Specify Secure Remote Shell Command (DB2RSHCMD)

AltaNível 1Automatizadadb2

Descrição

The DB2RSHCMD registry varible specifies the remote shell command to use when starting remote database partitions and with the db2_all script to run utilities and commands on all database partitions. It is recommended that a value be used which encrypts the data sent between partitions, such as ssh. Passes when DB2RSHCMD is unset or points to ssh. Default: The default value is ssh. Run as the instance owner (or with sqllib/db2profile sourced) so the db2 CLP reads this instance's configuration.

Como é verificado

Método de auditoria: Comando shell

shell

out=$(db2set -all 2>/dev/null) || exit 1; printf '%s\n' "$out" | awk '/^\[[a-zA-Z]\]/ { l = $0; sub(/^\[[a-zA-Z]\] */, "", l); k = l; sub(/=.*/, "", k); v = l; sub(/^[^=]*=/, "", v); gsub(/[ \t]/, "", v); if (!(k in r)) r[k] = v } END { if (!("DB2RSHCMD" in r) || r["DB2RSHCMD"] ~ /(^|\/)ssh$/) print "compliant"; else print "noncompliant: " r["DB2RSHCMD"] }'

Saída esperada: compliant
