Re: [CentOS] Dual WAN on EL8 desktop.
I think you need policy routing: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/configuring_and_managing_networking/configuring-policy-based-routing-to-define-alternative-routes_configuring-and-managing-networking https://doc.lagout.org/network/inetdoc/Policy_Routing_in_Linux_ENG.pdf Although it may be tempting to use some sort of round-robin, it would be safer to have specific rules based on the destination, so for example you send all web traffic to one ISP and add exceptions to route specific traffic to the second ISP (e.g. streaming platforms), with each rule having a "backup route" to the other ISP.

[CentOS] Disable specific LUN on a SCSI bus
Hi all, do you know if there is a way at boot time do disable specific LUN's on a SCSI bus of a particular controller? I'm trying to write an udev rule, but it seems that the system ignores the "vendor" model/name of the controller... For example: I want to disable /dev/sdb; so I gather some information with udevinfo -a -p /sys/block/sdb and I try to use them to write /etc/udev/rules.d/10-custom.rules ID=="?:0:1:0", BUS=="scsi", DRIVER=="sd", SYSFS{model}=="DDYS-T36950N", SYSFS{vendor}=="IBM ", OPTIONS="ignore_device", OPTIONS+="last_rule" I put the "?" on the ID field because I know that the order of the controller can change (a kernel update could trigger the switch); also I tried with and without the spaces at the end of vendor and model: no change Where am I wrong? It is a different way of doing this? TIA Ciao Lorenzo ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Then [updates], which I'm currently rsyncing from a remote mirror. And I think I'll do something similar with [extra], which only leaves [rpmforge] (but I won't cache that :oD).

Fedora is not an option for most business people who rely on their laptops every day. Torture is installing the latest Fedora every 6 months and hoping something doesn't break. Some would say Fedora users are nuts. I'm actually using CentOS on 2 laptops, and I have really few issues: on the newer one (a Lenovo) the only thing that doesn't work is sound (I know the newer alsa drivers would work, but I'm too lazy to install them: I'll wait for the updates) but it isn't a big deal: I'm using it for work, and I don't need sound My old crappy asus instead is just for watching movies attached to an external flat lcd tv and it's doing his job wonderfully (even if it has some issue with the integrated monitor) So maybe I'm nuts, but I'm happy with not having to reinstall everything every 6/12 months. :) Lorenzo ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] forcing device to USB HDD

James, I was looking exactly for the same thing. I don't have programming skills, but I can do debugging and testing... So if you want we can join our efforts on this project.

Re: [CentOS] restrict network access
Arne Pelka ha scritto: Hi, I have two pc using centos 4, these machines need only access to the (big, class b) local network. Because of security reasons the network access should be restricted to this local network - mainly the users of these pc should not be able to access webpages outside of the local network. My problem is, that I have no own centos repository and therefore these two pc need access to the centos mirrors to get updates. What would be the best way to restrict the network access to the local network and allow the access to some external addresses (a centos mirror and maybe some other servers/websites). I was thinking about iptables but I'm not very experienced in this questions - maybe there is an easier way. The configuration with iptables seems to be very complex, I was skimming through some tutorials and the man pages. In thanks and with best reagrds, Arne I would setup a box with a proxy (eg. squid) and grant full internet access only to that box. On the other boxes either remove the default route, or block on the router/firewall internet access. On the proxy you can easily configure proxies for other services too (eg. pop3/imap) and filter out traffic from/to Internet at will (dansguardian/squidguard); on the pc's you just need to setup the proxy on yum.conf to enable yum updates and (if needed) configure the proxy on your browser, you email-client and so on. I'm still on my way to figure out how to implement a simple yum cache/proxy; as soon as I have news I'll let you know, as in that case you don't need anymore to setup squid and the proxy box will be really trivial to setup.

[CentOS] Zip password recovery

If it understands the concept of mirrors, than yes, it is exactly as I envisioned it :) I just packaged it and you can provide it with a list of mirrors although it could have handled it transparantly instead of requiring a list upfront. You can find a temporary package here: http://dag.wieers.com/attic/RPMS/http-replicator-3.0-1.el5.rf.noarch.rpm but it will be available soon on the mirrors. Even though it is tagged el5, it should work fine on EL4 or EL3. Let me know if you have any problems. Thanks Dag for the packaging; I'm on my way of testing, and I find that dealing with mirror lists isn't straight forward at all. I will try to understand if is possible to modify the source so it only caches rpm files on a flat format and it compares only the file name and not the full path. Also I have to understand if it is possible to add ftp support.
