TCP Wrappers 7.6 and HP-UX 11.1

Hello Everyone,

I've recently installed TCP Wrappers 7.6 from the HP-UX portal site. The tcpd service appears to work but not fully. I cannot get any options from the /etc/hosts.allow file to work. Here's an example:

ftpd: ALL: BANNERS /etc/banners: SEVERITY
telnetd: ALL: BANNERS /etc/banners

Yes there is an ftpd file in /etc/banners. Permissions as permissable as possible. The inetd.conf file also has tcpd in the path for ftpd. I've used logger -p to verify syslog. The same hosts.allow file works on our Sun box. (in.ftpd of course) I've used all the tools: tcpdchk -v, tcpdmatch (<-- very useful but does not output the banner.) Any ideas? Am I missing something obvious??

Re: TCP Wrappers 7.6 and HP-UX 11.1

The following assumes that you downloaded TCP wrappers from or one of the mirrors. I think (but I might be wrong) that support for keyword "banners" may not be compiled in.

If you have a look at the source code package Makefile at
, you will find that optional features are not enabled.

#STYLE = -DPROCESS_OPTIONS # Enable language extensions.

So you can get the source code package from, uncomment the STYLE line from Makefile and recompile the package.

Alternative is to get TCP Wrappers from HP software web site. It seems to have optional features compiled in (but I haven't verified this).
