Charter Telephone reviews, boylston?
by John Stoffel
Hi,
Anyone on here using Charter Telephone VOIP service? I've currently
got Verizon, but the wife hates it because our phone lines get flaky
all the time, esp when it rains.
So I'm thinking to save money and combine all my stuff onto Charter.
I've already got High Speed internet and regular old cable. Not wild
about Digital Cable since I'm happy with Tivo and I don't want yet
another set top box to have to deal with...
So, any horror stories about Charter Phone VOIP quality and service?
Thanks,
John

Wireless mesh network question
by Andy Stewart
HI guys,
I am planning to setup a wireless mesh network at a ham radio event in June.
Each mesh node will consist of two Linksys WRT54GLs, much like the demo
I showed at a recent WLUG meeting.
One of the WRT54GLs will be on channel 6 and carry mesh network traffic.
The other one will be on channel 1 and allow generic wifi devices
access to the mesh network.
It seems like there would be an interference problem if every node
allowed wifi access on channel 1. Should this be 4 different wifi
channels? It is possible for a user to be within radio range of
multiple of them simultaneously.
Thoughts? I've never setup a wireless network before and could use your
advice. These mesh nodes will be placed outside in weatherproof
enclosures with battery power.
Thanks!
Andy

sshd_config MaxStartups
by Jamie Guinan
Hi Group!
I'm seeking opinions about an sshd feature.
I was doing some work on a remote system (I did not set it up) that
seemed to be refusing ssh and scp connections randomly.
I looked into it, and finally stumbled across this from sshd_config(5),
MaxStartups
Specifies the maximum number of concurrent unauthenticated connections to the SSH daemon.
Additional connections will be dropped until authentication succeeds or the LoginGraceTime
expires for a connection. The default is 10.
Alternatively, random early drop can be enabled by specifying the three colon separated val‐
ues “start:rate:full” (e.g. "10:30:60"). sshd(8) will refuse connection attempts with a
probability of “rate/100” (30%) if there are currently “start” (10) unauthenticated connec‐
tions. The probability increases linearly and all connection attempts are refused if the
number of unauthenticated connections reaches “full” (60).
Indeed, the server had this setting,
MaxStartups 10:50:20
This just seems like a terrible option. You can DOS their server just
by making 20 connections and leaving them hanging. And it breaks any
automated scripts relying on ssh or scp (unless you wrap them in a
loop until they succeed, ugh).
My guess is that the reasoning behind this feature that it will filter
out a number of automated attacks. That seems no better than
security-by-obscurity, and I know how some of you feel about that. :)
Can you think of any sane reason to enable this feature, or for it to
even exist at all?
Best regards,
-Jamie

linux networking question (reformatted for readability)
by Brad
(i appologize for the previous message that i completely unreadable.)
Dear W-LUGgers,
I had some strange network related behavior that left me baffled and i wanted
to hear some theories from more experienced network admins.
The network layout is the following. The network is pretty simple, external
traffic passes through a bridged-firewall (OpenBSD, my choice) into an OS X
server (not my choice) which handles NAT/DHCP/DNS et al., and all the office
computers are dhcp clients to the OS X server. The trouble machines are linux
(ubuntu) desktop clients.
The scenario is the following. I was doing work on the bridged firewall
(OpenBSD) and somehow caused it to kernel panic, oopsie! So the
bridged-firewall went down thus no-one had internet access, Dou! i quickly
bounced the machine. It came back on-line and clients were able to access the
internet, huzzah! But, the strange behavior was in two linux machines within
the network that were not able to access some external IPs. My linux desktop
could not access 8.8.8.8, when pinging, i could see an arp who-has request
originating from my machine, i could see the packet come into the OS X server.
But the request always went unanswered. The same behavior happened to another
linux desktop but with 192.48.178.134 (sgi.com). My desktop could ping sgi.com.
So each linux desktop had *different* unreachable IPs. The rest of the internet
was reachable. I tried clearing the arp-cache on the OS X server, then clearing
the NAT state tables, then I rebooted the OS X server, none solved the problem.
I finally renewed the dhcp lease on my linux desktop machine and that allowed
the ping to complete.
What would case this behavior? Could it be stale arp-cache on the linux
machine? ( I *should* have tried to clear the arp-cache on the linux machine
before i renewed the dhcp lease, but i didn’t think of that until after the
fact.) The linux machine was sending out arp who-has requests so would a stale
cache even matter? Why would no one answer the arp requests? I am not an expert
network admin (its just a side job since the company is only 15 people). I
don’t expect to get a resolution but i’m interested to hear any theories.
Thanks and cheers, — brad
PS. As a worcester transplant to boston, i am really jealous i don’t live
closer to attend meetings. The topics of late sound outstanding.
