The problem with setting up a reliable server that you never have to mess with is you forget how you set it up. :) I set up a virtual mail domain, and the mail users of that domain don't have shell accounts, so I can't log in as one of those users at the SSH (shell) prompt. I thought that would be more secure, because I might want to give email accounts to friends who would have no need for a shell account. > 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.

Yeah, I thought about forging the from: header for certain emails, but I figured my employer's ISP would block that (it *should* block that, anyway). Plus, knowing me, I'd forget to change it back after I sent the email, and then I'd be sending out business emails with my personal email in the from: header. I don't think my company would appreciate that. > 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. I'm running Courier-IMAP and...I forget what else...at home. I added an account to Outlook at work to check my mail. It can receive mail fine, but sent messages just sit in the "outbox" forever. I tried telnetting into my server: port 143 gets me the IMAP prompts like you'd expect, but port 25 gets nothing, so I figure my employer is blocking port 25. That's not surprising. My mailserver runs richardklein.org as a virtual domain, and users @richardklein.org don't have shell accounts. If I SSH into my shell account it reports no mail because all my mail gets sent to the @richardklein.org user(s). > Richard> What are my options?

I greatly prefer IMAP to webmail, but yeah, if I ever get around to installing squirrelmail, it'll only accept HTTPS connections. -- Rich

Problems with a Sparc ULTRA1

by ken jones

I just acquired by second Sparc ULTRA1 Creator. It does not boot. After much struggle complaining about not finding sda4, it concludes: VSF: can not open root device "sda4" or 08:04 Please append a correct "root=" boot device Kernel panic: VFS: unable to mount root fs on 08:04 Press L1-a to return to the boot prom I've tried booting from my aurora 1.0 iso disk set. No luck. I've tried booting from my just out of the envelope GENTOO disk. No luck. Before it gives up it seems to have found the two scsi drives. It says: Attached scsi disk sda at scsi0, channel 0, id0, lun Attached scsi disk sdb at scsi0, channel 0, id1, lun It has found the following partitions partitions if that is what these are. /dev/scsi/host0/bus0/target0/lun0: p1 p2 p3 p4 and /dev/scsi/host0/bus0/target1/lun0: p1 p3 I stopped the boot: with a "stop a". ok test scsi > CE DMA fill from address ffee2000 for 80 bytes succeeded Dma register test -- succeeded Esp register test -- succeeded Dma read test -- succeeded Dma write test -- succeeded Any ideas?

programming help needed

by Mark Richards

With apologies to the list if this is inappropriate in which case please send me to a better forum.. Immediately seeking a person to help me with a large and complex php/MySql/javascript/html project. The work will initially involve fixing up maintenance front ends (and getting a few to work) and will move quickly into presentation-layer coding that clients will see. For our client side code we use the Smarty templating system which provides for a very clean connection between the html and the data. The maintenance front ends are hacked out with php as single-document scripts (one script presents a record and the same one edits and saves). Good to know http post. Most of our systems are working and the partially-documented code will probably be an easy read once I provide the overview and tutorial. Tasks will be fairly loosely spec'd in the beginning so some creativity is desired and encouraged. If you're really good (I hope so) tell me how to do it better. However there may be deferral of some improvements as we push to get it fully working. Very close communications as to how the task will be achieved will be essential to avoid duplication of efforts and synergy. Documenting code would be a plus. Skill levels need to be intermediate to expert in php. Knowing how to structure a query is good. Figuring out how to accomplish something on the client side in Javascript (we try not to use much) and achieving a consistent look with the smarty/html is also essential. If you don't know smarty, don't worry. It's really easy to work with and well documented. Are you artsy? I know what looks good but have no idea how to get there. Artsy is welcome and needed, but not a show-stopper. We have at least a solid part time need now. Work for the first few days with me for familiarity, then independently. SSH certificate for access. One server for testing and another going online shortly for production. Non disclosure and data security agreement required. We can supply workstation here but nice if you can work with your own over a good connection. As in my posting for a linux sysadmin, we need a methodical person who documents and who can teach (without pain). I never ask the same stupid question more than once (sadly, the second time I may, however, re-phrase it). I might, after searching through other resources, send an email: "how the heck can I do [a certain task] in html". You might shrug and utter an epitaph. We are in the solar energy field. No government work. All green and good. Future? I haven't the foggiest idea. But ours is a good place to learn about solar energy and technology applications. mark richards SolarWave mark-dot-richards-at-massmicro-dot-com

sysadmin needed

by Mark Richards

With apologies to the list if this is inappropriate in which case please send me to a better forum.. We are immediately seeking a person to do some ad-hoc (and a few hours per month? of routine) server maintenance for us with an initial push requiring more time for a new server setup and correction of problems on existing box. We have one dedicated in service and another coming on line next week. We're a small 2-person company and are very busy trying to bring a product to market with no/little time to devote to server maintenance. List of needed skills and software we are running (open to various levels of ability in each; to discuss): - linux, of course - CentOS (almost everything we have is repository based) - yum, cron, the basics - isp firewall but also iptables used on dedicated boxes - imap mail on current server with basic web services - apache, php, mysql - ssl, amavisd, spamassassin, dovecot, clamd. - large mysql database on new server with web services (no mail) Tasks: - routine check of both servers * security issues (we have snort installed and have plugins) * performance issues * specialized backups (other than daily by host) * review logs; identify issues; resolve - software install/setup * anything new or a manual update - existing issues * infrequent timeouts * some log entries for mail that need addressing * clamd improperly installed; re-do using yum and integrate back into amavisd * spam detection a bit too generous; better techniques? - emergencies * security issues * work with host if hardware or other failure to help resolve (host is in Missouri, so phone contact of course) We are expecting more hours initially for setup of new server and cleanup of existing issues, then perhaps a weekly checkup as you may recommend to us. SSH certificate for root. Non disclosure and data security agreement required. A methodical person who documents and who can teach (without pain) would be ideal. I never ask the same stupid question more than once (sadly, the second time I may, however, re-phrase it). mark richards SolarWave mark-dot-richards-at-massmicro-dot-com

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?

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.
