Enquiry about sods speed

[yanggis]

Hi, firstly, thanks for sharing the great app. May I ask if you test the speed with sods tunnel, for example, max downloading speed? I've tried iodine for DNS tunnel; iodine is stable, but the speed is a bit unsatisfied.

I haven't done a speed test in a while but the speed should be similar to iodine. The main factors will be:

• the rate packets can be sent via the intermediary DNS servers

  For example, if I go directly from the sods client to the sods server, it is fast enough not to notice any lag in a terminal session. When going through an intermediary, depending on the DNS server, the lag can be quite noticeable.

• the amount of data sent in each packet

  NULL DNS records can have the largest payload but aren't widely supported.

• the amount of data

  If I remember correctly, iodine tunnels the data, sending either the whole frame or the IP packet. sods embeds the application data only.

So tl;dr not very fast. Thanks for the question @yanggis !

Dear msantos, Thanks for all clarifications. In fact, I've made an investigation, so wanna to move from iodine to sods. Now, I just use iodine for data transfer via a DNS server, but the speed is only up to 150k/s. May I know how to config sods so that sods can go directly from the sods client to the sods server? I just checked the config file, no tips on how to make this configuration.

You can specify the nameserver using the "-r" flag. For example, if your sods server was 8.8.8.8:

ssh -o ProxyCommand="sdt -r 8.8.8.8 x.o.example.com" 127.0.1.100

Thanks for your fast response. I'll try and let you know the results.
