How to set proxy config for DSU system inventory

I'm trying to run dsu inventory but it is hanging:

Fetching invcol_LN64_C1KC7_24_12_00_240_A00.BIN ...
Getting System Inventory ...

The problem is that /opt/dell/invcol_LN64_C1KC7_24_12_00_240_A00.BIN.6UBNArTBas/BIOS_16G/Pluggable
IE.bin is trying to connect to the BMC USBNIC at https://169.254.1.1:443 via our proxy.  I've tried to prevent this by setting various no_proxy variables:

no_proxy=127.0.0.0/8,::1,localhost,10.0.0.0/8,172.16.0.0/12,192.168.0.0/16,.nwra.com,169.254.0.0/16
NO_PROXY=127.0.0.0/8,::1,localhost,10.0.0.0/8,172.16.0.0/12,192.168.0.0/16,.nwra.com,169.254.0.0/16

But that does not appear to be helping - it's still trying to go through the proxy.  How can I prevent it from trying to connect to the BMC via the proxy?  In some sense it seems like PluggableIE.bin should be completely ignoring proxy settings when trying to contact the local BMC as that will surely never work.

Hello, thanks for choosing Dell and welcome to our community.

Dell System Update Version 2.1.1.0 User’s Guide | Dell 日本

system-update | Dell System Update Version 2.1.1.0 User’s Guide | proxy

 

Following are the limitations for proxy:

  • Ensure to use --source-type=REPOSITORY for Linux operating system.
  • YUM repository is not supported in proxy.
  • When configuring the system proxy through network settings for the Linux operating system and using system proxy information, ensure to update the environment variables echo $HTTP_PROXY or echo $HTTPS_PROXY.
  • Configure a system-wide proxy for remote servers.

 Hope this helps. 

 

Resepctully,

@DELL-Young E​ So, that's nice general information about proxies, but it doesn't help with this specific case, and it seems a bit presumptuous to mark it as the accepted answer before getting any response.

I don't have any problem setting the proxy via http_proxy/https_proxy.  The problem is that this inventory collection process:

root      200995  200993  0 08:51 pts/0    00:00:00 bash /usr/libexec/dell_dup/invcol_LN64_C1KC7_24_12_00_240_A00.BIN -outc=/usr/libexec/dell_dup/inv.xml -logc=/usr/libexec/dell_dup/icLog.txt
root      201132  200995  0 08:51 pts/0    00:00:00 ./invcol -bdir=/root -outc=/usr/libexec/dell_dup/inv.xml -logc=/usr/libexec/dell_dup/icLog.txt
root      202902  201132  0 08:51 pts/0    00:00:00 sh -c ./PluggableIE.bin -i 2>/dev/null

[2024-12-12T08:58:23] :         CMTCurlCommon.cpp:  162: GET: https://169.254.1.1:443/redfish/v1/UpdateService

Attempts to contact the BMC NIC at 169.254.1.1 via the proxy, despite my adding that IP range to the no_proxy environment variable.  Again, it seems that any attempt to contact the local BMC should never use the proxy since that will never work.

--source-type=REPOSITORY does not appear to have any effect.

Okay, reading the documentation more closely led me to this command:

env -u https_proxy dsu --proxy=$https_proxy

this appears to use the proxy where necessary, but not pass it on to the inventory collection stage.  So setting the https_proxy environment variable is actually breaking dsu and it's better to use the command line option.  At least until this gets fixed properly.

Hi, we actually hit the same issue with the new DSU. I managed to get around it with this command

https_proxy=proxy_server_ip:3128 no_proxy=169.254.1.1 dsu --inventory
