Hello, I?m sending doveadm ?kick? commands to doveadm-server via the doveadm protocol. When ?kick? sends back a NOTFOUND error, though, it?s sending back additional output. strace shows: write(3<UNIX:[3158354->3156665]>, "\t\tkick\tmyssltest\n", 17) = 17 ... read(3<UNIX:[3158354->3156665]>, "\n-NOTFOUND\n\n-\n", 8192) = 14 Going by the protocol

Hello, Currently working on migrating our existing directors from 2.1.13 to 2.2.10. In 2.2.10 when issuing the logout command on an unauthenticated connection, the connection is closed before the server sends the BYE line to the client. The new version works as expected with a non-secure connection. I will include the strace output from the imap-login process that shows the connection closing

I did a bit more digging, and the issue appears to manifest only when doveadm sends back an error code. Here is a ?user? and a ?kick?, both of which fail with error codes: > echo -ne 'VERSION\tdoveadm-server\t1\t0\nD\tharry\tuser\nD\t\tkick\tharry\n' | nc -U /var/run/dovecot/doveadm-server | xxd 0000000: 2b0a 0a2d 5553 4147 450a 0a2d 0a0a 2d4e +..-USAGE..-..-N 0000010: 4f54 464f 554e

I have a largish dataset (1025) with around .15 of the data missing at random overall, but more like .25 in the dependent variable. I am interested in modelling the data using quantile regression, but do not know how to do this with multiply imputed data (which is what the dataset seems to need). The original plan was to use qr (or whatever) from the quantreg package as the 'fitter'

I encountered a problem with dom0 when rebooting and running an intel gigabit card using the pro/1000 driver. When the system tries to shut down I get the following output of an strace command : ......... 17:10:49.063616 socket(PF_INET, SOCK_DGRAM, IPPROTO_IP) = 3 <0.000029> 17:10:49.063689 ioctl(3, 0x8913, 0xbffffc80) = 0 <0.000018> 17:10:49.063751 ioctl(3, 0x8914, 0xbffffc80) =

Hi Jones, many thanks again four your help and your time. Thanks for the patch too - I'll check it up. On my Ubuntu, there is a Samba 4.1.6. I'll install the samba source package, and will try to apply the patch, then - I hope - the package will be compiled as well. I'll notify to you about the result. (First, I need to upgrade that server.) Thanks again, Ervin On Thu, Apr

According to this bugzilla entry, bug 6870 has been fixed as of at least version 3.5: https://bugzilla.samba.org/show_bug.cgi?id=6870 However, I assert that it is present in 4.2.10, which ships with Debian Jessie. On my home network (IPv4 and IPv6), a box with Samba 4.2.10 with IPv6 disabled (via sysctl), will fail to contact a DC because the IPv6 connect fails immediately before the v4

I apologize in advance for the simplicity of this question. I use R 2-3 times a year, and I seem to forget more in the intervening months than I learn during my days of panicked reading.... I HAVE tried looking at the help resources; I'm just not very good at understanding them. I have a dataframe with 18 observations of 5 different things, and a second dataframe with and estimate for those

Hi, We did some performance test and found the create/delete files performance of btrfs is very poor. The test is that we create 50000 files and measure the file-create time first, and then delete these 50000 files and measure the file-delete time. (The attached file is the reproduce program) The result is following: (Unit: second) Create file performance BtrFS Ext4 Total times:

Some more information: the issue has just occurred, again on an instance without the "service_count = 0" configuration directive on pop3-login. I've observed that while the issue is occurring, the director process goes 100% CPU. I've straced the process. It is seemingly looping: ... ... epoll_ctl(13, EPOLL_CTL_ADD, 78, {EPOLLIN|EPOLLPRI|EPOLLERR|EPOLLHUP, {u32=149035320,
