The terminal splits a line as Java's window does and runs ls, cd, pwd,
mkdir, touch, cp, mv, rm, cat, test, help, ipconfig and route on the
node's files, which are the project's own. Its texts are generated from
the bundle Java loads. TerminalCases feeds Java's Terminal without a
network (16 cases, de and en); eight cases name Java bugs.

The program sends to its account's SMTP server, one connection for each
recipient, and fetches its mails by POP3; the server now sends mails on
to other domains by MX and returns notices to their senders. The
program's folders are in the snapshot and go back into the project.
EmailClientRun plays six stories with two servers; the mail oracles run
in the language's locale, so Java's notice dates match the core's.

SMTP on port 25 stores mails for the domain's accounts as Java reads
them anew and tells a local sender of unknown recipients; POP3 on port
110 hands them out. The mailboxes are in the snapshot and go back into
the project. EmailRun plays four stories over the network; MailCases
feeds Java's workers without one (26 cases, de and en). 18 cases name
Java bugs that the core does not take.

Routers and home routers start a web server on port 80 with Java's index,
log and routes pages in the project's language (routerPages.ts); the
firewall keeps a log per node that outlives a new start; RIP routes carry
the telling router's public address. TCP counts sequence numbers and
segments in Java's characters, not bytes. RouterWebRun records six stories,
with firewalls now built by ScenarioNetwork. Not taken from Java: its router
server sometimes never listening (a race in setAktiv), and </titel>.

The servers share ServerAnwendung's frame (server.ts); the web server serves
/webserver with virtual hosts, the browser loads a page and its images over
one connection to port 80 (web.ts); HTTP in Java's text form (http.ts).
WebRun records eleven stories on the new web-lan network, with the server's
files; webJava.test.ts plays them card by card. A program's close is a
request, as Java's schliessen. Not taken from Java: /../ serving any file of
the host; an unreadable request closing the connection without a word.

Programs run as generators that yield what they wait for (threads.ts); the
engine resumes them after every event. TCP connect, send, receive, accept
and name resolution exist as such steps; the blocking calls wrap them.
EchoRun records eight stories in Java FILIUS, frames, tables and each
program's window lines; echoJava.test.ts plays them card by card. Not
taken from Java: a connection without a route hangs for ever; a server
switched off leaves its connections' last FIN unanswered.

ExampleRun opens an example as FILIUS opens it (SzenarioVerwaltung.laden
into the window's lists), starts it as the action mode does, plays a
story and writes every card's frames and tables, the calls, the
addresses and the RIP tables' changes. examplesJava.test.ts reads the
same file with this package's reader and runs it in the core
(projectSnapshot, new): routing (internetwork_komplett), DHCP
(einfaches_rechnernetz_komplett), DNS (dns_server), NAT
(nat_with_mapped_port) and firewall (Internet_Komplett_..._DE) match
card by card.
Found and fixed: a host's ipForwardingEnabled, which Java saves and
obeys, was unknown to the reader, the model, the core, the writer, the
export and FlsOracle; and Java's ARP learns only from a request for its
own address or a reply. Named Java bugs: a ping without a gateway throws
a NullPointerException; a home router drops the answer of a second
remote end. Open: Java picks between equally long RIP routes by thread
timing.

The core translates before the IP thread, as Java's NAT threads sit
between card and Ethernet: out, the WAN address and the entry's port (ICMP
keeps its identifier); in, by remote end, port and protocol, else by the
port forwarding, which then makes a dynamic entry; a ping at the WAN
address is answered by the router, packets from outside for the LAN are
dropped, both sides pass the router's firewall, TTL 1 going out gets time
exceeded. Dynamic entries expire at Java's check each second, 300 s times
the delay factor old (55 minutes at 90 %), refreshed only by what comes in.
The home router forwards as a router does.
Measured and not taken: when a LAN endpoint sends to a second remote end,
Java gives it the entry's WAN port but no entry, and the answer stays at
the router; the core adds an entry for each new remote end on that port.
The oracle now records every card of a node (the second card of routers
was missing); the ARP and RIP runs are recorded anew and still match.

DNS follows Java's DNSServer and Resolver, not Swift's typed format:
Java's text messages (dns.ts), a server on port 53 answering from its
records (no question in the answer, RCODE 0, a referral with NS and A in
the answer section), an iterative resolver that waits five round trips per
query and remembers only the servers it was referred to. Recursion throws
NotPortedError until the next step. The snapshot carries the DNS servers
switched on. receiveUdp returns as soon as a datagram is there, as Java's
empfangen does.
dnsJava.test.ts compares DnsRun's five lookups; four match frame by frame,
the missing server waits for Java's ARP (named as not yet like Java).

engine.ts ports Swift's "DHCP server and automatic client": an active
server listens on port 67 from the start and offers a static assignment
before its range, round from the address after the last one offered;
offers last 10 s, dynamic leases a day, and a server whose offer another
server beat blacklists that address for a while. A client starts as an
event: DISCOVER, OFFER, a check by ARP, DECLINE, REQUEST, ACK or NAK,
2.5 s per wait, and after ten failures its old address back. The snapshot
carries the DHCP settings of clients and servers.
Four scenarios match the Swift engine. One Swift error is named in the
oracle test: a client run directly is advanced a second time, to FINISH,
by the server's answer within its own DISCOVER, and the outer run then
writes back its stale copy of the status (Swift's value types); the
address and every trace agree, only the reported status is wrong in
Swift. Swift's three DHCP engine tests are ported, with tests for
stopping and the message format. 15 mutation probes, 14 caught; the other
concerns the home router, which runs only once NAT is ported.
Two departures from Java remain, to be fixed next: from the event queue
the client's ARP check does not wait, so an address conflict is never
found, and each answer that wakes the client makes it send its state's
message again (a second DISCOVER and REQUEST, the second answered with
NAK). Java waits a round trip and sends once per attempt.

First slice of the TypeScript port of the filius-ipad runtime engine,
with 29 tests ported from the Swift suite. Parts not ported yet throw
NotPortedError instead of guessing.
