Hi guys, I have my driverdisk created and the files are on a USB pendrive. How do I make the USB pendrive /dev/sdb and not /dev/sda??? I am wanting the installation to take place on sda and the driver disk to be sdb? My driver disk is a network driver disk, r8168. Jerry

ipsec net-to-net problem
by brad＠bradandkim.net 16 Feb '09

16 Feb '09

I am trying to set up an ipsec net-to-net VPN and am having problems. Here is a diagram of the setup: LAN A --> Host A ----> Internet <---- Host B <-- LAN B LAN A = 10.10.2.0/24 LAN A gateway = 10.10.2.254 Host A internal = 10.10.2.254 Host A external = xx.xx.xx.xx Host B external (see below) Host B internal = 10.10.1.10 LAN B = 10.10.1.0/24 LAN B gateway = 10.10.1.252 (F5 Big IP) Host A is CentOS5 and is a router/firewall for LAN A. Host B is RHEL4 and does not have a public IP. It is behind an F5 BigIP and the BigIP forwards all traffic for yy.yy.yy.yy to Host B. Likewise it masks Host B's outbound traffic as yy.yy.yy.yy. I can get this tunnel to come up but seem to be having problems on the Host A side. If I run 'tcpdump |grep -i esp' on Host A and ping a host on LAN A from a host on LAN B (whose routing table was adjusted to go through Host B for the 10.10.2.0 network), I see ESP traffic on Host A: AH(spi=0x04c98137,seq=0x3): IP 10.10.1.10 > xx.xx.xx.xx: ESP(spi=0x07b6bcd3,seq=0x3), length 116 (ipip-proto-4) If I ping a host on LAN B from a host on LAN A I don't see any ESP traffic on either Host A or Host B and the host doing the ping gets a 'Destination Host Unreachable'. It seems like a problem with the routing on Host A. Here is the result of setkey -D on both hosts: Host A: xx.xx.xx.xx yy.yy.yy.yy esp mode=tunnel spi=169285624(0x0a1717f8) reqid=0(0x00000000) E: 3des-cbc ce370c79 68e74da7 79ba58b9 1605f149 f3e98e5b 9984da9b A: hmac-sha1 ea9dba47 cf6a4c04 7e949d4f a8f304f0 76e006c7 seq=0x00000000 replay=4 flags=0x00000000 state=mature created: Feb 16 12:46:01 2009 current: Feb 16 12:47:13 2009 diff: 72(s) hard: 3600(s) soft: 2880(s) last: hard: 0(s) soft: 0(s) current: 0(bytes) hard: 0(bytes) soft: 0(bytes) allocated: 0 hard: 0 soft: 0 sadb_seq=3 pid=5198 refcnt=0 xx.xx.xx.xx yy.yy.yy.yy ah mode=tunnel spi=173186772(0x0a529ed4) reqid=0(0x00000000) A: hmac-sha1 82aaec77 11dfb67c 7fbb7f7c 152c2764 4445ad8e seq=0x00000000 replay=4 flags=0x00000000 state=mature created: Feb 16 12:46:01 2009 current: Feb 16 12:47:13 2009 diff: 72(s) hard: 3600(s) soft: 2880(s) last: hard: 0(s) soft: 0(s) current: 0(bytes) hard: 0(bytes) soft: 0(bytes) allocated: 0 hard: 0 soft: 0 sadb_seq=2 pid=5198 refcnt=0 yy.yy.yy.yy xx.xx.xx.xx esp mode=tunnel spi=166536016(0x09ed2350) reqid=0(0x00000000) E: 3des-cbc b63a5538 c6a2dd3b f449df6e c594cd16 644a59d4 cb45dfef A: hmac-sha1 5d8d015c f8e8e12f d117dc5b fc64d2ed f3ca79b5 seq=0x00000000 replay=4 flags=0x00000000 state=mature created: Feb 16 12:46:01 2009 current: Feb 16 12:47:13 2009 diff: 72(s) hard: 3600(s) soft: 2880(s) last: hard: 0(s) soft: 0(s) current: 0(bytes) hard: 0(bytes) soft: 0(bytes) allocated: 0 hard: 0 soft: 0 sadb_seq=1 pid=5198 refcnt=0 yy.yy.yy.yy xx.xx.xx.xx ah mode=tunnel spi=84103999(0x0503533f) reqid=0(0x00000000) A: hmac-sha1 022dbd45 248b1ffa 05d94068 22e3c530 5485a468 seq=0x00000000 replay=4 flags=0x00000000 state=mature created: Feb 16 12:46:01 2009 current: Feb 16 12:47:13 2009 diff: 72(s) hard: 3600(s) soft: 2880(s) last: hard: 0(s) soft: 0(s) current: 0(bytes) hard: 0(bytes) soft: 0(bytes) allocated: 0 hard: 0 soft: 0 sadb_seq=0 pid=5198 refcnt=0 Host B: xx.xx.xx.xx 10.10.1.10 esp mode=tunnel spi=169285624(0x0a1717f8) reqid=0(0x00000000) E: 3des-cbc ce370c79 68e74da7 79ba58b9 1605f149 f3e98e5b 9984da9b A: hmac-sha1 ea9dba47 cf6a4c04 7e949d4f a8f304f0 76e006c7 seq=0x00000000 replay=4 flags=0x00000000 state=mature created: Feb 16 12:45:57 2009 current: Feb 16 12:47:35 2009 diff: 98(s) hard: 3600(s) soft: 2880(s) last: hard: 0(s) soft: 0(s) current: 0(bytes) hard: 0(bytes) soft: 0(bytes) allocated: 0 hard: 0 soft: 0 sadb_seq=3 pid=15049 refcnt=0 xx.xx.xx.xx 10.10.1.10 ah mode=tunnel spi=173186772(0x0a529ed4) reqid=0(0x00000000) A: hmac-sha1 82aaec77 11dfb67c 7fbb7f7c 152c2764 4445ad8e seq=0x00000000 replay=4 flags=0x00000000 state=mature created: Feb 16 12:45:57 2009 current: Feb 16 12:47:35 2009 diff: 98(s) hard: 3600(s) soft: 2880(s) last: hard: 0(s) soft: 0(s) current: 0(bytes) hard: 0(bytes) soft: 0(bytes) allocated: 0 hard: 0 soft: 0 sadb_seq=2 pid=15049 refcnt=0 10.10.1.10 xx.xx.xx.xx esp mode=tunnel spi=166536016(0x09ed2350) reqid=0(0x00000000) E: 3des-cbc b63a5538 c6a2dd3b f449df6e c594cd16 644a59d4 cb45dfef A: hmac-sha1 5d8d015c f8e8e12f d117dc5b fc64d2ed f3ca79b5 seq=0x00000000 replay=4 flags=0x00000000 state=mature created: Feb 16 12:45:57 2009 current: Feb 16 12:47:35 2009 diff: 98(s) hard: 3600(s) soft: 2880(s) last: hard: 0(s) soft: 0(s) current: 0(bytes) hard: 0(bytes) soft: 0(bytes) allocated: 0 hard: 0 soft: 0 sadb_seq=1 pid=15049 refcnt=0 10.10.1.10 xx.xx.xx.xx ah mode=tunnel spi=84103999(0x0503533f) reqid=0(0x00000000) A: hmac-sha1 022dbd45 248b1ffa 05d94068 22e3c530 5485a468 seq=0x00000000 replay=4 flags=0x00000000 state=mature created: Feb 16 12:45:57 2009 current: Feb 16 12:47:35 2009 diff: 98(s) hard: 3600(s) soft: 2880(s) last: hard: 0(s) soft: 0(s) current: 0(bytes) hard: 0(bytes) soft: 0(bytes) allocated: 0 hard: 0 soft: 0 sadb_seq=0 pid=15049 refcnt=0 Here are the ifcfg-ipsec files for each host.

INIT: Id "snmp" respawning too fast: disabled for 5 minutes
by David Halik 16 Feb '09

16 Feb '09

Hello all, I recently started seeing these messages on the consoles of three production Centos 5.2 servers. They have been occurring nonstop for the past few days and show up routinely every five minutes. INIT: Id "snmp" respawning too fast: disabled for 5 minutes INIT: Id "snmp" respawning too fast: disabled for 5 minutes INIT: Id "snmp" respawning too fast: disabled for 5 minutes Despite trying to debug this and googling for the last couple of hours, I haven't had any luck as to why the errors are generated or how to fix them. There are a ton of posts on the web related to other Id's, such as various tty ports and "x", but I haven't seen a single thing related to "snmp". The answer usually seems to be that there are misconfigured lines in /etc/inittab, but in my case there is nothing even remotely related to "Id snmp" in inittab. The make matters more confusing, snmp isn't installed or being used on these machines. I doubled checked and the extent of any snmp packages are these two: # rpm -qa | grep -i snmp perl-Net-SNMP-5.2.0-1.2.el5.rf net-snmp-libs-5.3.1-24.el5_2.1 Both only contain a couple of libraries, so I hardly believe they have anything to do with it. According to what I've learned, this error is usually generated when init tries to continually respawn a process that dies immediately... but as to what process it could possible be I have no idea. I even tried to strace init (-p1), but apparently this is a forbidden operation: # strace -p1 attach: ptrace(PTRACE_ATTACH, ...): Operation not permitted That's a shame too, but at least I could see what init is trying to do. Any ideas? I'm just about stumped as to how to proceed at this point. Thanks in advance. -- ================================ David Halik System Administrator OIT-CSS Rutgers University dhalik(a)jla.rutgers.edu ================================

logs such as messages, boot.log, and kernel contained 0 size
by Frank Ling 16 Feb '09

16 Feb '09

Hi, My both CentOS 5 servers have logging problems. Logs such as messages, boot.log, kernel, spooler, and tallylog in /var/log directory are all 0 size. The kernel is: Linux 2.6.18-92.1.22.el5 #1 SMP. Since the /var/log/messages contained no information it would be impossible to troubleshoot the problem. I am very sure both systems have not been hacked by others.

I mean that when I installed CentOS 5.2 on a box with ASUS P6T, the installator of CentOS can not found 2 on-board NIC. So I have to add another NIC to work. -- http://vnoss.org

ASUS PT6 or Intel DX58SO for CentOS?

I'm looking at setting up a new machine to run CentOS 5 and a few VMWare machines to test Windows XP, Vista, and 7. I'm working with a custom PC shop and they've recommended I use either the ASUS PT6 or Intel DX58SO. Any feedback good or bad on either of these? Thanks! --Chris

funny SMS server tips
by Fajar Priyanto 16 Feb '09

16 Feb '09

Hi guys, Hehe.. I thought I want to share this. In previous email, I said about monitoring server room. I just realize that we have this quite old sms server appliance in the room. It's still running though. I want to setup cronjob from linux machines, to send mail to that sms server, and it will then send sms to my cell about the machine condition. Problem is, nobody knows how to configure the sms server, and there's no docs beside a little description in the web UI. Been googling around few hours, but since it's quite old and proprietary, no good result. Problem is, the sms server's qmail refuses to work if I use hostname in the mail like mycellnum@sms-server. If I want to use mycellnum(a)192.168.1.100, sendmail refuses to send it as "host not found". So, out of curiosity, I define this in this /etc/hosts: 192.168.1.100 192.168.1.100 And now sending from sendmail to mycellnum(a)192.168.1.100 works! is it a feature or what? In network convention, all-numeric hostname is not allowed right? Hehe.. anyway, now I can monitor my server room using sms.
