I've seen lots of pools send out transactions and it shows their pool name instead of just a long wallet address. I'm sure it's a simple geth console command but I can't seem to figure out which one it is. Probably namereg or something.
Are you referring to names on ethereum block explorers, like https://etherscan.io?
If so, it is not a command in geth. The name is configured by the owners of those block explorers. So your only option would be to send them an email and ask for your address to have a "pretty name"
I hope this helps!

First, thanks Hasura for incredible good product! I love it.
I have issue with derive action with Hasura Console. My use case:
I enable anonymous role for subscribe function (everybody can send email to subscribe)
I have configured permission on my subscribe table, everything is fine.
I want to validate the user input on server side, for example, validate email format. I have followed by this guide about derive action. I found no mistake here.
But I got the error "Type query_root must define one or more fields." when I hit "Derive action" at the first time.
According to this question, as I understand, I need to have object type for root query.
Of course, I will have object type for root query eventually. I can work around by giving some dummy queries for anonymous role. But I do not like that cheat anyway.
Any idea on that? Any help will be highly appreciated.
Edited:

Hasura 1.3.2

I would like to host my webapp on Firebase, since I'm using their services and functionalities since a long time (before Firebase was inside Google and since its static hosting service was named Divshot... ).
But I've got a demo domain from Freenom (.tk domain) and I was wondering how to connect this with firebase:
I can set only this paramater relative to TXT record:
dns management
so where should I define the parameters needed
google-site-verification=...
?
Thank You to all!
PS: I've already seen
Firebase hosting custom domain error
and related
firebase-talk Dqmz9Iuio54
and
and the question: how-can-i-verify-my-custom-domain-using-domains-google-com/39020649#39020649
but none of them seems to respond to my problem...
PS: I've come here from firebase support page where StackOverflow is the first choice.
Thank you!
Leave the "Name" field blank and fill "Target" with the google-site-verification=... value. Once you've done so, things should go through. One way to check is to run:
dig yourdomain.tk TXT
If you've done it correctly, you should receive back the google-site-verification=... value. It may take some time to propagate before it starts showing up.
DNS registrar / records host: delete TXT records pointing to
firebase.
firebase console: delete the custom domain.
firebase console: add custom domain.
copy the two TXT records from firebase to DNS host
DNS record host should include two entries with one yourdomain.tk and www.yourdomain.tk
Once the yourdomain.tk is added it'll show as empty and other entry will be shown as www.
The copy the two given A records to Freenom DNS records.
There will be 4 A records two for yourdomain.tk and two for www.yourdomain.tk.
Wait 24-48 hours to see if the changes work.
If it doesn't work, contact firebase support from the console; be sure to take screen shots of the DNS records and the firebase console. These will help the firebase support team to troubleshoot the problem.
Mean while you can check for the dns propagation by using below tutorial
The Firebase Hosting servers run what is essentially this command for verifying the TXT records for your domain:
dig -t txt +noall +answer yourdomain.tk
If you immediately run this command right now, you might not get results. If the Firebase servers are seeing the same in their DNS query, they will not be able to continue.
That means that either you didn't save/apply your changes yet, or they haven't propagated everywhere yet. The longer it takes for the changes to show up, the more likely it becomes that you still need to take some action at your DNS provider
I am trying to configure my asterisk to regsiter every user who tries to connect to it, and allow it to establish calls. I have read that I should set "allowguest = yes" in sip.conf.
What about the dialplan in extensions.conf ? What should I add so that all my users could make and recieve calls ? (this is my first questions).
I would go even more precise about the users : is it possible to allow only guests from one precise domain ? If yes please help find how to do it, I will be very thankful.
Guest calls will go to default context which is in general section of sip.conf
[general]
context=some_restricted_access
About dialplan for calls - you need read some book for beginner or install freepbx/other web which do dialplan for you.
No, you can't allow guests from domain. But you can try play with realm= setting or allow access from one ip by using ip-authentification.
I run a Wordpress site for my company, and lately we've been getting comment spam to the point of triggering a lockout for 20+ hours at a time. I can't log in, nor can any of my coworkers. We whitelisted our IP address, but still keep getting locked out.
Is this a common occurrence? I can't imagine I'm the only person to run into this specific issue, but Google has as of yet been unhelpful...
I took it up with my managed hosting provider - WPEngine - who told me that I needed to whitelist our office IP (done, didn't help) and, if we get locked out, run a SQL query on our production database:
SELECT option_value AS row_count
FROM wp_options
WHERE option_name = "limit_login_lockouts"
Which, y'know, doesn't actually do anything, just tells me that, if I'm reading this right, we've gotten something like 1.4 billion attempts to log in from an IP address that coincides with the Linode datacenter WPEngine has us sitting in.
Long-winded, sorry, but my question is twofold: what should I do to clear this up temporarily to let me log in, and what do you do/have you done to avoid this issue?
Thanks.
Have you tried using another IP (another location) rather than your offices? If you have cPanel access you might wanna check your access logs and look for any fishy IPs. Also check to see if your IP is on IP "Deny list".
Hope this helps
I am writing an web-application which needs to receive e-mail messages to users' internal email addresses, let administrators approve them, and then forward to corresponding user's external mailbox.
I have installed and configured postfix for message receiving task. It uses virtual e-mail addresses, and my existing database where user email addresses are stored. Local email storage is maildir and I use postfix's virtual MDA.
Basically, I would like to execute a script every time a new message is received, and for which user (maildir message id would be very helpful too). Then I could read the message from python code (python had a module for maildir messageboxes) and insert it in database.
I can think of three ways to do this:
iterate user maildirs and check
if there are any new messages, but it would be ineffective for large number of users.
use dbmail and then check if there are any new messages in database (this would be quicker, but I'd have to configure everything from scratch). Besides, existing user data tables cannot be used.
write a wrapper around maildrop/virtual to save message in db and in maildir as well, but I'd need a way to check if received message is valid and successfully saved by the real MDA.
Any suggestions appreciated!
In the /etc/aliases file you can specifiy a program which gets executed everytime a user recieves a mail. This program gets the mail on stdin. So you dont have to poll and your program gets run instantly.
In response to my own question, I used postfix content_filter with X flag set in pipe and process receiving address and message manually. Since I didn't need to access messages in maildir, this approach works fine for me.
