Cable modem poops out on me

Post by Jacob Oos » Thu, 10 Mar 2005 11:42:29



I haven't installed any new hardware or done any system fiddling to
account for this, but my cable modem has been going slower and slower
for the past month or so, taking a really long time to connect to mail,
news, and web servers.  Sometimes it even times out from taking so long.
  What the heck is going on?  I haven't kicked my computer or installed
anything new, it used to run just fine and when I booted to my Windows
partition (which I haven't done in a long time) to test out the speed
there, it ran as fast as ever.

What makes you think it's the cable modem, as opposed to your own
system?

Why didn't you give any information that might help debug your
problem?

It's a FGA (Frequently Given Answer) but you should read "How to Ask
Questions The Smart Way" by Eric Raymond.

I didn't mean to imply that it was my modem per se, I guess I could have
said "broadband poops out on me."

Well, I didn't want to provide a bunch of unnecessary information, so I
figured that whoever might be able to help me would prompt me for what
was necessary.  I'm not a networking expert.

Windoze blazes across the internet you say, while your *nix partition
crawls along?  My guess.. and of course it could be many things... Is
your box has been rooted.  By that i mean, someone may be using your
box as a jump point, or they are just using your bandwidth to FXP (ftp
server to ftp server) information from higher speed connection rooted
boxes. Either way, the only thing you'd probably notice if you were
unaware of such events is slower network speeds.... I would check what
users are running procs on the box (ps aux) , and also check to see
what your "netstat" returns as.. The entries which are important are
those with the heading tcp... Another key... And this is simple... Look
at those status lights on your router/cable modem. if they are flashing
outa control and your not doing a damn thing... chances are someone
else is... Remotely. My 2

Good glaven, I thought Linux was supposed to be more secure than XP!
When I enter "ps aux" I see mostly "root" and "jacob" (that's me).  I
also see a few things under the users xfs, 72, daemon, and rpc.  I only
have my root account and my personal account on my machine, so I take it
these are the rogue users hacking my system?

I see about ten under "tcp," I don't really know what they mean but I
see one for amazon.com, a web page I hardly ever go to.

I've noticed that too.  Thanks for your help, what can I do to stop this?

Nope, they're system users automatically created by the installation
of various programs.  Or crackers, no way to tell since you persist
in not giving any useful information.

"Linux" is highly insecure, and XP with Service Pack 2 is quite
secure.  Now, a modern and well-done Linux distribution (say, Debian
or SuSE) set up and administered by a competent person (say, me) is
fairly secure, but for an inexperienced administrator you're actually
far more secure with Windows.

Did it even occur to you to post the actual results of netstat and
ps?  Actually if a process is connecting to a site without your
permission that's a very bad sign.

If you want to be sure you're cracked, run programs like chkrootkit
or Rootkit Hunter, which check for known penetration techniques.  To
be really safe, take your system off the network, repartition and
reformat the hard disk, and install a new operating system. (You can
back up all your actual data to a CD or something, just don't save
any programs.) The whole reinstallation process can take less than
two hours if you do it right.  I strongly suggest either switching to
a less administration-intensive operating system, or at least reading
up on Linux before installing.

If you're a Linux beginner and don't want to go back to Windows, may
I suggest Ubuntu Linux?  It's not the most hand-holding distribution,
but a very simple command ("aptitude update && aptitude upgrade") can
install every security fix known to the developers in a matter of
minutes, and being a Debian-derived distro it's very quick on the
update.

The only person I've heard make that claim, is Steve Ballmer.  Why do you
consider Linux insecure, when so many in the industry say otherwise?  I'm
not talking about people who do dumb things, like run telnet over the
internet etc.

Because most distributions are insecure as shipped and most newbies
don't know how to secure them.  Also, most people don't regularly
update their systems as exploits are discovered.

A *properly administered* Linux system can be extremely secure.  It's
just that it's much easier to secure an XP box.

I didn't know how much info would be wanted on this newsgroup.  On some
groups people complain about long posts.  Here's what I get with ps aux:

Insecure in what ways?

Automatic installation of insecure servers (e.g. obsolete version of
Sendmail or Bind) to name the most obvious.

Why did you substitute non-ASCII characters for some but not all of
my spaces?

Are you running a web server of some sort, say Apache?

Mandrake's ps is acting differently from Debian's, so I'm not sure if
those are outgoing or incoming connections.

Are you running a name server (DNS)?

Rootkits are quite old.  It isn't one thing, it's a generic term used
by the crackers to mean "a program that gets you root."

Mandrake is also fine.

I see no reason right now to think you're 0wned, actually, except
those various server connections I quoted.  

You might try a network traffic monitor like vnstat to see what's
generating all the traffic.  

Do you work behind NAT (what manufacturers tend to call a "firewall")
or is your machine directly on the Internet?

I didn't.  I simply marked your text and hit reply.

Running an NNTP server?  On port 32783?  Looks to me like he has an
established connection _to_ an NNTP server.  I'm willing to bet he was
logged into an NNTP server when he ran netstat.

Quote:> Are you running a web server of some sort, say Apache?

Again, these appear to be locally originating connections.

His ps aux looks just like my(gentoo) ps aux, and neither display network
connection information.  Perhaps Debian merged netstat with ps while I
wasn't looking.

Quote:> Are you running a name server (DNS)?

Again, these appear to be locally originating connections.

More information about the overall network setup is required.  Routers,
hubs, switches, firewalls, etc.  It's always a drastic leap to go from my
connection is slow, to you've been '0wned'.

Network cables are known to 'go bad', hub/switch ports are known to 'go
bad', etc, etc...

1. Modem cable pin-outs

Hi,

We have a Bull Escala server which has three DB-9 male serial sockets on the
rear of it.

I need to connect a hayes compatible modem, to allow dial-in access. The
modem has a DB-25 female socket at the rear.

Can anyone supply me with a pin-out diagram for a:

DB-9 pin female to DB-25 pin male cable.

I've check the AIX web support documents, but they only refer to 10 and 25
pin serial sockets at the server end.

Cheers,

James G.
