| 2 | ---------------- |
| 3 | |
| 4 | You will need working installations of Zlib and OpenSSL. |
| 5 | |
| 6 | Zlib: |

| 8 | |
| 9 | OpenSSL: |
| 10 | http://www.openssl.org/ |
| 11 | |
| 12 | OpenSSH can utilise Pluggable Authentication Modules (PAM) if your system |
| 13 | supports it. PAM is standard on Redhat and Debian Linux and on Solaris. |

| 19 | http://www.inet.no/dante |
| 20 | |
| 21 | OpenSSH can also use the Dante SOCKS libraries, version 1.1.1pre1 or higher, |
| 22 | if you have them installed on your system. |

| 26 | |

Damien Miller | b5f8927 | 1999-11-12 14:35:58 +1100 | [diff] [blame] | 36 | If you are planning to use OpenSSH on a Unix which lacks a Kernel random |
| 37 | number generator (/dev/urandom), you will need to install the Entropy |
| 38 | Gathering Daemon (or similar). You will also need to specify the |
| 39 | --with-egd-pool option to ./configure. |
| 40 | |

| 45 | ftp://ftp.gnu.org/gnu/make/ |
| 46 | |
| 47 | OpenSSH has only been tested with GNU make. It may work with other |
| 48 | 'make' programs, but you are on your own. |
Damien Miller | b5f8927 | 1999-11-12 14:35:58 +1100 | [diff] [blame] | 49 | |
| 50 | 2. Building / Installation |
| 51 | -------------------------- |
| 52 | |
| 53 | To install OpenSSH with default options: |
| 54 | |
| 55 | ./configure |
| 56 | make |
| 57 | make install |
| 58 | |
| 59 | This will install the OpenSSH binaries in /usr/local/bin, configuration files |
| 60 | in /usr/local/etc, the server in /usr/local/sbin, etc. To specify a different |
| 61 | installation prefix, use the --prefix option to configure: |
| 62 | |
| 63 | ./configure --prefix=/opt |
| 64 | make |
| 65 | make install |
| 66 | |
| 67 | Will install OpenSSH in /opt/{bin,etc,lib,sbin}. You can also override |
| 68 | specific paths, for example: |
| 69 | |
| 70 | ./configure --prefix=/opt --sysconfdir=/etc/ssh |
| 71 | make |
| 72 | make install |
| 73 | |
| 74 | This will install the binaries in /opt/{bin,lib,sbin}, but will place the |
| 75 | configuration files in /etc/ssh. |
| 76 | |
Damien Miller | 294df78 | 1999-11-23 10:11:29 +1100 | [diff] [blame] | 77 | If you are using PAM, you will need to manually install a PAM control |
| 78 | file as "/etc/pam.d/sshd" (or wherever your system prefers to keep |
| 79 | them). A generic PAM configuration is included as "sshd.pam.generic", |
| 80 | you may need to edit it before using it on your system. |
Damien Miller | 755c90c | 1999-11-22 16:12:31 +1100 | [diff] [blame] | 81 | |
Damien Miller | b5f8927 | 1999-11-12 14:35:58 +1100 | [diff] [blame] | 82 | There are a few other options to the configure script: |
| 83 | |
Damien Miller | 8bdeee2 | 1999-12-30 15:50:54 +1100 | [diff] [blame] | 84 | --with-rsh=PATH allows you to specify the path to your rsh program. |
| 85 | Normally ./configure will search the current $PATH for 'rsh'. You |
| 86 | may need to specify this option if rsh is not in your path or has a |
| 87 | different name. |
| 88 | |
| 89 | --without-pam will disable PAM support. PAM is automatically detected |
| 90 | and switched on if found. |
| 91 | |
Damien Miller | c096727 | 1999-11-19 15:53:50 +1100 | [diff] [blame] | 92 | --enable-gnome-askpass will build the GNOME passphrase dialog. You |
| 93 | need a working installation of GNOME, including the development |
| 94 | headers, for this to work. |
Damien Miller | b5f8927 | 1999-11-12 14:35:58 +1100 | [diff] [blame] | 95 | |
Damien Miller | c096727 | 1999-11-19 15:53:50 +1100 | [diff] [blame] | 96 | --with-random=/some/file allows you to specify an alternate source of |
| 97 | random numbers (the default is /dev/urandom). Unless you are absolutly |
Damien Miller | b5f8927 | 1999-11-12 14:35:58 +1100 | [diff] [blame] | 98 | sure of what you are doing, it is best to leave this alone. |
| 99 | |
Damien Miller | c096727 | 1999-11-19 15:53:50 +1100 | [diff] [blame] | 100 | --with-egd-pool=/some/file allows you to enable Entropy Gathering |
| 101 | Daemon support and to specify a EGD pool socket. You will need to |
| 102 | use this if your Unix does not support the /dev/urandom device (or |
Damien Miller | ab8a4da | 1999-12-16 13:05:30 +1100 | [diff] [blame] | 103 | similar). The file argument refers to the EGD pool file, not the |
| 104 | EGD program itself. Please refer to the EGD documentation. |
Damien Miller | b5f8927 | 1999-11-12 14:35:58 +1100 | [diff] [blame] | 105 | |
Damien Miller | 8bdeee2 | 1999-12-30 15:50:54 +1100 | [diff] [blame] | 106 | --with-lastlog=FILE will specify the location of the lastlog file. |
| 107 | ./configure searches a few locations for lastlog, but may not find |
| 108 | it if lastlog is installed in a different place. |
| 109 | |
| 110 | --without-lastlog will disable lastlog support entirely. |
| 111 | |
Damien Miller | 105b7f0 | 2000-01-07 08:45:55 +1100 | [diff] [blame] | 112 | --with-kerberos4=PATH will enable Kerberos IV support. You will need |
| 113 | to have the Kerberos libraries and header files installed for this |
| 114 | to work. Use the optional PATH argument to specify the root of your |
| 115 | Kerberos installation. |
Damien Miller | c096727 | 1999-11-19 15:53:50 +1100 | [diff] [blame] | 116 | |
Damien Miller | 105b7f0 | 2000-01-07 08:45:55 +1100 | [diff] [blame] | 117 | --with-afs=PATH will enable AFS support. You will need to have the |
| 118 | Kerberos IV and the AFS libraries and header files installed for this |
| 119 | to work. Use the optional PATH argument to specify the root of your |
| 120 | AFS installation. AFS requires Kerberos support to be enabled. |
Damien Miller | c096727 | 1999-11-19 15:53:50 +1100 | [diff] [blame] | 121 | |
| 122 | --with-skey will enable S/Key one time password support. You will need |
| 123 | the S/Key libraries and header files installed for this to work. |
| 124 | |
| 125 | --with-tcp-wrappers will enable TCP Wrappers (/etc/hosts.allow|deny) |
| 126 | support. You will need libwrap.a and tcpd.h installed. |
| 127 | |
| 128 | --with-md5-passwords will enable the use of MD5 passwords. Enable this |
| 129 | if your operating system uses MD5 passwords without using PAM. |
Damien Miller | 3d1b22c | 1999-11-12 15:46:08 +1100 | [diff] [blame] | 130 | |
Damien Miller | 8bdeee2 | 1999-12-30 15:50:54 +1100 | [diff] [blame] | 131 | --with-utmpx enables utmpx support. utmpx support is automatic for |
| 132 | some platforms. |
| 133 | |
| 134 | --without-shadow disables shadow password support. |
| 135 | |
| 136 | --with-ipaddr-display forces the use of a numeric IP address in the |
| 137 | $DISPLAY environment variable. Some broken systems need this. |
| 138 | |
| 139 | --with-default-path=PATH allows you to specify a default $PATH for sessions |
| 140 | started by sshd. |
| 141 | |
| 142 | --with-dante[=DIR] will enable Dante SOCKS library support. If the Dante |
| 143 | libsocks library isn't installed in a library searched by the compiler, |
| 144 | add the directory name as the option. |
| 145 | |
Damien Miller | beb4ba5 | 1999-12-28 15:09:35 +1100 | [diff] [blame] | 146 | If you need to pass special options to the compiler or linker, you |
| 147 | can specify these as enviornment variables before running ./configure. |
| 148 | For example: |
| 149 | |
| 150 | CFLAGS="-O -m486" LFLAGS="-s" ./configure |
Damien Miller | b5f8927 | 1999-11-12 14:35:58 +1100 | [diff] [blame] | 151 | |
| 152 | 3. Configuration |
| 153 | ---------------- |
| 154 | |
| 155 | The runtime configuration files are installed by in ${prefix}/etc or |
| 156 | whatever you specified as your --sysconfdir (/usr/local/etc by default). |
| 157 | |
| 158 | The default configuration should be instantly usable, though you should |
| 159 | review it to ensure that it matches your security requirements. |
| 160 | |
Damien Miller | 2a9d9f6 | 1999-11-15 23:34:11 +1100 | [diff] [blame] | 161 | To generate a host key, issue the following command: (replacing |
| 162 | /etc/ssh/ssh_host_key with an appropriate path) |
| 163 | |
| 164 | /usr/bin/ssh-keygen -b 1024 -f /etc/ssh/ssh_host_key -N '' |
| 165 | |
Damien Miller | 6ae00d6 | 1999-12-14 15:43:03 +1100 | [diff] [blame] | 166 | Replacing /etc/ssh with the correct path to the configuration directory. |
| 167 | (${prefix}/etc or whatever you specified with --sysconfdir during |
| 168 | configuration) |
| 169 | |
Damien Miller | ab8a4da | 1999-12-16 13:05:30 +1100 | [diff] [blame] | 170 | If you have configured OpenSSH with EGD support, ensure that EGD is |
| 171 | running and has collected some Entropy. |
| 172 | |
Damien Miller | b5f8927 | 1999-11-12 14:35:58 +1100 | [diff] [blame] | 173 | For more information on configuration, please refer to the manual pages |
| 174 | for sshd, ssh and ssh-agent. |
