GIT upload

If you attempt to push a large set of changes to a Git repository with HTTP or HTTPS, you may get an error message such as error: RPC failed; result=22, HTTP code = 411. This is caused by a Git configuration default which limits certain HTTP operations to 1 megabyte. To change this limit run within your local repository

git config http.postBuffer *bytes*where bytes is the maximum number of bytes permitted. For exmaple:

git config http.postBuffer 524288000

Self-compiled sniffer from Git sources

If you use a self-compiled sniffer from Git (required for Napatech cards, which are not supported in static binaries provided by voipmonitor.org), configure the sniffer's /etc/voipmonitor.conf with:

upgrade_by_git = yes
git_folder = /usr/src/voipmonitor-git

When you click UPGRADE in the GUI, the sniffer will perform these steps:

git pull
configure
make clean
make
service voipmonitor stop
make install
service voipmonitor start

If you need special parameters for configure (e.g., for Napatech support), add them with the configure_param option:

configure_param = --with-dpdk-include=/opt/napatech3/include --with-dpdk-lib=/opt/napatech3/lib

= Error: "You are not currently on a branch"

If the git upgrade fails with the error fatal: You are not currently on a branch., your Git repository is in a detached HEAD state. This typically happens if a specific commit hash or tag was previously checked out, or if a previous upgrade attempt was interrupted.

The upgrade_by_git mechanism relies on git pull to update the source code, which only works when you are actively tracking a branch (e.g., master or develop).

Solution:

1. Navigate to your Git source directory:

cd $(grep "^git_folder" /etc/voipmonitor.conf | awk '{print $2}')
# Or directly if you know the path:
cd /usr/src/voipmonitor-git

2. Check the current Git status:

git status

Expected output should show: HEAD detached at <commit-hash>

3. Switch to the appropriate branch:

  For standard production (stable) installations:

git checkout master

  For Napatech cards or development builds:

git checkout develop

4. Update to the latest code:

git pull

5. Verify you are on the correct branch:

git branch

Expected output should show an asterisk (*) next to master or develop.

6. Retry the upgrade process from the GUI or command line.

Note: The Napatech documentation and official instructions refer to the branch as develop (NOT "development"). Use the exact branch name to avoid errors.
