Sounds like this wasn't a bug in 2.0.16 (current rhel7 version), but is a bug in the proposed 2.1.5 rebase? In case there's no steps in the github issue. Write the steps here. Description of problem: "HttpProxy" configuration in /etc/waagent.conf doesn't work. The waagent connect to Azure Server directly. Version-Release number of selected component (if applicable): WALinuxAgent-2.1.5 (upstream, package by tester) RHEL Version: RHEL-7.3-20160729.1 How reproducible: 100% Steps to Reproduce: 1. Prepare a VM on Azure with squid installed. Prepare a RHEL7.3 VM on Azure. These 2 VMs are in the same Virtual Network. Make sure that the client VM can connect to the Internet through the squid proxy, such as: # wget -e "http_proxy=[squid VM private IP]:3128" http://www.baidu.com Can download index.html successfully. 2. Change HttpProxy configurations in /etc/waagent.conf at the client VM: HttpProxy.Host=[squid VM private IP] HttpProxy.Port=3128 3. restart waagent service # systemctl restart waagent 3. Catch packages at the squid VM and the client VM: #tcpdump -s 0 -A 'tcp[((tcp[12:1] & 0xf0) >> 2):4] = 0x47455420' Actual results: Client VM: Can catch packages sent by waagent. Squid VM: No packages come from client VM are catched. Expected results: Squid VM: Can capture upload blob packages at proxy. Additional info: 1. It works well in WALA-2.0.16. 2. The root cause is that the PUT block/page blob request doesn't use proxy(wire.py Line 390 and 410), which do use proxy in 2.0.16. Verify in WALA-2.2.0 RHEL-7.3-20161019.0. Can catch upload blob packages on the proxy machine. *** This bug has been marked as a duplicate of bug 1387783 *** |
