Package: lsof
Version: 4.77.dfsg.1-3
Severity: normal
Using lsof -i, I cannot see the listening socket for postgrey.
Other services are shown as expected.
I run lsof as root, below is the output from my diagnostics so far.
The listening socket is definately open and accepting connections, it is fd
4 for the application, and an lsof -p for the proc shows errors accessing
fd/4 - readlink: Permission denied
Other perhaps relevant information, this is running on a user mode linux
guest system at bytemark.co.uk
