I have long included tinc in the cerowrt project as a lighter weight, meshy alternative to conventional vpns. I sat down a few days ago to think about how to make vpn connections work better through fq_codel, and decided I should maybe hack on a vpn to do the job. So I picked up tinc's source code for the first time, got it working on IPv6 as a switch in a matter of minutes between two

Dear Community, sorry for the somewhat dumb question. Maybe someone has any pointer to how to setup the RED queue to mark pakets with ECN. In particular what are appropriate parameter settings for limit, min, max, etc. All my trials end up with either "RTNETLINK answers: Invalid argument", although the command line (at least for me) looks fine in regard to what is said on the

I have a Cable ''modem'' that has a problem that many of these devices is bound to have. I was wondering what other lartc user thought about this and if DSL has simular problems. Cable, being Asymetrical, is able to upload at a given rate and hopefully has a buffer, in the modem, of some kind. When I nc(netcat) to a UDP echo, or discard, server I get about 10Mbps out on my

To test the new ECN Shorewall 1.4 feature that I announced recently, I have enabled ECN on my firewall and on my mail/list server. I''ve collected a list of IP addresses that were timing out on email delivery and put them in my /etc/shorewall/ecn file. One user emailed me this morning to say that his version of Short was reporting non-zero reserved bits in SYN packets from

Here is the packet trace - ICMP seems to be coming from my SAMBA Server - see frame 3 Does the netstat output look correct in my first request for help?

Hello, I have been using shorewall for a long time now. I find it a great piece of software and I am looking forward to the IPv6 version that Tom is planning to start working on. I do however have a problem now that I do not seem to be able to solve. On my firewall system I have a Fedora Core 2 installation with Shorewall (2.0.13) running fine with kernel 2.6.6-1.435.2.3. When I however use a new

Dear Users/Developers, I am using a KVM Ubuntu VM as a degrader to apply specific delays to incoming packets. As the delay for my packets can be higher than 7.5 seconds, there is not enough buffer on my interface to buffer all the packets. Therefore those overflowing packets are dropped in the machine and not forwarded. When I tried to use the command ethtool -G ens8 rx 512 to increase the

Hi Michal, What I found was that when I restarted the machine and did a virsh edit command to see the xml config, I see that it is was not actually changed. This suggests why I saw 256 again after restarting. So now I tried again to edit the xml via virsh edit command and used the following to set the parameters. <driver name='qemu' txmode='iothread' ioeventfd='on'

Hi Ashish, I have tested with your xml in the first mail, and it works for rx_queue_size(see below). multiqueue need to work with vhost backend driver. And when you set "queues=1" it will ignored. Please check your qemu-kvm-rhev package, should be newer than qemu-kvm-rhev-2.9.0-16.el7_4.2 And the logs? tx_queue_size='512' will not work in the guest with direct type interface,

I''ve decided to make a late addition to 1.4.0. A number of you have encountered a problem whereby TCP connections could not be established to certain sites. The solution was to turn of Explicit Congestion Notification (ECN -- RFC 3168). I have added a facility whereby ECN may be turned off on a host or network basis. A new /etc/shorewall/ecn file (format is the same as

Good day time! We've noticed the following issue with Samba 3.0.1 on Linux. When SMB client asks for the first time on FID for a locking or read request on an opened file, it causes an ACK to be sent from client side. Windows server also requests ACK BUT much more rarely. Sending ACK causes additional overhead when working in heavy locking and unlocking environment. Windows server

Sambaserver is not accessible I have a problem connecting to SAMBA from Windows/ME systems (using samba--2.2.2 on Red hat Linux 7.1) What I would like to know is - What can I change to get this to work properly? SETUP I have a simple network - three Windows/ME systems and 1 Red Hat Linux 7.1 system all on the same subnet. There is a linksys router on the same subnet that provides WAN

Hello, I replaced an NT4 server by a Samba 3.0.14a ldap server following the instructions in 'Samba by example'. Everything works fine except for some files on a W2003 SP2 server: - when the W2003 server uses the Linux PDC, from a WinXP client, some files are not writable, and ACLs can be listed but not changed. - when the NT4 server is up, the same files on the W2003 server can be
