Does that mean you've been using Mutt? :-) How good is it? Any comments on the differences (productivity, mail filtering, etc) from the graphical mail clients? Why do you use it? Thanks Leonardo

Samba config for Windows on VMWare
by Mark Hull-Richter 27 Mar '07

27 Mar '07

I know this is a little off topic (not as usual, dammit!), but I figure at least one of y'all can handle this one. I have tried to configure my CentOS4.4 Plus desktop for samba sharing with the VMWare Windows that runs on it. However, no matter what I've done so far, I can't get the Windows to recognize this machine as a legitimate network destination. Here's my samba config file: [root@mhullrichter shared]# cat /etc/samba/smb.conf # Global parameters [global] server string = Samba Server security = SHARE log file = /var/log/samba/%m.log max log size = 50 socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 printcap name = /etc/printcap dns proxy = No idmap uid = 16777216-33554431 idmap gid = 16777216-33554431 cups options = raw [homes] comment = Home Directories read only = No browseable = No [public] comment = Data path = /home/mark force user = mark force group = users read only = No guest ok = Yes [printers] comment = All Printers path = /var/spool/samba printable = Yes browseable = No It passes testparm, the smb daemons are up and running: [root@mhullrichter shared]# psg smbd root 2751 1 0 11:44 ? 00:00:00 smbd -D root 2752 2751 0 11:44 ? 00:00:00 smbd -D I noticed that neither the nmbd nor winbindd daemons are running - dunno why, the startup showed [ OK ]. But in the Windows, it can see my machine but can't connect to it - what am I missing?

SMP kernels and top output
by Bisbal, Prentice 27 Mar '07

27 Mar '07

Hi, everyone. I'm new to the list. This question may have come up before, but I couldn't find an answer to it by searching the centos website. Could be I was using bad keywords for my search. I have 3 HP xw9300 workstations (dual AMD Opteron 64-bit processors) that I'm upgrading from RHEL3WS to CentOS 4.4. I've upgraded two already, with one left to go. On the system with RHEL3WS, 'top' shows statistics for each processor and what processor # each process is running on. On the systems running CentOS 4.4, the output of 'top' looks like that of a uniprocessors system - there are no statistics for each processor and it doesn't show which processor each process is running on. However, /proc/cpuinfo shows the two processors. Does this mean that my OS isn't seeing the second processor, or has the behavior of top changed between the two OS versions? Is there any way that I Can verify that both processors are being used? -- Prentice The contents of this communication, including any attachments, may be confidential, privileged or otherwise protected from disclosure.

Quick review: when I finally got the system into init 3 state, I ran the nvidia installer, it compiled the driver on host and said everything wa fine. I have no clue what the second one means or why it would be happening. The two errors are not directl connected to each other and appear with a random number and type of message in between. mhr PS: Jim, your reputation is safe and secure, at least for me.

I'll fix this at some point, probably after I get samba to let my Windows VM talk to my disk drives....

Question about rebooting and iptables rules persisting
by Preston Crawford 27 Mar '07

27 Mar '07

So I use Samba on my home network. I open the samba ports in the GUI tool for CentOS 4. Here is the problem. Every time I reboot I'm forced to run system-config-securitylevel to get firewall ports open again. So like if I reboot samba won't work. I go into that tool either via command line or via the GUI and I simply click "ok" and samba is suddenly open. Does anyone know what is happening? I've tried iptables -save or whatever. Nothing seems to work in getting these ports to be open on reboot. Preston

I've been using AIT for a while now and have had no problems with it. AIT-4 would suit you well with its 200GB native capacity. All SCSI drives should be supported well in CentOS.

network redundancy via two nics, two routers?
by Jeff Potter 27 Mar '07

27 Mar '07

Hi List, I'm trying to configure two switches to provide redundancy (i.e. in case one switch goes down), and am wondering if there is a standard way to configure a CentOS box to use different gateways in a bonded interface, depending upon which physical nic is being used? A bit more detail might help answer the "And why do you want to do that?" questions... - Switch 1, Port 1: has an uplink to upstream provider, and is in VLAN-1 - Switch 2, Port 1: has a 2nd uplink to upstream provider, and is in VLAN-1 - Switch 1, Port 25+26 are trunked (link aggregation; depends on your terminology; these are procurve 2600's) and connected to Switch 2, Port 25+26. All vlans configured run on the trunked link, with tagging. - Uplinks to provider are running HSRP. Upstream provider creates a virtual IP (say, 2.2.2.1) that is the gateway to the outside world on one of the links, randomly. - Server A is connected to Switch 1, Port 2 on eth0; and Switch 2, Port 2 on eth1. Server is assigned an IP address, say, 1.1.1.2, inside VLAN-2 (1.1.1.0/24) - Server B, C, etc. exist in different VLANs. (Just saying this so as to avoid the suggestion of "don't use vlans" because that would make this mess go away, but create a security problem.) - Switch 1 does light routing. For VLAN-2, it is listening on, say, 1.1.1.254. - Switch 2 also does light routing. For VLAN-2, it is listening on, say, 1.1.1.253. So, Server A's eth0 should use 1.1.1.254 as its gateway; and Server A's eth1 should use 1.1.1.253 as its gateway. The HSRP link will create 2.2.2.1 and an associated MAC address on one of its links; the two switches will throw the packets to the HSRP link on the correct switch. It doesn't matter which router (1.1.1.254 of 1.1.1.253) is used, since they will both route packets to the appropriate VLAN. If one of the switches goes down, the surviving HSRP link will claim the virtual IP (2.2.2.1) and the switch will receive an arp to let it know to update its arp table. (I've also set mac and arp timeouts to 1 minute.) So, the question remains... is there a way to tell linux that, given a bonded interface, the gateway for one physical nic is X while for a second physical nic it is Y? (Bonding can be active/standby.) (If I had tons of $'s; I would just go buy some Cisco gear that's capable of creating a virtual chassis and be done with this. I don't have tons of $'s. If there are other ways of configuring this; I'd love to know; but from everything I can gather, passing the various VLAN traffic between the two switches (via tagged-VLANs on the interswitch connection) seems the only viable solution. Or should I really be looking at XRRP? Or Stacking? But that's a different list...) How do people normally do this? (This seems too complicated to be right.) best, Jeff
