Greetings, This is not a problem with Samba as I see it but I am hoping that others on the list have some ideas for working around the issue. Our central computer services group scans all the campus networks using Nessus and some custom rules to look for security problems. What I am seeing within my college is my Samba PDC getting beat-up when the scans go though. They scan a block of PCs

Hello, we have just observed a rather annoying behavior one of our servers. Specifically, when writing data to a file on an ext3fs filesystem at around 1.5 MB/sec, network connectivity suddently started to show signs of lag. The ping would spike up to ~1 second every 5 seconds or so. This affects the server in question and all hosts routing traffic through it (i.e., it's not a userland-only

I am having a bizarre problem with a samba server here at Edward Waters College. Hopefully someone can give me insight to inform me what to look for. samba version = 3.0.14a SuSE 9.1, up-to-date-via-apt AD/W2K3 (no sp) Winbind using RID algorithm server purpose: HOMES, DESKTOPS, MY DOCUMENTS, PROFILES Quotas are: ON Filesystem: Reiser HW Raid 5 (MegaRaid) 4 logical processors (dual+ht). uname

I have a suggestion about the heartbeat and the way that "downed node" detection works. There are occasions where a node is up, and for whatever reason, I need to power cycle it (for instance, a frozen process, etc). In these instances, my other nodes are unable to perform file system operations until the heartbeat period expires. This ends up being somewhere around 30-60 seconds (this

Hi all, I've had an interesting use case come up which - to cut the story short - one way to solve the problem I am looking at may be to replicate a small number of mailboxes to a third remote server. I've currently had replication running between my main dovecot machine and another remote VM for some time and working well (so I'm not new to replication and I've got a good

Dear All, we are experiencing severe problems with Samba 2.2.0 (with quota support) running on a dual processor (400MHz) Sun E450 running Solaris 2.7. This is used as a central file server for student diskspace, accessed by approx 1200 PCs running NT 4. Up until recently we experienced some, what we assume to be, loading issues with connections during the middle of the day being slow.

So far we've tracked down four bugs using _GLIBCXX_DEBUG, all of them quite subtle and some of them leading to serious problems like heap corruption. But we've also discovered that compile time can skyrocket in some cases as the library does its checks. The standard library complexity guarantees don't apply with _GLIBCXX_DEBUG. Therefore, we should figure out if we want to enable

I'm trying to use Wine to run a program called heavy weather - its a windows only program that interfaces with a weather station that I have through a serial port. I was able to get the program up and running with wine. Then, I couldn't get it to connect at all to the weather station. After much too long, I finally realized that the problem was that my permissions on /dev/ttyS0 were too

Once the operators restarted jboss, the system''d be normal again (sometimes for weeks) until the next incident Since we moved the app from a v440 running Solaris 10 8/07 to a t2000 running Solaris 10 5/08 the problem started to happen more frequently (2-3 times a week).

We run a Hosting farm behind a bridge/iptables firewall setup running Gentoo with kernel 2.4.20-gentoo-r6, connected to a dual 15Mbps international internet pipe / , as this: Net Pipe --------- eth1 Bridge/Firewall eth0 -------- Internal Hosting Network lately we have been looking at htb to somehow control excessive usage from the users behind, but in our implementation there seems to be an

By the time we had only a few CentOS 5 boxes left, they were performing so badly as to be effectively worthless. What we observed in parallel to this upgrade process was that the read latency on our NetApp device skyrocketed. This in turn caused all compute jobs to actually run slower, as it seemed to move the bottleneck from the client servers' OS to the NetApp. This is somewhat counter-intuitive: CentOS 6 performs faster, but actually results in net performance loss because it creates a bottleneck on our centra...

The raid check starts out fairly fast (20000K/sec - the limit that's been set), but then quickly drops down to about 4000K/Sec. dev.raid.speed sysctls are at the defaults: It looks like some pretty heavy writes are

Our Samba server running on CentOS 5.1 (upgraded from 5.0) with Samba 3.0.25b-1.el5_1.4 has been in place for about a year and a half. We had no issues till about 2 months ago. This may have coincided with the upgrade of CentOS 5.0 to 5.1 (which would have brought a new Samba version with it). Anyway, the server will be fine and snappy for a week or so, then out of the blue, nobody can
