QUESTION
I have integrated IdentityServer4 in spring Boot project.
I want to know how to add code_verifier to call "/connect/token" of IdentityServer?
I receive code in the redirecturl as follows,
I construct a resttemplate in my project to call "/connect/token" as per
POST /connect/token CONTENT-TYPE application/x-www-form-urlencoded
...ANSWER
Answered 2022-Feb-09 at 10:17I finally resolved this issue. But still not satisfied with the methodology. Yet, it works gracefully. What I expected from OAuth2AuthorizationRequestResolver that the request to get the jwt token gets created internally and I should be unaware of the random string generated as code_challenge(to implement PKCE).
I still request to share if somebody has a working example of authenticating and getting token by just providing required confs without me implementing and overriding OAuth2AuthorizationRequestResolver. So, here i go
To implement OAuth2AuthorizationRequestResolver please follow https://developer.okta.com/blog/2020/01/23/pkce-oauth2-spring-boot
then in method addPkceParameters
QUESTION
I'm attempting to make an ASP.NET Core 5.0 application using Kestrel, and I would like to auto port forward the server's port.
PackageI'm currently using the OpenNat.Core package. I have also tried the regular OpenNat and the same issue arises.
When port forwarding, the program says it has mapped everything correctly and the map even shows when listing all mapped ports on my router. Yet, when I attempt to view its status via CanYouSeeMe.org it returns a timed out error, and I am unable to access the server outside the network.
What I've Tried- I thought that the port mapping might have been opening after the server started, so I manually opened the port and then restarted the Kestrel server.
- I made sure that my router supported UPnP
- I also have a Synology NAS that I port forward from, and it works just fine.
- I had a friend use ZenMap to check the port.
- The port shows that it's filtered but not open (and no service was specified).

QUESTION
I want to build a port map tool in python from scratch. Basically it is a TCP proxy that transits all the traffic between the client and the objective service or application.
Specifically, For every connection I create two sockets who are responsible to communicate to the client and objective service respectively. To implement IO-multiplexing feature, I use module selectors to monitor the EVENT_READ and EVENT_WRITE event on these two sockets. However I find that the sockets are always writable so that the main loop doesn't block at all. Is it normal? My code is as follows:
ANSWER
Answered 2020-May-28 at 13:12A socket is normally writable until the system buffer is full. That is the reason why many simple select multiplexed system only considere the read part and assume that they will be able to write or accept the possibility of being blocked if they are not.
If you want to be super safe and ensure that you will be able to write, you should ignore EVENT_WRITE unless you are ready to write something. But to prevent your code to exhaust the local memory buffer, the relay should stop reading (also ignore EVENT_READ) if the other channel cannot write.

QUESTION
Can somebody help me troubleshoot setting up NFS share between two Centos 7 machines?
- https://www.howtoforge.com/nfs-server-and-client-on-centos-7
- https://www.unixmen.com/setting-nfs-server-client-centos-7/
I have configured the firewall and the server is working fine, I can mount the shared folder from the different (third) Centos 7 machine.
However, on this other client machine, let's call it 111.111.111.111 I cannot mount:
ANSWER
Answered 2020-Apr-21 at 13:33Here's the best workbook I've found for troubleshooting NFS connections: https://docs.oracle.com/cd/E23824_01/html/821-1454/rfsadmin-215.html
Follow those instructions slowly and carefully and they should turn up the problem. That doc is a good example of a step-by-step troubleshooting where you check all the connectivity prerequisites before checking the actual service you're trying to test.
Here's some additional info that may help:
Your network sniff output is simple - the server isn't responding to you on the NFS TCP port. I hope the server's IP isn't really 255.255.255.255, since that's a broadcast address and is unlikely to work reliably.
You may have dropped all the firewalls, but the NFS server has its own permissions control, in the /etc/exports file according to the HowToForge link that you were following. You need to specify ALL the clients, not just a single IP address. You can also use a network range that includes all the clients. "man 5 exports" should tell you more about how to edit this file. Please DON'T put in "*" to match all IP addresses as suggested in the HowToForge link, that is generally a bad idea.
portmapper might be using the TCP wrappers permissions files - /etc/hosts.deny and /etc/hosts.allow - see "man 5 hosts_access" for the format of these files. look in the syslog files for the IP address of the client to see if there are any messages about that client.
Even though you think you turned the firewall off, run "iptables -vL" to see if there are any rules you overlooked and whether they have any hits.
If you have custom MTU settings on any of the machines (for example, on storage-specific LANs people often set up jumbo packets) make sure that there are no mismatches. This is unlikely to happen on a home network.
Your sniff shows the client is attempting to connect via TCP to the nfs port 2048, it's possible the client is configured for NFSv4 and the server is configured for NFSv3 or lower. You might see this with the rpcinfo command, since it shows the versions of NFS supported by the server.
QUESTION
My application listens to both HTTP and HTTPS ports. HTTP channel is available only for several clients, all other must be redirected to the secure channel (HTTPS) when trying to access the insecure one.
The problem is the HTTPS port for the redirection, for good reasons I'm starting the connector by myself, based on the application properties. The configuration is unknown to the default port-mapping implementation PortMapperImpl, so it returns always 443 or 8443 ignoring the actual ports the application is listening on.
So far I have find this; it works, but it looks really ugly:

Install portmapper
UPnP PortMapper requires JRE 11 (Java Runtime Environment) or later. I recommend you download OpenJDK 11 JRE from AdoptOpenJDK. For Windows please choose the .msi installer which will set the environment variable JAVA_HOME and add java to the PATH.
