Hi all, I went through an apparently normal build and install using the instructions in http://incubator.apache.org/couchdb/docs/installation.html . This is on Debian etch. Once installed I run $ sudo -u couchdb couchdb and get couch 0.7.3a652071 (LogLevel=debug) Apache CouchDB is starting. Apache CouchDB has started. Time to relax. [debug] [<0.1.0>] Config Info /usr/local/etc/couchdb/couch.ini: CurrentWorkingDir=/home/arved/development/couchdb DbRootDir=/usr/local/var/lib/couchdb BindAddress="127.0.0.1" Port="5984" DocumentRoot=/usr/local/share/couchdb/www LogFile=/usr/local/var/log/couchdb/couch.log UtilDriverDir=/usr/local/lib/couchdb/erlang/lib/couch-0.7.3a652071/priv/lib DbUpdateNotificationProcesses= FullTextSearchQueryServer= text/javascript=/usr/local/bin/couchjs /usr/local/share/couchdb/server/main.js Finally, when trying http://localhost:5984/_utils/index.html , I get [error] [<0.53.0>] {error_report,<0.21.0>, {<0.53.0>, crash_report, [[{pid,<0.53.0>}, {registered_name,[]}, {error_info,{undef,[{string,to_lower,["Host"]}, {mochiweb_headers,insert,3}, {lists,foldl,3}, {mochiweb,new_request,1}, {mochiweb_http,headers,4}, {proc_lib,init_p,5}]}}, {initial_call,{mochiweb_socket_server, acceptor_loop, [{<0.52.0>, #Port<0.122>, #Fun}]}}, {ancestors,[couch_httpd,couch_server_sup,<0.1.0>]}, {messages,[]}, {links,[<0.52.0>,#Port<0.126>]}, {dictionary,[]}, {trap_exit,false}, {status,running}, {heap_size,1597}, {stack_size,21}, {reductions,504}], []]}} [error] [<0.52.0>] {error_report,<0.21.0>, {<0.52.0>, std_error, {mochiweb_socket_server, 221, {child_error,{undef, [{string,to_lower,["Host"]}, {mochiweb_headers,insert,3}, {lists,foldl,3}, {mochiweb,new_request,1}, {mochiweb_http,headers,4}, {proc_lib,init_p,5}]}}}}} =ERROR REPORT==== 30-Apr-2008::07:53:43 === {mochiweb_socket_server,221, {child_error,{undef, [{string,to_lower,["Host"]}, {mochiweb_headers,insert,3}, {lists,foldl,3}, {mochiweb,new_request,1}, {mochiweb_http,headers,4}, {proc_lib,init_p,5}]}}} I did plenty of Google searching, looking for information on couch.ini, and *anything* useful on Mochiweb, and also looked at the CouchDB wiki (Troubleshooting and so forth). As near as I can tell a complaint is being made by something somewhere that the Host request header is undefined, but I sure don't know where to take it from there. Guidance appreciated. AHS
