Configure connectionTimeout

FaibleNiveau 2Automatiséetomcat

Description

The connectionTimeout setting allows Tomcat to close idle sockets after a specific amount of time to save system resources. Every Connector must set connectionTimeout explicitly to 1-60000 ms (the benchmark example is 60000; tune lower for your load). Reads $CATALINA_BASE (default /opt/tomcat) and $CATALINA_HOME (default: $CATALINA_BASE); set them for packaged installs (e.g. CATALINA_BASE=/var/lib/tomcat10, CATALINA_HOME=/usr/share/tomcat10). XML comments are ignored.

Méthode de vérification

Méthode d'audit: Commande shell

shell

B=${CATALINA_BASE:-/opt/tomcat}; H=${CATALINA_HOME:-$B}; O=${TOMCAT_OWNER:-tomcat_admin}; G=${TOMCAT_GROUP:-tomcat}; x(){ [ -r "$1" ] || return 1; awk 'BEGIN{RS="<!--"} NR==1{print;next} {i=index($0,"-->"); if(i) print substr($0,i+3)}' "$1" | tr '\n\t\r' '   ' | tr '<' '\n'; }; s=$(x "$B/conf/server.xml") || exit 1; printf '%s\n' "$s" | awk 'function at(n,  r){if(match($0,"[[:space:]]" n "[[:space:]]*=[[:space:]]*[\"\047][^\"\047]*")){r=substr($0,RSTART,RLENGTH); sub(/^[^=]*=[[:space:]]*./,"",r); return r} return "-unset-"} /^Connector[[:space:]]/{v=at("connectionTimeout"); if(v=="-unset-" || v+0<1 || v+0>60000) bad=1} END{print bad?"noncompliant":"compliant"}'

Sortie attendue: compliant

Méthode de correction

Méthode de correction: Recommandation ou correctif d'infrastructure

Set connectionTimeout="60000" (or lower) on each <Connector> in server.xml. Restart Tomcat afterwards.
