tftp is Multi-threaded TFTP server implementing all options (option
extension and multicast) as specified in RFC1350, RFC2090, RFC2347,
RFC2348 and RFC2349. Atftpd also supports multicast protocol known as
mtftp, defined in the PXE specification. The server supports being
started from inetd as well as in daemon mode using init scripts.
Install atftp Server in Ubuntu
sudo aptitude install atftpd
This will complete the installation
Using atftpd
By default atftpd server starts using inetd so we need to tell atftpd to run as a server directly, not through inetd.Edit /etc/default/atftpd file using the following command
sudo gedit /etc/default/atftpd
Change the following line
USE_INETD=true
to
USE_INETD=false
save and exit the file
Now you need to run the following command
sudo invoke-rc.d atftpd start
Configuring atftpd
First you need to create a directory where you can place the files
sudo mkdir /tftpboot
sudo chmod -R 777 /tftpboot
sudo chown -R nobody /tftpboot
sudo /etc/init.d/atftpd restart
Security configuration for atftp
Some level of security can be gained using atftp libwrap support. Adding proper entry to /etc/hosts.allow and /etc/hosts.deny will restrict access to trusted hosts. Daemon name to use in these files is in.tftpd.
/etc/hosts.allow /etc/hosts.deny
in.tftpd : FQD or IP
atftp client installation
Advance Trivial file transfer protocol client,atftp is the user interface to the Internet ATFTP (Advanced Trivial File Transfer Protocol), which allows users to transfer files to and from a remote machine. The remote host may be specified on the command line, in which case atftp uses host as the default host for future transfers.
sudo aptitude install atftp
That’s it you are ready to transfer your files using tftp clients
Testing tftp server
Tranfering file hda.txt from 192.168.1.100 (Client using tftp) to 192.168.1.2 (Server 192.168.1.100). Get an example file to transfer (eg. hda.txt)
cd /srv/tftp
touch test.txt
ls -l /srv/tftp/
total 0
-rwxrwxrwx 1 ruchi ruchi 223 test.txt
cd /tmp
atftp 192.168.1.2
atftp> get test.txt
Sent 722 bytes in 0.0 seconds
atftp> quit
ls -l /tmp/
total 4
-rwxrwxrwx 1 ruchi ruchi 707 2008-07-07 23:07 test.txt
紅色部分 為阿謙改寫, 主要是 因為 ubuntu 10.10 在安裝 atftpd 時 ,
就會在 /srv/ 目錄下建立名稱為 tftp 的子目錄.
該子目錄為 atftpd 預設的根目錄.
透過 atftpd 的 put 上傳 或 get 下傳 的 檔案 都會放在這裡
簡單點講 ,就是如果你要透過 tftp 傳輸檔案 ,則只要把檔案放在 /src/tftpd 目錄下即可
