Setting Up an NFS Server in Ubuntu

You may need to setup an NFS server on Ubuntu to run and debug your program on your target platform or simply to share media files on the network composed of Linux clients. If you are using Windows clients, you would usually use SAMBA/CIFS, although it is possible to setup an NFS server in Windows as well using Windows Services for UNIX 3.5. Quick Guide to to setup an NFS server in Ubuntu without authentication. Install the required packages: # sudo apt-get install nfs-kernel-server nfs-common portmap Reconfigure and restart portmap: # sudo dpkg-reconfigure portmap # sudo /etc/init.d/portmap restart Edit /etc/exports: # sudo vi /etc/exports Add the directories to share with NFS and save the file, for example: /nfs 192.168.1.0/24(rw,no_root_squash,async) will give full read/write permissions to the nfs directory for computer in 192.168.1.0 subnet. Restart the NFS server: # sudo /etc/init.d/nfs-kernel-server restart and reload the configuration: # sudo exportfs -a The […]

Cross compiling Berkeley DB for ARM and MIPS

Following my blog entry about Databases for Linux Embedded Systems, here are the instructions to cross-compile Oracle Berkeley DB. First download the source code of the latest version of Berkeley DB (version 11gR2 – 11.2.5.1.25). You’ll need to register on Oracle website first on the download page http://www.oracle.com/technetwork/database/berkeleydb/downloads/index.html to download http://download.oracle.com/otn/berkeley-db/db-5.1.25.tar.gz (with AES encryption) or http://download.oracle.com/otn/berkeley-db/db-5.1.25.NC.tar.gz (if you don’t need encryption). Extract the source code: tar xzvf ../Downloads/db-5.1.25.tar.gz Configure and build the source code. I’ll use mipsel-linux-gcc, but any other cross-compiler could be used. cd db-5.1.25/build_unix ../dist/configure –host=mipsel-linux CC=mipsel-linux-gcc RANLIB=mipsel-linux-ranlib STRIP=mipsel-linux-strip AR=mipsel-linux-ar –prefix=/home/jaufranc/edev/lib/db-11g make make install The full berkeley DB package is 79MB: jaufranc@CNX-TOWER:~/edev/lib/db-11g$ du –max-depth=1 -h 6.6M ./lib 308K ./bin 72M ./docs 176K ./include 79M . However, you won’t need the include and docs directory in your embedded target. So you do not need to copy those. You may or may need the utilities in the bin file. The […]
