I'm using the same squid3.conf on 4 proxies with differenz hostnames. Back with 2.7 I didn't have to set visible_hostname explicitly. Squid would just use the hostname of the machine it was running on. With squid-3.0.STABLE19 all the error pages contain localhost instead of the machine's hostname: "Erzeugt am Thu, 06 May 2010 07:26:42 GMT von localhost (squid/3.0.STABLE19)" # hostname -a proxy-cvk-1 So what's wrong here? -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt@xxxxxxxxxx | http://www.charite.de
