The reason for that code seems to be some ancient AIX version that defined a value that was too small (32). We don't support such systems. In the link below, I found the following comment and code: /* * Some AIX versions advertise a too small MAXHOSTNAMELEN value (32). * Result: long hostnames would be truncated, and connections would be * dropped because of host name verification failures. Adrian van Bloois * (A.vanBloois@info.nic.surfnet.nl) figured out what was the problem. */ #if (MAXHOSTNAMELEN < 64) #undef MAXHOSTNAMELEN #endif /* In case not defined in <sys/param.h>. */ #ifndef MAXHOSTNAMELEN #define MAXHOSTNAMELEN 256 /* storage for host name */ #endif Today's systems seem to be much better regarding this macro. Rely on them. Link: <https://sources.debian.org/src/tcp-wrappers/7.6.q-33/workarounds.c/?hl=36#L36> Signed-off-by: Alejandro Colomar <alx@kernel.org>
shadow-utils
Introduction
The shadow-utils package includes the necessary programs for converting UNIX password files to the shadow password format, plus programs for managing user and group accounts. The pwconv command converts passwords to the shadow password format. The pwunconv command unconverts shadow passwords and generates a passwd file (a standard UNIX password file). The pwck command checks the integrity of password and shadow files. The lastlog command prints out the last login times for all users. The useradd, userdel, and usermod commands are used for managing user accounts. The groupadd, groupdel, and groupmod commands are used for managing group accounts.
