[i am trying to enter currency symbol for hardhat network in my metmask connection.i have surfed a lot but couldnt find one.i have entered network name,chain id,rpc url correctly, just need to find out the currency symbol][1]
You can use any letter prefix with ETH e.g hardhatETH or ETH itself

hostapd configuration for WEP network
I want to create fake access point in WEP mode using hostapd. I found some configuration samples like this: interface=wlan0 driver=nl80211 ssid=myAp hw_mode=g channel=1 macaddr_acl=0 auth_algs=3 ignore_broadcast_ssid=0 wep_default_key=1 wep_key1="abcde" wep_key_len_broadcast="5" wep_key_len_unicast="5" wep_rekey_period=300 It created the access point in WEP mode properly. But when I attempted to connect to this fake access point, it remains on authentication and can't connect to that. any helps?
The wep_key1 property is a HEX string. See here what makes a valid WEP key: https://www.speedguide.net/faq/what-is-a-valid-wep-key-110 wep_key1=abcde will be interpreted as 5 HEX characters instead of 5 ASCII characters, and you need 10 HEX characters. Therefore, a valid key would have double the length: wep_key1=abcdeabcde. As the other answer said, you should also remove the quotes. Edit: You should probably also remove your auth_algs line. For me, this setup works: interface=wlan0 driver=nl80211 ssid=myAp hw_mode=g channel=1 ignore_broadcast_ssid=0 wep_default_key=1 wep_key1=abcdeabcde wep_key_len_broadcast=5 wep_key_len_unicast=5 wep_rekey_period=300
Only thing I can think of is removing the quotes from wep_key1. I found this on the raspbian guide to setup a bridge: https://www.raspberrypi.org/documentation/configuration/wireless/access-point.md#internet-sharing
Reverse Phone Number Lookup Without Country Code
I have been using googles libphonenumber to perform validation of US phone numbers. Now I am needing international support for all countries. Is it possible to reverse lookup a phone numbers country code using libphonenumber? Say the DB has saved UK number +448456779463. Is it possible to libphonenumber to detect if that number is UK? It appears I can only check the validity of the number provided I know its country of origin first. But what to do if you have numbers and don't know its country of origin?
Twilio's Lookup tool can likely be of some help here. It will return a country code based upon number input alone and you can retrieve additional information about a phone via the API. https://www.twilio.com/docs/api/lookups [Disclosure: I work for Twilio]
You can do it using libphonenumber. Following is example in python import phonenumbers number = "+44XXXXXXXX" obj = phonenumbers.parse(number) # get line type phonenumbers.number_type(obj) # validate phone phonenumbers.is_valid_number(obj) # validate phone for region phonenumbers.is_valid_number_for_region(obj, "GB") # get country name from phonenumbers.geocoder import country_name_for_number country_name_for_number(obj, "en") I think following is what you looking exactly, from phonenumbers.geocoder import region_code_for_number phonenumbers.is_valid_for_region(obj, region_code_for_number(obj))
cryptocoin address generation
Recently have been looking at crypto currencies, mostly Bitcoin and Dogecoin. I'm using this source for my project. I've got Bitcoin to work perfectly, and since the Bitcoin gem did not have native support for Dogecoin I had to self-implement it. Also noticed that another githubber had opened tried to implement dogecoin support, which as of now did not generating address correctly. The problem seems to be in this particular line. (corresponding to the format of the crypto address) :address_version => "30" :address_version = PUBKEY_ADDRESS in base58.h base58.h PUBKEY_ADRESS contains value 30. Specifying this particular number will give address beginning with letter 'L' (litecoin address), where Dogecoin requires 'D'. Does this have anything to do with Doge using scrypt, I have no technical expertise in this field. How do I go about generating dogecoin pubkey/private key pair?
30 in decimal will give you a address begins with a letter D 30 in hexadecimal (48 in decimal) will give you a address begins with letter L I think that bitcoin-ruby first changes PUBKEY_ADDRESS from hexa to decimal so :address_version should be 1E (30 in decimal)
validating ip address in datastage
I have a source file that contains two fields: IP_ADDRESS and USER_NAME. I want to check whether the IP address is correct or not before loading it to the datawarehouse using DATASTAGE. How do I do this?
I was browsing Stack Overflow and think I might have a solution to your question. If you create a job to grab all of the IP_ADDRESS's from the file and send them to a BASIC transformer (search for BASIC transformer in DataStage. It is NOT the one that is normally on the palette). From there, set the Stage Variables as 'SetUserStatus() and write out the column name to a peek stage (You don't need the output at all. The SetUserStatus is the important part). This will now allow you to pass up the Command Output (list of IP Addresses) to a Sequence. From the Sequence, start with the job you just created (BASIC transformer job) and link that to a User Variables Activity. In the User Variables Activity stage, Set the name to something like 'IP Address' and Expression as IP_ADDRESS.$UserStatus. You can then use a Loop to take that output that is now a List and send each individual IP Address to an Execute Stage with a Ping command to see if it returns a valid IP Address. If it does return a valid IP then have your job that writes the USER_NAME and IP_ADDRESS to do a 'Select' statement where the IP_ADDRESS = the valid IP_ADDRESS. For the ones that aren't valid, you can send them down a different path and have them write out to '.txt' file somewhere so you know which ones weren't valid. I'm sure you will need a few more steps in there but that should be the gist of it. Hope my quick stab at your issue helps.
Yes, you can use a transformer or a transformer and a filter to do that, depending on the version of Datastage you're using. If you're using PX, just encode the validation logic in a transformer stage, and then, on the output link set up a filter that doesn't allow the rows to pass forward if they didn't pass the validation logic.
Is it possible for me to check and see if a value is entered in for ipv4?
I have a requirement to ensure that a value is entered in a server for ipv4 ip address, subnet mask, default gateway, a value for DNS and a value for WINS. I don't necessarily need to check against those values to ensure they are correct since the correct values are pulled from a seperate internal website. I don't have any way to interface with it. So I just want to make sure it is completely entered and ipv6 is not being used. I can't seem to find anything to help me on this. I looked through the registry to see if I could find anything there to grab. No luck =/ Any suggestions?
Your question is unclear. It almost sounds like you want to read a value from an input field, but then you say something about the registry. You need to ask more clearly where you are looking for said information.
With that in mind, assuming you mean you want to figure out if the system has acquired an IP address, etc., then consider the following.
1) You can use the Run method and execute ipconfig /all and parse its results.
2) You can use netsh.exe and parse results. For example:
C:\> netsh interface ipv6 show address
IPv6 is not installed.
There is a lot of information that is able to be gained through this method.
3) You can look in the Registry.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkCards usually contains a list of numeric sub-keys. For example, on my system, there is HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkCards\9. This key contains values:
Description REG_SZ "Broadcom NetXtreme 57xx Gigabit Controller"
ServiceName REG_SZ "{A1167D26-ADE0-4CDB-B0C6-1F8C5CF9DF5B}"
Of course, that ServiceName GUID will differ. It is unique to each system, but for the following, I will use it in examples. You have to replace it by what your system has.
This points to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\{A1167D26-ADE0-4CDB-B0C6-1F8C5CF9DF5B}\Parameters\Tcpip where the following values are stored:

This should get you started. Presumably, you can search the registry for {A1167D26-ADE0-4CDB-B0C6-1F8C5CF9DF5B} for other interesting information relating to your network adapter. For example:
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Dhcp\Parameters\...
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\LanmanServer\Linkage\...
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\lanmanworkstation\Linkage\...
... and so on ...
Each of those locations is rich with cross-references and data about the network sub-system.
