Hi Folks, I just joined the mailer so I apologize if this has been asked before. I just attempted to install FreeRadius 2.1.10 using the following steps: 1) Downloaded ftp://ftp.freeradius.org/pub/freeradius/freeradius-server-2.1.10.tar.gz 2) gunzip and untar 3) ./configure 4) make At this point make fails with the following error: /root/freeradius-server-2.1.10/libtool --mode=compile gcc -g -O2 -D_REENTRANT -D_POSIX_PTHREAD_SEMANTICS -Wall -D_GNU_SOURCE -DNDEBUG -I/root/freeradius-server-2.1.10/src -DHOSTINFO=\"x86_64-unknown-linux-gnu\" -DRADIUSD_VERSION=\"2.1.10\" -DOPENSSL_NO_KRB5 -c radconf2xml.c gcc -g -O2 -D_REENTRANT -D_POSIX_PTHREAD_SEMANTICS -Wall -D_GNU_SOURCE -DNDEBUG -I/root/freeradius-server-2.1.10/src -DHOSTINFO=\"x86_64-unknown-linux-gnu\" -DRADIUSD_VERSION=\"2.1.10\" -DOPENSSL_NO_KRB5 -c radconf2xml.c -fPIC -DPIC -o .libs/radconf2xml.o gcc -g -O2 -D_REENTRANT -D_POSIX_PTHREAD_SEMANTICS -Wall -D_GNU_SOURCE -DNDEBUG -I/root/freeradius-server-2.1.10/src -DHOSTINFO=\"x86_64-unknown-linux-gnu\" -DRADIUSD_VERSION=\"2.1.10\" -DOPENSSL_NO_KRB5 -c radconf2xml.c -o radconf2xml.o >/dev/null 2>&1 /root/freeradius-server-2.1.10/libtool --mode=link gcc -o radconf2xml radconf2xml.lo /root/freeradius-server-2.1.10/src/lib/libfreeradius-radius.la util.lo log.lo conffile.lo -lnsl -lresolv -lpthread gcc -o .libs/radconf2xml .libs/radconf2xml.o .libs/util.o .libs/log.o .libs/conffile.o /root/freeradius-server-2.1.10/src/lib/.libs/libfreeradius-radius.so -lnsl -lresolv -lpthread -Wl,--rpath -Wl,/usr/local/lib creating radconf2xml /root/freeradius-server-2.1.10/libtool --mode=compile gcc -g -O2 -D_REENTRANT -D_POSIX_PTHREAD_SEMANTICS -Wall -D_GNU_SOURCE -DNDEBUG -I/root/freeradius-server-2.1.10/src -DHOSTINFO=\"x86_64-unknown-linux-gnu\" -DRADIUSD_VERSION=\"2.1.10\" -DOPENSSL_NO_KRB5 -c radsniff.c gcc -g -O2 -D_REENTRANT -D_POSIX_PTHREAD_SEMANTICS -Wall -D_GNU_SOURCE -DNDEBUG -I/root/freeradius-server-2.1.10/src -DHOSTINFO=\"x86_64-unknown-linux-gnu\" -DRADIUSD_VERSION=\"2.1.10\" -DOPENSSL_NO_KRB5 -c radsniff.c -fPIC -DPIC -o .libs/radsniff.o radsniff.c: In function `got_packet': radsniff.c:231: warning: assignment discards qualifiers from pointer target type radsniff.c: In function `main': radsniff.c:467: warning: implicit declaration of function `pcap_fopen_offline' radsniff.c:467: warning: assignment makes pointer from integer without a cast radsniff.c:489: warning: implicit declaration of function `pcap_dump_fopen' radsniff.c:489: warning: assignment makes pointer from integer without a cast gcc -g -O2 -D_REENTRANT -D_POSIX_PTHREAD_SEMANTICS -Wall -D_GNU_SOURCE -DNDEBUG -I/root/freeradius-server-2.1.10/src -DHOSTINFO=\"x86_64-unknown-linux-gnu\" -DRADIUSD_VERSION=\"2.1.10\" -DOPENSSL_NO_KRB5 -c radsniff.c -o radsniff.o >/dev/null 2>&1 /root/freeradius-server-2.1.10/libtool --mode=link gcc -o radsniff radsniff.lo /root/freeradius-server-2.1.10/src/lib/libfreeradius-radius.la -lnsl -lresolv -lpthread -lpcap gcc -o .libs/radsniff .libs/radsniff.o /root/freeradius-server-2.1.10/src/lib/.libs/libfreeradius-radius.so -lnsl -lresolv -lpthread -lpcap -Wl,--rpath -Wl,/usr/local/lib .libs/radsniff.o(.text+0xd13): In function `main': /root/freeradius-server-2.1.10/src/main/radsniff.c:489: undefined reference to `pcap_dump_fopen' .libs/radsniff.o(.text+0xdb3):/root/freeradius-server-2.1.10/src/main/ra dsniff.c:467: undefined reference to `pcap_fopen_offline' collect2: ld returned 1 exit status gmake[4]: *** [radsniff] Error 1 gmake[4]: Leaving directory `/root/freeradius-server-2.1.10/src/main' gmake[3]: *** [main] Error 2 gmake[3]: Leaving directory `/root/freeradius-server-2.1.10/src' gmake[2]: *** [all] Error 2 gmake[2]: Leaving directory `/root/freeradius-server-2.1.10/src' gmake[1]: *** [src] Error 2 gmake[1]: Leaving directory `/root/freeradius-server-2.1.10' make: *** [all] Error 2 [root@ott-freerad-101 freeradius-server-2.1.10]# I'm running an enterprise variant of Red Hat 4 64-bit with kernel 2.6.9-89.0.11.EL and gcc version: [root@ott-freerad-101 freeradius-server-2.1.10]# gcc -v Reading specs from /usr/lib/gcc/x86_64-redhat-linux/3.4.6/specs Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --disable-checking --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-java-awt=gtk --host=x86_64-redhat-linux Thread model: posix gcc version 3.4.6 20060404 (Red Hat 3.4.6-11) [root@ott-freerad-101 freeradius-server-2.1.10]# Note that this is on a fresh install of Linux and I did not have FreeRadius running on this machine before.

Edge case: TLS failure
by East, Bill 11 May '11

11 May '11

I feel I should put this out there just in case someone else does something as unusual as this: This morning, one of my staff members reported that her PC, which we're testing 802.1x authentication on, was dropping off the network. I thought to check the logfile and found Wed May 11 10:09:38 2011 : Error: TLS Alert write:fatal:bad record mac Wed May 11 10:09:38 2011 : Error: rlm_eap: SSL error error:1408F119:SSL routines:SSL3_GET_RECORD:decryption failed or bad record mac Wed May 11 10:09:38 2011 : Error: SSL: SSL_read failed in a system call (-1), TLS session fails. Googling came up with a lot of hits from this list, but none of the cases seemed to fit exactly. I restarted the daemon to see if there was a problem there but the error came back again. Finally since this seemed to be limited to the one machine alone I did some digging into the environment. Turns out, this is a newish machine, and the old one is still on the network and running. Further, she had just set a reservation for the new PC in DHCP, to use the old one's address. The old one, though, still had the old address. So we had two machines on a single switch port (using a dumb mini-switch), both with the same IP. We reassigned the old PC's IP and haven't seen a problem since.

Re: Freeradius-Users Digest, Vol 73, Issue 8
by Daniel Davidson 11 May '11

I finally got this figured out. It did not have anything do do with freeradius, but since others using the program might run into it, I figured I should post it here. The arp cache of the server was limited by default to 128 addresses, which was running out pretty quickly. So I inserted and applied the values below in sysctl.conf and everything works great now. net.ipv4.neigh.default.gc_thresh3 = 4096 net.ipv4.neigh.default.gc_thresh2 = 2048 net.ipv4.neigh.default.gc_thresh1 = 1024 Dan On 05/04/2011 01:51 AM, freeradius-users-request(a)lists.freeradius.org wrote: > Message: 3 > Date: Tue, 3 May 2011 20:56:12 +0100 > From: Alexander Clouter<alex(a)digriz.org.uk> > Subject: Re: ldap server connection timeout > To:freeradius-users@lists.freeradius.org > Message-ID:<s73698-k73.ln1(a)chipmunk.wormnet.eu> > > Daniel Davidson<danield(a)igb.uiuc.edu> wrote: >> > >> > My new wireless network tested great, but now that I have rolled it out >> > to the entire building, I get error messages like: >> > >> > Mon May 2 15:15:06 2011 : Error: rlm_ldap: ldap_search() failed: Timed >> > out while waiting for server to respond.

by Meyer Jerome 11 May '11

11 May '11

Hello, I've installed the latest freeradius version (freeradius-server-2.1.10) from source! SO, I configured it and tested it with the command [radiusd -X] and it is ok! Now, I would to start the daemon in a normal way (/etc/rc.d). I copy the rc.radiusd into /etc/rc.d but nothing is started. Try to start like : /usr/sbin/radiusd nothing is started... Have someone an Idea? Regards, Jérôme

Free Radius 2.1.8 + Mikrotik
by Ahmed Syed 10 May '11

10 May '11

Can someone give me a hint how to solve following: We are using PPPoE server with FreeRadius autentification and we are using Simultaneous Use Checking. We are limiting number of simultaneous connections to 1. The problem is in nonstandard situation when PPPoE server is nonstandardly restarted and there will stay open sessions on the radius. New connections are unauthorized because of simultaneous checking. We must manually delete open sessions. All users are Reject/authetication failed that time...

Re: Restrict user only to a NAS
by Marcos TP 10 May '11

10 May '11

I forgot to mention that I use MySQL to manage my users and NAS. In the table that records the users exists a field 'radnas_id' where I can tell the NAS that he is entitled to connect, but can not enable this restriction

Custom Accounting Fields
by Tim Donahue 10 May '11

10 May '11

Hi all, We are using Freeradius for accounting from our voip system. Is there documentation somewhere, that you can point me to, on how I can add a couple of custom vendor fields to the radacct database schema and the INSERT query? I have no problem reading the documentation, but I can't seem to find which documentation I need to review, especially to find what the default SQL query is, so I can make sure that the data stays consistent.
