I have over 30 years experience in all phases of software development and delivery. I have administered a variety of midrange servers, and worked with systems from PCs to Mainframes.

comment Send emails with a custom From: field
@forberg Multiple from addresses are likely to trigger spam filters. I've only seen multiple from addresses in spam. Look at adding a Reply-to: address if you need multiple addresses.

comment dnsmasq - flooding daemon.log with messages
@ethrbunny Is there anything in your dns leases file. (Likley /var/lib/misc/dnsmasq.leases?. The first field should be the expiry time of the lease.

comment dnsmasq - flooding daemon.log with messages
@etherbunny At this point I would break out tcpdump or dhcpdump and check the contents of the traffic. These messages should only be generated in response to requests.

comment Trust a self signed PEM certificate
@AlexSchröder I've edited above. They should not import your snakeoil certificate, but if you've setup your own CA, it is reasonable for them import your CA. I haven't yet identified trust issues between SMTP servers. Most clients can be told to trust individual certificates.

The command ipconfig will show the IP address, if any, your Windows 7 has accepted.

Is the client accepting the offered address? Try ipconfig. The client should only renew every 6 hours or so.

comment Reverse DNS with BIND and IPv6
@Shilgen The host lookup shows that the PTR lookup is working. That is the expected output. What do you think is not working?

comment Howto Configure IPv6 on a Debian based system?
@raz Auto-configuration using RA (Router Advertisement) packets will configure the router as well as the IP address. Link local addresses also auto-configure, but aren't routeable and don't configure a router.

comment One-way-sync a directory, but leave deleted files deleted on the destination
@maxschlepzig See my edit for three options. (One is to use a tool more appropriate for incremental transfers.) Rsync is not designed to automatically handle your use case.

comment How to grab the oldest unread message from `mail` in a script?
@warren Your mail server should be configured to deliver to a certain type. The mail command reads from the users inbox in /var/mail. Maildir delivery uses a directory tree, usually called Maildir and locate in the user's home directory. I haven't knowingly worked with the third format.

comment Forward Only Email Server
It doesn't appear the server is receiving any messages. Try using telnet to diagnose. SMTP is a conversational protocol easy to emulate using a terminal session. For GMail, you likely want to setup an authenticated outgoing connection.

comment How to detect the incoming httpd Connection Counts of each VHOSTS?
@夏期劇場 Using the server-status modules output will give the current state when run. I have updated my response accordingly.

comment Removed /var/lib. Can't open Desktop
@Joshua You may be able to work around the failure to fetch the file by using wget to fetch it. Then you can use dpkg -i to install. The essential packages are the critical ones. You should be able to get a list with the command aptitude search ?essential. The base-files package is likely the most important.

comment Removed /var/lib. Can't open Desktop
@Joshua Pipe the output to less by adding | less to the command. You can use the list to reinstall the packages by piping to xargs -n1 aptitude reinstall instead.

comment Removed /var/lib. Can't open Desktop
Try reinstalling base-files then retrying reinstalling the essential packages. You are likely to encounter some more dependency failures. You can also try a -force option to reinstall anyway.

comment SSH E-mail login alert if SSH port is as NAT
@Mato If you are running a tool to snoop the SSH session just have it email on connection, or wrap it and log as in the second case.
