Re: [CentOS] Critical update for bash released today.
John Doe wrote: If I understood correctly, the current fix is incomplete and another fix is planned? Yes. More info here - https://access.redhat.com/security/cve/CVE-2014-7169 Also, in the advisory, RH says that after the update, servers need to be rebooted... Really? No. From https://access.redhat.com/articles/1200223 --- Do I need to reboot or restart services after installing this update? No, a reboot of your system or any of your services is not required. This vulnerability is in the initial import of the process environment from the kernel. This only happens when Bash is started. After the update that fixes this issue is installed, such new processes will use the new code, and will not be vulnerable. Conversely, old processes will not be started again, so the vulnerability does not materialize. --- -- Paul Norton ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

In the morning (after noticing it died) I try to run `service postfix stop` and I get a failed start. Running `ps ax | grep postfix` I can see one process still running for postfix. After killing this, I am able to run `service postfix start`. I see a lot of this in my maillog: Nov 7 00:25:13 servername postfix/smtpd[16727]: lost connection after CONNECT from unknown[201.251.x.x] Nov 7 00:25:13 servername postfix/smtpd[16715]: disconnect from unknown[201.251.x.x] Nov 7 00:25:13 servername postfix/smtpd[16727]: disconnect from unknown[201.251.x.x] Nov 7 00:25:13 servername postfix/smtpd[16723]: warning: connect to private/anvil: Resource temporarily unavailable Nov 7 00:25:13 servername postfix/smtpd[16723]: warning: problem talking to server private/anvil: Resource temporarily unavailable Nov 7 00:25:13 servername postfix/smtpd[16723]: lost connection after CONNECT from unknown[201.251.x.x] Nov 7 00:25:13 servername postfix/smtpd[16723]: disconnect from unknown[201.251.x.x] Nov 7 00:27:22 servername postfix/smtpd[16184]: warning: timeout on private/anvil while reading input attribute name Nov 7 00:27:22 servername postfix/smtpd[16184]: warning: problem talking to server private/anvil: Connection timed out Nov 7 00:27:22 servername postfix/smtpd[16910]: warning: timeout on private/anvil while reading input attribute name Nov 7 00:27:22 servername postfix/smtpd[16910]: warning: problem talking to server private/anvil: Connection timed out Nov 7 00:27:22 servername postfix/smtpd[16726]: warning: timeout on private/anvil while reading input attribute name Nov 7 00:27:22 servername postfix/smtpd[16726]: warning: problem talking to server private/anvil: Connection timed out Nov 7 00:27:23 servername postfix/smtpd[16184]: warning: connect to private/anvil: Resource temporarily unavailable Nov 7 00:27:23 servername postfix/smtpd[16184]: warning: problem talking to server private/anvil: Resource temporarily unavailable Nov 7 00:27:23 servername postfix/smtpd[16184]: lost connection after CONNECT from unknown[201.251.x.x] Nov 7 00:27:23 servername postfix/smtpd[16184]: disconnect from unknown[201.251.x.x] Nov 7 00:27:23 servername postfix/smtpd[16910]: warning: connect to private/anvil: Resource temporarily unavailable Nov 7 00:27:23 servername postfix/smtpd[16910]: warning: problem talking to server private/anvil: Resource temporarily unavailable Nov 7 00:27:23 servername postfix/smtpd[16910]: lost connection after CONNECT from unknown[86.123.x.x] Nov 7 00:27:23 servername postfix/smtpd[16910]: disconnect from unknown[86.123.x.x] Nov 7 00:27:23 servername postfix/smtpd[16726]: warning: connect to private/anvil: Resource temporarily unavailable Nov 7 00:27:23 servername postfix/smtpd[16726]: warning: problem talking to server private/anvil: Resource temporarily unavailable Nov 7 00:27:23 servername postfix/smtpd[16726]: lost connection after CONNECT from cpe-024-x-x-x.carolina.x.x.com[24.74.x.x] Nov 7 00:27:23 servername postfix/smtpd[16726]: disconnect from cpe-024-074-x-x.carolina.x.x.com[24.74.x.x] TIA for any suggestions. -- Paul Norton Systems Administrator Neoverve - www.neoverve.com Neoverve Blog - http://blog.neoverve.com/ ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] Network issue after new kernel install
Hello CentOS list, On all of my CentOS 5 VMWare ESX3 virtual machines (about 15), after installing a new kernel and rebooting the machine, the Network script tries to run dhclient and can't determine the IP info (since I don't run a dhcpd server... it's a static IP only lan). This also backs up my ifcfg-eth0 file to ifcfg-eth0.bak and writes a new ifcfg-eth0 that has dhcpd with no IP info. Copying the ifcfg-eth0.bak to ifcfg-eth0 and running /etc/init.d/network start or ifup eth0 brings my network back up. This is an example of what one of my ifcfg-eth0 files looks like... # Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE] DEVICE=eth0 BROADCAST=69.x.x.x #HWADDR=00:50:56:9C:19:7D IPADDR=69.x.x.x IPV6ADDR= IPV6PREFIX= NETMASK=255.255.255.0 NETWORK=69.x.x.0 ONBOOT=yes Any ideas?

I have found that kudzu does this if it detects changes in the MAC addresses of your NICs. Did you clone/copy your virtual machine and did VMware regenerate MAC addresses for your virtual NICs? Yes, these are all clones(From one base image). Would I just copy the MAC address given from VMWARE to the ifcfg-eth0 file? -- Paul Norton Systems Administrator Neoverve - www.neoverve.com Neoverve Blog - http://blog.neoverve.com/ ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
