I've been trying to connect Huawei E3131 to my Raspberry pi.
So far I've installed ppp, usb_modeswitch and wvdial. Here is my wvdial.conf partially generated by wvdialconf and partially changed by myself:
[Dialer Defaults]
Modem = /dev/modem
Username = { }
Password = { }
Baud = 9600
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0
Init3 = ATX3
Carrier Check = no
Stupid Mode = 1
Modem Type = Analog Modem
ISDN = 0
Phone = *+88690xxxxxxx#
New PPPD = yes
In the end the output I get looks like that:
--> Initializing modem.
--> Sending: ATZ
ATZ
OK
--> Sending: ATQ0 V1 E1 S0=0
ATQ0 V1 E1 S0=0
OK
--> Sending: ATX3
ATX3
OK
--> Modem initialized.
--> Sending: ATDT*+88690xxxxxxx#
--> Waiting for carrier.
ATDT*+88690xxxxxxx#
NO CARRIER
--> No Carrier! Trying again.
--> Sending: ATDT*+88690xxxxxxx#
--> Waiting for carrier.
ATDT*+88690xxxxxxx#
NO CARRIER
--> No Carrier! Trying again.
The simcard in the dongle is from Chunghwa Telecom (Taiwan) if that is any help.
Ok, apparently you don't need to change the basic *99# to your phone number. So the final config file looks like
[Dialer Defaults]
Modem = /dev/modem
Username = { }
Password = { }
Baud = 9600
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0
Init3 = ATX3
Carrier Check = no
Stupid Mode = 1
Modem Type = Analog Modem
ISDN = 0
Phone = *99#
New PPPD = yes
run it with sudo for creation of ppp and everything works fine. Also you may run wvdialconf to generate the config file with suitable commands. However parameteres are not affected by it, except Baud. Hope someone will find it useful.

I am having trouble with EXIM passing e-mails. Domains are fictitious, but work better than using "example" to me.
Expected -> device -> relay#insurance.savewiththelizard.com -> payingtoomuch.com
Happening -> device -> relay#insurance.savewiththelizard.com -> vanishes
I found this Magento/exim emails not arriving, sent to and from own domain , but that nor the second answer has resolved my issue.
I have payingtoomuch.com e-mail hosted at GSuite. I have payingtoomuch.com website hosted at insurance.savewiththelizard.com .
When I use relay#insurance.savewiththelizard.com , it will pass to domains that are not hosted locally. Example: I am able to send an e-mail using relay#insurance.savewiththelizard.com to gmail.com, outlook.com, thiscompany.com, but I am not able to send e-mail to payingtoomuch.com . There are no errors when sending the e-mails.
On VestaCP, DNS nor MAIL are installed for payingtoomuch.com on insurance.savewiththelizard.com .

When im removing the relay host [ciphermail] from architecture i'm able to receive mail from external domain.
please suggest the answer.
It looks like you have enabled "Reject unverified recipient". The 450 error message reports that the recipient address cannot be verified. The default Postfix configuration for CipherMail is that Postfix will function as a store and forward server and no local mailboxes. However you have configured mydestination (indirectly by setting djigzo_mydestination) to locally handle mail for svitsolutions.in but you also configured relay_domains (indirectly by setting djigzo_relay_domains) to svitsolutions.in.
With the current config, email sent to svitsolutions.in will be handled by the local transport (which will then store the email locally). However in the default Postfix master.cf config, the local transport is disabled because in the default config, email should not be locally stored. Because the local transport is not available, the recipient verification will fail.
If you want to store email locally you should re-enable the local transport (see main.cf and master.cf) and make sure that a local user is available. If you do not want to store mail locally on the system but only act as a relaying server, set djigzo_mydestination and mydestination to an empty value.
I was developing an IoT application with a BBB and a Quectel GSM modem to send data over internet.
I configured the modem on the debian OS with PPP. Then with something similar to this example I stablished communication between my server and my client. Data was trivial, I send just a simple "Close!", and receive a simple "OK!". Sniffing the serial port, I was expecting something simpler, but here is what I saw:

I'm familiar with those AT commands, the "Close!" is there, and on the other side the "OK! is there too, but I didn't expect all those strange characters. I must say that I'm not very familiar with low level development for the TCP/IP network model, but I've always thought that sockets communication was the lowest layer (not counting physical layers).
What am I missing and where can I find more info related to this topic?
Thank you.
Trying to configure Exim mail server using this article. I can use this server inside my local network but when I try to use it from internet I taking some errors. Ports 10000-20000 translate to server machine. Everything I doing inside the docker image of CentOS 7. Host machine with CentOS 7 too.

When I try to connect from internet I got timeout error in mail client and empty logs in Exim. It's probably problem of work with router. How to make it works?
Ask me if you need more data. Thanks in advance.
You have your docker internal ports (for example 10025) mapped to standard smtp ports (for example 25), but you have exim listening on the standard ports instead of the mapped internal ports. Configure exim to listen on 10025, 10465, 10587 and see if the behavior changes.
It seems there's an issue with reverse DNS lookup according to this ancient post. Try disabling host_lookup and see if that works:
host_lookup = 0.0.0.0/0
If it does you'll have to fix your DNS settings to map the right domain to your host.

i have gone over my postconf and setup for the last 5 hours, i dont see anything wrong can someone point me in the correct direction? thanks a bunch!
fixed it,
used dig and ns to find the ips google uses to send mai, added those to mynetworks.
works like a charm finally after all day
