Do you have the right permissions on /tmp ?

# ls -ld /tmp
drwxrwxrwt 12 root root 12288 Feb  9 12:53 /tmp

(note the 't'; this is mode 1777). If that's correct, try rm -rf /tmp/netdisco-mibs in case this directory was already created, and then retry.

Permission are OK, netdisco-mibs-install needs only write permissions

# ls -ld /tmp/netdisco-mibs
drwxr-xr-x 2 root root 60 úno  9 13:20 /tmp/netdisco-mibs

The problem is stat application used by netdisco-mibs-install They do this

if ! stat $BASEDIR|grep '^Access:.*drwx.-..-.'>/dev/null; then
    echo >&2 "$0: error: Should be writable only by root: $BASEDIR"
    exit 3
fi

This is output of stat with LANG=cs_CZ.UTF-8

# LANG=cs_CZ.UTF-8 stat /tmp/netdisco-mibs

as you can see there is nohing to be found by grep '^Access:.*drwx.-..-.

Output with LANG=C is another case

# LANG=C stat /tmp/netdisco-mibs

This is parsable by grep '^Access:.*drwx.-..-.' and works for netdisco-mibs-install

[candlerb]

The problem is stat application used by netdisco-mibs-install

They do this...

Oh, yukkety yuk! They could at least have used stat --format %A /tmp/netdisco-mibs

Anyway, now I understand why your workaround is needed. Thanks.

[qaxi]

Yes, more common bash construct works the same way

cd /tmp
mkdir qqq bbb
chmod 555 qqq
chmod 755 bbb
for i in qqq bbb
do
   echo -n "Directory $i "
   if [ -d "$i" -a -w "$i" ]
   then
      echo "- writable"
   else
      echo "- non writable"
   fi
done

[candlerb]

The trouble with test -w ... (or bash [ -w ... ]) is that it just says if it's writeable by you. The netdisco code was trying to check if it was writeable by anyone else.

[qaxi]

IMHO I read this from netdisco-mibs-install

stat $BASEDIR|grep '^Access:.*drwx.-..-.'>/dev/null

And it looks for me like they do not care about group or others permissions

[candlerb]

That line checks that the "group write" and "other write" flags are both "-" (dash), i.e. disabled. The dots match any character in the other positions, meaning they don't care about group/other read/execute.

In long-hand:

"Access:" <zero-or-more-any> "drwx" <any-single-char> "-" <any-single-char> <any-single-char> "-" <any-single-char>
