chpasswd in an OpenBSD apache chroot jail

I’ve recently re-installed OpenBSD and had to set-up my squid intranet password changing tool again. The app I use is chpasswd Version 2.2.3.

I had some trouble with getting it working in the default apache chroot jail, and found very little information out there on this app in a chroot jail. Here are my notes I recorded and and steps I took. Hope it helps someone else, but YMMV:

Download chpasswd to /tmp
<br /> cd /tmp<br /> tar -zxvf chpasswd-2.2.3.tar.gz<br /> cd chpasswd-2.2.3<br /> ./configure --enable-cgidir=/var/www/cgi-bin/ --prefix=/etc<br /> make && make install<br /> make clean<br />
Setup apache for CGI running in the chroot jail
<br /> mkdir /var/www/etc<br /> mkdir /var/www/tmp<br /> mkdir -p /var/www/var/tmp<br /> chmod 777 /var/www/tmp<br /> chmod 777 /var/www/var/tmp<br /> mv /etc/chpasswd* /var/www/etc/<br />
Check which libs are compiled against chpasswd
<br /> ldd /var/www/cgi-bin/chpasswd.cgi<br />
Output should be similar to the following:
<br /> /var/www/cgi-bin/chpasswd.cgi:<br /> Start End Type Ref Name<br /> 00000000 00000000 exe 1 /var/www/cgi-bin/chpasswd.cgi<br /> 03d1e000 23d4f000 rlib 1 /usr/lib/<br /> 09e55000 09e55000 rtld 1 /usr/libexec/<br />
Copy the libs that chpasswd.cgi uses, shown from the ldd output, to the jail
<br /> mkdir -p /var/www/usr/lib<br /> mkdir -p /var/www/usr/libexec<br /> cp /usr/lib/ /var/www/usr/lib/<br /> cp /usr/libexec/ /var/www/usr/libexec/<br />
Update chpasswd configuration:
<br /> cd /var/www/etc<br /> vi chpasswd.conf<br /> vi ipauth<br />
Create squid passwd file for chpasswd to update in chroot jail
<br /> mkdir /var/www/etc/squid<br /> touch /var/www/etc/squid/passwd<br /> chown root:www /var/www/etc/squid/passwd<br /> chmod 660 /var/www/etc/squid/passwd<br />
Update/Modify the auth_param section of squid.conf to use new passwd file and basic authentication (must already have ncsa_auth in place and working)
<br /> vi /etc/squid/squid.conf<br /> <samp><br /> auth_param basic program /usr/local/squid/libexec/ncsa_auth /var/www/etc/squid/passwd<br /> auth_param basic children 5<br /> auth_param basic realm Home Localnet to Internet access<br /> auth_param basic credentialsttl 2 hours<br /> </samp><br />
Restart squid
<br /> squid -k reconfigure<br />
Your app should now be usable at http://<your.squidserver>/cgi-bin/chpasswd.cgi
