Re: [LUAU] Cheap linux router
The Linksys routers are targeted toward broadband cable/dsl users. I've heard the WRT54G can route a maximum 50Mbps between networks before reaching peak CPU utilization. I haven't tested it myself though. On Wed, 19 May 2004, paul wrote: Has anyone done any bandwidth testing on these routers? I would like to know how many Mbps these can push through them with an empty ruleset. I have been using a Soekris(http://www.soekris.com) box for my main router. Not very cheap ($200), but versatile, cool, and quiet. Most people have been able to push 17 Mbps through the net4501. Of course, it's processor is only an AMD 486. Always open to new ideas though for small,cool, and quiet routers. I am especially looking for one to substain 100Mbps throughput.

[LUAU] Cheap linux router
I've been playing around with the Linksys WRT54G and GS models. These sport a 200Mhs MIPs cpu and you can flash the firmware to run custom Linux builds. Check out http://docs.sveasoft.com/ and http://openwrt.ksilebo.net/ Linux 2.4.20 kernel, iptables, QoS iproute2+tc stuff all built in. Horror stories - you can flash the firmware and screw yourself so be careful. These Linksys routers range from $60 - $120 mailorder - retail. A really cheap router. No fans too, and only 12V.
Re: [luau] Speaking of hard drives
I know with western digital, you can use your credit card and ask for a replacement disk to be shipped to you first. Then you just use the same packaging to return your broken disk. Your credit card doesn't get charged unless you keep both drives =P. Ask Maxtor if they have something similar. On Wed, 14 May 2003, stimmy wrote: I need to RMA a hard drive to Maxtor, but they demand very specific shipping standards. So what I'm looking for are two hard drive inserts (top and bottom) for packaging, that are at least two inches in diameter. Personally, I think this is ludicrous, for an already broken hard drive. I mean, Newegg doesn't even ship to these standards. Anyone have something I could have or purchase at a small fee, in the Honolulu area? Thanks!

Re: [luau] java swing over ssh
This is just X11 forwarding over ssh. I'm not well-versed on the X11 protocol, but I think the 'swing widgets' would need to be somehow implemented in the X server. It's understandable that awt is, since X11 pretty much built on top of it. On Fri, 22 Nov 2002, Charles Lockhart wrote: > Sorry, should have been more clear.

Re: [luau] NFS ate my raid superblock
Yes, you'll want to watch your kernel messages as you boot up to see if it is an FS detection issue or a RAID detection issue. Having yourself on striped RAID-0 though leaves your guard low and your chin up. Here's the Kernel bootup portion of the RAID log.

Re: [luau] Samba as PDC, yadda yadda yadda
Vague, general questions will receive vague, general answers. On Tue, 22 Oct 2002, eXt wrote: > I'm trying to use my Linux box as a PDC for my LAN, but Im having problems > getting samba to even share files. Samba as a PDC is a fairly advanced step in Samba land. You have to create machine accounts for the actual Windows PCs: smbpasswd -a -m Then you have to create user accounts: smbpasswd -a I feel Workgroup mode is the way to go in a home setup. You want to generally create samba user accounts with the same name and password as they log into the Windows PC. Samba user/machine accounts are kept in a separate file from /etc/passwd. Look for the smbpasswd file in /etc/samba/ There are two smbpasswd files. The program and the user account file. > I'm also not able to share my WAN connection; my PCs get an IP from the Linux > boxs DHCP but no Internet... I tried using the "Server Wizard" included in > mandrake 9 but its not working... What errors do your PCs get when they discover "no Internet"? Do your PCs get a DNS server or a gateway address through DHCP? Run either "ipconfig /all" or "winipcfg" depending on the Windows OS. > And to keep asking questions, I cant get postfix to work!!!

Re: [luau] nfs and samba
Quite fine. Naturally, accessing the same file simultaneously through NFS and Samba may bring up some locking issues, so try not to do that. I find it generally easier to create windows usernames identical to the unix usernames, as it makes user mapping much easier between Unix and Windows. Most likely you'll run Samba in Workgroup mode, and if you create samba users (smbpasswd -a) with the same password as their Windows logins, it's fairly easy to maintain permissions. ...And hinting at advanced topics, running Samba as a domain controller, or possibly in conjunction with an XFS filesystem (Access Control Lists for finer grain file permissions). The www.samba.org FAQ will describe more, and refer you to yet more mailing lists =) > I'm considering sharing a single filesystem using both nfs and samba.
