Problem communicating from server to client
Hello, I've set up a tinc "server" named "spitzer" in proxy arp mode, and a client "inspiron" that connects to it. inspiron runs tinc 1.0.16, spitzer runs 1.0.11. Ping and ssh from inspiron to spitzer and other hosts in the network (via spitzer) works fine. Ping and ssh from other hosts in the network to inspiron works fine (i.e. going through spitzer works

NFS4 over tinc hangs
Hello, I am experiencing system hangs when running NFSv4 over a tinc VPN. I don't know if the problem is with NFS or tinc and would appreciate any suggestions on how to narrow down the culprit. Unfortunately I cannot simply run NFS directly over TCP -- the participating systems are connected only over an open network. The configuration is as follows: I have a master server

Semantics of "smb ports = 0"
Hello, The qemu emulator has a feature to fork a samba instance for file sharing with the emulated hosts. It communicates with smbd over stdin. The generated configuration file contains a "smb ports = 0" directive to prevent smbd from listening to any ports. Unfortunately, with at least Samba 3.6.4 this causes a segfault instead: [0] vostro:/tmp/qemu-smb.6836-0# smbd -i -s smb.conf

Use proxy only for some nodes
Hello, Is there a way to tell tinc to use a "proxy = exec ..." for only some specific node? Maybe by having the program decline handling nodes by exiting with a specific error code?

"Unauthorized request" messages after tinc update
Hello, I have three clients that connect to one server. The server runs tinc 1.0.11 and one client runs tinc 1.0.19. I recently upgraded the two other clients from tinc 1.0.11 to tinc 1.0.16. Since the upgrade, the server now regularly logs messages of the form Aug 26 12:17:42 ebox tinc.rath[4049]: Unauthorized request from hspc (87.173.111.136 port 42836) or Aug 25 18:39:12 ebox

Subnet specification for tinc node as default gateway
Hello, I want to use a tinc node as a default gateway in router mode. My first attempt was to just add an extra, lower priority subnet for the host that should act as the gateway: Subnet = 192.168.12.2/32 Subnet = 0.0.0.0/0#20 but this doesn't seem to work: # route add 173.255.235.238 gw 192.168.12.2 # ping 173.255.235.238 results in the local tinc process complaining that Read packet

"Name" directive in tinc.conf
Hello, According to http://tinc-vpn.org/documentation/tinc_4.html: ,---- | Name = <name> [required] | | This is a symbolic name for this connection.

dovecot-imapd eating 100% cpu every once in a while
Hello, About once or twice a week, dovecot's imap-login process on my system seems gets out of control, eating 100% CPU for about 2 hours. Afterwards everything seems to go back to normal. I am using Dovecot 2.1.7 on a 64 bit Debian wheezy system. When running gdb on the process in this stage, I get the following traceback: #0 0x00007fcba50c5a90 in read () from

How to recognize tinc TCP connection with iptables
Hello, Is there a way to reliably identify a tinc TCP connection using iptables? Looking at the iptables documentation, the u32 test seems to be very flexible (though the "language" of the tests pretty unreadable): u32 U32 tests whether quantities of up to 4 bytes extracted from a packet have specified val? ues. The specification of what to extract is general enough

subnet-up invocations
Hello, I'm confused by the subnet-up calls made by tinc. I was assuming that I'd be called once when it connects to another node. However, subnet-up appears to be called much more often than that. For example, I have the following configuration: ,---- | $ cat tinc.conf | ConnectTo = spitzer | Name = chronos | Mode = switch | | $ cat hbt/hosts/spitzer | address =

tinc never using UDP for data
Hello list, I looked around online but didn't find an answer, so if you can help me out, I'll appreciate I'm trying to create a tinc network which transmits data as UDP and not TCP, because I will pass VoIP traffic on top of it, which would not work fine if using TCP. I have configured tinc between 2 machines and it's working fine, default ports open (UDP 655 and TCP 655) and I

Replication via sneakernet
Is there a way to get a running transaction log from a Dovecot instance to synchronize (and I use that word very, very loosely) multiple instances that don't share a network? Why I would want to do such a thing: I have a couple way stations along a long, winding road through very hilly country, and at each of these stations, I have a few people (and many, many more at one end of the road).

No CRLF in Pigeonhole's header?
Hello, I have been told on Freenode's #dovecot to ask here. I have Exim 4.92 complaining about "Non-CRLF-terminated header, under CHUNKING: message abandoned" with redirects made by Pigeonhole 0.5.5 (with Dovecot 2.3.5.1). Please find relevant part of the traffic below, and help me determine whether Exim is correct on this. ? 0x0000:? 4500 0954 0000 4000 8006 0000 7f00 0001? E..T..

Extracting an object name?
Dear Sir or Madam: This is an extension to a earlier post, about looping through several thousand files, and testing student's models against a different data-set, called rclnow, for "recall now". The problem is, that the instructor never specified to the students, what they should name their "lm" object. So what they created was: "arbitrary variable name"

A problem reading configuration file
Hi! For some time, there is a regression in wine, which disables my Dynatext reader from working. It tries to open it's configuration file but unsuccessfully. The file IS there and former wine versions allowed the program to read it. I was recommended to do a regression tests to find a particular patch but it's too time-expensive for me these days, so I did a full trace and found an

time series comparison
Hi I have 2 time series consisting of sequence of data points measuring flies activity at time intervals of 20 min over a period of 24 hrs. One time series is from control flies while the other is from flies treated with a drug. My question is to find out if the drug has a significant effect on fly activity. What is the appropriate R packages to compare the 2 time series? Thank you for your

Remove objects names like character String
Hi, how can I use rm() on objects named like: paste("site",i,"_data",sep="") while looping through i? I tried rm(paste("site",i,"_data",sep="")) but I get the error that rm() must contain names or text strings which is confusing me as I thought paste() would create something like that...?
