Hi Mark, hi list. Squid -v on squids-STABLE12 should be a clone of squid-STABLE10. Just, that i recompiled it with the same properties as you can see now. Just after turning off this STABLE12-machine our network relieves harmless again.... But anyway - i want to stay on actual security-prevention. My output of 'squid -v': Squid Cache: Version 2.5.STABLE12 configure options: --with-dl --enable-snmp --enable-carp --enable-useragent-log '--enable-auth=basic digest ntlm' '--enable-basic-auth-helpers=LDAP MSNT NCSA PAM SMB YP getpwnam multi-domain-NTLM' '--enable-ntlm-auth-helpers=SMB no_check' --enable-digest-auth-helpers=password '--enable-external-acl-helpers=ip_user ldap_group unix_group wbinfo_group' --enable-ntlm-fail-open --enable-referer-log --enable-arp-acl --enable-htcp --enable-underscores --enable-stacktraces --enable-delay-pools --enable-ssl --enable-cache-digests --enable-poll --enable-x-accelerator-vary Cheers andrew -----Ursprüngliche Nachricht----- Von: Mark Elsen [mailto:mark.elsen@xxxxxxxxx] Gesendet: Montag, 16.

In the STABLE12-case, what is the output of : % squid -v M.
