[CentOS] Opinions on bonding modes?
I am working on setting up an NFS server, which will mainly serve files to web servers, and I want to setup two bonds. I have a question regarding *which* bonding mode to use. None of the documentation I have read suggests any mode is better than other with the exception of specific use cases (e.g. switch does not support 802.3ad, active-backup). Since my switch *does* support 802.3ad, including layers 2,3 and 4 hashing, should I use mode=4? Or would one of the other modes be better for providing fail-over and link-aggregation, specifically balance-tlb or balance-alb. Any suggestions are appreciated.

Re: [CentOS] denyhosts configuration
Dave wrote: Hello, I've installed denyhosts on centos 5.3 trying to block automated attacks on ssh. It appears to be working in that entries are being added to /etc/hosts.deny yet the daily emails sent from denyhosts show only one ip being added perday when the total is many more than that. My config is below, i've gone over it and am not seeing what i missed. Suggestions welcome. I was also wondering if denyhosts can block other types of robot attacks such as smtp or port 80? It can deny access to any service that uses hosts.deny if you change it to ALL instead of sshd. It is configured to watch /var/log/secure, so if smtpd logs login failures there, then it can be used to add to the deny list. Apache does not use hosts.allow or hosts.deny by default. Some googling suggested this might be done with xinetd but I haven't tried it. BLOCK_SERVICE = sshd SYNC_SERVER = http://xmlrpc.denyhosts.net:9911 SYNC_INTERVAL = 1h SYNC_UPLOAD = yes SYNC_DOWNLOAD = yes I believe the IP entries being added are because you using the sync feature.

We can still SSH into the machine and restart Apache. This rectifies the issue. These are production boxes and subject to numerous connections, we are trying to isolate the trigger. However, the exact same configuration and applications being served under 5.2 exhibit no issue. I suspect it may be related to this bug, logged with the upstream: https://bugzilla.redhat.com/show_bug.cgi?id=497077 I was experiencing similar problems with an x86_64 server after upgrading to 5.3. While MySQL, Apache and PHP are installed SquirrelMail was not, nor mail services beyond daily logwatch emails. Since Apache was serving internal-only sites needed by only a few people in my department, I found that de-tuning the prefork section httpd.conf was an acceptable workaround. None of the other servers I have upgraded to 5.3 have exhibited this issue, but they are all i386 web servers only and do not mysql installed. Although they do handle 2-3 orders of magnitude more requests than the x86_64 server does. Thanks, Rick ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] Postfix Configuration Setup for 2+ domains
Hello, I have a client that wants to have a dedicated smtp sending host. But they have 2 separate domains then that don't want to have share IP address. The reasons from this is long and drawn out. Is it possible to setup postfix in a virtual host config, like apache for example, such that, domainA.com listens and sends on one IP address and domainB.com listens and sends on another address. This host is simply a email forwarding host, so no user accounts are on the server, they have about 5 servers serving websites for 2 domains and subdomains and want email coming from a common source for both domains (this will be the relayhost for the web servers). I have it setup to listen to 2 ip addresses but as of now I get: 220 smtp.domainA ESMTP Postfix on both addresses. Is there a way to have one address show as: 220 smtp.domainA ESMTP Postfix and the other: 220 smtp.domainB ESMTP Postfix More importantly, email send via 1 should look like it came from that domain and email sent to the other look like it came from its domain.
