Forgive me if this is not the correct mailing list for this question (and if not, point me to the correct one, if possible).
I am running PPTP (poptop w/radiusclient) on the same RHEL Linux box as the freeradius server. Initially, all works well. But after some time (30-45 min?), the radius server quits responding, and I see this in the pptpd.log: Jun 16 14:32:35 time3 pppd[29588]: rc_send_server: no reply from RADIUS server localhost.localdomain:1812 Running radiusd in debug mode shows nothing coming in for this query, although the server shows to be listening: [r...@time3 raddb]# netstat -ua | grep rad udp 19260 0 *:radius *:* udp 0 0 *:radius-acct *:* When this is occurring, radtest also fails, as it never gets a response (just keep resending). I am running (sorry, I realize that is no longer supported, but that's RH's latest Freeradius RPM, thus what I am required to use): freeradius 1.1.3 freeradius-client 1.1.6 ppp 2.2.4 pptpd 1.3.4 My configs: # cat /etc/radiusclient/radiusclient.conf | grep -v '#' | grep -v '^$' auth_order radius login_tries 4 login_timeout 60 nologin /etc/nologin issue /etc/radiusclient/issue authserver localhost acctserver localhost servers /etc/radiusclient/servers dictionary /etc/radiusclient/dictionary login_radius /usr/sbin/login.radius seqfile /var/run/radius.seq mapfile /etc/radiusclient/port-id-map default_realm radius_timeout 10 radius_retries 3 login_local /bin/login # cat /etc/radiusclient/servers | grep -v '#' | grep -v '^$' localhost/localhost testing123 # cat /etc/pptpd.conf | grep -v '#' | grep -v '^$' ppp /usr/sbin/pppd option /etc/ppp/options.pptpd debug stimeout 5 logwtmp connections 63 localip 172.20.1.143 remoteip 172.20.2.128-191 # cat /etc/ppp/options.pptpd | grep -v '#' | grep -v '^$' name pptpd refuse-pap refuse-chap refuse-mschap require-mschap-v2 require-mppe-128 ms-dns 172.24.2.197 ms-dns 172.24.2.196 proxyarp debug dump lock nobsdcomp novj novjccomp nologfd plugin radius.so plugin radattr.so Thanks for any help or suggestions, John This message is confidential to Prodea Systems, Inc unless otherwise indicated or apparent from its nature.
