Re: FreeBSD 4.9 - NIS Authentication Problem (SSHD Illegal User ERROR)

The ypcat commands are working and I can see the passwd and group files, however when I attempt to login to the machine I keep getting SSHD Illegal User Errors. As a first guess I would recommend: - check /etc/hosts.allow (ssh access control used by FreeBSD) - shadow support - rpcinfo -p works OK? - run ypserv daemon in foregound, check its output -- Volker Jahns, [EMAIL PROTECTED] ___ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[EMAIL PROTECTED]"
rpcinfo Problem
Running rpcbind on a FreeBSD 6.1 testsystem has horrible effects, when - rpcbind is started at system boottime by the rc.conf directive rpcbind_enable="YES" - rpcinfo -p localhost is run ( this command then hangs until the system has died) The top output shows high load and 'many' rpcbind processes which have been started. -- last pid: 48637; load averages: 3.99, 3.24, 3.23 up 0+07:47:18 16:02:42 1832 processes:3 running, 195 sleeping, 1633 waiting, 1 lock CPU states: 5.2% user, 0.0% nice, 26.8% system, 4.3% interrupt, 63.7% idle Mem: 121M Active, 20M Inact, 88M Wired, 4688K Cache, 34M Buf, 1004K Free Swap: 470M Total, 244M Used, 226M Free, 51% Inuse, 22M In, 26M Out PID USERNAME THR PRI NICE SIZERES STATETIME WCPU COMMAND 317 root1 1280 1440K 424K RUN 44:17 7.37% rpcbind 37057 root1 960 6524K 3468K RUN 0:20 0.06% top 296 root1 960 1300K 0K WAIT 1:06 0.00% 437 root1 960 3408K 0K WAIT 0:00 0.00% 538 root1 960 6092K 0K WAIT 0:00 0.00% 447 root1 80 1312K 0K WAIT 0:00 0.00% 441 smmsp 1 200 3300K 0K pause0:00 0.00% 383 root1 960 1212K 0K WAIT 0:00 0.00% 541 root1 200 3996K 0K pause0:00 0.00% 99806 root1 40 1468K 0K WAIT 0:00 0.00% 38770 root1 40 1464K 0K WAIT 0:00 0.00% 20459 root1 40 1468K 0K WAIT 0:00 0.00% 21924 root1 40 1440K 0K WAIT 0:00 0.00% 426 root1 960 3356K 0K select 0:00 0.00% 49102 root1 40 1468K 0K WAIT 0:00 0.00% 10715 root1 40 1468K 648K kqread 0:00 0.00% rpcbind 49102 root1 40 1468K 0K WAIT 0:00 0.00% 45921 root1 40 1464K 0K WAIT 0:00 0.00% 45947 root1 40 1464K 0K WAIT 0:00 0.00% -- The output of some well-known commands w/ the system in this state is puzzling me: -- orion# dmesg No more processes. -- -- ssh orion -l root ssh_exchange_identification: Connection closed by remote host -- Moreover, system log worries me: -- Mar 8 08:20:26 orion kernel: kern.maxfiles limit exceeded by uid 0, please see tuning(7).

Re: rpcinfo Problem
The following configuration statements reproducibly crash FreeBSD 6.1 and 6.2 when calling "rpcinfo -p" or "rpcinfo -p localhost" ( see more details in the first posting) -- rpcbind_enable="YES" rpcbind_flags="-i -l" nisdomainname="tdom" nis_client_enable="YES" -- I would be tempted to identify this behaviour as a (serious) bug. Workaround If the nis_client_flags option is uncommented like #nis_client_flags="-S tdom,tdomserv.tdom.de,tdomserv -m" -- Volker Jahns, [EMAIL PROTECTED] > Running rpcbind on a FreeBSD 6.1 testsystem has horrible effects, when > > - rpcbind is started at system boottime by the rc.conf directive > rpcbind_enable="YES" > - rpcinfo -p localhost is run ( this command then hangs until the system > has died) > > > The top output shows high load and 'many' rpcbind processes which have > been started. > -- > last pid: 48637; load averages: 3.99, 3.24, 3.23 up 0+07:47:18 > 16:02:42 > 1832 processes:3 running, 195 sleeping, 1633 waiting, 1 lock > CPU states: 5.2% user, 0.0% nice, 26.8% system, 4.3% interrupt, 63.7% > idle > Mem: 121M Active, 20M Inact, 88M Wired, 4688K Cache, 34M Buf, 1004K Free > Swap: 470M Total, 244M Used, 226M Free, 51% Inuse, 22M In, 26M Out > > PID USERNAME THR PRI NICE SIZERES STATETIME WCPU COMMAND > 317 root1 1280 1440K 424K RUN 44:17 7.37% rpcbind > 37057 root1 960 6524K 3468K RUN 0:20 0.06% top > 296 root1 960 1300K 0K WAIT 1:06 0.00% > 437 root1 960 3408K 0K WAIT 0:00 0.00% > 538 root1 960 6092K 0K WAIT 0:00 0.00% > 447 root1 80 1312K 0K WAIT 0:00 0.00% > 441 smmsp 1 200 3300K 0K pause0:00 0.00% > 383 root1 960 1212K 0K WAIT 0:00 0.00% > 541 root1 200 3996K 0K pause0:00 0.00% > 99806 root1 40 1468K 0K WAIT 0:00 0.00% > 38770 root1 40 1464K 0K WAIT 0:00 0.00% > 20459 root1 40 1468K 0K WAIT 0:00 0.00% > 21924 root1 40 1440K 0K WAIT 0:00 0.00% > 426 root1 960 3356K 0K select 0:00 0.00% > 49102 root1 40 1468K 0K WAIT 0:00 0.00% > 10715 root1 40 1468K 648K kqread 0:00 0.00% rpcbind > 49102 root1 40 1468K 0K WAIT 0:00 0.00% > 45921 root1 40 1464K 0K WAIT 0:00 0.00% > 45947 root1 40 1464K 0K WAIT 0:00 0.00% > -- > > The output of some well-known commands w/ the system in this state is > puzzling me: > -- > orion# dmesg > No more processes. > -- > -- > ssh orion -l root > ssh_exchange_identification: Connection closed by remote host > -- > > Moreover, system log worries me: > -- > Mar 8 08:20:26 orion kernel: kern.maxfiles limit exceeded by uid 0, > please see > tuning(7). > Mar 8 08:20:26 orion kernel: kern.maxfiles limit exceeded by uid 0, > please see > tuning(7). > Mar 8 08:20:26 orion syslogd: /dev/console: Too many open files in > system: Too > many open files in system > Mar 8 07:20:25 orion rpcbind: warning: /etc/hosts.allow, line 23: cannot > open / > etc/hosts.allow: Too many open files in system > -- > > Running rpcinfo -p from a remote system can be used to > benchmark this FreeBSD system. sockstat shows the TCP connects to rpcbind > from the remote system and everything is fine. > > > If rpcbind is _not_ started at boottime, but from the commandline once the > system is up, rpcinfo -p localhost works as expected. > > I want to run NIS on the system, so rpcbind must run in reliable manner. > > Any help is much appreciated. > -- > Volker Jahns, [EMAIL PROTECTED] > ___ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[EMAIL PROTECTED]"
