Aria2C Manual Command Line Run Getting Started Tutorial for Remote Download

Aria2C 手动命令行运行 进行远程下载的入门教程


When downloading at 2022-08-26, it was found that the SSL certificate of the AkamaiCDN used by the video source had expired, so the AriaNG panel could not be downloaded.



After some research, I found that the NG panel could not be adjusted and the certificate could not be verified, which may be related to the RPC connection method. Then I added check-certificate=false to the Config of Aria2C and I found that it still did not work.

This article introduces several solutions (including Aria2c command line, Wget command line) that cannot be downloaded from the remote server.

Aria2c command line

It should be noted that if you use the script to connect the Airang panel, then you must be running and using RPC. If you use the same default configuration file to start with the default port, it will report an error that the address is occupied.

The recommended workaround is to use the script to stop aria first. The default configuration file of aria2 installed by this script is in the /root/.aria2c directory

Specify the configuration file

 aria2c --conf-path="/root/.aria2c/aria2.conf"

Then I tried the command to add without checking the certificate, and found that it still had no effect.

 aria2c --conf-path="/root/.aria2c/aria2.conf" --check-certificate=false --disable-ipv6aria2c --conf-path="/root/.aria2c/aria2.conf"

Download command example

 aria2c "" -d "/root/downloads" -o "baidu.mp4" --check-certificate=false -x 1024 -s 64 -c

It should be noted that this command runs in the foreground by default and cannot be turned off directly like wget.

  • -d followed by the download directory folder
  • -o followed by the filename
  • -x followed by the maximum number of threads
  • -s followed by the current task thread number
  • –check-certificate=false does not check the certificate
  • -c is to resume the transfer from a breakpoint

For other parameters, please refer to the official documentation

Special case

Recently, there is a download link for video source network disk. I found that it cannot be downloaded normally in ariang, and wget and idm are normal.

The link format is start/xxx/x/xx/xxxx-720p.mp4 like this

Then I found that the IP at the beginning is the server ipv6, although it is an ASN with ipv4

At the same time, the airang panel is forced to disable ipv6. At least the one I use cannot enable ipv6. It may cause an error due to the inconsistency between the authorized IP and the download IP. In this case, you can consider disabling the server ipv6, or dns blocking ipv6 to solve it.

Then an error may be reported when downloading with aria2c (downloading directly with ariang has no progress)

[ERROR] CUID#7 – Download aborted. URI=

Exception: [] errorCode=22 URI=

-> [] errorCode=22 The response status is not successful. status=403

However, I changed https to http several times, and sometimes I can download it again. Of course, it is best to solve the problem of ipv6.

WGET command line

By default, wget will continue to download in the background, so you can turn it off directly. Of course, the commonly used wget is single-threaded, while IDM and Aria are multi-threaded downloads. If the other party’s speed limit or network speed is poor, the single-threaded speed may be very impressive.

Refer to the download command

 wget -O "/root/downloads/baidu.mp4" "" --no-check-certificate -c -T 30 -t 5 -d --user-agent="Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/ Safari/537.36"
  • -O followed by the file name in the path (usually the file name of the absolute path is used)
  • –no-check-certificate do not check certificates
  • -c resume the upload from a breakpoint
  • -T followed by timeout wait time
  • -t followed by the number of retries
  • -d, –debug print debug output
  • –user-agent followed by UA

  • http-proxy=
  • ftp-proxy=

  • –proxy-user=USER set proxy user
  • –proxy-passwd=PASS set proxy password

Last parameter side, use –proxy=on/off to use or not use proxy
