Here are some things you might have to do on wangari.

Add a new web volunteer for a local

Check ownership of the local's directory. Count the files in the directory, then search for files not belonging to the right group or with inadequate permissions.

 ls -ld /w/cal/contracosta
 find /w/cal/contracosta  -group  contracosta | wc -l
 find /w/cal/contracosta \! -group  contracosta
 find /w/cal/contracosta  -type d \! -perm -775 | wc -l

If the '-perm' test gives a non-zero answer, fix the offending plain file or directory

 find /w/cal/contracosta  -type d \! -perm -775 | tail
 chmod ug+w,o-w /w/cal/contracosta/foobar.shtml
 chmod ug+w,o-w,a+x,g+s /w/cal/contracosta/foo/bar/baz/

We're setting write for the user and group and clearing it for others. Setting "search" (x) for everyone. Setting "set group-ID". The "set group-ID" bit tells the kernel any new file here must be created with the same user-ID and group-ID as this directory has. It has the effect that three different people creating files in the directory will all be creating files that belong to the "contracosta" group.

Check new volunteer's groups and add her or him to the right one.

 gpw bert
 gpw bheurer
 gpw contracosta
 adduser bheurer contracosta



Be the mailman user and archive and remove an unwanted mailman list

As root,

 su - list

which gives you a login shell as Mr. list. First remind yourself where Mailman is. Try the tab key instead of asterisk there.

 egrep 'cgi-bin|piperm' /etc/apa*/sites-a*/wa* | grep -v '^#'

Then do stuff. Keep the name of the list in a shell variable to avoid typing it over and over.

 cd /var/lib/mailman
 bye=humboldt-discuss
 file  archives/private/$bye*
 cp -a lists/$bye ~/oldlists/lists
 cp -a archives/private/$bye* ~/oldlists/archives
 ls -l data/al*
 ls bin
 bin/rmlist -a $bye
 ls -l data/al*

Now it's gone. After a minute or two, Postfix will notice the change and forget about the former list's addresses. You don't have to signal it.
