>Description:
/sbin/ipfw on 2.2.6: variant treatment of port number:
failed expansion of '-' if uucp-path is first param, otherwise not
expanded & doesn't fail.
>How-To-Repeat:
/sbin/ipfw add pass log tcp from 193.174.4.84 uucp-path,uucp-rlogin to 193.174.4.10 out via isppp0
fails with
ipfw: unknown port ``path''
/sbin/ipfw add pass log tcp from 193.174.4.84 uucp,uucp-path,uucp-rlogin to 193.174.4.10 out via isppp0
works
>Fix:
Sorry, no C code patch, but I notice Julian Elsicher announced intention
to go do other ectension work to ipfw soon, so he may care to look at this.
(PS on that score , a syntax extension to support
via interface_a,interface_b
would be nice if you can be bothered to do it Julian E.
My temporary work around is to do:
$fwcmd add pass tcp from ${js_muc} uucp to ${uucp_muc} out via ${muc_if}
$fwcmd add pass log tcp from ${js_muc} uucp,uucp-path,uucp-rlogin to ${uucp_muc} out via ${muc_if}
Although I had originally wanted
$fwcmd add pass tcp from ${js_muc} uucp to ${uucp_muc} out via ${muc_if}
$fwcmd add pass log tcp from ${js_muc} uucp-path,uucp-rlogin to ${uucp_muc} out via ${muc_if}
