Local Host Routing
by Al Sparks 02 Jun '09

02 Jun '09

I have, a machine running RHEL ES 4.7 with 2 physical interfaces. eth0 Link encap:Ethernet HWaddr 00:14:22:1C:B4:EA inet addr:10.7.13.61 Bcast:10.7.13.255 Mask:255.255.255.0 inet6 addr: fe80::214:22ff:fe1c:b4ea/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:590936429 errors:0 dropped:0 overruns:0 frame:0 TX packets:590246457 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:361946964 (345.1 MiB) TX bytes:3358327885 (3.1 GiB) eth1 Link encap:Ethernet HWaddr 00:14:22:1C:B4:EB inet addr:10.254.214.16 Bcast:10.254.214.255 Mask:255.255.255.0 inet6 addr: fe80::214:22ff:fe1c:b4eb/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:423509 errors:0 dropped:0 overruns:0 frame:0 TX packets:19440 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:35948215 (34.2 MiB) TX bytes:2850651 (2.7 MiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:115612666 errors:0 dropped:0 overruns:0 frame:0 TX packets:115612666 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:96931918 (92.4 MiB) TX bytes:96931918 (92.4 MiB) By default both interfaces route through the default gateway. $ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 10.7.13.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 10.254.214.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 0.0.0.0 10.7.13.1 0.0.0.0 UG 0 0 0 eth0 The LAN, 10.254.214.0/24 that eth1 is a part of, is configured to not route at all. (Actually it's a VLAN, if that's germane). However, when I remove the route entry with: # route del -net 10.254.214.0 netmask 255.255.255.0 I lose connectivity with the nodes on the LAN. When I do an $ nmap -sP 10.254.214.0/24 the only thing that shows up is Host 10.254.214.16 appears to be up which is the IP address of eth1. I shouldn't need a routing gateway to reach these devices. In addition, even when the routing entry is there (or not) a ping from eth1 $ ping -I eth1 10.7.13.1 gives me destination unreachable, so the entry is pointless. BTW, $ ping -I eth0 10.7.13.1 works fine as it should. I guess it's not a big deal. If it works don't fix it. But I'm still curious. Any ideas? === Al

Oct 20 02:01:01 linux kernel: type=1106 audit(1224435661.064:65210): user pid=25860 uid=0 auid=0 msg='PAM: session close acct="root" : exe="/usr/sbin/crond" (hostname=?, addr=?, terminal=cron res=success)' Is there any way to disable this messages? if I should change /etc/audit/auditd.conf file, please let me know which config should I change.

release/update question
by Matthias Leopold 02 Jun '09

02 Jun '09

hi, since i don't use centos very heavily i'm not too familiar with the centos/rhel release/update process (and i didn't do much research on this): is it normal behavior that through the use of "yum update" systems are forced to follow the point releases of a major release (5.0 -> 5.1 -> 5.2, etc)? is there a way and would it make sense to stay within one particular release and receive only security updates? or is this question pointless because point releases _are_ only security updates? thx for teaching a debian user matthias

Then i want to integrate with NetworkManager and vpnc so i also installed NetworkManager-vpnc 7.0. I configured vpn connection and tried to connect. It looks like it connected but when i try to login my server at behind of the vpn server, i cant reach them. I check the routes and it looks like at below. [root@localhost sysconfig]# route Destination Gateway Genmask Flags Metric Ref Use Iface xxx.xxx.xxx.xxx 10.15.1.1 255.255.255.255 UGH 0 0 0 eth0 10.255.0.136 * 255.255.255.248 U 0 0 0 tun0 10.15.0.0 * 255.255.0.0 U 1 0 0 eth0 default * 0.0.0.0 U 0 0 0 tun0 When i check the log files everthing seems ok at all.

I can reach my servers. There isnt any error while try with networkmanager vpnc, but it cant connect actually When i looked at routes again. It is shown the same values. Any idea? -- Abdullah Teke --------------------------- abdullahteke(a)gmail.com www.abdullahteke.com

Changing a user's shell on CentOS Directory Server?
by Matt Harrington 02 Jun '09

02 Jun '09

Should unprivileged users be able to change their shell with lchsh on 5.3 and, if it matters, CentOS Directory Server? lchsh seems to require more open permissions than those which come with a default installation: Error initializing libuser: could not open configuration file `/etc/default/useradd': Permission denied.
