snmpwalk Mixed Fail
by Peter Brady 27 Mar '15

27 Mar '15

Hi All, I have a C6 (latest patches) physical machine that I use for network and server monitoring, predominantly over SNMP. It is on VLAN80. My network management interfaces on the switches are on VLAN50 with routing between the VLANs. I recently changed the router to a CISCO ASA 5505 (reasonably recent IOS version, certainly post HeartBleed), with the management interface on a higher security level and added appropriate ACLs and firewall rules to access VLAN50. I promptly lost SNMP contact with roughly half the switches on VLAN50. ICMP, http/s, ssh etc are still working across the router. Its just SNMP and only to a subset of devices that is the problem. FWITW the switches I've lost contact with are Netgear Layer 2 and 3 managed switches, not that brand should make a difference. Some other Netgear WAPs are fine and all CISCO devices are fine. With a machine on the same VLAN all is happy. I've tried the obvious on the C6 box: iptables, routing tables, SELinux. No luck. Tried snmpwalk with DNS and IP address, no luck. The generic response is: snmpwalk -v1 -c YYYY XXX.XXX.XXX.XXX Timeout: No Response from XXX.XXX.XXX.XXX with an exit code of 1. I've got a MacOSX box running Yosemite on the same VLAN80 with the same rules in the ASA, which works perfectly. They both share the same ASA rule set, which leads me to suspect that the ASA is not at fault - but can't be 100% certain. Also on the ASA logs I can see the incoming connections being accepted and opened through. I'm not running any SNMP packet inspection on the ASA. I noticed that the snmp versions between C6 (5.5) and OSX 10.10 (5.7) were different, so have tried a C7 VM (5.7). Still no luck. A second OSX box on a third VLAN, with a different ASA ruleset also works. A third physical C6 box on a fourth VLAN also shows the same symptoms: can ping, ssh etc but no SNMP. Given the above symptoms, I'm leaning to a CentOS/RHEL problem because the OSX boxes work fine. I can't definitively rule out the ASA being the cause of this though. This one's got me stumped so any suggestions would be gratefully accepted. Thanks in advance, -pete -- Peter Brady Email: pdbrady(a)ans.com.au Skype: pbrady77

C6 New Kernel 2.6.32-504.12.2 PPTP fail
by Ken Smith 26 Mar '15

26 Mar '15

Hi All, Anyone else seeing this. Just updated to kernel 2.6.32-504.12.2.el6.x86_64 and pptp vpn (invoked via Gnome Network Manager) fails to connect. Boot up the previous 2.6.32-504.8.1.el6.x86_64 and pptp all good. OpenVPN is not affected. Anyone else seeing this. I have log file details if anyone wants those. Don't see it reported elsewhere. Thanks Ken -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

Proper check of openssl usage in processes?
by Rafał Radecki 26 Mar '15

26 Mar '15

Hi All :) I need to check and possibly update openssl on my fleet of servers. I would like to avoid reboot if possible. I think that I can: - update openssl version with yum - check all daemon processes which are constantly running in the os, for example for sshd something like ldd `which sshd` | awk '/\// { print $3 }' | grep crypto | xargs strings | grep -i openssl to verify if the old openssl version is still used - if it is still used (I think that without a process restart the old version will be used) I will perform restart of the process Can this kind of check be done in some other way? BR, Rafal.

Upgraded Firefox due to today's security announcement. Closed Firefox and restarted but after about 20 seconds, Firefox stopped trying to start. No error messages displayed. Firefox would not start in safe mode. Reluctant to try Firefox with complete reset as might loose passwords and other settings made in about:config Have downgraded Firefox > Removed: > firefox.i386 0:31.5.3-1.el5.centos firefox.x86_64 0:31.5.3-1.el5.centos > > Installed: > firefox.i386 0:31.5.0-1.el5.centos firefox.x86_64 0:31.5.0-1.el5.centos Have looked in /var/logs but can not see anything relevant. How can I identify the cause of the problem ? Thanks, Paul. England, EU. Je suis Charlie.

If you're using a drive 2TB or smaller, and an MBR, rather than a GPT, you can *only* have four primary partitions. To make more, one of those must be an extended partition, and you can create additional partitions in that. One question: why do you need so many? mark

xfs_quota problem
by m.roth＠5-cent.us 25 Mar '15

25 Mar '15

I brought this up a month or so ago, and am just back to it: I've got a large RAID filesystem, mounted in one location, /<mntpt>/x/workspace, but we're having project directories that are under that magically appear under /workspace, as /workspace/projname1.... I need to set up xfs quotas by project, and I can't seem to find the right syntax. CentOS 6. Note that it's *project* quotas, which according to the docs and man pages do not need to be a filesystem. Too much googling, with high a noise to signal ratio. mark
