Re: [rhelv6-list] network problem on RHEL6.3



I do some tests and I have problems with 192.168.114 private network . Infact if I connect from public network (193.204.165.*) or another private network (192.168.115.) it's all ok, but for example, if I connect from a host with IP address 192.168.114.30 in 'ssh -vvv www 193 204 165 224' the output is "ssh: connect to 193.204.165.224 port 22: no route to host". When I connect with 'ssh -vvv www 192 168 114 60' I see "www 192 168 114 60's password:" I have this network problem for all services on server (http, https, mail) and not for only ssh. This server worked with RHEL5.8 but after upgrade to RHEL6.3 there is this problem.

Any idea?

Hi, I have a problem with two network card on RHEL6.3
I configure the network with  NetworkManager  and in
/etc/sysconfig/network-scripts/ifcfg-eth1(2) I change NM_CONTROLLED='no'
so I run service NetworkManager stop, chkconfig NetworkManager off and
service network restart.
In this way only second card works. If I disable the second card, the
first works.
How can I do?

This is my configuration file:
/etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE="eth1"
ONBOOT=yes
HWADDR=00:1D:0F:C3:42:F2
TYPE=Ethernet
BOOTPROTO=none
IPADDR=193.204.165.224
NETMASK=255.255.255.0
GATEWAY=193.204.165.1
DNS1=193.204.165.131
DNS2=193.205.139.10
IPV6INIT=no

/etc/sysconfig/network-scripts/ifcfg-eth2
DEVICE="eth2"
HWADDR=00:24:01:32:06:C7
TYPE=Ethernet
BOOTPROTO=none
IPADDR=192.168.114.60
NETMASK=255.255.255.0
#GATEWAY=192.168.114.1
DNS1=193.204.165.131
DNS2=193.205.139.10
IPV6INIT=no
ONBOOT=yes

/etc/sysconfig/network
NETWORKING=yes
HOSTNAME=web.mat.uniroma3.it

/etc/resolv.conf
search mat.uniroma3.it
nameserver 193.204.165.131
nameserver 193.205.139.10



Thanks in advance

Hi Tiziiana,

	Can you send the content of your
