NAME

bgplgshlooking glass shell for the OpenBSD Border Gateway Protocol daemon

SYNOPSIS

bgplgsh

DESCRIPTION

The bgplgsh program is a looking glass shell for the bgpd(8) Border Gateway Protocol daemon. The looking glass will provide a simple command line interface with read-only access to a restricted set of bgpd(8) and system status information, which is typically used on route servers by Internet Service Providers (ISPs) and Internet eXchange points (IXs).
It requires three steps to enable the looking glass shell:
  1. Add bgplgsh as a valid login shell. See shells(5) for more information.
    # echo /usr/bin/bgplgsh >> /etc/shells
        
  2. Create a new user for restricted looking glass access. See adduser(8) for more information about system user management.
    # adduser -shell /usr/bin/bgplgsh -batch bgplg 
    # passwd bgplg
        
  3. Start the Border Gateway Protocol daemon with a second, restricted, control socket. See bgpd.conf(5) and bgplg(8) for more information.
    For example, add the following to /etc/bgpd.conf to have bgpd(8) open a second, restricted, control socket:
    socket "/var/www/run/bgpd.rsock" restricted

FILES

/var/www/run/bgpd.rsock
Position of the second, restricted, control socket of bgpd(8).

AUTHORS

The bgplgsh program was written by Reyk Floeter <reyk@openbsd.org>.

CAVEATS

To prevent commands from running endlessly, bgplgsh will kill the corresponding processes after a hard limit of 60 seconds. For example, this can take effect when using traceroute(8) with blackholed or bad routes.
