inetutils

including ftpd, inetd, rexecd, rlogind, rshd, talkd, telnetd, tftpd, uucpd and whois
inetutils-1.5.tar.gz is in the lfs-6.3 live cd

./configure --prefix=/usr --libexecdir=/usr/sbin --sysconfdir=/etc --localstatedir=/var --mandir=/usr/share/man --infodir=/usr/share/info --disable-clients --disable-logger --disable-syslogd

root [ /mnt/sdb1/src/inetutils-1.5 ]# cat /etc/inetd.conf

tftp           dgram   udp   wait   root  /usr/sbin/tftpd       -l /boot

samba installation and setup

1. install

sudo apt-get install samba

sudo apt-get install smbfs

1. create user and directory

useradd testuser

smbpasswd -a testuser

mkdir /test/testdir

chown testuser /test/testdir

1. configure samba
   vi /etc/samba/smb.conf, append the following line:

testuser = "user for testing"

vi /etc/samba/smb.conf, append the following line:

security = user

username map = /etc/samba/smbusers

usershare allow guests = yes

[testfolder]

       path = /media/disk/testdir

       public = no

       writeable = yes

       browseable = yes

1. (re)start samba

/etc/init.d/samba restart

tftp/ftp等服务器的安装

这些都是inetutils工具的一部分。

inetutils-1.5在2.6.32.27下工作不正常，不能接受外部tftp请求。

inetutils-1.9.2和1.9.3都没问题，且可以支持带802.1q vlan tag的端口。

下载链接：ftp://ftp.gnu.org/gnu/inetutils/

如果./configure的时候不加参数，则make;make install后，

只需要增加一个文件：/etc/inetd.conf，内容如下：

tftp dgram udp wait root /usr/local/libexec/tftpd -l /boot

启动inetd即可：/usr/local/libexec/inetd，无需单独启动具体服务

tftp的日志，会记录在/var/log/sys.log中。

常用工具

tcpdump (已在lfs 6.3验证)
tcpdump-4.1.1.tar.gz (changelog) (PGP signature)
libpcap-1.1.1.tar.gz (changelog) (PGP signature)
minicom(已在lfs 6.3验证)
minicom-2.7.tar.gz

SSH

sshd服务：service sshd start/restart/stop
sshd服务调试版本：sshd -d [-d [-d]]

安装grub（以/dev/hda为例）:

grub-install /dev/hda
如果提示/dev/hda does not have any corresponding BIOS drive
则先运行grub-install --recheck /dev/hda

linux下配置FTP

1.新建一个用户（非root用户）;
2.编辑/etc/xinted.d/wu-ftpd文件，将disable=yes改成no，然后重启系统即可。

ftp整个目录上传/下载

如果在文字界面中用ftp命令进入服务器后,先用prompt命令关掉提示.然后用mget和mput命令就可以了,在xwindow下可以用gftp,和windows下的cuteftp等ftp客户端程序差不多.

关闭debian默认启动图形界面
