Anyone have experience with these kernel parameters? I can't find a whole lot of info on them. I have a situation where I'm trying to stress test a server, dual proc quad core with a tomcat application that is really fast. We can get it to about 60% CPU usage, and processing about 1,350 requests a second but we can't get much past that. It seems we are maxing out the sockets on the

Hi all, storing e-mails (using postfix) via dovecot-lda fails and I assume this is related with a auth_socket configuration problem. But I am at a dead end, so perhaps anybody has got a hint for me: This is dovecot-2.0.8 on Solaris 10: 10-auth.conf and its include: ----------------------------- ... userdb { driver = static args = uid=104 gid=104 home=/some/path/%u } Relevant parts of

Hi all, I have a setup of some nodes running Dovecot 2.0.13 and Postfix 2.5.6 with storage in NFS and authentication happening with PAM. Poking around in the wiki, I tried out different possibilities but now I am stuck -- and are hoping for your (enlightening) comments and tips. My planned setup for IMAP and LMTP is like this: IMAP ==== 1. A loadbalancer directs new sessions to a

Dear all, I am trying to setup Dovecot with GSSAPI support. For testing purposes gssapi is the only method allowed for login. As I cannot login to my mailbox, I'vo got two questions about the following log entries: dovecot: Info: auth-worker(default): passwd-file /dovecot/store/db/test-userdb: Read 3 users dovecot: Info: auth(default): new auth connection: pid=3915 dovecot: Info:

Hello everybody, I''m new to Xen so forgive me if this is already well known issue. I''m using Ubuntu server 7.04 (feisty) with Xen 3.0.3 Everything works perfectly, apart from networking in NAT mode. With bridging it works, with NAT it works, well, quite strange. Namely, pings go through and name resolution works. But when I try to use anything substantial, then

I have the need to know how many connection the server has, i run this command but i don't know how to sum all the results and get a final number. any ideas? netstat -an | grep -E 'tcp|udp' | awk '{print $6}' | sort | uniq -c | sort -n ?? 1 CLOSE_WAIT ?? 1 FIN_WAIT_2 ?? 1 LAST_ACK ?? 1 TIME_WAIT ?? 4 SYN_SENT ? 15 ? 37 LISTEN ? 44 ESTABLISHED

Hello everyone I have recently reported problems reading a certain directory from an NT server on this list (and speculated in causes). I have a few workarounds and now I'm looking for some feedback on what the proper fix is and for people to test if my patch works for them. Please test smbfs with and without the patch on the directory in this zipfile (all files are empty):

Hi there, I have some DDOS(?) attack on my router going where my apache HTTP server is flooded with short-timed connections from some host. This results in LOTS of sockets in TIME_WAIT/LAST_ACK/CLOSING states and eventually I'm out of mbufs, which, consequently means I can't even connect to the router from LAN. The kern.ipc.nmbclusters is 2560, (I guess high enough for router with

Hi, I didn't know where to post this one so I'll start off with you guys and then try Postfix if I'm barking up the wrong tree! Having set up my mail server (Dovecot/Postfix), users are experiencing long delays (a couple of minutes) when sending mail from mail client such as Thunderbird - this increases with attachments. Having had a brief discussion with someone, they mentioned

For example I think

Hi! Here's a patch that allows Linux smbfs to list large directories (i.e. > 100 items) when talking to an OS/2 server. There is a misunderstanding about the flags sent in the FINDFIRST request which causes the OS/2 server to indicate an EOS (end of search) in the FINDFIRST response, even when there are more items to be listed. The result is that smbfs will display only the first ~120

Hi, I have > 11 TB hard used Mailstorage, saved als maildir in ext3 on HP EVA. I always wanted to make some mesurements about several influences to the performance (switch to ext4, switch to mdbox), but I never had enough time to do that. At the moment I *need* more speed, we have too much waitI/O on the system and I already used all other performance and tuning-tricks (separated cache,

Hi. I have a Windows machine (XP/SP2) which i want backup to a Linux machine (named "Pippi") using rsync. I have cwRsyncServer running on the Windows machine (10.10.10.90). When i start rsync from the Linux machine after a while rsync stops - as far as i understand it because of a network timeout. > io timeout after 60 seconds -- exiting > rsync error: timeout in data

Hello, I try to write a bash skript and I want to use the variables from my bash skript into R. Ist that possible? My bash skript creates lots of *.data files. I want forward these files directly into R (in x.data.bz2), so that R creates a few data automatically also in PDF. For example: bash created files: hello.data , world.data how R created these files in pdf? please look my plot.R

Hi, I''m running into a strange issue where one mongrel will sometimes develop hundreds of CLOSE_WAIT TCP connections, mostly to apache (I think -- see sample lsof output below). I haven''t had a chance to get the mongrel with this behavior into USR1 debug mode yet. I didn''t catch it in time. This happens a couple times a day on average at seemingly random times.

Dear All: I have Icecast2 and IceS2 successfully built and installed on a Debian 3.0 system. After tinkering with the config files, both applications are running and seem to be talking to each other without problem. However, when I try to connect with a client, I run into problems: with Winamp 2.8, I get an [HTTP/1.0 200 OK] message, but then the stream is apparently dropped before buffering.
