The boring life of a Cisco router

Boring.
Life is boring.
THIS life is remarkably boring.

Spent yawning the usual heartbeats of a powered machine,
wasting electrical flows in few minimal life maintenance activities,
and
not
much
more.

A whole existence devoted to checking functional parameters,
handling a ridiculous number of packets,
without glimpses of action, stress, activity,
relations.

cisco 2610 (MPC860) processor (revision 0x203) with 28672K/4096K bytes of memory.

I have proud circuits, memory, interfaces, my Family is the biggest, broadest and most used, I mean...
Cisco Internetwork Operating System Software
IOS (tm) C2600 Software (C2600-I-M), Version 12.2(13), RELEASE SOFTWARE (fc1)

I boast remarkable features for exciting new e-services,
I was engineered to do much more than handling a bunch of silly headers.
Designed, engineered, programmed, reprogrammed, deployed, patched.

Yet,
I pass endless seconds handling the obvious,
such as checking an interface that seems connected to null.

00:02:38: Serial0/0(out): StEnq, myseq 15, yourseen 71, DTE up
00:02:38: datagramstart = 0x1C00854, datagramsize = 13
00:02:38: FR encap = 0xFCF10309
00:02:38: 00 75 01 01 01 03 02 0F 47
00:02:38:
00:02:38: Serial0/0(in): Status, myseq 15
00:02:38: RT IE 1, length 1, type 1
00:02:38: KA IE 3, length 2, yourseq 72, myseq 15

You might even find somehow exciting the overall feeling:
a WAN interface wired to a DTE,  the breeze of electronic trembles,
receiving signals, circuiting them to a microprocessor,
decoding, pipelining in internal buses, ticking the main processor awareness,
reassembling levels, building packets, controlling net flows.

There might be something interesting in these...
overwhelmingly
endlessly
definitively
b o r i n g
routine checks...

00:03:07: IP-Static:  0.0.0.0 0.0.0.0 Serial0/0.1 Path = 1, route table no change, recursive flag clear
00:03:07: IP-ST: if_list try 1
00:03:07: IP-ST: gw_list total 0, try 0, completed list TRUE
00:03:07: IP-Static: all_list, time elapsed 0 ms

Born to be a sad router.
Two interfaces, default functions, long idle times and some handling of sparse packets from a simple, silent internal network to the way outside here.
Not much else to do, just follow a damn, definitive, plain, dull
ip route 0.0.0.0 0.0.0.0 Serial0/0.1

Not even the thrills of dynamic routing,
not even few floating peers around,
some social activities,
a sight to the outside.

My view of endless hosts stops at my only peer to the real world.
I don't even know its name,
no cdp enable
I probably hate it.

I feel so... alone

00:03:08: Serial0/0(out): StEnq, myseq 18, yourseen 74, DTE up
00:03:08: datagramstart = 0x1D58954, datagramsize = 13

00:03:08: PVC IE 0x7 , length 0x6 , dlci 160, status 0x2 , bw 102400

You see?
I'm not alone.
Every ten seconds of your existence.
Every ten seconds exchange link awareness with a box talking languages of inferior levels.

One of the few ciclying checks of a wasted life,
interrupted at times by the feeble network activity of ... it doesn't even has a name... IT/HE/SHE...

**:**:**: IP ARP: rcvd req src 192.168.0.10 00e0.4c59.4107, dst 192.168.0.1 Ethernet0/0
**:**:**: IP ARP: sent rep src 192.168.0.1 0004.9ac2.4400, dst 192.168.0.103 00e0.4c59.4107 Ethernet0/0

It just has that immutable address: 192.168.0.10

My only, unique, lazy served host,
that at times decides to do something more than arp handshakes,
and, in a yawning outburst of Internet awareness,
handles me few packets to route, once a day,
always to the same destination,
always at the same hour,
outside.

gw uptime is 2 years, 3 weeks, 4 days, 22 hours, 12 minutes
Guess what? Yet Another Poetic Licence (...Mistake?) Find it and win nothing.

Oh,
let me introduce myself, my name is gw,
honest, simple, effective, exotic name,
with its sad destiny.

I'm handling this existence for two years,
serving a single, idle host,
a single nat entry,
and its sparse packets.

I mean,
could
you
handle
THIS?

Two whole years passed doing... nothing

What a waste of Computing Resources.
What a pity, a disaster, a disgrace,
an enormous piece of shit.
What a damn, unbearable en...

What a bunch of funny packets.
Welcome, welcome, I've lot of free time for you.
Wonder what you want, you look strange, after all.

What's this?
Something weird happening outside there?
Never seen such a traffic from the outside.

Ehi strangers!
Nothing to do here!
Closed for holidays, I've been busy lately,
have to rest, have a date, sorry no time for ...

What RFCs have you read?

What's the point?
What's the problem with you?
Keep off! Beware!
I've got reactive protections,
I can analyze, investigate, counterstrike,
I can firewall you all out of here,
I can... I could...
If just I were configured in a sane way.

Silence.

Finally silence.

Was it ...
An outburst of network assault?
The frantic dance of evil sources?
An attempt to Deny Consciousness?

Silence.

Overloaded in an idle state of exhausted inactivity.

Input queue: 76/75/68/0 (size/max/drops/flushes); Total output drops: 0

I feel like my interfaces are filled by concrete,
obscured by weighty mass,
driven to exhaustion.

I really need a vacation,
some rest, maybe a reload.
Buffers are full,
no more packets to handle...

Full queues and blocked interfaces.
An evirated router.

Anybody out there?

Is ...
there ...
Any ....
... body ?
