It works for the most common stuff at least. However, if no one shares data with the site that has some obscure package or command, it reports no hits. http://www.portagefilelist.de/site/query I did a couple searches but it might be that you had typos in at least one of the file names you are looking for. You may want to try the search and make sure you have the names spelled correctly. Another thing to consider, you could have a USE flag disabled that needs to be enabled to turn on the features you want. That may be needed for more than one package. Hope this helps. Dale :-) :-)

I only use ssmtp for situations where mail is only sent by an application I'm interacting with and where I can _see_ that the send failed and can save/postpone the message while I fix whatever's broken that caused the failure. > But I really object to the "ultra-professional" comment, because > everybody has to start somewhere.

I think that's an inaccurate statement. First, m4 is a macro package, not a compiler. Second, the macros are used to reduce the size of the macro config (mc) file to something manageable instead of hundreds of lines that are easy to cause a syntax mistake. Third, the macros made the mc file more semantics in nature instead of Sendmail config file (cf) specific. Meaning that one line allows changing values in multiple places that use the common information, like the domain name(s). My home system has a 33 line mc file (including comments) that expands to 1915 lines of cf file (including comments). Both the input and output is ASCII text. Humans can read both of them. Humans that understand cf syntax can read both files. This is far from turning something into byte code. -- Grant. . . . unix || die

On 4/2/20 8:23 PM, Grant Edwards wrote: It's very powerful but the configuration file format is almost impossible to understand, so people developed an m4 application that accepted a _slightly_ less cryptic language and generated the sendmail configuration file. 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

In this context, ebuild as a reference to the MTA known as Sendmail. i used to think it's a swiss-army kind of tool (used to call "sendmail" in my cgi scripts decades ago without any infrastructure; by just directly zapping recipient's smtp gateway). Yes, Sendmail can e a Swiss Army knife. That's one of it's advantages. That's also one of it's disadvantages. Your historic use of Sendmail is an example of using a local queuing MTA. 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. You didn't have to bother with detecting the error and reporting it to the end user via the web form. You didn't have to bother with storing information for later retry.

On 4/2/20 8:18 AM, Grant Edwards wrote: Then DO NOT use sendmail. Sendmail is only for the ultra-professional who already knows how to configure it (not joking). 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.

In light of the real problems related to COVID-19 I couldn't care less about fake eye contact if I actively tried. However, business has been very slow lately.

Re: [gentoo-user] aggregate logs into Elasticsearch
* Stefan G. Weichinger: > My goal: > > collect logs of postfix, nginx into the docker-containers running ES, > Kibana .. and learn my way from there. If you are not dead-set on Elasticsearch et al, I propose considering MongoDB as an alternative. There are syslog Modules that allow logging into MongoDB directly. On the DB side, collections (roughly equivalent to tables in relational databases) can be limited by size or by age, meaning that removing older data will happen automatically if you so wish. MongoDB also makes it easy to add data from sources with different data makeup to shared collections, because there is no rigid table structure. For analysis, MongoDB includes its own Aggregation Framework[1], which is a very powerful and versatile. While probably not relevant to your needs right now, It even comes with built-in geolocation search [1] https://docs.mongodb.com/manual/core/aggregation-pipeline/ I think very highly of MongoDB and encourage you to look into it as a possibility and as an interesing technical concept. -Ralph

On a lot of news T.V.\ channels, they place the camera quite far away from the newsreader, making it almost impossible to notice they are looking at the teleprompter, instead of directly into the lens. Maybe that would be a solution to this pressing issue ? Alternatively, dark glasses could be used, or even better, glasses with painted eyes on them from the local joke shop. If you were feeling sadistic and wanted to further the misalignment, how about glasses with spring-loaded eyes ? -- Ashley Dixon suugaku.co.uk 2A9A 4117 DA96 D18A 8A7B B0D2 A30E BF25 F290 A8AA signature.asc Description: PGP signature

While fast, I have more time than I do money. I do try to keep my rig in a good place as far as age tho. I may try to upgrade my mobo in a couple years but stick with my current CPU and memory. Mobos do go bad with age, I've read about caps blowing their top and stinking up a room quite well. While I don't edit videos, I do have several terabytes of video. I mostly just play them tho and they play fine with no skipping or anything so what I got is plenty fast for that. I mostly just want the OS itself on something faster but also newer since that HDD I have now has some age on it. I still find the nvmes interestingly fast. Wow!! Dale :-) :-) P. S. My top fan in my Cooler Master HAF-932 case got stuck the other day. It stopped spinning and gkrellm was kind enough to let me know that. I took it out, oiled it good and it works fine again. I also oiled the side fan and the front fan. I got some high dollar gun oil I use for those. It's super slick, handles a wide range of temps and lasts for ages. I've used it in several fans. Even my old CPU cooler fan still runs. I replaced it over a year ago. I use the old one to dry counter tops, dishes and cool batteries I'm charging.

I wish it did. Well, raw throughput is great ’n all, but in real-life you won’t notice much difference between a SATA and an NVME drive. The bottleneck quickly becomes the CPU again during boot or loading more complex applications (browser, office). The biggest improvement in those situation comes from the fast “seeking” and reading of many small files. HDDs are at a big disatvantage here due to their moving head and mechanical seeking. In fact I doubt you have many use cases for reading many gigabytes at a time over and over again every day without much CPU overhead, like video editing (loading previews in 4K or 8K), copying, archiving, checksumming and so on. Due to their immense speed, those NVMEs also tend to heat up quite a bit under load, eventually leading to throttling. So from a practical POV, and since you’re on a budget, I suggest cutting cost by staying with SATA. -- Gruß | Greetings | Qapla’ Please do not share anything from, with or about me on any social network. “He doesn’t know how to use the three seashells!” signature.asc Description: PGP signature
[gentoo-user] Unstable package "xfce-base/xfce4-session-4.14.2" segfaults
Greetings, when I installed my first Gentoo system on my laptop back in September I had to accept the "~amd64" keyword for quite a few "xfce-*/*" packages due to stable versions not being available at all for some packages, and due to several of these unstable packages requiring unstable versions of their dependencies. But it worked, at least until recently: After a routine upgrade of Gentoo I could no longer hibernate nor susp- end my laptop. Rather I was simply confronted with a new login screen and my former session was gone completely. After I found the following in "/var/log/syslog" Apr 3 13:37:16 tux kernel: xfce4-session[11142]: segfault at 8 ip 55eff2f87539 sp 7ffc8409e470 error 4 in xfce4-session[55eff2f75000+1c000] Apr 3 13:37:16 tux kernel: Code: 48 8d 35 fa e6 00 00 48 8d 3d b0 9d 00 00 e8 be dc fe ff 31 c0 eb c2 66 2e 0f 1f 84 00 00 00 00 00 48 8b 04 24 31 f6 4c 89 ef <48> 8b 50 08 31 c0 e8 cc b2 ff ff 4c 89 e7 e8 24 f3 fe ff b8 01 00 Apr 3 13:37:16 tux lightdm[9818]: pam_unix(lightdm:session): session closed for user rainer Apr 3 13:37:16 tux polkitd[5036]: Unregistered Authentication Agent for unix-session:/org/freedesktop/ConsoleKit/Session2 (system bus name :1.42, object path /org/gnome/PolicyKit1/AuthenticationAgent, locale en_GB.utf8) (disconnected from bus) Apr 3 13:37:16 tux sudo[4135]: pam_unix(sudo:session): session closed for user root I checked the "emerge" logs, and sure enough package "xfce-base/xfce4- session" had just been upgraded to new unstable version 4.14.2. So I again downgraded it to version 4.14.1 (which meanwhile is stable), and the problem went away. Thus in case any of you is using the currently unstable version 4.14.2 of package "xfce-base/xfce4-session", beware! Sincerely, Rainer

[gentoo-user] aggregate logs into Elasticsearch
I am trying my first steps to collect and aggregate logs into a elasticsearch/kibana combo. I have them in a docker-compose stack and want to collect nginx and postfix logs for a start. So far I am confused by stuff like filebeat, logstash, fluentd ... brrr Could someone explain or even share some config files? How to set that up without dozens of packages installed etc (fluentd pulls a lot of packages, for example). My goal: collect logs of postfix, nginx into the docker-containers running ES, Kibana .. and learn my way from there. thanks, Stefan

How about looking at the camera when you're talking, and looking at the screen only when absolutely required ? This isn't really a computing issue, but more one of basic etiquette. If you were in a real meeting and you had some documents in front of you, I would think it superfluous to use technology to average out the position of your eyes (which would unlikely work anyway). I very much doubt that anyone would find it offensive if you failed to constantly stare at them throughout an entire interaction, and some may even find it off-putting. -- Ashley Dixon suugaku.co.uk 2A9A 4117 DA96 D18A 8A7B B0D2 A30E BF25 F290 A8AA signature.asc Description: PGP signature
[gentoo-user] Idea for Videoconferencing (Video part)
Hello, this is not exactly a gentoo issue. But due i am using gentoo i am asking here. Problem: Usually the camera is outside of the screen. The user normally looks at the screen. As result the communication partner(s) see him not looking at the camera. Idea: Use two cameras positioned left and right or top and bottom of the screen. Combine the two video streams and generate a third stream having a virtual camera positioned at the middle of the screen. Result: Better communication. The partners always looking in their eyes. At the same time the screen contents can be viewed. Is this description clear enough ? Sounds that feasible ? Anyone taking the task ? Or is there a better place to post such an idea ? kind regards Petric
