similar to: auth: Warning: DNS lookup took 1.550 s

Thanks for your comments. I understand as DNS uses UDP that there could be some DNS queries which might get lost if the CPU or network is too busy but the thing is that this server is not so busy really. It has 2 cores with 4 GB of RAM and the CPU averages to 2% usage. The network averages to 1 Mbit/s traffic and there are around 600-700 processes running for 1100 mailboxes. Note here that this

how do you come to the conclusion that it matters how busy "this server is"? jesus christ you are asking *remote servers* for their answers and the request as well the answer passes different routers, ISP's and likely a *chain of forwarders* until you don't recursion at your own and even if you do you have no control how overloaded one of the networks between you and the

The law in France (Code P?nal, article 227-24) states that a public network is not allowed to broadcast messages containing violence, pornography or any content contrary to basic human dignity, which is theoretically punishable with three years of prison or a 75.000 ? fee. So any network

As another poster has commented, a slow DNS response may not be anything related to your setup, but caused by upstream DNS service. Slow DNS response or timeouts is not

Hello, I am wondering which variant is more secure for user authentication and password scheme. Basically I am looking at both variants: 1) MD5-CRYPT password scheme storage with CRAM-MD5 auth mechanism 2) SHA512-CRYPT password scheme storage with PLAIN auth mechanism In my opinion the option 2) should be safer although it is using PLAIN auth mechanism. Of course I would always use STARTTLS and

Hello, I've recently discovered a persistent issue with rpanel when running R.app (2.6.1) on Mac OS X 10.4.11. tcltk and rpanel load without any apparent error, and the interactive panels appear to work as expected, however upon closing the panels rpanel has created I get catastrophic errors and R crashes completely. For the most part R manages to crash with dignity and work can be saved, but

how come only 1 out of 3 versions of wine actually gets built for etch? i mean i understand that the packages get built by different people so theyre not updated synchronously but ubuntu, suse, mandriva etc are all up to date at 0.9.60, whereas the latest etch package ist version 0.9.58, TWO versions behind !!! no fair! i mean cmon! debian is just as mainstream as the rest of em, so give us a

Hello, We are getting a baffling problem with a samba mounted drive on Redhat, mounted from a windows box. We cannot always see files in the mounted directory with ls or perl. The directory has 237 files in it. We sometimes see 197 files with ls. Sometimes we see nothing. This can happen from one try to the next (i.e. run ls, see the files, immediately run ls again and see nothing). We have

Hello-- I submitted of extensions.conf that contains my "telemarketer torture" menus, last week sometime to the mailing list. I got back a note from the mailing list machinery, stating that it was too big, and would be subject to approval. No such approval came, I guess. Either I missed it, or it didn't rate, or the moderator just plain hasn't gotten around to it yet. So, I

(Sorry for cross-posting; I'm not on either ext3-users or linux-xfs, but I thought both lists might find this interesting. CC me with any replies or questions. Thanks.)

Some listees might be interested in some testing I did the other

Just looking through the 2.4.20pre changelogs, I see there's been a bunch of Ext3 patches since 2.4.19. I'm keen to take advantage of any bug fixes and performance improvements, but am nervous about using 2.4.20 until it's completed its release cycle. Is there any way to get a patch just containing the Ext3 changes? Are there any changes since 2.4.20 that are very important, either
