Hi, I am running two hosts with xen-4.0.1 and dom0 kernel 2.6.32.41. The two hosts are connected to a Gigbit switch. Then I use iperf to measure the bandwidth and got the results of 200Mbit/second, which is only 1/5 of the available bandwidth. Then I boot these two hosts using a vanilla kernel of 2.6.32.34. The iperf reports 937Mbis/s, which is very close to the available link bandwidth. So why the pvops...

Hi, In populating our racks with several gigbit switches over the next few days, i'm wondering this: Is it over-engineering to seek out 550mhz rated cables over the typical Cat 6 250mhz rated cables? I've been advised (if you can a salesperson's words advice, heh.) that 250mhz is enough to handle traffic up to 10GB's. Should I...

...he lease time is only three hours so everyone was affected reasonably early). This morning, however, the logon scripts would not run until I changed the node-type back to h-node. I have found some information regarding timing issues with VPN's but this is plain old local logins (server has gigbit nics, going through a gigbit switch, clients have 100baseT). There was one change but I can't really test that until tonight: Samba was rebuilt with the hide-special-files patch - https://bugzilla.samba.org/show_bug.cgi?id=2514 , which doesn't seem like it should cause a problem. Any...

Is Samba (1.19) incompatible with FoxPro? We have tried to network a database package (FoxPro is the underlying DBMS) by putting it in a Samba share. The database starts up and you can browse the tables, but it looks as though FoxPro's record locking system causes the entire share to be locked, so that further access to the shared drive (both in FoxPro and in the Windows98 Explorer) is

I've looked on the 'net and found some references to poor performance but I haven't seen a solution. My environment: Linux: SuSE 9.2 Pro AMD64 Windows: Windows XP Pro (32-bit) on an Athlon64 Networking: everything connected with GoC. >From the Linux box, I want to basically back up some stuff from the Windows box. To do so, I use the following: smbclient //winbox/share

Hi all, i have a question. I''m going to setup a Xen server for a client. It''s going to serve about 25 clients. It''s a Athlon 64 3200+, which currently runs Debian i386-stable and xen 2.0.7 until Xen 3.0 is stable enough, and then i''m gonna replace it with Debian amd64-stable and Xen 3.0. The Xen dom''s consists of: Samba , file printer sharing most

...one night I used crossover cable between eth2 and Dmz and had same problem (slow or no connections from outside networks on the net) I could get successfull high speed connections to the Dmz server from the internal lan to the Dmz server. The second night I thought since the Dmz server has a gigbit nic and shorewall eth2 did not that this may be the trouble. So I put a Cisco 10/100 swich between shorewall eth2 and Dmz servers single nic 10/1000. And I came up with same trouble. Since the server has to be up 24/7 I have it back out on the firing line (net). Can the list provide me with...

Hello all. I have 15 or so CentOS servers (now v4.4, I will upgrade them all to 5 when it comes out) and a few windows machines. I am looking to implement a network backup solution using Amanda. I will be backing up 200 gig or so to start, but that will grow. Does anyone have any recommendations on tape drives that will work "out of the box" with CentOS? Thanks, Joe
