We're stuck on RHEL 4.x, so we're currently working on a plan to live in harmony with .99 for another year or so. With that said, the plan is below. Let me know if you have any other recommendations. [ ]Convert to high-performance mode vice high-security to reduce overall resource usage. [ ]Implement iptables throttling for new connections to prevent denials of service. [ ]Covert from

We're running into an issue where sendmail is only receiving one e-mail, but after a client accesses the message via IMAP and moves it to another IMAP folder, the message duplicates but each message has different X-UID headers. Has anyone ever seen this type of anomaly before? Is it a bad IMAP client, or a known bug? Running 1.0.7 Thanks!

All, [version: dovecot-0.99.11-4.EL4.src.rpm] We recently experienced an issue that prevented all new IMAP logins from occurring. Although it appears that it was due to running out of available system file descriptors, I'm still not sure what the true root cause was as I can't replicate the same error in our test environment. The system file descriptor max was set at (per `cat

All, Is anyone using iptables (recent module), or any other alternatives, to throttle the number of new imap or pop connections per minute? We have some applications that like to login every second to pull mail using imap, so we'd like to protect the entire dovecot server from these applications. We've already made the change over to high-perf mode, but we still need some type of denial

This morning dovecot stopped allowing pop3 logins. In the logs I found the messages below Is there a config value for the max open files ? Dec 7 10:00:22 frigga dovecot: execv(/usr/local/libexec/dovecot/pop3) failed: Too many open files Dec 7 10:01:14 frigga dovecot: pipe() failed: Too many open files Dec 7 10:03:40 frigga dovecot: pipe() failed: Too many open files Dec 7 10:03:40 frigga

I have referred to the wiki and the RFC, but I still can't find the exact answer I'm looking for. From what I know, Dovecot uses the IMAP standard of 32 bit integers to uniquely identify messages. After a message is deleted from the mbox, can this UID ever be reissued to a new message or is that UID retired? What about after the 2 billion limit is reached? Thanks!

Hello All, I have a data with two columns. In one column it is date and in another column it is flow data. I was able to read the data as date and flow data. I used the following code: creek <- read.csv("creek.csv") library(ggplot2) creek[1:10,] colnames(creek) <- c("date","flow") creek$date <- as.Date(creek$date, "%m/%d/%Y") The link to my data

Hello All: Using the below dataset how can I make a barplot with Date(X) and NumEggs(Y) by Site. Then plot Temp(lineplot) It seems really simple, but I am having a hard time trying to do it by Site.

Its been a while since I tried dovecot on my mail server where I have quota issues. I am using mbox file format. There still seems to be a quota problem. I have only /var with quotas and basedir is under /usr (not quotaed). default_mail_env = mbox:~/mail/:INBOX=/var/mail/%u. I tried with mbox_locks = dotlock fcntl (1st set of logs below) and with mbox_locks = fcntl (2nd set of logs) dotlock:

note: whole function is below- I am sure I am doing something silly. when I use it like USGS(input="precipitation") it is choking on the precip.1 <- subset(DF, precipitation!="NA") b <- ddply(precip.1$precipitation, .(precip.1$gauge_name), cumsum) DF.precip <- precip.1 DF.precip$precipitation <- b$.data part, but runs fine outside of the function: days=7

R experts, I am working with a fairly large data set comprised of 563 rows by 116 columns including several different modes. I have been unable to read in the data set completely using the read.table function and the RGui (i.e. nearly half the total number of rows are missing from the data set along with the column names). The data does read in fully using Tinn-R's Rterm; however, at several

For this to work,

Greetings; I found pdf user manual which explains a few things that might help. However, for a ubuntu flavor, the various .conf etc files seem to be in /etc/nut. But this pdf says they are in /usr/local/ups/etc, and yes indeed there are some there, with the .sample files being owned by root, and the rest are user 503, whoever he may be. Are these just a sample storage in case one needs to

Hi everyone, I've posted some rpm builds of samba 4.11.3, 4.10.11 and 4.9.17 for RHEL/Centos 7.x (currently 7.7). The 4.11 rpms use the python3 and python3-devel rpms introduced in the standard RHEL/Centos repos at the same time as the 7.7 version. Comments and/or testing feedback would be most welcomed. http://nova.polymtl.ca/~coyote/dist/samba/samba-4.11.3

I realized that my last message about locking gave bad information -- or rather, very little information. Here's my setup: - Home directories and user login information are located on an Xserve running Mac OS X 10.2.6. Home directories are split between 2 different directories -- /Users and /Students. Home dirs are exported via NFS to the mail server. User login info is shared via LDAP

Greetings people; The section of drakeconf that pclos uses has two problems. First is several screens full of complaints about deprecated syntax in "/etc/udev/rules.d/70-nut-usbups.rules" at each reboot. So I pulled the current 2.5 svn trunk, then found I was missing quite a few build tools needed here that aren't used when building a kernel, currently running a 32 bit

Greetings all; Is it possible to set a logging option in one of the config files so that when we have a 1 second power bump, the date is included, both in the log, and in the -wall broadcast? We apparently have a substation regulator in the process of failing, and the recycle isn't normally slow enough to reset the clocks, but it killing one of my computers w/o actually causing a reboot.
