            Shell prompt does not shows on socket
            Asked 2021-Dec-05 at 10:35

            I want to establish a remote shell over tcp.

            I already got it to work, but there's a small issue: The prompt does not shows up on client side.

            If my client input echo hi, it well prints hi on stdout (client side), and the shell process remains open until he hits ctrl-D or chooses to exit whatever way.

            After some basic investigation, I figured out that bash prints its prompt on stderr (e.g. bash 2>/dev/null will not show any prompt on any terminal).

            This may be a hint but before I call execve in the shell process, I do my redirections from my server to my client connection fd this way:



            Answered 2021-Dec-05 at 10:35

            man bash:

            An interactive shell is one started without non-option arguments (unless -s is specified) and without the -c option whose standard input and error are both connected to terminals (as determined by isatty(3)), or one started with the -i option.

            A non-interactive shell normally won't print the prompt at all.



            calico-kube-controllers and calico-node are not ready (CrashLoopBackOff)
            Asked 2021-Sep-21 at 18:18

            I deployed a brand new k8s cluster using kubespray, everything works fine but all of the calico related pods are not ready. And after many hours of debugging I couldn't find the reason why calico pods are crashing. I even disabled/stopped the entire firewalld service but nothing changed.

            One other important thing is that calicoctl node status output is not stable and every time gets called show something different:

            Fortunately increasing timeoutSeconds for both livenessProbe & readinessProbe from 1 to 60 fixes the issue.



            Reverse proxy to another machine

            Explanation of what I am trying to do:

            I have 2 servers on the ip (docker reverse proxy) and (other services). I want 10 to redirect requests to 20 (many of these requests are with SSL).

            the nginx config there is reverse proxying to itself on port 80. If you want to reverse proxy to one of the other containers change lacalhost to whatever service name you gave the container. eg http://nginx_external:80

            If that does not work, try ammending your config to being something along the lines of:



            Regex Optional Lookahead with non-greedy
            Asked 2021-Jun-30 at 17:25

            I am currently trying to create a regex that is able to parse the following lines of logs:



            Answered 2021-Jun-30 at 17:13

            In this pattern \[[^\[\|]*\|[^\]]*\].* the .* at the end will match the rest of the line

            In this pattern \[[^\[\|]*\|[^\]]*\](.*?)(?=\[[^\[\|]*\|[^\]]*\]) you match the beginning of the log with the square brackets and then capture as least as possible characters until the positive lookahead assertion at the end is true.

            If the assertion is not true, the .*? non greedy part will suffice with matching 0 chars.

            What you could do is add an alternation | which states matches as least as possible chars until you either encounter another log start, or the end of the string.



            Updating kubernetes with kOps causes calico-node to fail with "BIRD is not ready: BGP not established"
            Asked 2021-Jan-10 at 09:45

            Let me preface this by saying this is running on a production cluster, so any 'destructive' solution that will cause downtime will not be an option (unless absolutely necessary).

            My environment

            I have a Kubernetes cluster (11 nodes, 3 of which are master nodes) running v1.13.1 on AWS. This cluster was created via kOps like so:

            Issues with OIDC while performing DNS Flip

            We recently performed a DNS Flip on a Rails application integration environment.

            Config or operational data from pyang confd
            Asked 2020-Jun-08 at 07:35

            Can we determine if it is a configuration or operational data model from the pyang model in confD, If I do not have permission to read the actual yang file Eg:



            Answered 2020-Jun-08 at 07:35

            As mentioned in FAQ A data-model defines the configuration (R-W) data, operational (R-O) data, and administrative actions that are accessible for a management system and maintained by the device.

            From Pyang file, rw indicates configuration data while ro indicate read/operational data

            C sockets upload and download a file in same request
            Asked 2020-Feb-05 at 15:45

            I am trying to receive a file thats uploaded by the client and in the same socket descriptor send a command download a file from the server in chunks

            The issue is if the socket descriptors are in different files things work flawlessly but if its the same file client and server programs are hanging up

            The second problem is even if its in different files I could not send the client a message saying that the file is received

            Can anyone please advice

            PS- to run the program might need to create a file named fileclient.txt and enter some random text




            Answered 2020-Feb-05 at 15:45

            You seem to expect that the string "DOWN" is recognized by the server and a download is triggered. This is very unlikely to happen.

            TCP connections do not take care about granularity of data that is put into the socket. If you put in 1000 bytes at once on one side, it is not guaranteed that those 1000 bytes are received in one go. You may receive either 1000 bytes or 500 + 500 bytes of 999 + 1 bytes.

            Same applies if you send with multiple requests. Putting in 1000+4 bytes could result in receiving 1000+4 or 1004 or 500+500+4 bytes or any other combination.

            This means that you cannot simply rely on receiving all bytes for the file upload first and then wait for another command ("DOWN") or another file. It is very likely that you will receive the "DOWN" together with the last bytes of the uploaded file and simply store them into the output file.

            The same applies for download direction. The client would not be able to distinguish a file download from an "upload done" notification.

            To solve your problem you need to introduce more logic into your protocol. There are various options:

            • Use 1 socket and 1 connection for each operation or each direction. No need to mix everything into a single socket.
            • Add some indication about file upload, e.g. total length to be expected in front of your upload.
            • Use 1 socket for control flow and multiple others for data transfer (see FTP for details)
