Re: [CentOS] What about port 2048 for GRE(47) packaged in ip protocol
encryption/decryption I mean. The kernel can't decrypt the packet eventually, kernel sends out the icmp. Just remember this part last time I track it down to the kernel side. You may have to take a look at your application why the gre doesn't setup correctly.

Sorry for my bad english. Hope could > help me this time First, who is this they who recommend a "fresh" install of CentOS, and what's the software? There's absolutely no reason I know of, nor am I aware of any software, that requires you to do a complete new install of the O/S (other than, maybe, for WinDoze...). In short, I think a) they're full of it; b) they have no idea what they're talking about, and don't know *Nix, or c) just what is it that's *in* that software?

Hi All, I have a Drobo, connected to a CentOS 6.4 box. The box sees it as /dev/sdg. I want to format it ext3 (as they dont support ext4) but when I try I get: # fdisk -u /dev/sdg WARNING: GPT (GUID Partition Table) detected on '/dev/sdg'! The util fdisk doesn't support GPT.

Re: [CentOS] web collaboration packages.
Hi John, I can get through the install but Zimbra wont start. It says it started, but didn't I get LDAP errors, Sasl errors, AV and antispam. I worked though them a lot yesterday but I still can not get the mta started and nothing starts listening on 443 either. I have Apache not listening to 443, only 80. I turned off the firewall, postfix, sendmail, all just to be sure. Both stopping the service and chkconfig so it wont start up again on startup. I was really close yesterday but I gave up again. I even tried 7.2.3 instead of 8.0.3 and that seemed worse. I uninstalled everything and removed all the pieces and figured that I would give it a shot again today.

[CentOS] How to determine 64 vs 32 bit processor
I have been tied up with other work and Holidays. Now back to some server work that is long overdue. I lost an old server yesterday so it is crunch time. I believe my new platform is suppose to be an x86_64. The order form says 64 bit. I booted Centos 6.3 i386 liveCD to check the system out before an install. uname -i reports i386 dmidecode -t processor reports Characteristics of 64 bit capable. The processor is an AMD duo-core Opteron. I thought that in a prior thread I found that booting with an i386 live CD and using uname would confirm the processor type. It seems not. I am going to go with the various evidence and start a x86_64 install, but what is with uname? thanks ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Last night, I didn't get to touch it - got one state and one commonwealth worth of taxes to finish, and then there was the document that I had to get to my (contracting co) manager, whose formatting was screwed up in libreoffice, and I *had* to use my work laptop and M$ Office, and Word I thought 07, was it? was Not Good; this is absolute and UTTER CRAP. For example, I want some bullet points, and if a sentence is longer than one line, I want the second and any other lines indented from the start of the bullet. Couldn't do it. Wouldn't let me. And trying to copy from an editable field, and it only giving me the whole section, not just what I was highlighting And on, and on In conclusion, Office 2010, esp. on a laptop, makes me want to beat the laptop on fireplug until it's rubble, and then head on across the country to Redmond, picking up a machine gun and grenades on the way.

[CentOS] How to patch a CentOS6 kernel
So I have a couple patches supplied to me by upstream in relation to a kernel bug[1], but I can't figure out how to patch the kernel. The CentOS wiki page discusses retrieving the kernel source[2], but doesn't describe how to apply patches. Instructions I've found apply to CentOS5, and RH has changed their kernel packaging since then. I've been banging my head on this off and on for quite a while, now. I've mucked with Gentoo and Debian packaging, but kernel RPMs are a new one for me...

I'm using fail2ban from EPEL since I didn't have any luck with the package
from RPMForge. I standardize on using EPEL if I can (but another admin
installed the rpmforge repo earlier).
I had to tweak the regex for the sasl filter to get it to match failed sasl
auth attempts though (EPEL package).
]# grep failregex /etc/fail2ban/filter.d/sasl.conf
# Option: failregex
#failregex = (?i): warning: [-._\w]+\[\]: SASL
(?:LOGIN|PLAIN|(?:CRAM|DIGEST)-MD5) authentication failed(:
[A-Za-z0-9+/]*={0,2})?$
failregex = (?i): warning: [-._\w]+\[\]: SASL

I believe this is exactly what I saw before I bailed on the rpmforge
fail2ban packages.

You don't need to set it to gamin ... the sasl jail (by default) is set to
polling (and this works with the EPEL package).

Re: [CentOS] fail2ban problem
I run strace -s 512 -f -F -p 9406
9406 is fail2ban-server pid
9406 poll([{fd=3, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}], 1,
3) = 0 (Timeout)
...
I think that the problem is not in server but the way actions "attached"
to iptables.
Python maybe?
Thanks again...

strace -s 512 -f -F -p e.g. strace -s 512 -f -F -p 19420 You can use -o to redirect the output to a file. That would be easier to check later then.

I remember I saw this behavior before. Mostly important thing is to find out if the enc/dec goes well. I was having this problem that triggers kernel to send out the icmp.

[CentOS] What about port 2048 for GRE(47) packaged in ip protocol
Hi, all: I'm playing with Gre Tunnel programming in centos 6. I wrote my program in these steps: a, open /dev/net/tun device and ioctl with TUNSETIFF, get fd to tun device, say "tun0"; b, create one socket and use it to set tun0's ip address, namyly SIOCSIFADDR and SIOCSIFDSTADDR; and then turn it up; c, create one raw socket to send things which got from the tun0 device to other machine, and to receive packages which should be feeded into the tun0 device; Finally, I ran the program in two machines, say MA and MB, synchronously, and set route info in MA and MB too. The last environment is like this: 10.0.3.1/24 192.168.0.31/24 192.168.0.124/24 10.0.4.1/24 -- MA --- MB -- tun0 eth0 eth0 tun0 When I ping MB in MA, and tcpdump eth0 in MA, I get: 15:06:39.712390 IP 192.168.0.31 > 192.168.0.124: GREv0, length 88: IP 10.0.3.1 > 10.0.4.1: ICMP echo request, id 28797, seq 1, length 64 15:06:39.713232 IP 192.168.0.124 > 192.168.0.31: ICMP 192.168.0.124 protocol 47 port 2048 unreachable, length 116 15:06:39.713667 IP 192.168.0.124 > 192.168.0.31: GREv0, length 88: IP 10.0.4.1 > 10.0.3.1: ICMP echo reply, id 28797, seq 1, length 64 15:06:39.713754 IP 192.168.0.31 > 192.168.0.124: ICMP 192.168.0.31 protocol 47 port 2048 unreachable, length 116 The 1st and 3rd lines is easy to understand, but what about the 2nd and 4th lines??? Is the raw package been sent up into gre protocol while caught by my program?? I have seen ICMP_PORT_UNREACH stuff been placed in ip_gre.c kernel code, but say it is "Impossible event". So, what's wrong, have I missed something in my program? Any suggestions are appreciated, thanks. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
