Curl Download File Name [UPD]
Lorraine Karmazyn
I'm new at PowerShell, maybe I'm doing a mistake when coding those lines, but do you have any suggestion how to deal with?Do you think there is a better Command Prompt/CLI than PowerShell to use curl?
I already found a workaround by creating a temporary symlink to the original file and pass that to curl. However the problem is that the filename that curl sends to the server is the filename of the symlink, not the original file.
since Kubernetes v1.10 kubectl port-forward allows using resource name, such as a service name, to select a matching pod to port forward With this connection in place you can use your local workstation to debug the application that is running in the pod.
curl doesn't support what you're trying to do directly, you can either pass it a new filename where to store the results, or let it determine the filename (and possibly extension) from the HTTP headers.
So you should do this in two steps. I recommend letting curl determine the name of the file, therefore downloading 2d9ec0354908e055acf372.zip, which you can then rename to file-a-of-n.zip, preserving the ".zip" part of it.
To make your job easier, create a temporary directory in which to work, and then create subdirectories for the a-of-n's and download the file into that subdirectory, that way you'll have a single file to handle in each subdirectory (easy to tell which one you need to process), which you can then move and rename, while preserving the extension.
I know this is because certificate is specific to domain name and I am trying to send a request using the IP address. But as I said this is a limitation that I have (rackspace load balancer health monitoring).
i have a curl error 60 (SSL: no alternative certificate subject name matches target host name...) I saw in a previous topic that it would be fixed in curl 7.81, but I'm running with 8.2.1... I tried to install a previous version (following this), but it gave me an error -with-openssl was given, but OpenSSL wasn't found. I also tried installing curl 8.1.2 through snap, same error 60.Does anyone have an idea ?(i have Pphp 8.2.10-2ubuntu1 and ubuntu 23.10)
You're using some kind of PowerShell script that tries to emulate curl but doesn't support all options. This question has come up before and I believe there was a way to get PowerShell to send a DELETE request instead.
The version of curl installed on the remote host is affected by a heap based buffer overflow in the SOCKS5 proxy handshake. When curl is asked to pass along the hostname to the SOCKS5 proxy to allow that to resolve the address instead of it getting done by curl itself, the maximum length that hostname can be is 255 bytes. If the hostname is detected to be longer than 255 bytes, curl switches to local name resolving and instead passes on the resolved address only to the proxy. Due to a bug, the local variable that means 'let the host resolve the name' could get the wrong value during a slow SOCKS5 handshake, and contrary to the intention, copy the too long hostname to the target buffer instead of copying just the resolved address there.
Hello,
I'm curious if it was helpful and if it returned what you might have expected and if a manual double check confirmed it was expected?
I'm sure it could be refined but OK as a starting point?
The time it goes back in the journals is is only 15 minutes by default, so it would have only returned data for processes that loaded libcurl that wasn't 8.4 in the last 15 minutes. The "time" > epoch could be used as needed.
Thanks
libcurl is a free, client-side URL transfer library with support for a wide range of protocols. libcurl is portable, thread-safe, feature rich, and well supported on virtually any platform. It is probably the most popular C-based, multi-platform file transfer library in use.
The easiest way to authenticate with Oracle Eloqua's APIs is to use basic authentication which uses your Eloqua company name, user name, and password to authenticate. To use basic authentication, use the cURL --user option followed by your company name and user name as the value. cURL will then prompt you for your password.
This is pretty straight forward. The reason for the --insecure/-k flag is that you are using a self-signed certificate which curl is unable to validate, since it does not know anything about the root CA that was used to sign it.
When you connect with curl to the HTTP(S) port of Elasticsearch, A TLS handshake is initiated. This basically means that Elasticsearch will send the configured TLS certificate to curl. Now curl needs to validate this certificate. It does so by checking if the certificate was signed by any known and trusted root CA. Since the root CA you are using is self-generated, this will fail, unless you make the root CA known to curl with the switch I posted. Curl does not send the root CA to Elasticsearch. It uses it to validate the cert it receives from Elasticsearch.
That makes sense thanks! So if I wanted another application to communicate with elasticsearch with SG enabled, I would need to have the root-ca.pem file in that cert and also have it added to that applications keystore since it would be sending HTTP requests and I would not be able to pass the cert in through a flag like a curl?
The error you are seeing is because your node certificate does not contain a valid hostname or IP address. It seems when omitting the --insecure flag, curl validates the certificate against the root CA (this seems to work in your case) and then validates the hostname in the certificate.
The data section of the query result consists of- headStats: This provides the following data about the head block of the TSDB: - numSeries: The number of series. - chunkCount: The number of chunks. - minTime: The current minimum timestamp in milliseconds. - maxTime: The current maximum timestamp in milliseconds.- seriesCountByMetricName: This will provide a list of metrics names and their series count.- labelValueCountByLabelName: This will provide a list of the label names and their value count.- memoryInBytesByLabelName This will provide a list of the label names and memory used in bytes. Memory usage is calculated by adding the length of all values for a given label name.- seriesCountByLabelPair This will provide a list of label value pairs and their series count.
Client URL (otherwise known as cURL or curl) was released in 1997 by Daniel Stenberg, who has diligently maintained the project since. It was originally created to automate the fetching of currency exchange rate for IRC users but has since become wider used for all forms of URL fetching. Since its inception, Daniel has continued to develop and add features to the project as it has become a backbone for other projects. Absolute hero.
Below is a simple curl command I ran from the terminal application on my MacBook. This one requests the homepage of Fastly.com and displays the full HTML. A caution that this is a noisy output that we will clean up later.
The flags I use on nearly every curl are -svo, which reads as silent mode (s), verbose (v), writing to a file (o), which I write to /dev/null. The full curl command is curl -svo /dev/null This allows me to focus on the detailed request without the distractions of a noisy response body. The headers have a nice little flag to show if they were sent or received, and the SSL negotiation is shown before the main request.
The current use of shows the URL being requested. Whichever hostname is used within the URL (e.g www.fastly.com) will be the value curl uses to request and verify the SSL certificate name. This is important in order to validate that TLS is working the way you expect it to, and that your site is secure with the certificate you expect. See the example below:
A typical web server can host multiple sites with different domain names, like blog.example.com or docs.example.com. While the sites might reside on the same system, the source code and/or the URL path could be different.
If we want to change the host header, we can pass this by explicitly defining the header within curl. Headers can be declared with either a --header or, for short, the -H flag. Then the value is encapsulated with quotations and the name of the header is defined. The curl command looks like this:
A sweet little benefit of using connect-to is that it allows you to skip explicitly defining the domain name you are looking to define DNS for as in resolve, as well as the port. So you will see ::151.101.185.57 or you could use ::target.host.fastly.com.
You should be able to ssh into any node in your cluster and use a tool such as curlto make queries against both IPs. Note that the containers are not using port 80 onthe node, nor are there any special NAT rules to route traffic to the pod. This meansyou can run multiple nginx pods on the same node all using the same containerPort,and access them from any other pod or node in your cluster using the assigned IPaddress for the pod. If you want to arrange for a specific port on the hostNode to be forwarded to backing Pods, you can - but the networking model shouldmean that you do not need to do so.
