Umm... if you can get into your home mail server via SSH, why can't you send email from there using plain old 'mail' command? Or do you have something similar to what I have, which is my own domain, which gets my email and then dumps it into my ISP's email system for pulling down? In that case, using my ISP's outgoing email servers was problematic, because they didn't like me using my @stoffel.org domain email address on outgoing email. Or at least they didn't like it much, and people further downstream started dropping/bouncing my emails thinking I was a spammer. So now I have postfix at home setup to use SMTPS to send all outgoing email via my domain's ISP's mail server, encrypted and all is good again. But basically, can you explain your setup in more detail please? It's not clear where the bottleneck really is. Richard> What are my options?

Which as we get more and more mobile in our professional lives, isn't a good idea in my mind any more. Heck, I'm reading this from work, but I'm ssh'd into my home system and all the processing and such is happening within a 'screen' session using Emacs and the mail reader 'vm'. All text based, and quick and easy to write/read/edit emails.

Why is the web the answer to all questions now? *grin* And of course you would make sure to only allow HTTPS connections to your squirrelmail web mail server running on your home machine, right? Good luck! John

Oh, in that case, simply explain to her that you couldn't reply to her because your IMAP MUA wasn't properly setup to tunnel SMTP traffic via SSH and all your attempts were just ending up in /dev/null! Hiding information is not a healthy start to a new relationship you know... ;-)

I've been doing that occasionally, but I don't want much personal mail going through their servers, and (pardon me if this is too much information) I want to reply to a girl's email via match.com, but match.com expects my emails to come from match(a)richardklein.org, and I think my emails end up in /dev/null if they come from some other address. Obviously, I'd prefer to reply to her from home, but I haven't been home much to even sit down at the computer lately. -- Rich

Mail problem for a Monday morning

by Klein, Richard

It's Monday morning, I'm tired, and I've got a headache, so I'm not sure I can even explain the problem right now, let alone solve it. Work seems to block port 25 (SMTP), but not 993 (IMAP-S) or 22 (SSH), so I can SSH into my (home) mail server, or read my mail via IMAP, but I can't send anything. My (home) email account doesn't have a shell account, so I can't log-in via SSH and send email in pine or something (and that would be a PITA, anyway). What are my options? Can I use putty to tunnel SMTP through port 22 SSH? One of these days I'll set up webmail and this will be a moot point, but I'm hoping for a quicker, more immediate solution. -- Thanks, Rich

Re: [Wlug] Image/Backup tools

by Eric Stein

There are many applications for doing backups, most of which have strong and weak points. I use 3 systems: * Homemade shell script that tgzs the entire backup set into a dated file, encrypts it with gpg, and transfers it to the backup server. o Strong points 1. Secure - no need to trust foreign server 2. High redundancy of data o Weak points 1. Bandwidth intensive (only good for small data sets) 2. Heavy on CPU usage 3. Uses a lot of disk space * Rsync o Strong points 1. Space efficient on the backup server 2. Bandwidth efficient 3. Fast o Weak points 1. No revisions; undetected data loss will be propagated to the backup server * rdiff-backup o Strong points 1. Bandwidth efficient 2. Has revisions and stores diffs compressed 3. Somewhat space efficient because of the compressed diffs o Weak points 1. Uses more space on the backup server than Rsync I use Rsync for mirroring my less important data, and rdiff-backup for my important files. All of these methods can be scheduled with cron.

Image/Backup tools

by Michael Zarozinski

Hi all, I'm looking for recommendations for backup/imaging tools. We have 2 servers runing RHEL4, one is a production server and the other a development server. We were recently hit with a DOS attack and possibly a root kit attack. It's been a long task re-installing all the software/tweaks we've made so I'm looking for something to ease this process if it happens in the future. Thanks in advance, Michael Z
