRT that is behind IPv4 CGN and have public IPv6 to be reachable from IPv4 Internet. The best idea is to use ssh reverse tunnel connected with autossh to keep connection going. The very first think is to test if I can connect to my Amazon instance from my OpenWRT: root@OpenWrt:~# ssh 54.111.111.111 Host '54.111.111.111' is not in the trusted hosts file. (ssh-rsa fingerprint md5 0f:51:11:11:11:11:11:11:11:11:11:11:11:11:11:11) Do you want to continue connecting? (y/n) y root@54.111.111.111's password: At this point the public key of remote host will be added to .ssh/known_hosts. It is important as we can't have autossh to interact with console in future. root@OpenWrt:~# cat .ssh/known_hosts 2001:1111:1111:1111::1111:1111 ssh-rsa AAAAB3N....... 54.111.111.111 ssh-rsa AAAAB3N.......... Now we need to generate public/private key pair we will be using to connect to our Amazon instance. Invoke fol...

SSH Tunel with OpenWRT

You need to install OpenSSH client: root@OpenWrt:~# opkg update root@OpenWrt:~# opkg install openssh-client Now OpenSSH client replaced DropBear client: root@OpenWrt:~# ls -l /usr/bin/ssh -rwxr-xr-x    1 root     root        590667 May 24 14:54 /usr/bin/ssh root@OpenWrt:~# ls -l /rom/usr/bin/ssh lrwxrwxrwx    1 root     root            16 Aug 19  2016 /rom/usr/bin/ssh -> ../sbin/dropbear root@OpenWrt:~# ls -l /overlay/upper/usr/bin/ssh -rwxr-xr-x    1 root     root        590667 May 24 14:54 /overlay/upper/usr/bin/ssh Can you spot a difference: root@OpenWrt:~# ssh usage: ssh [-1246AaCfGgKkMNnqsTtVvXxYy] [-b bind_address] [-c cipher_spec]            [-D [bind_address:]port] [-E log_file] [-e escape_char]            [-F configfile] [-I pkcs11] [-i identity_file...
