〖Linux〗build ssh for Arm
1. 交叉编译环境：
export ARCH=arm export SUBARCH=arm export PATH=/opt/FriendlyARM/toolschain/4.5.1/bin:$PATH export CROSS_COMPILE=/opt/FriendlyARM/toolschain/4.5.1/bin/arm-linux-
2. 安装依赖环境：
sudo aptitude install zlib1g-dev libssl-dev
3. 编译 zlib for ARM: 版本[zlib-1.2.8.tar.gz]
./configure --prefix=/opt/FriendlyARM/zlib make -j4 -e \ "CC=arm-linux-gcc" \ "AR=arm-linux-ar" \ "CPP=arm-linux-gcc -E" \ "LDSHARED=arm-linux-gcc -shared -Wl,-soname,libz.so.1,--version-script,zlib.map" make install # 要求/opt目录的所有者为当前用户
4. 编译 openssl: 版本[openssl-1.0.1e.tar.gz]
unset CROSS_COMPILE #必须执行的命令！ ./Configure --prefix=/opt/FriendlyARM/openssl os/compiler:arm-linux-gcc make -j4 make install
5. 编译 openssh: openssh-6.3p1.tar.gz
./configure --prefix=/opt/FriendlyARM/openssh \ --host=arm-linux \ --with-zlib=/opt/FriendlyARM/zlib \ --with-ssl-dir=/opt/FriendlyARM/openssl \ CC=arm-linux-gcc make -j4 # 不需要make install，安装不上的!!
>>在PC打包ssh成为一个tar包：
#!/bin/sh - tmpdir=tmp_arm prefix=/opt/FriendlyARM/openssh mkdir $tmpdir mkdir -p $tmpdir/$prefix/etc mkdir -p $tmpdir/$prefix/bin mkdir -p $tmpdir/$prefix/etc mkdir -p $tmpdir/$prefix/libexec mkdir -p $tmpdir/$prefix/sbin ssh-keygen -t rsa -f ssh_host_rsa_key -N "" ssh-keygen -t dsa -f ssh_host_dsa_key -N "" ssh-keygen -t ecdsa -f ssh_host_ecdsa_key -N "" cp ssh_host_*_key $tmpdir/$prefix/etc/ cp scp sftp ssh ssh-add ssh-agent ssh-keygen ssh-keyscan $tmpdir/$prefix/bin/ cp moduli ssh_config sshd_config $tmpdir/$prefix/etc/ cp sftp-server ssh-keysign $tmpdir/$prefix/libexec/ cp sshd $tmpdir/$prefix/sbin/ cd $tmpdir tar zcf ssh_arm.tgz /opt/FriendlyARM/openssl /opt/FriendlyARM/zlib *
>>把tar包拷贝至ARM板后，安装过程：
#!/bin/sh - # run on arm tar zxf ssh_arm.tgz -C / echo 'PATH=/opt/FriendlyARM/openssh/bin:/opt/FriendlyARM/openssh/sbin:$PATH' >> /etc/profile echo 'sshd:x:74:74:Privilege-separated SSH:/var/empty/sshd:/sbin/nologin' >> /etc/passwd source /etc/profile
>> 效果展示：先在ARM板上执行 /opt/FriendlyARM/openssh/sbin/sshd
这表明已经成功通过ssh连接至ARM开发板了。
