[OT] Network switches
by Scott McClanahan 27 Mar '09

27 Mar '09

I'm looking to acquire a few new core switches for our network which would be a major upgrade from the cheap unmanaged things we currently have. Basically, just users, servers, and other simple network devices will be plugged into them but I'd like to start doing some testing with iSCSI for various non-production reasons. I have no allegiance to a particular vendor although I do have a Cisco background. I'd like them to be at least 10/100/1000 (no need for power over ethernet) and include many of the features that are most important to me in a managed switch, including: * vlans * mstp or some well established form of per vlan spanning tree * acl's * port mirroring or what cisco calls span sessions * snmp * ssh enabled remote management * support w/ updates and bugfixes I need at least 48 ports per device and obviously would like them to be "fast". Most importantly, I'd like to know what you guys prefer as operations dudes and what pitfalls to avoid. Also, are there other features you folks would demand to have in your switches that I haven't mentioned? I can provide more information if you'd like. Thanks. Oh, cost is sort of an issue (small/medium sized business) but right now insight from you guys is what's important and I can work out the cost issue later. Thanks again.

Dell 120 GB 5400 RPM Encrypted Serial ATA Hard Drive
by Agile Aspect 26 Mar '09

26 Mar '09

Hi - I've been asked to re-partition a Dell 120 GB 5400 RPM Encrypted Serial ATA Hard Drive and install CentOS 5 on the new partition. It's a Dell Lattitude E5400 laptop. Is this even possible with encrypted drives? Does CentOS 5 need special drivers? Any help would be greatly appreciated. -- Agile -- Article. VI.

CentOS 5.2 and wired Ethernet on a Macbook Pro?
by Scott R. Ehrlich 26 Mar '09

26 Mar '09

I recently installed CentOS 5.2 64-bit on a partition on a MacBook Pro 17 inch. It installed just fine, but wired Ethernet is not available. lspci shows it as nVidia...unknown. Is it possible to get wired Ethernet running on this laptop under CentOS without having to create a virtual machine installation of CentOS? If so, what is the magic? Thanks. Scott

Monitoring IP masquerading on LVS load-balancing
by David Dyer-Bennet 26 Mar '09

26 Mar '09

I've got small numbers of connections moving through a load balancer configured in NAT mode. So I've got an iptables table called "nat", which has in it a line "-A POSTROUTING -o eth0 -j MASQUERADE" (lan connect is eth0, private lan inside the cluster is eth1). The load balancer is working; connections made to the virtual ip on that host do get routed to one of the real servers behind this load load balancer. But I want to observe the connections on the load balancer. My first attempt was to use netstat with the --masquerade switch. This produced the result "netstat: no support for `ip_masquerade' on this system." Consistent with this, there is no /proc/net/ip_masquerade. On the other hand, the load balancer *IS* working; those connections *are* getting NATted and routed. Also, lsmod shows varous relevant modules loaded: iptable_nat 40773 1 ip_nat 53101 2 ipt_MASQUERADE,iptable_nat ip_conntrack 91237 5 xt_state,ip_conntrack_netbios_ns,ipt_MASQUERADE,iptable_nat,ip_nat nfnetlink 40457 2 ip_nat,ip_conntrack ip_tables 55329 2 iptable_filter,iptable_nat x_tables 50377 7 xt_state,ipt_REJECT,xt_tcpudp,ipt_MASQUERADE,xt_multiport,iptable_nat,ip_tables So, netstat just isn't somehow the right monitoring tool, right? So what is the right monitoring tool? I need to know the source IP and real-server IP of connections being handled by the load balancer. I don't need a lot showing exactly how each one was handled, but I'd like to be able to determine the state of any connection currently active. How can I do this? -- David Dyer-Bennet, dd-b(a)dd-b.net; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info

Hello again. You were kind enough to give me this advice last December. I've another holiday approaching and thought it was time that I got this sorted. Unfortunately, I'm not sure that I can do this, so I'm asking your opinion. My router is a Netgear DG834G. I can create a service, tell it which ports to open, and say which local IP I want it sent to. However, I can't see any way to set the port to which it should be forwarded as anything other than the incoming port. IOW, I can enable the new service Ext-ssh, which accepts incoming traffic on port 22022, and direct it to my server on 192.168.0.40, but I can't see how to make it send that traffic to port 22 on the server. Am I totally misunderstanding this? Really all I want is to be able to log in to the server if I get an email alert that there is a problem or security updates pending. If I can get this sorted, I'll look again at how to route the IMAP mail through the tunnel too. Anne -- New to KDE4? - get help from http://userbase.kde.org Just found a cool new feature?

Hi There is a broken link in the documentation of CentOS 5.2. I was reading about e-mail and when you follow the link from POP (24.1.2.1 in Deployment guide) to IMAP, you got the following message: "Not Found The requested URL /docs/5/html/5.2/Deployment_Guide/s3-email-protocols-imap.html was not found on this server."
