Re: [Wlug] mail disaster recovery

by Richard Goodman

Karl, That was exactly what I was looking for. Did the local-host-names changes; I already had the RELAY lines in access on the backup machine. Since the primary DNS is on the down IP address, I modified the secondary (slave) DNS which is one of my office boxes by adding a second MX line: my-host MX 99 temp.server.domain. <--dot at end and restarted that named. Its been quite a while and I'm not seeing any mail queueing, and I know there's mail that should be coming in on a regular basis. What else might I have missed? What can I use (nslookup, dig ? with what parameters) to see whether the MX lines are right? When I send a test email from an off-site machine, the sending sendmail log says "Connection timed out" and shows the down IP address.

Re: [Wlug] 1st posting: Worcester ISP? Distros? LAC?

by Gregory Avedissian

Hi Brian, I'm just an end user, still finding my way around after a couple years. My experience with a dialup account is that I've never had to talk to my ISP about linux. Setting up the account in SuSE 7.2 was easier than in win98. My experience with Debian 3.0 - The installer is archaic. First, you have to put in all four disks to be read. Then you get to select a base package, then you get to fill in more selections from a list of everything. You can use the arrow keys to scroll up and down the list of over a thousand packages and the space key to select them. If you pick something that has conflicts or dependencies, you jump to another screen and then somehow, if you do the right keystrokes, you get to the list of conflicts or dependencies, and then by some unknown keystrokes, you can get back to the main list. If you have the misfortune to hit the enter key during this process, the installation begins, and you have to wait until it's done to add in the rest of the packages. If you don't do it then, you'll have to scan in all four disks next time to add stuff. I did this a couple weeks ago, and I did manage to get a working installation. Setting up XFree went very smoothly (a new experience for me). It worked fine, but every time I booted up, it brought me to a graphical login screen for X, and I wasn't allowed to log in as root. So I logged in as user, hit ctrl-alt-F2 to get another login screen, and logged in as root. Tried to run a second X-session from root, but it wouldn't work. After two days of screwing around with trying to install what I wanted, I wiped it out and installed SuSE 7.2. It took me about an hour.

I have no first-hand experience with DSL, but I would expect it's shares a lot of characteristics (in terms of terms-of-services, reliability) with other residential services. There's usually no guarantee of stellar reliability, and many don't support (or allow) "servers". That's an important consideration if your mail is important to you. > I am willing to have a bit of trouble in order to learn how > it works, but is it common for DSL to "go down"? Why is that? Again, I don't use DSL, but I have had plenty of outages both here and back in Phoenix that have nothing to do with the unerlying technology. Your ISP can have routing problems to the rest of the world, their equipment or DNS servers can be misconfigured, and of course denial-of-service attacks can take their toll. Here, I've become much more familiar with power-related problems. Not "common" but certainly not business-class either. > [...] Losing my mail was fine, but the family went nuts when I > > was on the road and we had an outage. > > What's up with that? DSL or TV cable? Why outage? In the example I cited, it was HFC (cable). The reasons for the outage varied from power outages (my end and theirs), changes in service (it's residential -- they change it when they want i.e. sudden port blocking) and those mysterious 3 hour drops that I never could pin down exactly. > > I wound up moving my SMTP to a $2/mo. hosting plan that will queue > > mail for me until I poll using POP via fetchmail.

There are no doubt others, but I went with bmhost.com. It's nothing stellar if you're after hosting for a big website, but you get 10M storage and connectivity seems good. I poll it every 5 minutes via fetchmail and sort things out on my server. They're not particulary linux-aware though, but the servers are RedHat. You can get (chroot) ssh access. The important thing is I can survive an outage on my end without losing mail, and they offer webmail for those situations. Tell 'em I sent ya (ttlexceeded.com is the domain I host there) and we can probably pool to save a few bucks. I paid dyndns.org the $30 one-time fee for "custom" DNS, so I've got my DNS set up there, with dynamically updated entries for my home system (updated via the dhclient scripts), but nice, stable entries pointing at bmhost for MX and web addresses. The only thing I can't do is set up anti-UCE on my SMTP server though bmhost offers some, and they do provide anti-virus scanning standard, so I don't get the glamor of fighting those on my own... which I've found gives me a lot more free time. Of course, none of this applies if you're running a business on your home system. - Bob

I've had them at my current apartment for 1 1/2 years, and there were only two (very short) outages. They don't mind if you share your connection via wireless, you get static ip addresses, they don't block ports, let you run servers, etc. Very good ISP. -- Josh Huber

Hi all, Newbie here. I want to get to the command line and some interesting scripting projects as soon as possible. Would you help me get there? Some preliminaries: First, I live in Worcester.

I hear that RPM-based approaches give headaches in this regard.

There's no reason not to restart the WPILA, especially since it provides meeting space here on campus. I'm sure it will be closely tied to WLUG, of course.
