OK. I have bodged up the IPInterception.cc file and add the line from /usr/include/sys/types.h to get it to compile. Mu change to add the error string has resulted in the error coming out as: clientNatLookup: NAT lookup failed: ioctl(SIOCGNATL): (22) Invalid argument I think we have a smoking gun here! It is starting to look like Squid is constructing the structure wrong that it is passing to the ipnat driver via the ioctl. How do debug this is the question... Thanks for the help so far.. I'll post my findings if I get a solution. --------------- Barry Dean Networks Team -----Original Message----- From: Amos Jeffries [mailto:squid3@xxxxxxxxxxxxx] Sent: 15 August 2008 14:49 To: Dean, Barry Cc: squid-users@xxxxxxxxxxxxxxx Subject: Re: 2 Problems Dean, Barry wrote: > Hi, > > My setup: Sun X4200 Server 8GB RAM, Sun IPF 4.1.9 (592), Solaris 10 x86 Generic_137112-02 > > Problem 1: > > I compiled SQUID 3.0_STABLE5 no problem on Solaris 10 Generic_120012-14.

This is when I decided to alter IPInterception.cc so that the value of errno was included in the error message, and when I discovered it no longer compiled, refer to Problem 1 !!! > > Can anyone help me on this one... It sounds like the compiler and libraries need to be updated to match the new patched kernel. Amos -- Please use Squid 2.7.STABLE3 or 3.0.STABLE8
