1. 下載需要的源碼: mkdir -p ~/arm/fs ;mkdir -p ~/arm/source 下載zlib: wget -c http://www./zlib-1.2.3.tar.gz 下載ssl: wget -c http://www./source/openssl-0.9.8d.tar.gz 下載ssh: wget -c http://mirror.mcs./openssh/portable/openssh-4.6p1.tar.gz 2. 編譯: cd ~/arm/source (1) 編譯zlib: tar zxvf zlib-1.2.3.tar.gz -C . cd zlib-1.2.3/ ./configure --prefix=/home/david/fs/zlib-1.2.3 修改Makefile: CC=gcc 改為: CROSS=arm-linux- CC=$(CROSS)gcc LDSHARED=gcc 改為: LDSHARED=$(CROSS)gcc CPP=gcc -E 改為: CPP=$(CROSS)gcc -E AR=ar rc 改為: AR=$(CROSS)ar rc 開始編譯: make; make install (2) 編譯openssl: tar zxvf openssl-0.9.8d.tar.gz ./Configure --prefix=/home/david/fs/openssl-0.9.8d os/compiler:arm-linux-gcc make make install (3) 編譯openssh: tar zxvf openssh-4.6p1.tar.gz cd openssh-4.6p1/ ./configure --host=arm-linux --with-libs --with-zlib=/home/linksens/tools/fs/zlib-1.2.3 --with-ssl-dir=/home/david/fs/openssl-0.9.8d --disable-etc-default-login CC=arm-linux-gcc AR=arm-linux-ar make ##不要make install 3. 安裝 (1) 將 openssh-4.6p1目錄下的 sshd 拷貝到 目標板的/usr/sbin目錄下 (2) 再copy scp sftp ssh ssh-add ssh-agent ssh-keygen ssh-keyscan 到目標板/usr/local/bin目錄下 copy sftp-server ssh-keysign 到/usr/local/libexec (3) 在目標板下： mkdir -p /usr/local/etc/ 然后將openssh下的sshd_config,ssh_config 拷貝到該目錄下 mkdir -p /var/run; mkdir -p /var/empty/sshd chmod 755 /var/empty （4）在主機上： ssh-keygen -t rsa1 -f ssh_host_key -N "" ssh-keygen -t rsa -f ssh_host_rsa_key -N ""ssh-keygen -t dsa -f ssh_host_dsa_key -N ""遇到問題：1 Permissions 0644 for '/usr/local/etc/ssh_host_key' are too open此為文件的權限問題，解決方法為： # cd /usr/local/etc # ls moduli ssh_config # ls -l total 194 -rwxr-xr-x -rwxr-xr-x -rwxr-xr-x -rwxr-xr-x -rwxr-xr-x -rwxr-xr-x -rwxr-xr-x -rwxr-xr-x -rwxr-xr-x # chmod 0644 * # ls -l total 194 -rw-r--r-- -rw-r--r-- -rw-r--r-- -rw-r--r-- -rw-r--r-- -rw-r--r-- -rw-r--r-- -rw-r--r-- -rw-r--r-- # chmod 0600 ssh_host_dsa_key # ls -l total 194 -rw-r--r-- -rw-r--r-- -rw------- -rw-r--r-- -rw------- -rw-r--r-- -rw------- -rw-r--r-- -rw-r--r-- 2 在ssh目標機時出現 ssh root@192.168.237.239 @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY! Someone could be eavesdropping on you right now (man-in-the-middle attack)! It is also possible that the RSA host key has just been changed. The fingerprint for the RSA key sent by the remote host is 97:ff:ec:78:48:69:c0:61:1d:82:9b:6c:2e:6b:6b:46. Please contact your system administrator. Add correct host key in /root/.ssh/known_hosts to get rid of this message. Offending key in /root/.ssh/known_hosts:11 RSA host key for 192.168.237.239 has changed and you have requested strict checking. Host key verification failed. 警告中已經說 |
