CentOS 7, Man

CentOS 2 Comments

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.

    Thanks for the suggestion. The thing that bothers me is why this should happen at all….
