I am trying to pass the IP address of the remote host to a shell script
out of xinetd on the telnet port. I have tried the following:
# /etc/hosts.allow
ALL: ALL: setenv VIRTUAL_IP_ADDR %A
#
service telnet
{
disable = no
flags = REUSE
socket_type = stream
wait = no
user = root
passenv = VIRTUAL_IP_ADDR
server = /usr/local/bin/foo.sh
log_type = SYSLOG daemon notice
log_on_success = PID EXIT DURATION
log_on_failure = PID
}
The problem isthat the variable isn't being passed to foo. The only way
I've gotten this to work is to replace login with foo with telnet itself
(i.e. in.telnetd -L /usr/local/bin/foo). Telnet seems to place this
information into the environment as REMOTEHOST (where is this
documented?!) , but performs VERY slowly.
Any suggestions on how to pass the remote IP address more directly?
