I have Raspberry Pi 3 and I use it as a Wi-Fi access point. I use Raspberry Pi 3 built-in Wi-Fi adapter for this.
Until today, the access point worked.
Today it stopped working. I think that Raspberry Pi crashed and I then turn the power off without shutting it down. Since then, it doesn't work.
If I run it as service, the status will show running (exited).
When I run it with sudo /usr/sbin/hostapd -dd /etc/hostapd/hostapd.conf, I get the following errors and it doesn't work:
random: Trying to read entropy from /dev/random

Access point started working now, but I didn't change anything. Maybe there were some corrupted files, but the system repaired them after a few reboots.
I also got answers on Raspberry Pi Forums by epoch1970. I don't know if they would fix the problem, but they are mostly about corrupted files, so they probably fix the problems.

I am having a problem with Google's SMTP servers. They reject my SMTP server's IP for no valid reason. My server complies with all the necessary rules to deliver the message but Google rejects it by IP without giving me details and I cannot find support either. I have written to postmaster#gmail.com but got no response. My server sends notifications to the users of the system, it does not do SPAM and apparently everything is correct. I don't see a valid reason for this crash, and I can't find a way to fix it. I would like to know if the same thing happened to someone and how they could solve it. Next I copy the console with the delivery attempt and additionally some DNS checks that show that apparently there is no problem on my server:

root#venabili:~#
The domain in question is tecnologica.com.ar and I leave a link to some verifications where it is seen that the RR SPF, DKIM, DMARC, _SMTP._TLS, _MTA-STS, MTA-STS, CAA and PTR are correct and it is not a open relay:
https://mxtoolbox.com/domain/tecnologica.com.ar
The certificates are signed by Let's Encrypt. The host name matches the certificate. The classes are correct. And finally, I do not SPAM. I would greatly appreciate a help because at this point I am completely disoriented and can't find what else to do.
I am not looking for a solution but rather where I can find it.
Thank you very much for your help

I'm trying to test MQTT-SN.
I'm using Mosquitto Broker, Paho MQTT-SN Gateway and this library (https://github.com/S3ler/arduino-mqtt-sn-client) for the clients.
I'm using an esp8266 as a client.
With this client, I can connect, subscribe, receive from subscribed topics but I cant publish into topics
memset(buffer, 0x0, buffer_length);
mqttSnClient.publish(buffer, publishTopicName , qos);
Every time I try to publish with this client, Mosquitto gives me
Socket error on client <clientid>, disconnecting
And my client disconnects from the Broker.
Any clues?

Thank you for the help Dalton Cézane.
But I found the problem in an open issue in the client's library:
Having trouble with your example WiFiUdpMqttSnClient program in that
it does not successfully publish the test messages. I'm using
paho-mqtt-sn gateway.
I'm bashing around in the dark a bit but I think this is because it
publishes the messages with the flag TopicIdType set to 2. I think it
should be zero (normal) because it's not pre-registered nor is it a
short topic.
In file MqttSnClient.h line 216 the call to send_publish has
short_topic set to true. But that's not all; in file mqttsn_messages.h
around line 215 if short_topic flag is false it sets the flag to
predefined. I've removed the latter 'else' clause so the flag is set
to zero and I can now publish successfully.
I suspect my hack is not a complete solution but I hope it helps you
resolve this issue.
This comment was made by #nottledim, big thanks!
Now i can publish without a problem using my esp8266.
Just leaving here if anyone has this problem.
link to the issue: https://github.com/S3ler/arduino-mqtt-sn-client/issues/3
This problem is with Ubuntu 16.04 running on a mobile device BQ E4.5.
I have at home a Wifi AP (AVM FRITZ!Box WLAN 3170) and a bunch of Linux and FreeBSD laptops and 4 phones BQ E4.5 connected to it. All do fine, but since some month one of the E4.5 running the latest developer channel can not connect anymore to my AP. It started (IIRC) somewhere in December, first being unstable on connect and after some days it could not connect at all anymore. The connection is always rejected from the AP with a package CTRL-EVENT-ASSOC-REJECT (see debug log below). As this E4.5 is only my test device and as this can connect without any problem to all other AP, I mostly don't care. Really, I have not found any other AP, not in public, not in my office, to which the device can't connect. That's why I think the fault must be in the AP or in the radio environment in my house (I tested all channels), but as this AP does not offer any log for debugging, I can't debug this from this side.
I managed to monitor and raised the debug level with wpa-cli in the E4.5
via "adb shell" and have here the log of one connection attempt.
Is there any Wifi expert to see from the log why it gets rejected?
Is this problem somewhere known in UBports or UBphone (Canonical) land?
PS: Please don't think in AP's blacklist (as this AP hasn't one) or in
invalid psk. I run Wifi for many years and know what I do :-)

I have a database filled with a lot of logged IPV4 messages. It is used to get queries like: "give me all messages from MacAddress ... that were logged in the period ... to ... that have ..."
Some queries will result in a huge amount of logged messages. Therefore we decided to make a PCAP file if such a request was made.
"Please create a PCAP file containing all logged messages from your
database that ..."
So upon request, my service should fetch the requested data from the database (in pages) and create a PCAP file filled with the data fetched from the database. Later callers can ask for a read-only OWIN stream to this file
The service can create such a file. The problem is that it is not recognized as a proper WireShark file.
I've read Libcap File Format. Whenever I have to create a file filled with LoggedMessages I fill a binary file as follows.
Global Header
Per logged message:
A packet header
Packet data with:
Ethernet Frame: Destination Mac, Source Mac, EtherType (0x800)
IPV4 header
Logged Data
Wireshark starts complaining about the file when it attempts to read the Ethertype. It says this is a Length. Definition of Ethernet Frame with EtherType
So below I show the start of my file. Hexadecimal format per byte + my interpretation of it. After that the comments from wireshark
The created stream starts with the Global Header: a 32 bytes structure. First the hexadecimal values then the interpretation:
=== Global Header ====
D4 C3 B2 A1 02 00 04 00
00 00 00 00 00 00 00 00
FF FF 00 00 01 00 00 00
Magic number A1B2C3D4 (Original Time Precision)
Version: 2 - 4
ThisZone 0
sigFigs 0
snapLen 0000FFFF
datalinkType 1
Note that the magic number has the LSB first, indicating that every multi-byte number will have the least significant byte first. So a 2 byte value of 0x1234 will have in memory first 34 then 12.
After that the Packets should come. Every time one Packet Header, followed by one Packet Data
=== Packet header ===
09 89 58 5A C8 85 0B 00
6B 00 00 00 6B 00 00 00
Timestamp: 1515751689.7551446 (usec precision)
Number of saved bytes (incl_len) 107 bytes (0x006b)
Actual packet length (orig_len) 107 bytes (0x006b)
=== Packet Data ===
CF 31 59 D3 E7 98 53 39 - 17 F0 A9 9C 00 08 45 00
5D 00 00 00 00 00 FF 00 - E0 0D 8A 84 77 44 E0 2B
9C FB 4D 43 D5 8A 00 00 - 00 00 41 41 41 41 41 41
41 41 41 41 41 41 41 41 - 41 41 41 41 41 41 41 41
// etc, until total 107 bytes
The packet data consists of a Mac Header, IPV4 header and a couple of 0x41 as data
=== Mac Header ===
Destination Mac: CF:31:59:D3:E7:98
Source Mac: 53:39:17:F0:A9:9C
Ether type: 0800
Note that the magic number showed that every multi-byte number has the LSB first, so the two bytes 00 08 will have a 16-bit meaning of 0x0800
If you look at the PCAP file interpretation I show below, then the problem starts here: the Ether Type is not interpreted as Ether Type, but as length.
After remark in one of the answers, I tried to reverse the two byte ether type from 00 08 into 08 00 (MSB first), but that made the problems worse.
=== IPV4 header ===
- 45 00 5D 00
- 00 00 00 00
- FF 00 E0 0D
- 8A 84 77 44
- E0 2B 9C FB
Specification of the IPV4 header structure
DWORD 0

- bits 16..18 Flags; bits 19..31 offset: 0000
DWORD 2

- bits 16..31 Header Checksum 3552 (0DE0)
DWORD 3 and 4
Source IP: 138.132.119.68
Destination IP: 224.43.156.251
Bacause wireshark complains about checksum, I verify as follows:
Verify checksum:
Header: 0045 005D 0000 0000 00FF 0DE0 848A 4477 2BE0 FB9C
69 + 93 + 0 + 0 + 255 + 3552 + 33930 + 17527 + 11232 + 64412 = 131070 (01FFFE)
0001 + FFFE = FFFF
1's complement: 0000 (checksum ok)
This is what WireShark (version 2.4.4) makes of it:
The following seems normal:

Here comes the first problem: EtherType is interpreted as Length

Frame check sequence: 0x41414141 incorrect, should be 0xe19cae36
[FCS Status: Bad]
After the length, which I meant as an EtherType, comes a lot of padding, instead of interpretation of my 5 DWORDs.
The link to the Ethernet Frame in wikipedia I showed says:
The EtherType field is two octets long and it can be used for two
different purposes. Values of 1500 and below mean that it is used to
indicate the size of the payload in octets, while values of 1536 and
above indicate that it is used as an EtherType, to indicate which
protocol is encapsulated in the payload of the frame.
My value if 0x0800 = 2048. This certainly is above 1536
For example, an EtherType value of 0x0800 signals that the frame
contains an IPv4 datagram.
If value 0x0800 the incorrect value? Or is my error somewhere else?
Looks like your ethertype has the wrong byte order. It should be:
