It does appear to be a dns problem after all. After renaming resolv.conf to resolv.conf.bak the problem is cured, although only hosts in the hosts file can be looked up. The strange thing is that both the 'nslookup' & 'host' commands both appeared to retrieve the correct information from the dns server (for both forward and reverse lookups) on our network. The dns server could be a tad broken at it is running RedHat Linux. Another strange thing I discovered was that 'telnet localhost' caused nameserver queries, even though host.conf has the default 'hosts' then 'bind' order. This 'telnet localhost' took 75 seconds to even connect, all this when 'nslookup localhost' & 'nslookup 127.0.0.1' work fine. Oh well, ...
