3.ride.py crash

Gdk-ERROR **: The program 'python' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAlloc (insufficient resources for operation)'.
(Details: serial 2125 error_code 11 request_code 53 minor_code 0)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
aborting...

yum install libcanberra-gtk2.i686 -y

4. modify tftp configuration.

[atxuser@rlab021]~% cat /etc/xinetd.d/tftp 
# default: off
# description: The tftp server serves files using the trivial file transfer \
#       protocol.  The tftp protocol is often used to boot diskless \
#       workstations, download configuration files to network-aware printers, \
#       and to start the installation process for some operating systems.
service tftp
{
        socket_type             = dgram
        protocol                = udp
        wait                    = yes
        user                    = root
        server                  = /usr/sbin/in.tftpd
        server_args             = -s /tftpboot -c
        disable                 = no 
        per_source              = 11
        cps                     = 100 2
        flags                   = IPv6
}

5. restart tftp server

#service xinetd restart

6. issue: Error code 1: File not found

可能的原因:

1. 指定的文件不存在isc_dhcp.tar；

2. 或tftpd启动参数server_args中没有指定-c选项，允许上传文件

3. 或者有两个tftp进程，需要全部杀掉，然后service xinetd restart重启

# service ip6tables stop
# service iptables stop

# vi /etc/selinux/config  （SELINUX=disabled）

# /usr/sbin/setenforce 0

7. 配置eth2端口（netconf项目可忽略？）

1. 
#ifconfig eth2
inet6 addr: fe80::2e0:edff:fe1e:2c71/64

2.combine a new IPV6 address
2001:da8:201:0:2e0:edff:fe1e:2c71

3. modify ifcfg-eth2
#vi /etc/sysconfig/network-scripts/ifcfg-eth2
-----adding the following lines----------------
IPV6INIT=yes
IPV6_AUTOCONF=no
IPV6ADDR=2001:da8:201:0:2e0:edff:fe1e:2c71/64

4. restart ethx
#service network restart

8.dhcp issue: Can't bind to dhcp address: Address already in use

切换到root用户下
#ps -ef | grep dhcp
#kill -9 dhcp_pid

9. trigger LTB failed: File /vobs/esam/build/fulltests/COMMON/ONTMAPLIST.txt is missing

add ENV REPO for atxuser:

# su - atxuser
# cd /tftpboot/atx/atxuser
# cat  .profile
#!/bin/ksh
EDITOR=nedit
PRINTER=
WINEDITOR=nedit
DARK_BG=no
echo_dot=no
user=`whoami`
REPO=/repo/$user/atc
. $REPO/env/.profile.common

export REPO

10. Downgrade centos kernel

[root@rlab128 atxuser]# rpm -qa kernel
kernel-2.6.32-573.el6.x86_64
[root@rlab128 atxuser]# 
[root@rlab128 atxuser]# rpm -ivh kernel-2.6.32-504.el6.x86_64.rpm --force
warning: kernel-2.6.32-504.el6.x86_64.rpm: Header V4 DSA/SHA1 Signature, key ID 192a7d7d: NOKEY
Preparing...                ########################################### [100%]
   1:kernel                 ########################################### [100%]

[root@rlab128 atxuser]# reboot

# reboot

reboot
