This is... odd.
From my workstation, where I'm directly logged in, if I ssh to any CentOS 7 box, as myself, and try to run man, it fails. Example 1: man dd man: cannot write to /var/cache/man/cat1/dd.1.gz in catman mode dd.
Example 2: man dd man: can't chmod (null): Bad address man: can't unlink (null): Bad address dd.
In all cases, if I sudo -s to root, I have no trouble reading the manpage. In all cases I've tried, selinux is in permissive mode.
From one of these boxes: ls -laF /var/cache/man/ | more total 832 drwxr-xr-x. 38 root root 4096 Jan 27 07:52 ./ drwxr-xr-x. 9 root root 105 Dec 28 12:42 ../ -rw-r--r--. 1 root root 190 Dec 28 13:18 CACHEDIR.TAG drwxr-xr-x. 4 root root 62 Jan 27 07:52 ca/ drwxr-xr-x. 2 root root 20 Jan 27 11:27 cat1/ <...>
But it's the same in CentOS 6. Clues?
I've had NOCACHE set in /etc/man.config for a long time. On a modern machine there's not that much overhead generating the text page on demand, and eliminating that avoids issues with pages formatted for one window size being viewed on another.
