416fd2a8 | 1 | This file contains notes about OpenSSH on specific platforms. |
2 | ||
3 | AIX | |
4 | --- | |
5 | As of OpenSSH 3.8p1, sshd will now honour an accounts password expiry | |
6 | settings, where previously it did not. Because of this, it's possible for | |
7 | sites that have used OpenSSH's sshd exclusively to have accounts which | |
8 | have passwords expired longer than the inactive time (ie the "Weeks between | |
9 | password EXPIRATION and LOCKOUT" setting in SMIT or the maxexpired | |
10 | chuser attribute). | |
11 | ||
12 | Accounts in this state must have their passwords reset manually by the | |
13 | administrator. As a precaution, it is recommended that the administrative | |
14 | passwords be reset before upgrading from OpenSSH <3.8. | |
15 | ||
34fee935 | 16 | As of OpenSSH 4.0, configure will attempt to detect if your version |
17 | and maintenance level of AIX has a working getaddrinfo, and will use it | |
18 | if found. This will enable IPv6 support. If for some reason configure | |
19 | gets it wrong, or if you want to build binaries to work on earlier MLs | |
20 | than the build host then you can add "-DBROKEN_GETADDRINFO" to CFLAGS | |
21 | to force the previous IPv4-only behaviour. | |
22 | ||
23 | IPv6 known to work: 5.1ML7 5.2ML2 5.2ML5 | |
24 | IPv6 known broken: 4.3.3ML11 5.1ML4 | |

26 | Cygwin | |
27 | ------ | |
28 | To build on Cygwin, OpenSSH requires the following packages: | |
29 | gcc, gcc-mingw-core, mingw-runtime, binutils, make, openssl, | |
30 | openssl-devel, zlib, minres, minires-devel. | |
31 | ||

2e437378 | 33 | Darwin and MacOS X |
34 | ------------------ | |
35 | Darwin does not provide a tun(4) driver required for OpenSSH-based | |
36 | virtual private networks. The BSD manpage still exists, but the driver | |
37 | has been removed in recent releases of Darwin and MacOS X. | |
38 | ||
39 | Nevertheless, tunnel support is known to work with Darwin 8 and | |
40 | MacOS X 10.4 in Point-to-Point (Layer 3) and Ethernet (Layer 2) mode | |
41 | using a third party driver. More information is available at: | |
42 | http://www-user.rhrk.uni-kl.de/~nissler/tuntap/ | |

416fd2a8 | 45 | Solaris |
46 | ------- | |
34fee935 | 47 | If you enable BSM auditing on Solaris, you need to update audit_event(4) |
48 | for praudit(1m) to give sensible output. The following line needs to be | |
49 | added to /etc/security/audit_event: | |
50 | ||
51 | 32800:AUE_openssh:OpenSSH login:lo | |
52 | ||
53 | The BSM audit event range available for third party TCB applications is | |
54 | 32768 - 65535. Event number 32800 has been choosen for AUE_openssh. | |
55 | There is no official registry of 3rd party event numbers, so if this | |
56 | number is already in use on your system, you may change it at build time | |
57 | by configure'ing --with-cflags=-DAUE_openssh=32801 then rebuilding. | |

e00da40d | 60 | Platforms using PAM |
61 | ------------------- | |
62 | As of OpenSSH 4.3p1, sshd will no longer check /etc/nologin itself when | |
63 | PAM is enabled. To maintain existing behaviour, pam_nologin should be | |
64 | added to sshd's session stack which will prevent users from starting shell | |
65 | sessions. Alternatively, pam_nologin can be added to either the auth or | |
66 | account stacks which will prevent authentication entirely, but will still | |
67 | return the output from pam_nologin to the client. | |
