Re: [Dorset] Message to Ralph: What was that command you used?
Hi Terry, At the meeting last night you used a command to discover the IP address of your domain. Â Paul just asked me what it was, but all I could remember was that it was a TLA something like git, (but not git). It was dig(1); domain information groper. Here's some examples to send onto Paul. $ dig google.com ; DiG 9.4.2-P2.1 google.com ;; global options: printcmd ;; Got answer: ;; -HEADER- opcode: QUERY, status: NOERROR, id: 29412 ;; flags: qr rd ra; QUERY: 1, ANSWER: 5, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;google.com.IN A ;; ANSWER SECTION: google.com. 161 IN A 74.125.230.80 google.com. 161 IN A 74.125.230.82 google.com. 161 IN A 74.125.230.84 google.com. 161 IN A 74.125.230.81 google.com. 161 IN A 74.125.230.83 ;; Query time: 0 msec ;; SERVER: 127.0.0.1#53(127.0.0.1) ;; WHEN: Wed Jan 12 08:50:00 2011 ;; MSG SIZE rcvd: 108 $ $ dig +short google.com # More terse. 74.125.230.83 74.125.230.80 74.125.230.82 74.125.230.84 74.125.230.81 $ $ dig +short google.com mx # Want MX records instead of default A. 400 google.com.s9b2.psmtp.com. 100 google.com.s9a1.psmtp.com. 300 google.com.s9b1.psmtp.com. 200 google.com.s9a2.psmtp.com. $ $ dig +short google.com soa ns1.google.com. dns-admin.google.com. 1438691 7200 1800 1209600 300 $ $ dig +multiline google.com soa # Explain SOA numbers. ; DiG 9.4.2-P2.1 +multiline google.com soa ;; global options: printcmd ;; Got answer: ;; -HEADER- opcode: QUERY, status: NOERROR, id: 58553 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;google.com.IN SOA ;; ANSWER SECTION: google.com. 57 IN SOA ns1.google.com. dns-admin.google.com.

[Dorset] Next Meeting; Tuesday?
Hi, Tim Waugh pointed out on #dorset that http://dorset.lug.org.uk/wiki/doku.php?id=meetings:pub says TimeTownVenue Tuesday 2011-02-02 20:00Bournemouth The Broadway but 2011-02-02 is a Wednesday. Oops. Have we settled on all meetings being on a Tuesday now? IOW, Bournemouth meetings are moving from Wednesday to Tuesday? I'll assume so unless you speak up in reply and will change the meeting date to 2011-02-01; if you've already put an entry in your diary it needs moving!

[Dorset] Sending Email through talktalk from Abroad.
Hi Clive, Regarding being able to send emails through talktalk's SMTP server from a non-talktalk IP address, e.g. abroad, you're not the first person to want to know. http://www.talktalkmembers.com/forums/showthread.php?t=7616 He doesn't get a straight answer unfortunately and I've been unable to find one either. You could contact talktalk direct to find out; I couldn't register on those forums as they want phone and account numbers else I'd ask on http://www.talktalkmembers.com/forums/forumdisplay.php?f=98 Anything Else This section of the support forum is for any other support related question you may have that doesn't fit into one of the above sections such as email and webspace issues. You're after http://en.wikipedia.org/wiki/SMTP_Authentication Anyone else on the list know about talktalk? You could attempt to query talktalk's SMTP server to see if it says it supports it. After installing package `netcat', something like printf 'ehlo example.com\nquit\n' | nc -i 2 smtp.talktalk.net 25 Example output for a non-TT one. It's the 250 lines that are interesting. $ printf 'ehlo example.com\nquit\n' | nc -i 2 relay.pair.com 2525 220 relay02.pair.com ESMTP 250-relay02.pair.com 250-PIPELINING 250 8BITMIME 221 relay02.pair.com $ Cheers, Ralph. -- Next meeting: Bournemouth, Tue or Wed 2011-02-?? 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ How to Report Bugs Effectively: http://goo.gl/4Xue
Re: [Dorset] Sending Email through talktalk from Abroad.
Hi Tim, Even if if supports authentication, I'd doubt very much that they'd allow access through a non-talktalk line - that's pretty standard practice to prevent use as a spam relay. Ah, is it? I thought auth., or at least secure auth. where credentials aren't passed as plain text, wsa there to permit this kind of thing. You're right, it does seem many ISPs don't provide it though. I see plus.net does, but then I'm found them to be a bit better than average in the past. http://community.plus.net/library/email/testing-smtp-authentication-using-telnet/ I have the same requirement and set up a home machine to be an authenticated SMTP relay over TLS. This then forwards to the ISP smarthost. It's quite simple to set up in Exim4 - if you want I can put my notes up on the Wiki. You'd obviously need to keep your home machine on 24/7 - ideal for one of those netbricks. Clive was thinking of a netbrick like a Sheevaplug for another purpose so this would be a solution for him too. Clive, you'd configure your Thunderbirds to send the email to your netbrick, whether you were home or away, and it, with its talktalk IP address, would then send it onto TT as happens from T'bird now. You mentioned TT's offer may be up soon. If you're thinking of switching ISP it may be worth seeing if they offer authenticated SMTP for when you're out and about.

How about Bournemouth Tuesday, as it is the non-kareoke quiet night, hopefully. Blandford Forum Wednesday, as they always seem to be nice and reservedly quiet. IOW, swap. Brickbats please, or forever hold your piece.

It's quite simple to set up in Exim4 - if you want I can put my notes up on the Wiki. You'd obviously need to keep your home machine on 24/7 - ideal for one of those netbricks. I tend to run at least one machine at home that's on 24/7 and that listens for ssh. That way I can tunnel smtp via my home machine using: ssh my.home.machine -L 2525:smtp.example.com:25 (Replace my.home.machine with the IP or DNS name of your home, and smtp.example.com with your ISP's SMTP server). This ssh command redirects all traffic to port 2525 on your local machine to port 25 on your ISP's mailserver, but via your home connection. I have an extra SMTP profile in Thunderbird that uses localhost:2525 as the SMTP server. I did (and still do) run a mailserver at home but find this method simpler and tend to use it more, as it only relies on opensshd. -- Next meeting: Bournemouth, Tue or Wed 2011-02-?? 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ How to Report Bugs Effectively: http://goo.gl/4Xue
