Help with pasta usage
by Ayon T 12 May '25

12 May '25

Hi, I've been using pasta as a network driver for rootless docker and I've been running into a couple of issues for a while now. I hope this is where I can find some help troubleshooting. The issue is that when I use pasta as the network driver as opposed to slirp4netns, I'm unable to access the internet through rootless docker or use ping (or traceroute) through its containers. So if I run "docker pull <image-name>" I get a timeout error: > Using default tag: latest Error response from daemon: Get "https://registry-1.docker.io/v2/": dial tcp: lookup registry-1.docker.io on 10.0.2.3:53: read udp 169.254.2.1:58905 ->10.0.2.3:53: i/o timeout I'm running pasta version 0.0~git20250217.a1e48a0-1 on Ubuntu 24.04.2 LTS with docker v27.3.1 build ce12230. Please let me know what other details I could provide to troubleshoot this issue. Thanks and regards, Ayon Tarafdar

pasta - Multiple DNS servers in resolv.conf
by Ben Woods 28 Apr '25

28 Apr '25

Hi Stefano, I have 2 DNS servers listed in the host /etc/resolv.conf - useful during a failure or maintenance of the primary server (even if fallback to the send server is much slower). Can you please advise the best way to get podman containers using pasta to also have the 2 DNS servers? I note that if I don’t provide a —dns-forward option then the resolv.conf file is mapped through from the host, with an additional nameserver 169.254.1.1 added as the first entry above the ones in the host file. Thanks in advance. -- From: Ben Woods

I think reasonable people can disagree on exactly what "transparent" should mean in this context. Mostly we try to make networking inside the container look as much like networking on the host does as possible. Of course, we can't make it 100% alike, so sometimes "as close as possible" is more confusing rather than less. I have ideas for how to rework this in ways that will be both more flexible and (I think) less confusing. However, because there's not a lot of functional difference, it's been a pretty low priority to implement. I hope we can get to it some time, but we don't really have any idea when. > And, albeit with some drawbacks, in general it might also be more > intuitive for users. > > _______________________________________________ > user mailing list -- passt-user(a)passt.top > To unsubscribe send an email to passt-user-leave(a)passt.top -- David Gibson (he or they) | I'll have my music baroque, and my code david AT gibson.dropbear.id.au | minimalist, thank you, not the other way | around. http://www.ozlabs.org/~dgibson

pasta behaviour with multiple NICs
by Ben Woods 25 Apr '25

25 Apr '25

Hi everyone, I'm struggling to understand how pasta will behave when the host has multiple network interfaces. I can't see this mentioned in the website or man page. I'm using pasta with podman if that makes a difference. Example Scenario - 2 interfaces - eth0 (with default route) and eth1 in a different subnet. When the podman container is created, inside the container there is a single interface shown that mimics the eth0 interface name, IP, gateway. If traffic is initiated from the container to an IP within the eth1 subnet - how does pasta make it appear to come from the eth1 IP address? Does it automatically apply NAT to achieve this? If the host has a static route for a subnet not directly connected to either eth0 or eth1, but the static route uses a next hop IP address within the eth1 subnet - will pasta apply NAT to the eth1 IP address, and the use the static route to send it via the next-hop router? Thanks in advance. -- From: Ben Woods
