[Iftop-users] Feature request: pppd decapsulation (I think)
by James Lay 25 Sep '20

25 Sep '20

So, I have an interface, eth1, that is used for pppd (connects direct to the modem) that is used to create the ppp0 virtual interface. When using iftop on ppp0, it works great. Sadly sometimes that interface bounces, and iftop stops reporting data after it comes back up. When trying to use iftop on eth1, no data is reported even when ppp0 is up. Can we get iftop to work on ppp0? I hope I explained it well...thank you! James

[Iftop-users] [PATCH v2] Fix minor ui annoyance when ligatures are suported.
by Ariel Popper 25 Sep '20

25 Sep '20

When `iftop` is run under a terminal/font combination that supports ligatures, the "<=" characters form a single, stacked "less than or equal to" glyph rather than an arrow pointing left. This patch replaces "<=" with "<-" along with some others in order to remain visually consistant. --- I'm not sure if anyone cares about this but me, but thought I might share it with whoever wants it. Anyhow, this is a more complete patch than the last one. iftop.8 | 6 +++--- tui.c | 4 ++-- ui.c | 10 +++++----- 3 files changed, 10 insertions(+), 10 deletions(-) diff --git a/iftop.8 b/iftop.8 index 6bc38a7..298d636 100644 --- a/iftop.8 +++ b/iftop.8 @@ -116,12 +116,12 @@ visual indication of traffic.
