For all but one, this has proven tedious, but relatively painless. My package.use file is another story: at over three-hundred lines, the thought of manually converting this to a directory structure does not attract me. Are there any tools in Portage to help with this, or must I resort to writing a shell script ? I'm not aware of a tool to do the conversion. However there may be one that I'm not aware of. For example, considering the following lines in my flat package.use: media-video/openshot printsupport sys-apps/util-linux tty-helpers I want to take this file and create a directory structure: media-video/openshot, containing "media-video/openshot printsupport" sys-apps/util-linux, containing "sys-apps/util-linux tty-helpers" I wasn't aware that you could put sub-directories in /etc/portage/package.use. I've always had to put the files directly in that directory, not sub-directories. As such, my files have names like sys-apps-util-linux to avoid naming collisions. Perhaps things have changed since I last tried to use a sub-directory or I am misremembering. How can this be done ? I think it should be relatively easy to script reading the line, extracting the package name, munging the name, and writing the entire unmodified line to a new file based on the munged name. If directories work, create and populate them without munging names. -- Grant. . . . unix || die

Ew. I can't say as I'm surprised about that, given the nature of SMTP servers in the '90s. I wonder what the licensing would have been to have one machine sending outbound and another receiving inbound. Though that does assume that you could have multiple SMTP gateways connected to MS-Mail. You could pretty much guarantee most mornings I'd be in the server room deleting a bunch of private emails from the outgoing queue, and repeatedly rebooting until the queues in both directions managed to clear. Oy vey! The point is that when the server sends EHLO, it is *not* a *permitted* response for the client to drop the connection. That was the specification for ESMTP - the client should reject EHLO, the server tries again with HELO, and things (supposedly) proceed as they should. Which they can't, if the client improperly kills the connection. Agreed. Which shouldn't have been a problem. ESMTP was designed to fall back gracefully to SMTP. But if clients don't behave correctly as per the SMTP spec, how can the server degrade gracefully?

Be it CALs, upgrade licensing, etc. Nowadays they prefer to cripple Outlook with non-Exchange protocols, so that our users complain about not having shared calendars when we've had CalDAV integrated with IMAP for 10+ years. CalDAV is decidedly not an email protocol; POP3, IMAP, SMTP. I'm not aware of Outlook ever claiming support for CalDAV. It has supported POP3, IMAP, SMTP, Exchange proprietary protocols, and likely NNTP. You can get shared calendaring, address books, and folders without Exchange. I used MAPIlab's Colab product for a number of clients for many years circa 2010. It is (was?) an Outlook add-on that added support for accessing a shared PST file. It worked great in multiple client's offices of between 5 and 25 people. (My bigger clients had Exchange.)

It may have been a SHOULD. The ISP chose to make the change that resulted in ESMTP. Also, I'm fairly sure that MS-Mail didn't include SMTP in any capacity. It required an external MS-Mail SMTP gateway, which I Microsoft did sell, for an additional cost. The *ONLY* acceptable reason for terminating a connection is when you recieve the command "BYE", so when Pipex sent us the command EHLO, MS-Mail promptly dropped the connection ... I'll agree that what you're describing is per the (then) SMTP state machine. We have sense seen a LOT of discussion about when it is proper or not proper to close the SMTP connection. If the MS-Mail SMTP gateway sent a 5xy error response, it could see how it could subsequently close the connection per protocol state machine. Pipex, and I suspect other ISPs, had to implement an extended black list of customers who couldn't cope with ESMTP. If the MS-Mail SMTP gateway hadn't closed the connection and instead just returned an error for the command being unknown / unsupported, Pipex would have quite likely tried a standard HELO immediately after getting the response.

No, what I'm talking about are vendor-provisioned RedHat VMs. I was having problems sending emails from my server due to lack of reverse DNS for the IP in question. When I asked the provider if they could set up reverse DNS for that IP, they said no they can't because that IP is shared with other VM hosts. Therefore, it's not possible for them to map that static IP address to my FQDN. IIRC, I send email through sendgrid. If I wanted sole usage of a static IP (which would allow reverse DNS), I'd have to move up a tier in the product list and pay more. That said, the VM in question does have two virtual web hosts (with separate FQDNs) which would share the same IP even if I did cough for the next higher tier where that VM has sole ownership of a static IP. I only need to send mail from one of the two FQDNs that poit to that IP, so that would be OK. -- Grant

My best guess is that you have a protection method in place in the event that the reverse D.N.S.\ does not match the forward ? You're close. I do require reverse DNS. I will log a warning if forward and reverse don't match, but the email should still flow. Lack of reverse DNS is problematic though. As I'm on a domestic I.P., this is out of my control (i.e., `nslookup mail.suugaku.co.uk` returns my I.P., but `nslookup ` returns some obscure hostname provided by my I.S.P.). Oops! Been there. Done that. I've added your mail server's name & IPv4 & IPv6 addresses to my /etc/hosts file. Please try again. I'll also send you an email from an alternate address. Sadly, it doesn't look like you can use the hack that I've used in the past. If forward and reverse DNS do match , you can configure your outgoing email server to simply use that name when talking to the outside world. Unfortunately, it doesn't look like you can do that because the forward DNS doesn't return an A / record for the name name that the PTR returns. This sounds quite enticing; I'll have a look, thanks :) :-) I didn't mean to infer that my back-up server would be different to my primary server, as my primary is rather minimal. And yes, good point, I suppose if anything, I should have tougher anti-spam measures on my backup MX :) For simplicity and consistency sake, I'd encourage you to have the same spam / virus / hygiene filtering on all mail servers that you control. This is what I was intending to do. I hadn't even considered dynamically playing with the D.N.S., given that addresses are commonly cached for a short period to avoid hammering name-servers (?) You have influence on how long things are cached for by adjusting the TTL value in your DNS. I say "influence" vs "control" because not all recursive DNS servers honor the TTL value that you specify. Some servers set a lower and / or upper bound on the TTL that they will honor. Oh my goodness, I feel silly now :) I was considering just using courier to catch the incoming mail, and then rsync it over to my primary when it comes back on-line, I supposed that you could have a full functional mail server, including delivering to mailboxes and then synchronizing the mailboxes between the servers. But that would be more work, and I'm guessing that's contrary to the simple alternate server that I think you are after. but using an S.M.T.P.-forwarder certainly seems more elegant. ;-) Cheers for your help and detailed explanations Grant.

Having the email on an alternate server without a way to get the email to the main mail server where all the clients are configured to access it is an untenable situation that is tantamount to not having the email that goes to the alternate server. What do you think; is this at all possible ? Yes, absolutely possible. Has anyone here done anything like this before ? Yes, absolutely been done before. What you're asking for can all be hacked together using things other than SMTP. But it is very much that, a hack, cobbled together.

So, you would be waiting on them for that day / week to re-send, presuming they do re-send. Conversely, if you have your own secondary mail server, the inbound message will likely land at the secondary mail server seconds ~> minutes after being unable to send to the primary mail server. Thus when your primary mail server comes back online minutes later, your secondary can send it on to your primary. Thus a net delay of minutes vs hours / days / week(s).

The configuration file is far from impossible to understand. Calling it a configuration file is sort of a misnomer in that it's more of a programing language than a configuration file. Some have even said that it's Turning complete. It does have some things going against it though. 1) It is highly dependent on the tab character (one or more) being used to separate two parts of specific lines. This is easily visually lost as well as frequently lost with bad copy & paste. But it's trivial to know about and correct. (Compare that to Python that has lost all of it's leading white space.) 2) The "config" file is really multiple sub-routine that are called in specific instances and do very specific things. You must know which one you need to use when. 3) Sendmail's logic is different than what most people are used to. It's not quite RPN. But it's different enough that many people have problems with it. I think it's more like relay logic. Each line in a rule-set has an opportunity to apply to the current working space. Each line can modify the working space, possibly directly or indirectly by calling other things. If you aren't careful, the working set can be inadvertently matched by multiple lines (rules). As such, the working set is specifically modified so that other lines don't match if they should not. There is a lot of pattern manipulation to keep track of and it takes practice. I'm sure that there are others. But those are the big ones that come to mind at the moment. At it's peak back in the early 90's there were approximately five people in the world who actually understood sendmail, and none of them ever worked where you did. I don't know about the '90s, but I do know that in the '00s and '10s, your statement is exaggeration to the point of being hyperbole. I have witnessed an active Sendmail support community for about 15 of the last 20 years. Most of that support was via the comp.mail.sendmail newsgroup. The rest of us stumbled in the dark using the finely honed cargo-cult practices cutting and pasting random snippets out of example configurations to see what happened. Your lack of use of resources doesn't mean that said resources wasn't available. Usually what happed is that mail was lost or flew around in a loop multiplying to the point where a disk parition filled up. Yep. That said, sendmail has features that no other MTA has. For example, it can transfer mail using all sorts of different protocols that nobody uses these days. It's not just (on the wire) protocols that sendmail supports. Many of which are effectively obsolete save for specific microcosms. Sendmail also supports interfacing with other programs in a very flexible manner. It is fairly easy to have Sendmail support Mailman (et al.) in such a way as that you don't need to change anything on the email server when adding or removing mailing lists. No, I'm not talking about automated alias generation. There is no need for alias generation when Sendmail and Mailman are connected properly. Sendmail quite happily supports LMTP into local mail stores / programs. This is quite handy when you want something like a recipient's sive filter to be able to reject a message. Back in the 90's a number of replacement MTAs were developed such as qmail, postfix, exim, etc. When you installed one of these, (instead of the classic sendmail), they would usually provide an executable file named "sendmail" that accepted the same command line arguments and input format that the original did. That allowed applications who wanted to send email to remain ignorant about exactly what MTA was installed. Yep. The "sendmail" command has become a de facto industry standard that most MTAs emulate. -- Grant. . . . unix || die

Your CGI scripts passed the message off to the queuing MTA and didn't need to worry about what to do if the remote mail server couldn't be reached.

I take exception to that for multiple reasons: 1) Bootstrapping - you can't learn something without actually using it. 2) I've been quite happily using Sendmail on multiple platforms for 20 years. 3) Sendmail is capable of working in every single email scenario that I've seen in said 20 years. The same can't be said for other MTAs. If all your mail gets sent via a single SMTP server at your ISP (or wherever), then Sendmail is definitely not what you want. That depends. If you have a fleet of Sendmail servers, chances are good that you will prefer to re-use the same solution, even in small / simple role. Read: The Devil that you know. If you don't need local queueing (so you can send email while offline), then I'd pick ssmtp. (20)ProTip: You really do want local outbound queueing /somewhere/ on box. You don't want your web application to error out when it can't reach it's SMTP server. You don't want t loose that receipt for the transaction that the customer just made. Can you regenerate the receipt? ;-) You can have each application do it's own queuing / re-sending, r you can rely on the local MTA to do it for you. Where do you want the queuing complexity? A local queuing MTA is simple and solves a LOT of problems. If you want something even more sophisticated (e.g. something that can deliver mail locally and receive inbound mail using SMTP), then postfix or exim would probably the be the next step up: I would add Sendmail to the front of that list. But I might be biased. I've read claims that there are things you can do with sendmail that Exim or Postfix can't handle, but I'm not sure I believe it. I am sure I'll never need to do any of those things. I don't know Exim or Posfix well enough to comment with any authority. I do know that I Sendmail, Postifx, and Exim all handle (E)SMTP without any problem. I think that Postfix can be made to handle UUCP. Sendmail has four different ways that it can use UUCP, built in. I have no idea about Exim. Sendmail can easily work with other protocols, Mail11, fax, pager, news gateway (send and / or receive). It's also easy to add additional protocols without needing to recompile anything, only configuration changes are needed. I don't know where in the list I lost Postfix and / or Exim, but I expect that they didn't make it through the last paragraph. For a long time, Sendmail did have one claim to fame that no other MTA had. Specifically Sendmail had the ability to use milters (mail filters) and filter email during the SMTP transaction. It's trivial to hook ClamAV, SpamAssassin, and just about anything you want into checking mail during the SMTP transaction such that you have the ability to reject, not bounce, the message. Thus making the sending host be responsible for it. I'm sure there are many more and far more esoteric things that Sendmail can do. Though I doubt that many of them are as germane today as they were in the mid '90s. I was recently playing with the ability to have a domain spread across multiple servers and configuring Sendmail to route messages to the proper back end server, a feature known as LDAP routing. Yes, Sendmail has a lot of power, much like unix. It will happily hand you a loaded gun, encourage you to point it at your feet and empty the magazine as fast as possible. When you're done, it will help you reload and do it again. If you know how to wield this power Sendmail can be a wonderful tool that can be used in all of the scenarios described in this thread. It's also relatively trivial to have Sendmail be a basic queuing outbound only MTA that uses ISP smart hosts to provide SMTP services to local applications.

Exim, postfix, qmail and the others were all still full-function MTAs intended for a multi-users system. They could route mail to different destinations (including delivering it locally to a variety of mailbox types) and accept inbound email from other MTAs. While they were far easier to set up and maintain than the original sendmail, they were still massive overkill for a computer that was used only by a single person where reading mail was done via POP/IMAP and all outbound mail was handed over to a single outside mail relay. They often didn't deal well with the fact that they were running on a host that didn't have a "real" hostname that meant anything to the outside world, and that the local hostname had nothing to do with the email addresses of the user(s). For that use case, simple MTAs like msmtp, ssmtp, and nullmailer were written that don't handle incoming mail at all, and where all outbound mail is sent to a single mail relay host. The first two don't even do any queuing: if you try to send mail when your relay host is unreachable, then the send simply fails. These too, when installed, provide an executable named "sendmail" that accepts the same command line options and input format as the original.

What application would people recommed to add some simple annotations to image files? For example, I'd like to add a few arrows, some text, and maybe a box or oval or two. I sometimes do stuff like that from the command line using ImageMagick's "convert", but drawing arrows with that is pretty painful. I found x11-misc/shutter, which I think can do it, though I don't need the screenshot capability.

[gentoo-user] Python: ebuilds vs. pip3 install --user
Background: a utility written in Python that I use regularly
(weasyprint) was out-of-date and is being dropped from Gentoo's
package database. I tried (and faield) to creaate an ebuild for a
more recent version. So I ended up doing
$ pip3 install --user weasyprint
That installed weasyprint and a few depdendancies (tinycss2,
defusedxml, ciarocffi) under ~/.local/{bin,lib64}.
Question:
Can those dependancies installed under ~/.local cause problems for
things that were installed using standard ebuilds which require
older/other versions of those libraries (which were installed using
standard ebuilds)?
For example, weasyprint requires cairosvg 2.4, and 2.4.2 was installed
under .local via the pip3 command shown above.
My stable cairosvg is 2.0.3 and it is installed in the usual "system"
location /usr/lib64/python3.6/site-packages by the normal "emerge"
process. [IIRC, at one point I tried unmasking 2.4.2, but that caused

Note that the person behind the attack doesn't need physical access. If an attacker can shove malicious firmware into something like a PCI card with DMA bus-master capabilities, then on power-up that card can carry out the attack. However, getting the firmware into the PCI card would probably require root privledges, so there would need to be a pre-existing privledge-elevation vulnerability. I think. :) -- Grant

A clock that varies like that is usually referred to has a "spread-spectrum" clock. If properly implimented it has no measurable effect on software execution (even for real-time cases) because the variation is done so that the average frequency is "constant" and the deviation from that average sums to 0 for any significant period of time (anything over a few hundred microseconds). The variation of the average over temperature and supply voltage is usually far more significant. -- Grant Edwards grant.b.edwardsYow! PIZZA!! at gmail.com

[gentoo-user] revdep-rebuild ignoring SEARCH_DIRS_MASK
Has anybody else noticed that revdep-rebuild recently started to ignore SEARCH_DIRS_MASK? I have it set thusly in make.conf SEARCH_DIRS_MASK="/usr/lib/digilent/waveforms" and that used to prevent revdep-rebuild from reinstalling sci-electronics/digilent-waveforms every time (it's a binary install that has it's own version of a bunch of shared libraries). Sometime in past month or so, revdep-rebuild started to reinstall it every time despite the SEARCH_DIRS_MASK. AFAICT, the layout of the waveforms package hasn't changed. When I add --verbose to the revdep rebuild, all of the files that trigger the reinstall appear to be under the masked directory. -- Grant Edwards grant.b.edwardsYow!

Re: [gentoo-user] External hard drive and idle activity
On 1/1/20 5:09 PM, Dale wrote: Howdy, Hi, As some may recall, I have a 8TB external SATA hard drive that I do back ups on. Usually, I back up once a day, more often if needed. Usually I turn the power on, mount it, do the back ups, unmount and turn the power back off. Usually it is powered up for 5 minutes or so. When I unmount it tho, I sometimes notice it is still doing something. I can feel the mechanism for the heads moving. It has a slight vibration to it. Questions are, what is it doing and should I let it finish before powering it off? I'd assume that once it in unmounted, the copy process is done so the files are safe. I guess it is doing some sort of internal checks or something but I'm not sure. There might be some activity for up to 30 seconds after umount finishes and returns to the command prompt. Note: umount will normally block until buffers are flushed to disk. Is it safe to turn it off even tho it is doing whatever it is doing? I wouldn't. Should I wait? I would. Does it matter? Maybe. Is the drive SATA connected or USB connected to the machine? In some ways it doesn't matter. You can tell the kernel to eject the drive. Once that finishes, there is no active remnants of the drive in kernel. 5–15 seconds after that and you should be quite safe to power the drive off. echo 1 > /sys/class/block/$DEVICENAME/device/delete That will cause the kernel to gracefully disconnect the drive.

QEMU itself does not use NBD. Thus QEMU does not need to depend on qemu-nbd.

Re: [gentoo-user] qemu / nbd
On 12/4/19 11:03 PM, Walter Dnes wrote: nbd is a "Network Block Device" driver along the lines of NFS, but it doesn't handle concurrency. https://nbd.sourceforge.io/ I think I'd liken NBD to iSCSI more so than NFS. Primarily because both NBD and iSCSI provide local block devices that are backed by something across the network. Conversely, NFS provides access to regular files from across the network. You can put a file system on an NBD / iSCSI block device if you want, but you don't have to. Conversely, NFS is a file system and doesn't require putting a file system on top of it. But it's generic, and can handle any *REGULAR* file system, not just NFS. NFS is not a file system in the /typical/ sense. There is no mkfs.nfs. NFS is a file system in the sense that it is mounted and provides access to files. QCOW2, or raw, or whatever, is a special QEMU format. So it requires QEMU libs (i.e. qemu-nbd) to decode QCOW2/RAW. Why doesn't qemu have a dependency on NFS? It doesn't, nor does it need to. Same answer; they're both remote network block device systems that most linux users don't need, NFS is not a block device. and they're both unrelated to the core functionality of QEMU. QEMU can use image files (qcow(2) or raw) on any mounted file system. NFS qualifies as a mounted file system, but that is completely outside of QEMU. Normal file systems can be put on NBD & iSCSI devices and mounted, but that is also completely outside of QEMU. QEMU proper will not use NBD devices (directly) itself. qemu-nbd is a utility to act as a NBD server to allow the Linux kernel to be an NBD client to access qcow(2) image files. qemu-nbd is not /needed/ for normal QEMU operation. -- Grant. . . . unix || die -- Grant. . . . unix || die

The C7 is the older, more expensive version that's supported by the released, stable version of OpenWRT. The A7 is newer and requires the latest "snapshot" version of OpenWRT.
