Analyze local pcap/pcapng captures to diagnose network transfer problems.
Use when given a pcap file to explain slow network transfer, connection
issues, abrupt TCP session termination, security association setup error,
private network tunnel establishment problem, DNS, TLS or encrypted
session establishment error, MTU or oversized packet drop, or receiver
buffer exhaustion. Read-only; no credentials required.
Triggers: "pcap analysis", "packet capture analysis", "analyze pcap file",
"slow network transfer", "TCP retransmission", "connection reset",
"IPsec/IKE negotiation failed", "VPN negotiation failure",
"TLS handshake failed", "DNS resolution failure", "MTU issue",
"zero window", "abrupt TCP session termination",
"domain name lookup error", "encrypted session establishment error",
"oversized packet drop".
